Infrastructure as Code for AI: Building and Deploying Microsoft Hosted Agents with Terraform
AI agents are no longer experimental. Teams are shipping production-grade agents that retrieve information, call APIs, reason over documents, and orchestrate multi-step workflows at scale. Microsoft Foundry's Hosted Agents service gives you a fully managed runtime for those agents, built on top of the Microsoft Foundry Agent Service, with Microsoft handling the infrastructure, scaling, and runtime lifecycle. The challenge is that provisioning this infrastructure by hand or clicking through the portal, running one-off CLI commands, or relying on undocumented shell scripts, simply does not scale. It introduces configuration drift, makes reproducing environments painful, and creates real governance risk as teams grow. This post walks through how to provision and manage the Azure infrastructure required to run Microsoft Hosted Agents using Terraform. You will leave with working configuration, a clear understanding of the resource model, and practical guidance on where Terraform can take you all the way and where you will need to supplement with the Azure CLI or the Microsoft Foundry Agent Service SDK. What Are Microsoft Hosted Agents? Microsoft Hosted Agents are AI agents deployed and managed within Microsoft Foundry. Microsoft Foundry is Microsoft's unified platform for building, evaluating, and deploying AI applications and agents. It provides: A managed compute runtime — Microsoft provisions and scales the infrastructure so you do not manage VMs or containers. An agent execution environment — agents are defined with instructions, tools (code interpreter, Bing grounding, Azure AI Search, function calling), and a backing model endpoint. Deep Azure integration — identity via Microsoft Entra ID, secrets via Azure Key Vault, storage via Azure Blob, tracing via Azure Monitor and Application Insights. A project-scoped model — each Microsoft Foundry project encapsulates an agent's resources, connections, and deployments within a logical boundary. The "Hosted" distinction matters. You are not running agent code on your own Kubernetes cluster or App Service. Microsoft manages the runtime. Your responsibility is to provision the surrounding infrastructure correctly: the Microsoft Foundry resource, the project, the model deployment, the identity configuration, and the monitoring resources that back it all. That boundary — the infrastructure you own — is exactly what Terraform manages well. Why Terraform for Hosted Agent Deployments? Infrastructure as Code (IaC) is not a new idea, but its importance grows as AI deployments become more complex. Here is why Terraform is a strong choice for Microsoft Foundry deployments specifically: Repeatability: A Terraform configuration produces the same infrastructure every time. Staging mirrors production. Disaster recovery is a terraform apply away. Governance: Infrastructure definitions live in version control alongside application code. Changes are reviewable, auditable, and reversible. This satisfies most enterprise change-management requirements. Scale: Spinning up per-customer or per-team agent environments using Terraform workspaces or module instantiation is far more manageable than manual provisioning. State management: Terraform tracks the actual state of your Azure resources. It detects drift and reconciles it declaratively. Ecosystem: The AzureRM provider is mature, actively maintained by HashiCorp and Microsoft, and covers the majority of Azure services including the Microsoft Foundry resources. Architecture Overview Before writing any Terraform, it helps to understand the resource hierarchy in Microsoft Foundry and how each layer maps to an Azure resource type. The Foundry Resource Hierarchy Microsoft Foundry uses a two-level hierarchy: 1. Foundry Account ( azurerm_cognitive_account , kind: AIServices ) — The top-level AI Services resource. It provides the model endpoint, manages agent execution, and acts as the logical boundary for all projects beneath it. You must set project_management_enabled = true and provide a custom_subdomain_name to enable project creation. In ARM terms this is a Microsoft.CognitiveServices/accounts resource. 2. Foundry Project ( azurerm_cognitive_account_project ) — A child resource scoped within the Foundry Account. Each project has its own agents, model deployments, connections, and data assets. In production, you typically have one project per application, product team, or environment. Figure 1: The Microsoft Foundry resource hierarchy. A single Foundry Account (Cognitive Services, kind AIServices) acts as the top-level container, with Projects scoped beneath it — one per application, team, or environment. Supporting Resources The following Azure resources make up a complete Hosted Agents deployment: Microsoft Foundry Account (AI Services): A single azurerm_cognitive_account of kind AIServices serves as both the Foundry Account and the model endpoint host. Model deployments (e.g. gpt-4.1 ) are provisioned via azurerm_cognitive_deployment within this account. Log Analytics Workspace + Application Insights: Provides observability for agent traces, request logs, and metrics. User-Assigned Managed Identity: Grants the Foundry Account and Projects access to Azure resources without stored credentials. Role Assignments (RBAC): Wires the managed identity to the Foundry Account with least-privilege Cognitive Services permissions. Figure 2: Supporting infrastructure map. The managed identity holds least-privilege RBAC grants to the Microsoft Foundry Account (AI Services) — enabling model access and project management — all within the same resource group. Reference Architecture (Described) A production-ready layout separates concerns across two resource groups: one for shared infrastructure (networking, monitoring) and one for the Microsoft Foundry Account and its projects. The Foundry resource group houses the azurerm_cognitive_account (kind: AIServices) resource and the azurerm_cognitive_account_project instances. The shared resource group holds Log Analytics and Application Insights. A user-assigned managed identity spans both, holding RBAC grants to each backing service. For a dev/test environment you can collapse both into a single resource group. For production, the separation makes cost attribution, access control, and lifecycle management cleaner. Prerequisites Accounts and Permissions An active Azure subscription with the Owner or Contributor + User Access Administrator roles at the subscription or resource group level (role assignments require elevated permission). Foundry access enabled in your subscription. In some tenants you may need to accept terms or request quota for Azure OpenAI. Azure OpenAI quota for the model you intend to deploy (e.g. gpt-4.1 ). Request this via the Azure portal under Quotas in Azure OpenAI Studio. Local Tools Terraform CLI ≥ 1.9 — Install guide Azure CLI ≥ 2.60 — Install guide A code editor (VS Code with the HashiCorp Terraform extension and the Azure Terraform extension is a strong combination). Authentication For local development, authenticate via the Azure CLI. The AzureRM Terraform provider picks this up automatically: az login az account set --subscription "<your-subscription-id>" For CI/CD pipelines, use a service principal with AZURE_CLIENT_ID , AZURE_CLIENT_SECRET , AZURE_TENANT_ID , and AZURE_SUBSCRIPTION_ID environment variables, or — preferably — a workload identity federation (federated credentials) to avoid storing long-lived secrets. GitHub Actions supports OIDC-based workload identity natively. Terraform Fundamentals for Hosted Agents Provider Configuration The hashicorp/azurerm provider is your primary dependency. The new Microsoft Foundry resources ( azurerm_cognitive_account with kind = "AIServices" and azurerm_cognitive_account_project ) require version 4.x of the provider. Pin your version to avoid unexpected breaking changes: terraform { required_version = ">= 1.9" required_providers { azurerm = { source = "hashicorp/azurerm" version = "~> 4.0" } } } provider "azurerm" { features { key_vault { purge_soft_delete_on_destroy = false } resource_group { prevent_deletion_if_contains_resources = true } } subscription_id = var.subscription_id } The features block is required even when empty. The Key Vault setting prevents accidental secret loss during terraform destroy . The resource group setting adds an extra safety net in production. State Management Never use local state for shared or production environments. Store state in Azure Blob Storage with state locking via Azure Blob lease: terraform { backend "azurerm" { resource_group_name = "rg-terraform-state" storage_account_name = "sttfstate<unique>" container_name = "tfstate" key = "ai-agents/prod.tfstate" } } Create the state storage account and container before running terraform init . A bootstrap script or a separate Terraform workspace dedicated to state management are both valid approaches. Known Limitations and Workarounds Terraform coverage of Foundry is improving rapidly but is not yet complete. You should be aware of the following gaps as of mid-2025: Agent definitions are not in Terraform: The actual agent (its system prompt, instructions, tool configuration, and model binding) is created via the Azure AI Agent Service SDK or the Foundry portal, not via Terraform. Terraform provisions the infrastructure; your application code or a post-provisioning script creates the agent. Connections: Some connection types within a Foundry Project (e.g. Azure AI Search, custom connections) may require the Azure CLI or the Foundry SDK. Verify coverage in the AzureRM provider docs before assuming Terraform handles them. Model deployments: azurerm_cognitive_deployment covers OpenAI model deployments and is well-supported. Use this to deploy your model before referencing it from the agent. Private networking: If you need private endpoints for your Foundry Account, additional VNet, subnet, and DNS zone resources are required. This post focuses on the public networking path; private networking is a follow-on topic. Step-by-Step Implementation The following sections build up a complete Terraform configuration. The recommended project structure is a flat module layout for a single environment, with a separate modules/ai-foundry/ directory when you need to reuse the pattern across environments. ai-agents-infra/ ├── main.tf ├── variables.tf ├── outputs.tf ├── versions.tf └── terraform.tfvars 1. Variables Define variables first. Parameterising from the start avoids hard-coded values that create technical debt when you replicate the configuration for staging or production: # variables.tf variable "subscription_id" { type = string description = "Azure subscription ID." } variable "location" { type = string default = "eastus" description = "Azure region for all resources." } variable "environment" { type = string default = "dev" description = "Environment label (dev, staging, prod)." } variable "project_name" { type = string description = "Short name for the project. Used in resource naming." } variable "openai_model_name" { type = string default = "gpt-4.1" description = "Azure OpenAI model to deploy for the agent." } variable "openai_model_version" { type = string default = "2025-04-14" description = "Model version to deploy." } variable "openai_sku_capacity" { type = number default = 10 description = "Tokens-per-minute capacity (in thousands) for the deployment." } 2. Resource Group and Core Infrastructure A single resource group keeps things simple for dev. In production, consider splitting as described in the architecture section above. # main.tf — Resource group and naming locals locals { name_prefix = "${var.project_name}-${var.environment}" tags = { environment = var.environment project = var.project_name managed_by = "terraform" } } resource "azurerm_resource_group" "main" { name = "rg-${local.name_prefix}" location = var.location tags = local.tags } 3. Supporting Services Provision Log Analytics and Application Insights for agent observability and diagnostics. Unlike the legacy Hub-based architecture, the azurerm_cognitive_account (kind AIServices ) does not require a dedicated Storage Account or Key Vault as provisioning dependencies. # main.tf — Monitoring infrastructure data "azurerm_client_config" "current" {} # Log Analytics Workspace (required by Application Insights) resource "azurerm_log_analytics_workspace" "main" { name = "law-${local.name_prefix}" resource_group_name = azurerm_resource_group.main.name location = azurerm_resource_group.main.location sku = "PerGB2018" retention_in_days = 30 tags = local.tags } # Application Insights for agent observability resource "azurerm_application_insights" "main" { name = "appi-${local.name_prefix}" resource_group_name = azurerm_resource_group.main.name location = azurerm_resource_group.main.location workspace_id = azurerm_log_analytics_workspace.main.id application_type = "web" tags = local.tags } 4. User-Assigned Managed Identity A managed identity allows the Foundry Account and its projects to authenticate to Azure services without stored credentials. This is a security best practice and is required for several Microsoft Foundry features. # main.tf — Managed identity for the Microsoft Foundry Account resource "azurerm_user_assigned_identity" "foundry" { name = "id-${local.name_prefix}-foundry" resource_group_name = azurerm_resource_group.main.name location = azurerm_resource_group.main.location tags = local.tags } 5. Microsoft Foundry Account and Model Deployment In the current Microsoft Foundry architecture, a single azurerm_cognitive_account of kind AIServices serves as both the Foundry Account and the model endpoint host. Set project_management_enabled = true and provide a globally unique custom_subdomain_name to enable Foundry Project creation beneath it. # main.tf — Microsoft Foundry Account (AI Services) resource "azurerm_cognitive_account" "foundry" { name = "aisa-${local.name_prefix}" resource_group_name = azurerm_resource_group.main.name location = azurerm_resource_group.main.location kind = "AIServices" sku_name = "S0" project_management_enabled = true custom_subdomain_name = "${replace(local.name_prefix, "-", "")}foundry" tags = local.tags identity { type = "UserAssigned" identity_ids = [azurerm_user_assigned_identity.foundry.id] } } # Deploy the model within the Foundry Account resource "azurerm_cognitive_deployment" "agent_model" { name = var.openai_model_name cognitive_account_id = azurerm_cognitive_account.foundry.id model { format = "OpenAI" name = var.openai_model_name version = var.openai_model_version } sku { name = "Standard" capacity = var.openai_sku_capacity } } Note on quota: The capacity value is in thousands of tokens per minute. A value of 10 means 10,000 TPM. If terraform apply fails with a quota error, reduce this value or request a quota increase via the Azure portal. Note on custom_subdomain_name : This must be globally unique across all Azure AI Services accounts. If provisioning fails with a conflict error, adjust the suffix (e.g. append a random string using the random_string resource). 6. Foundry Project Create a Foundry Project beneath the Foundry Account provisioned in Step 5. Each project scopes its own agents, model connections, and data assets. Use one project per application or team. # main.tf — Microsoft Foundry Project resource "azurerm_cognitive_account_project" "agent_project" { name = "proj-${local.name_prefix}-agents" cognitive_account_id = azurerm_cognitive_account.foundry.id location = azurerm_resource_group.main.location display_name = "Agent Project - ${var.project_name}" description = "Hosted agents project for ${var.project_name}" identity { type = "UserAssigned" identity_ids = [azurerm_user_assigned_identity.foundry.id] } tags = local.tags } 7. RBAC Role Assignments Grant the managed identity the permissions it needs. This is the area most commonly misconfigured in manual deployments. Terraform makes it explicit and auditable. # main.tf — RBAC assignments # AI Services: Foundry identity needs Cognitive Services OpenAI User to call model endpoints resource "azurerm_role_assignment" "foundry_openai" { scope = azurerm_cognitive_account.foundry.id role_definition_name = "Cognitive Services OpenAI User" principal_id = azurerm_user_assigned_identity.foundry.principal_id } # AI Services: Foundry identity needs Cognitive Services Contributor to manage projects resource "azurerm_role_assignment" "foundry_contributor" { scope = azurerm_cognitive_account.foundry.id role_definition_name = "Cognitive Services Contributor" principal_id = azurerm_user_assigned_identity.foundry.principal_id } # Optional: grant your own principal the Azure AI Developer role on the Foundry Account # so you can create and manage agents from your local machine or CI pipeline resource "azurerm_role_assignment" "developer_account" { scope = azurerm_cognitive_account.foundry.id role_definition_name = "Azure AI Developer" principal_id = data.azurerm_client_config.current.object_id } 8. Outputs Export the values your application and post-provisioning scripts will need: # outputs.tf output "resource_group_name" { value = azurerm_resource_group.main.name } output "foundry_account_id" { value = azurerm_cognitive_account.foundry.id } output "ai_foundry_project_id" { value = azurerm_cognitive_account_project.agent_project.id } output "foundry_endpoint" { value = azurerm_cognitive_account.foundry.endpoint } output "openai_deployment_name" { value = azurerm_cognitive_deployment.agent_model.name } output "managed_identity_client_id" { value = azurerm_user_assigned_identity.foundry.client_id } 10. Example terraform.tfvars # terraform.tfvars — do NOT commit this file if it contains sensitive values subscription_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" location = "eastus" environment = "dev" project_name = "contoso-agents" openai_model_name = "gpt-4.1" openai_model_version = "2025-04-14" openai_sku_capacity = 10 Figure 3: Terraform deployment workflow. State is stored in an Azure Blob Storage backend, enabling team collaboration and preventing concurrent apply conflicts. Deploying and Validating the Agent Infrastructure Running the Deployment # 1. Initialise — downloads provider plugins and configures the backend terraform init # 2. Validate syntax and configuration terraform validate # 3. Preview what will be created (review carefully before applying) terraform plan -out=tfplan # 4. Apply the plan terraform apply tfplan A full initial apply typically takes 8–15 minutes. The Foundry Account (AI Services) provisioning is the longest step. The model deployment may also take a few minutes to reach a ready state — Terraform handles this with implicit dependency ordering, but you may see brief retries in the output. Verifying the Deployment After apply completes, verify each resource is in a healthy state: # Confirm the resource group and its resources exist az resource list --resource-group "rg-contoso-agents-dev" --output table # Check the Foundry Account (AI Services) is in a Succeeded state az cognitiveservices account show \ --name "aisacontosoagentsdevfoundry" \ --resource-group "rg-contoso-agents-dev" \ --query "properties.provisioningState" # Confirm the model deployment is ready az cognitiveservices account deployment show \ --resource-group "rg-contoso-agents-dev" \ --name "aisacontosoagentsdevfoundry" \ --deployment-name "gpt-4.1" \ --query "properties.provisioningState" Navigate to the Microsoft Foundry portal and confirm your Foundry Account and Project appear. At this point you can create an agent manually in the portal to validate that the model endpoint is reachable and the identity chain works correctly before automating agent creation. Common Deployment Issues Quota exceeded on model deployment: Reduce openai_sku_capacity or request a quota increase in the Azure portal under Azure OpenAI → Quotas. Resource name conflicts: The custom_subdomain_name on the Foundry Account must be globally unique. Use the random_string Terraform resource to append a unique suffix if needed. Role assignment propagation delay: RBAC changes can take 1–2 minutes to propagate. If the Foundry Account cannot access resources immediately after apply, wait a moment and retry. project_management_enabled not set: If azurerm_cognitive_account_project fails with an error about project management, ensure project_management_enabled = true and custom_subdomain_name are set on the parent azurerm_cognitive_account . azurerm_cognitive_account_project not found: Ensure your AzureRM provider version is ~> 4.0 or later. Run terraform init -upgrade if you previously initialised with an older version. Creating an Agent After Infrastructure Provisioning Terraform has provisioned the platform. Now you need to create the agent itself. This is done via the Azure AI Agents SDK (available for Python, C#, JavaScript, and Java) or the Foundry portal. The following Python snippet demonstrates creating a basic agent programmatically after Terraform apply. It uses the outputs from Terraform directly: import os from azure.ai.projects import AIProjectClient from azure.identity import DefaultAzureCredential # These values come from Terraform outputs project_connection_string = os.environ["AI_PROJECT_CONNECTION_STRING"] model_deployment = os.environ["OPENAI_DEPLOYMENT_NAME"] client = AIProjectClient.from_connection_string( credential=DefaultAzureCredential(), conn_str=project_connection_string, ) # Create the hosted agent agent = client.agents.create_agent( model=model_deployment, name="customer-support-agent", instructions=( "You are a helpful customer support assistant. " "Answer questions accurately and concisely. " "If you are unsure, say so rather than guessing." ), ) print(f"Agent created: {agent.id}") Figure 5: Agent runtime architecture. The Foundry Project hosts the Agent Service, which routes requests to the GPT-4.1 model endpoint and optionally invokes tool integrations (Code Interpreter, File Search, Azure Functions, or custom tools). The project connection string is available from the Foundry portal (Project → Overview → Project connection string) or can be constructed from Terraform outputs. Refer to the Azure AI Agents quickstart for the full SDK setup. Operational Considerations Lifecycle Management Terraform's declarative model means updates are incremental by default. To update the OpenAI model version, change openai_model_version in your .tfvars file and run terraform plan to confirm the change before applying. Terraform will delete and recreate the cognitive deployment in-place — be aware this causes brief downtime for the model endpoint. To destroy a complete environment: terraform destroy The prevent_deletion_if_contains_resources feature on the resource group will block destruction if any untracked resources exist, which is a useful safety net in production. Handling Configuration Drift Drift occurs when Azure resources are modified outside of Terraform (portal changes, CLI scripts, other automation). Detect drift with: terraform plan -refresh-only This reports the difference between the Terraform state and the actual resource state without making changes. Schedule this as a drift-detection job in CI to catch out-of-band changes early. Environment Isolation Use Terraform workspaces or separate state files per environment: # Create and switch to a staging workspace terraform workspace new staging terraform workspace select staging terraform apply -var-file="environments/staging.tfvars" Alternatively, use a directory-per-environment layout ( environments/dev/ , environments/prod/ ) with a shared module in modules/ai-foundry/ . The directory layout is more explicit and easier to navigate in a team setting. Cost Control Set a low openai_sku_capacity in dev (e.g. 1 = 1,000 TPM) to limit accidental spend. Tag all resources with environment and project tags (the locals.tags block handles this) to enable cost attribution in Azure Cost Management. Use the Azure Pricing Calculator to estimate monthly costs before deploying to production. The Azure AI Services account (model token usage), Log Analytics, and Application Insights are the primary cost drivers. Consider destroying dev environments overnight using a scheduled CI job that runs terraform destroy and terraform apply on a schedule. CI/CD Integration Automating Terraform via GitHub Actions is straightforward. The following workflow runs plan on pull requests and apply on merge to the main branch: # .github/workflows/terraform.yml name: Terraform Deploy on: push: branches: [main] pull_request: branches: [main] permissions: id-token: write # Required for OIDC workload identity federation contents: read pull-requests: write env: ARM_CLIENT_ID: ${{ secrets.AZURE_CLIENT_ID }} ARM_TENANT_ID: ${{ secrets.AZURE_TENANT_ID }} ARM_SUBSCRIPTION_ID: ${{ secrets.AZURE_SUBSCRIPTION_ID }} ARM_USE_OIDC: "true" jobs: terraform: runs-on: ubuntu-latest environment: ${{ github.ref == 'refs/heads/main' && 'production' || 'staging' }} steps: - uses: actions/checkout@v4 - uses: hashicorp/setup-terraform@v3 with: terraform_version: "~1.9" - name: Terraform Init run: terraform init - name: Terraform Plan run: terraform plan -out=tfplan -var-file="environments/dev.tfvars" - name: Terraform Apply if: github.ref == 'refs/heads/main' run: terraform apply -auto-approve tfplan Figure 4: CI/CD pipeline using GitHub Actions with OIDC workload identity federation. No long-lived secrets are stored — the runner exchanges a JWT for a short-lived Azure token before each Terraform run. Use OIDC workload identity federation to avoid storing long-lived service principal secrets in GitHub. This is the recommended authentication method for GitHub Actions deployments to Azure. Best Practices Modular Terraform Design Once you have a working flat configuration, extract the Foundry resources into a reusable module. A module boundary around the Hub, Project, OpenAI account, and RBAC assignments lets you stamp out new agent environments with a single module call and a new .tfvars file. # environments/staging/main.tf module "agent_platform" { source = "../../modules/ai-foundry" project_name = "contoso-agents" environment = "staging" location = "eastus" subscription_id = var.subscription_id openai_model_name = "gpt-4.1" openai_model_version = "2025-04-14" openai_sku_capacity = 30 } Parameterisation and Environment Configs Never hard-code subscription IDs, tenant IDs, or region names in main.tf . Keep environment-specific values in environments/<env>.tfvars files and commit them to source control (they are config, not secrets). Store actual secrets (service principal credentials, API keys for third-party connections) in Azure Key Vault or GitHub Secrets — not in .tfvars files. Versioning Models and Agent Configurations Treat your openai_model_version and agent instructions as versioned artefacts. When Microsoft releases a new model version, create a pull request that updates the variable value, runs a plan, and documents the expected change. This creates a clear history of when model versions changed and who approved the change. Logging and Monitoring Enable diagnostic settings on the Azure OpenAI account to route request logs and metrics to your Log Analytics workspace. Use Application Insights to capture agent traces from the Azure AI Agents SDK (it integrates with OpenTelemetry). Set up Azure Monitor alerts on OpenAI account errors (4xx/5xx rates) and Log Analytics ingestion failures. Responsible AI Considerations Enable Azure OpenAI content filtering on your deployment. Terraform supports this via the content_filter block in azurerm_cognitive_deployment where the policy allows. Define a clear system prompt that sets agent behaviour boundaries and instructs the agent to decline harmful requests. Log and review agent conversations during early deployment. Microsoft Foundry includes evaluation tools for assessing agent response quality and safety. Apply least-privilege RBAC throughout — the role assignments in this post follow that principle. Conclusion and Next Steps You now have a complete, repeatable Terraform configuration for provisioning the Azure infrastructure required to run Microsoft Hosted Agents via Microsoft Foundry. The key takeaways: Terraform manages the infrastructure layer effectively — the Foundry Account, Project, model deployment, identity, and RBAC. Agent definitions themselves are provisioned via the Azure AI Agents SDK or the Foundry portal as a post-Terraform step. State management, parameterisation, and modular design are non-negotiable for team environments. OIDC-based workload identity is the right authentication model for CI/CD pipelines. Drift detection, environment isolation, and cost tagging are operational necessities, not optional extras. Where to Go Next Add Azure AI Search: Extend the Foundry Project with an Azure AI Search connection and enable the Search tool on your agent for Retrieval-Augmented Generation (RAG). Private networking: Add private endpoints for the Foundry Hub and OpenAI account to lock down ingress to your VNet. Multi-region deployment: Instantiate the Terraform module twice with different regions and use Azure Traffic Manager or Front Door to route requests. GitOps for agents: Store agent definitions (system prompts, tool configurations) as YAML or JSON in your repository and use a CI pipeline to apply them via the Azure AI Agents SDK on every merge, creating a fully declarative agent deployment pipeline. Evaluation pipelines: Use Microsoft Foundry's built-in evaluation capabilities to run automated quality and safety assessments on every new model version or prompt change.

Building a GitHub Copilot Agent Usage Dashboard
Introduction Working with organisations that are attempting to create GitHub Copilot custom agents, take-up of these agents by their community becomes important to know. Some questions quickly emerge are "how well are we actually using it?", "which agents are getting used and which have not had that much traction?". Native metrics provide high-level insights into adoption, but they lack the depth needed to answer more granular questions—such as which agent workflows are most used, or how behaviour evolves over time. In this post, I’ll walk through how to build an enterprise-grade GitHub Copilot usage dashboard that captures detailed telemetry from VS Code using OpenTelemetry, processes it in Azure Monitor, and visualises insights in Grafana—all using a reproducible, infrastructure-as-code approach. The dashboard can be made available to anyone that needs it. Architecture VS Code can be configured to emit metrics using Open Telemetry as a standard. This is a configuration item in VS Code and you essentially point it to an Open Telemetry Collector. The collector is an endpoint that can consume the telemetry. In this implementation, it is a container image that is hosted in Azure and I have chosen Azure Container Apps (ACA) for this purpose as it is an easy to use managed environment - but it could also run in Azure Kubernetes Service (AKS) with a little more effort. There is a prebuilt image opentelemetry collector for this and this has been adapted to inject configuration to send the telemetry to Azure Application Insights. For defining and hosting the dashboard, I have chosen another Azure managed service Azure Managed Grafana Sample Dashboard The sample dashboard is one that contains a collection of visualisations derived from the collected data in Application Insights. Azure Managed Grafana allows you to visually author these dashboards or they can be implemented as a JSON file and adapted from there. Note that the telemetry generated by VS Code gives the location of the users - city, region and country, but does not include any personally-identifying information (PII) and so cannot be used to track individuals. As I understand it, this is by design. Managed Grafana has its own permission structure, which may then be used to give users access to the dashboard. Implementation Details There is a GitHub repo Copilot Usage Dashboard that contains details of how to implement this together with instructions for either "click-ops" 🙂creation or via Terraform. So I suggest you follow the link to my repo to look at the details. In summary, there needs to be in Azure: Azure Container App (ACA) that hosts the collector - this needs to have public ingress Azure Container Registry (ACR) that hosts the docker image that is customised via the Dockerfile Key Vault that hosts the Application Insights connection string that ACA references Application Insights - this needs to be created with a flag to allow it to work with Grafana data Log Analytics Workspace that works with Application Insights Azure Managed Grafana to host the Grafana dashboard The main thing to bear in mind is that VS Code needs to be configured to emit OpenTelemetry { "github.copilot.nextEditSuggestions.enabled": true, "github.copilot.chat.otel.enabled": true, "github.copilot.chat.otel.exporterType": "otlp-http", "github.copilot.chat.otel.otlpEndpoint": "https://<fqdn>" } where the FQDN is the URL of the public ingress to the Azure Container App. There is a Dockerfile in this repo that just injects the correct configuration file into the OpenTelemetry collector image. It is this configuration file that tells the collector to emit to Application Insights. It is of the form below: receivers: otlp: protocols: grpc: endpoint: 0.0.0.0:4317 http: endpoint: 0.0.0.0:4318 processors: batch: attributes: actions: - key: environment value: "prod" action: upsert exporters: azuremonitor: connection_string: "${APPLICATIONINSIGHTS_CONNECTION_STRING}" debug: verbosity: detailed service: pipelines: traces: receivers: [otlp] processors: [batch, attributes] exporters: [azuremonitor, debug] metrics: receivers: [otlp] processors: [batch, attributes] exporters: [azuremonitor] As can be seen above, there is a placeholder for the Application Insights connection string - in the ACA configuration this is an environment variable that then points to a secret which is in key vault. If all is well, VS Code will emit telemetry to the container image running in ACA and this will use its configuration to send to Application Insights. The Grafana dashboard then using this data. Troubleshooting The GitHub repo goes into the detail of troubleshooting, but the overall steps to troubleshoot are: If there is no data in Grafana, check that Grafana has access to Application Insights check whether there is telemetry being pushed into Application Insights by looking at the logs and looking for the contents of the table Dependencies. If there is telemetry there, then it is Grafana permissions. If not, look to ACA Look at ACA logs to see if it is healthy and look to see if there is any logs being received Use a curl request to send a fake log to ACA (a sample is in the repo) to see if the ACA is accepting logs Check the connection to Application Insights is correct and is being pulled from key vault or replace the environment variable value with the connection string directly If all good so far, then it may be that the configuration in VS Code is not correct or in the correct place. Hopefully the more detailed steps will resolve any issues quickly. Further thoughts and enhancements This implementation attempts to build a dashboard showing GitHub Copilot agent usage using a standard set of security controls, but more may be needed. Here is a list of possible enhancements: A more refined dashboard. This should be easy as there are samples for all sorts of visualisations and few of these may allow more focus on agent and model usage. the ACA-hosted OpenTelemetry collector has a public-facing ingress. This may need to be locked-down at the network level by address restriction or by a non-public ingress. Care would need to be taken to make sure that this is then visible/reachable to the intended VS Code user audience The ACA collector endpoint is not authenticated in of itself. This could be achieved at the container level by putting an authenticating proxy in the Dockerfile or at the ACA ingress level. Some investigation would be needed to see how the VS Code configuration could work with this and this may dictate largely what form this authentication can take. How the VS Code configuration changes can be automated for a user base has not been investigated as part of this work. It is assumed that an organisation may be able to roll-out these changes using their application deployment automation. Summary This approach provides a means by which an organisation can track the usage of GitHub Copilot agents (and their models), that is not provided by GitHub Enterprise dashboards. This will provide insights into the take up of custom agents and their underlying models - allowing an organisation to test whether their investments on custom agents are being used effectively. Additionally, the dashboards themselves can easily be rolled-out to a wider community than GitHub Enterprise one.Building and Operating a Microsoft Foundry Hosted Agent with GitOps and GitHub Tasks
The Gap Between Prototype and Production Most AI engineering teams can build a working agent in a day. The hard part is not building it; the hard part is operating it. Prompts drift. Tool configurations change without review. Deployments happen from someone's laptop. There is no audit trail, no rollback plan, and no consistent way to promote a change from a development environment to production. GitOps closes that gap. By treating your agent definition, configuration, and infrastructure as version-controlled source code, you get the same delivery discipline that software engineering teams have applied to application code for years. Every change is reviewed, every deployment is automated, and every environment state is traceable to a specific commit. This post shows you how to apply GitOps principles to a Microsoft Foundry Hosted Agent using GitHub as the source of truth and GitHub Tasks and Actions as the automation layer. The result is a repeatable, governed, production-ready delivery model for AI agents. What Is a Microsoft Foundry Hosted Agent? Microsoft Foundry is Microsoft's platform for building, deploying, and operating AI applications and agents. A Hosted Agent is an agent runtime managed by the Foundry platform rather than self-hosted by your team. You supply the agent logic, configuration, and tools; Foundry handles the runtime lifecycle, scaling, and managed infrastructure. In practical terms, a Foundry Hosted Agent is a containerised agent application. You package your agent code, prompt definitions, tool bindings, and environment configuration into a container image. Foundry deploys and manages that container within a Foundry project, connected to models, tools, and observability infrastructure that the platform provides. Teams choose Hosted Agents over self-hosting because: The platform manages runtime infrastructure, patching, and scaling Integration with Azure AI models, managed identity, and observability is built in You can focus engineering effort on agent logic rather than cluster management Foundry projects provide environment and resource isolation without requiring you to provision and manage separate Azure resources for each environment Hosted Agents are a good fit when your team wants strong operational support with minimal platform overhead, when you need clear separation between environments, and when your agents depend on Azure AI capabilities such as Azure OpenAI Service, Azure AI Search, or Model Context Protocol integrations. Why GitOps Matters Specifically for AI Agents GitOps is straightforward for stateless web services: the code changes, the pipeline runs, the container is deployed. AI agents are more complex because there are multiple distinct artefacts that all affect agent behaviour: System prompts and instruction files Tool definitions and external integrations Model selection and configuration (temperature, max tokens, safety settings) Model Context Protocol (MCP) server definitions Orchestration logic and agent workflow code Safety and policy settings Infrastructure and deployment configuration Any one of these can change the behaviour of your agent in ways that are difficult to detect without structured review. A prompt change that looks harmless can alter tone, scope, or factual grounding. A tool configuration change can expose data to unintended callers. A model upgrade can shift response quality unpredictably. Git gives you a single place to version, review, and approve all of these artefacts together. Pull requests give you a structured review gate. Workflow automation gives you validation before anything reaches a deployed environment. Tags and releases give you deployment markers you can roll back to. The discipline of GitOps turns what is often an ad-hoc AI delivery process into a repeatable engineering practice. Reference Architecture The following diagram shows a practical reference architecture for delivering a Microsoft Foundry Hosted Agent through a GitOps model using GitHub. +---------------------------+ | GitHub Repository | | /src /agents /tools | | /prompts /infra | | /.github/workflows | +---------------------------+ | | Pull Request / Push to main v +---------------------------+ | GitHub Actions | | 1. Validate agent config | | 2. Lint and scan code | | 3. Run unit tests | | 4. Build container image | | 5.

The following structure works well in practice: my-foundry-agent/ ├── .github/ │ ├── workflows/ │ │ ├── validate.yml # Runs on every PR │ │ ├── build-deploy.yml # Runs on merge to main │ │ └── rollback.yml # Manual trigger workflow │ └── CODEOWNERS # Review assignments by path ├── src/ │ ├── agents/ │ │ ├── agent.py # Agent entry point and orchestration │ │ └── agent_config.json # Agent metadata and settings │ ├── tools/ │ │ ├── search_tool.py # Tool implementations │ │ └── data_tool.py │ └── prompts/ │ ├── system.txt # System prompt (versioned as plain text) │ └── instructions.txt # Supplementary instructions ├── tests/ │ ├── unit/ # Unit tests for tools and logic │ ├── integration/ # Integration tests against a running agent │ └── smoke/ # Post-deployment smoke tests ├── infra/ │ ├── main.bicep # Foundry project and resource definitions │ └── environments/ │ ├── dev.parameters.json │ ├── test.parameters.json │ └── prod.parameters.json ├── scripts/ │ ├── validate_agent.py # Config validation script │ └── smoke_test.py # Smoke test runner ├── Dockerfile # Container image definition └── docs/ └── architecture.md # Architecture and runbook documentation What belongs where and why: /src/prompts - System prompts as plain text files. Versioning prompts as files means every change goes through a pull request with a diff review, just as code does. /src/agents - Agent orchestration logic and configuration. Keeps the entry point and agent metadata co-located. /src/tools - Tool implementations separated from agent logic. Tool logic changes independently and should be reviewable in isolation. /infra - Infrastructure as code with per-environment parameter files. Environment-specific values live here, never in source files. /tests - Three layers of testing: unit tests for tools, integration tests for the full agent, and smoke tests that run against a deployed environment. /.github/workflows - All automation defined as code. There should be no manual deployment steps that live outside this directory. GitHub Tasks Across the Delivery Lifecycle GitHub Tasks and Issues provide the work tracking layer on top of the GitOps delivery model. Used well, they connect the intention behind a change to its implementation and deployment history. Practical patterns for using GitHub Tasks with agent delivery: Prompt change task - Open an issue to describe why the system prompt is changing. The pull request that changes system.txt closes that issue, creating a permanent link between the rationale and the diff. Tool integration task - When adding a new MCP server or external tool integration, create a task that captures the design decision, security review outcome, and test evidence before the pull request is merged. Model upgrade task - When upgrading the underlying model version, create a task that includes evaluation results and comparison data. The task becomes part of your change audit trail. Rollback task - If a deployment causes quality regressions, create a task to track the rollback, root cause investigation, and corrective action. Automation can open this task automatically when a deployment fails health checks. Dependency on approval - GitHub Tasks can be linked to environment approvals in GitHub Actions. A task in a specific milestone or project column can gate a promotion workflow. The key insight is that GitHub Tasks are not just work management; they are part of your audit trail. A regulatory or security reviewer can follow the chain from a production deployment back through workflow runs, pull request reviews, and the original task that described the intent of the change. End-to-End GitOps Flow The following walk-through describes a realistic developer experience for changing an agent prompt and promoting it to production. A developer opens a GitHub Issue describing the prompt change required and the expected behaviour improvement. The developer creates a feature branch, edits src/prompts/system.txt , and updates any related unit tests. A pull request is opened. The validate workflow runs immediately, checking prompt length, configuration schema, and lint rules. Unit tests run against the changed files. A code reviewer approves the pull request. The CODEOWNERS file ensures that prompt changes require review from the AI engineering team, not just any contributor. On merge to main, the build workflow runs: the container image is built with the new prompt baked in, tagged with the commit SHA, and pushed to Azure Container Registry. The deployment workflow deploys the new image to the Foundry Dev project automatically. Integration and smoke tests run against the deployed dev agent. If tests pass, the workflow pauses at the Test environment gate and requests approval from a named reviewer. After approval, the same image is deployed to Foundry Test. Smoke tests run again. A second approval gate controls promotion to Foundry Prod. If at any point a health check or smoke test fails, the rollback workflow redeploys the previous image tag from the registry. The image tag of the last known-good deployment is stored as a GitHub environment variable. This flow means that no human ever deploys directly to any environment. Every environment state is traceable to a specific commit, image tag, and workflow run. Security and Governance AI agents often have access to sensitive data and external systems. Security and governance cannot be an afterthought. Identity and Access Use managed identity for the Foundry Hosted Agent to access Azure resources. Avoid service principal secrets where Microsoft Entra Workload Identity or managed identity is available. Apply the principle of least privilege: the agent identity should have read access to data sources and limited write access only where the use case requires it. Tool integrations that require API keys or external credentials should retrieve them from Azure Key Vault at runtime, never from environment variables baked into the image. Secrets and Configuration Store secrets in Azure Key Vault. Reference them in your Foundry project configuration using Key Vault references. Store GitHub Actions secrets using repository or environment-scoped secrets. Never echo secrets in workflow logs. Separate environment configuration (endpoints, resource names, capacity settings) from agent logic. Use the /infra/environments/ parameter files for this. Auditability and Review Enforce pull request reviews for all changes to /src/prompts , /src/agents , and /infra via CODEOWNERS. Require status checks to pass before merging. Blocked merges prevent untested changes reaching production. GitHub's workflow run history gives you a complete deployment audit trail. You can answer "what was deployed to prod on Tuesday and who approved it" in seconds. For regulated environments, consider branch protection rules that require signed commits. Safe Rollout Use canary or blue-green patterns where Foundry supports them for high-traffic agents. Always keep the previous image tag available in the registry. Do not delete images on deployment. Document and test your rollback procedure before you need it in production. Observability and Operational Readiness A deployed agent that you cannot observe is an agent you cannot operate. Build observability in from the start. What to Monitor Deployment health - Track whether each Foundry deployment succeeded and the agent is responding. Wire deployment outcomes back to GitHub workflow run status. Model and tool errors - Log tool call failures, model timeout errors, and safety filter activations. Aggregate these in Azure Monitor or Application Insights. Latency - Track end-to-end response latency per agent version. A latency increase after a model or prompt change is an early signal of a quality regression. Token consumption - Monitor token usage per request and per session. Unexpected increases can indicate prompt injection or runaway orchestration loops. Traceability - Log which agent version handled each request. Correlation between the image tag and request traces is essential for debugging production issues. Debugging and Alerting Use structured logging with a consistent schema. Include fields for agent version, session ID, tool called, and outcome. Set up alerts for error rate thresholds and latency percentiles. Alert before users notice the problem. For failed agent runs, ensure logs capture the full conversation context (within your data retention policy) so that developers can reproduce and diagnose the failure. Microsoft Foundry Toolboxes One of the most important additions to the Foundry platform is Toolboxes, currently in Public Preview. If you have ever seen an agent codebase where three different agents each wire the same search tool with their own credentials and slightly different configurations, you already understand the problem Toolboxes solve. A Toolbox is a named, versioned bundle of tools managed centrally in Microsoft Foundry. You define the tools once, configure authentication and access centrally, and publish a single MCP-compatible endpoint. Any agent in any runtime consumes that endpoint without per-tool wiring, custom SDK integration, or duplicated credential management. Figure: Before and after Foundry Toolboxes. Each agent previously managed its own tool connections. With Toolboxes, agents connect to one governed endpoint. The Four Pillars Discover (coming soon) - Find approved tools without browsing long catalogues. Reduces duplication by surfacing what already exists before developers build something new. Build (available today) - Select tools into a named toolbox. Supported types include built-in tools (Web Search, Code Interpreter, File Search, Azure AI Search), MCP servers, Agent-to-Agent (A2A) endpoints, and OpenAPI-defined services. Consume (available today) - A single MCP-compatible endpoint exposes every tool in the toolbox to any agent runtime. Agents that can speak MCP can use a Foundry Toolbox without any Foundry-specific SDK dependency. Govern (coming soon) - Centralised authentication and observability applied to every tool call flowing through the toolbox. Security and platform teams get consistent controls without asking developers to bolt governance onto every agent individually. Toolboxes and GitOps: A Natural Fit Toolboxes are particularly well-suited to a GitOps delivery model because the toolbox definition is a discrete, versioned artefact. Instead of credentials and tool configuration scattered across agent codebases, the toolbox becomes its own managed entity with its own version history. The key design property is that the toolbox endpoint URL is stable. When you promote a new toolbox version to be the default, agents consuming the endpoint pick up the update without any code changes. This means you can update tool configuration, add a new MCP server, or rotate credentials in the toolbox without redeploying every agent that uses it. Figure: Toolbox versioning in a GitOps model. Commits trigger CI validation and deployment of new toolbox versions. The stable endpoint URL allows agents to consume updates without redeployment. Adding a Toolbox to Your Repository In your GitOps repository, toolbox definitions belong in /src/tools/toolbox_config.py or as a declarative configuration file checked into version control. The following example creates a toolbox that combines web search, Azure AI Search over internal documentation, and a GitHub MCP server: # src/tools/toolbox_config.py # Run this via CI to create or update a toolbox version in Foundry. from azure.identity import DefaultAzureCredential from azure.ai.projects import AIProjectClient import os client = AIProjectClient( endpoint=os.environ["FOUNDRY_PROJECT_ENDPOINT"], credential=DefaultAzureCredential() ) toolbox_version = client.beta.toolboxes.create_toolbox_version( toolbox_name="customer-feedback-toolbox", description="Tools for triaging customer feedback: search, docs, and GitHub.", tools=[ { "type": "web_search", "description": "Search approved public documentation sites.", "custom_search_configuration": { "project_connection_id": os.environ["BING_CONNECTION_NAME"], "instance_name": os.environ["BING_INSTANCE_NAME"] } }, { "type": "azure_ai_search", "name": "product-manuals-search", "description": "Search internal product documentation.", "azure_ai_search": { "indexes": [ { "index_name": os.environ["SEARCH_INDEX_NAME"], "project_connection_id": os.environ["SEARCH_CONNECTION_ID"] } ] } }, { "type": "mcp", "server_label": "github", "server_url": "https://api.githubcopilot.com/mcp", "project_connection_id": os.environ["GITHUB_CONNECTION_ID"] } ], ) print(f"Toolbox version created: {toolbox_version.version}") print(f"MCP endpoint: {toolbox_version.mcp_endpoint}") To promote a toolbox version to be the default (the endpoint agents use without specifying a version), add this to your deployment workflow: # Promote toolbox version to default after validation toolbox = client.beta.toolboxes.update( toolbox_name="customer-feedback-toolbox", default_version=toolbox_version.version, ) print(f"Default version is now: {toolbox.default_version}") The stable endpoint for agents consuming this toolbox is: https://<your-project>.services.ai.azure.com/api/projects/<project>/toolbox/customer-feedback-toolbox/mcp?api-version=v1 Attaching the Toolbox to Your Hosted Agent In your agent code, connect to the toolbox via a single MCP tool definition. The agent gains access to every tool in the toolbox without knowing their individual configurations: # src/agents/agent.py (relevant excerpt) from agent_framework import MCPStreamableHTTPTool import httpx, os toolbox_endpoint = os.environ["FOUNDRY_TOOLBOX_ENDPOINT"] http_client = httpx.AsyncClient( auth=_ToolboxAuth(token_provider), # Microsoft Entra bearer token timeout=120.0, ) mcp_tool = MCPStreamableHTTPTool( name="toolbox", url=toolbox_endpoint, http_client=http_client, load_prompts=False, ) # Agent now has access to web search, AI Search, and GitHub MCP # through one tool definition and one authenticated connection. GitOps Workflow Extension for Toolboxes Add a dedicated job to your build-deploy workflow to create and promote toolbox versions as part of the same CI/CD pipeline: deploy-toolbox: name: Deploy Toolbox Version needs: validate runs-on: ubuntu-latest environment: dev permissions: id-token: write contents: read steps: - uses: actions/checkout@v4 - name: Azure login (OIDC) uses: azure/login@v3 with: client-id: ${{ secrets.AZURE_CLIENT_ID_DEV }} tenant-id: ${{ secrets.AZURE_TENANT_ID }} subscription-id: ${{ secrets.AZURE_SUBSCRIPTION_ID }} - name: Create toolbox version in Foundry env: FOUNDRY_PROJECT_ENDPOINT: ${{ vars.FOUNDRY_PROJECT_ENDPOINT_DEV }} BING_CONNECTION_NAME: ${{ vars.BING_CONNECTION_NAME }} BING_INSTANCE_NAME: ${{ vars.BING_INSTANCE_NAME }} SEARCH_INDEX_NAME: ${{ vars.SEARCH_INDEX_NAME }} SEARCH_CONNECTION_ID: ${{ vars.SEARCH_CONNECTION_ID }} GITHUB_CONNECTION_ID: ${{ vars.GITHUB_CONNECTION_ID }} run: python src/tools/toolbox_config.py Key points to note: Toolbox configuration is Python code in source control, reviewed through pull requests like any other change Connection IDs and index names are environment variables from GitHub Actions variables, not hardcoded in the script The same script runs for dev, test, and prod with different environment variable bindings Toolbox version promotion is a separate step from agent deployment, so you can update tools independently of the agent container Because the toolbox endpoint is stable, rolling back a toolbox version does not require rolling back the agent image Common Pitfalls Teams adopting this pattern commonly make the following mistakes. Identifying them early saves significant operational pain later. Treating prompts as unmanaged text. If your system prompt lives in a portal text box rather than a versioned file, you have no history, no review process, and no rollback capability. Move prompts into source control on day one. Deploying manually from the portal. Even one manual deployment breaks the GitOps contract. Your repository no longer reflects the true state of the environment. Automate everything and remove portal deployment permissions from individuals. Mixing environment configuration into source files. Hardcoded endpoint URLs or model deployment names in agent_config.json mean your dev and prod configurations diverge at the source level. Use parameter files and environment variables resolved at deployment time. Poor separation between agent logic and tool logic. When agents and tools are tightly coupled in a single file, a tool change requires a full agent review and redeployment. Keep them separate so they can evolve independently. Not versioning your Toolbox definition. Defining a Foundry Toolbox interactively through the portal gives you no audit trail and no rollback path. The toolbox configuration script belongs in source control alongside your agent code. Skipping evaluation before promotion. Deploying a prompt change without running a structured evaluation against a representative test set is how regressions reach production. Build evaluation into the pull request workflow, not just the deployment workflow. No rollback plan. If your first rollback is unplanned and urgent, it will be slow and stressful. Test your rollback procedure in a non-production environment and document the steps. Ignoring token and cost signals. AI workloads have variable cost profiles. A change that doubles average token consumption per request may be functionally correct but economically unsustainable. Monitor consumption as a first-class signal. Example GitHub Actions Workflow The following workflow runs on pull request validation and on merge to main. It covers the core delivery lifecycle: validate, build, deploy to dev, and smoke test. # .github/workflows/build-deploy.yml name: Build and Deploy Foundry Hosted Agent on: push: branches: - main pull_request: branches: - main env: REGISTRY: myregistry.azurecr.io IMAGE_NAME: my-foundry-agent jobs: validate: name: Validate Agent Configuration runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - name: Set up Python uses: actions/setup-python@v5 with: python-version: "3.12" - name: Install dependencies run: pip install -r requirements.txt - name: Validate agent config schema run: python scripts/validate_agent.py - name: Run unit tests run: pytest tests/unit/ -v - name: Lint code run: ruff check src/ build: name: Build and Push Container Image needs: validate runs-on: ubuntu-latest if: github.ref == 'refs/heads/main' permissions: id-token: write contents: read outputs: image_tag: ${{ steps.meta.outputs.version }} steps: - uses: actions/checkout@v4 - name: Azure login (OIDC) uses: azure/login@v3 with: client-id: ${{ secrets.AZURE_CLIENT_ID }} tenant-id: ${{ secrets.AZURE_TENANT_ID }} subscription-id: ${{ secrets.AZURE_SUBSCRIPTION_ID }} - name: Log in to Azure Container Registry run: az acr login --name ${{ env.REGISTRY }} - name: Extract metadata id: meta uses: docker/metadata-action@v5 with: images: ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }} tags: | type=sha,format=short - name: Build and push image uses: docker/build-push-action@v7 with: context: . push: true tags: ${{ steps.meta.outputs.tags }} deploy-dev: name: Deploy to Foundry Dev needs: build runs-on: ubuntu-latest environment: dev permissions: id-token: write contents: read steps: - uses: actions/checkout@v4 - name: Azure login (OIDC) uses: azure/login@v3 with: client-id: ${{ secrets.AZURE_CLIENT_ID_DEV }} tenant-id: ${{ secrets.AZURE_TENANT_ID }} subscription-id: ${{ secrets.AZURE_SUBSCRIPTION_ID }} - name: Deploy agent to Foundry Dev project run: | az ai foundry agent deploy \ --project ${{ vars.FOUNDRY_PROJECT_DEV }} \ --image ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:${{ needs.build.outputs.image_tag }} \ --environment dev - name: Run smoke tests against dev run: pytest tests/smoke/ -v --base-url ${{ vars.AGENT_URL_DEV }} deploy-test: name: Deploy to Foundry Test needs: deploy-dev runs-on: ubuntu-latest environment: test permissions: id-token: write contents: read steps: - uses: actions/checkout@v4 - name: Azure login (OIDC) uses: azure/login@v3 with: client-id: ${{ secrets.AZURE_CLIENT_ID_TEST }} tenant-id: ${{ secrets.AZURE_TENANT_ID }} subscription-id: ${{ secrets.AZURE_SUBSCRIPTION_ID }} - name: Deploy agent to Foundry Test project run: | az ai foundry agent deploy \ --project ${{ vars.FOUNDRY_PROJECT_TEST }} \ --image ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:${{ needs.build.outputs.image_tag }} \ --environment test - name: Run smoke tests against test run: pytest tests/smoke/ -v --base-url ${{ vars.AGENT_URL_TEST }} Key decisions in this workflow: Validation runs on every pull request, not just on merge. Fast feedback catches problems before review. The container image is built once and the image tag is passed forward to deployment jobs. The same artefact is promoted across environments. Authentication uses OIDC federated credentials via azure/login@v3 with id-token: write permissions. No long-lived secrets are stored in GitHub for Azure authentication. The environment: test directive in the deploy-test job triggers a GitHub environment approval gate. A named reviewer must approve before the job runs. Smoke tests run after every deployment. A failed smoke test prevents further promotion. Best Practices Checklist Use this checklist when adopting the GitOps pattern for a Microsoft Foundry Hosted Agent: All agent artefacts, including prompts, tool definitions, model configuration, and Toolbox configuration scripts, are committed to source control No manual deployments to any environment; all changes flow through GitHub Actions workflows Pull request reviews are enforced for all changes to agent logic, prompts, and infrastructure via CODEOWNERS Unit tests cover tool logic; integration tests cover end-to-end agent behaviour; smoke tests cover deployed environments Container images are built once per commit and promoted across environments; images are not rebuilt per environment Environment configuration (endpoints, resource names) lives in parameter files, never in source code Secrets are stored in Azure Key Vault and accessed via managed identity at runtime GitHub environment approval gates control promotion from dev to test to prod Foundry Toolboxes are used to centralise tool definitions, credentials, and access governance across all agents; the toolbox configuration script is version-controlled and deployed through CI/CD Toolbox versions are promoted via the update default_version API step in the deployment workflow, not manually through the portal Latency, error rate, and token consumption are monitored with alerting thresholds The rollback procedure is documented, automated, and has been tested in a non-production environment GitHub Issues are used to record the intent behind significant changes and link to the pull requests that implement them Branch protection rules prevent direct pushes to main and require status checks to pass before merge The previous image tag is retained in the registry and stored as a GitHub environment variable for rollback Conclusion A Microsoft Foundry Hosted Agent is not something you deploy once and forget. Prompts evolve, tools change, models are upgraded, and policy requirements shift. Every one of those changes has the potential to alter agent behaviour in ways that affect users, costs, and compliance posture. GitOps, implemented through GitHub and GitHub Tasks, gives you the operational discipline to manage that complexity. Source control for all artefacts. Pull request review for every change. Automated validation, build, and deployment. Environment promotion gates. A complete audit trail from task to production. These are not bureaucratic overhead; they are the foundation of reliable, trustworthy AI agent operations. The teams that operate AI agents well are the ones that treat them like production software from the start. The investment in pipeline, structure, and governance pays back every time a change goes smoothly, every time a rollback takes minutes rather than hours, and every time a security or compliance reviewer can answer their question from a pull request history rather than a support ticket. Build the discipline in early. Your future self, and your production environment, will benefit from it.

Enables enterprise-grade governance without changing your developer workflow. The official Microsoft Learn article (Configure Claude Code for Microsoft Foundry) gets you ~80% of the way there. The remaining 20%—VS Code settings shape, tenant mismatches, and configuration conflicts like "baseURL and resource are mutually exclusive"—is where most setups fail in practice. This guide walks the full path end-to-end, with the exact JSON that validates, working CLI configuration, and a troubleshooting matrix based on real-world failures. This guidance is based on repeated customer deployments and internal testing across both CLI and VS Code scenarios. TL;DR Setup - Deploy claude-sonnet-4-6 (optionally Haiku + Opus) in a supported region - Grant Cognitive Services User + Foundry User - az login --tenant <tenant> , then launch VS Code via code . Config - CLI: - CLAUDE_CODE_USE_FOUNDRY=1 - ANTHROPIC_FOUNDRY_RESOURCE=<name> - Do NOT set ANTHROPIC_FOUNDRY_BASE_URL at the same time - VS Code: - Use [{ "name": "...", "value": "..." }] format Validate - claude → /status - Expect: API provider: Microsoft Foundry Why run Claude Code on Foundry? Anthropic's Claude Code is a top-tier agentic coding assistant. Running it through Microsoft Foundry instead of Anthropic's public API gives you: Data residency & compliance: prompts and completions stay inside your Azure tenant. Entra ID auth: no API keys to rotate; centralized RBAC. Private networking: works behind VNets/Private Endpoints. Unified billing & quotas: usage shows up on your Azure invoice and in Foundry monitoring. Same model, same CLI, enterprise-grade plumbing underneath. Prerequisites checklist Requirement How to verify Azure subscription with pay-as-you-go billing az account show Foundry resource in supported regions Check your region's model availability in Foundry portal Contributor/Owner on the resource group (for deployments) Azure Portal → IAM Cognitive Services User + Foundry User on the resource (for invoking) Azure Portal → IAM Azure CLI installed and logged in az --version , az login Claude Code CLI installed claude --version VS Code (current) with the Anthropic Claude Code extension Help → About Windows only: Git Bash (from Git for Windows) or WSL2 — Claude Code's runtime requires a POSIX shell bash --version in Git Bash / WSL ⚠️ Claude models in Foundry are currently available in select regions. Check the Foundry portal model catalog for your region's availability (commonly East US 2 and Sweden Central). Step 1 — Deploy the Claude models Claude Code uses three model roles, and it expects a deployment for each: Role Default deployment name Used for Primary claude-sonnet-4-6 general coding (balanced) Fast claude-haiku-4-5 quick edits, file reads Extended thinking claude-opus-4-6 complex reasoning Deploy at least Sonnet to get started. Add Haiku and Opus when you need them — Claude Code will route automatically. If a role-specific model isn't deployed, Claude Code may fall back or fail depending on the task. Deployment names in this guide follow the current Claude 4.x naming exposed in Foundry. Exact versions change over time — check the Foundry model catalog in your region for what's currently available. Foundry Portal: AI Foundry → your project → Build → Models + endpoints → + Deploy model → pick the Anthropic Claude model → Global Standard deployment → name it exactly as above (or remember the name to override later). To discover the current model version before deploying (replace eastus2 with your Foundry region): az cognitiveservices model list -l eastus2 ` --query "[?contains(model.name,'claude')].{name:model.name, version:model.version, format:model.format}" -o table Azure CLI: az cognitiveservices account deployment create ` --name <foundry-resource> ` --resource-group <rg> ` --deployment-name claude-sonnet-4-6 ` --model-name claude-sonnet-4-6 ` --model-version <version> ` --model-format Anthropic ` --sku-name GlobalStandard ` --sku-capacity 1 ✍️ Figure 1: Foundry portal “Models + endpoints” showing the three Claude deployments. Step 2 — Grant yourself the right roles This is the #1 source of silent failures. You need both: Role Role ID Purpose Cognitive Services User a97b65f3-24c7-4388-baec-2e87135dc908 data-plane invocation Foundry User (formerly Azure AI User) 53ca6127-db72-4b80-b1b0-d745d6d5456d Foundry-native permissions $me = az ad signed-in-user show --query id -o tsv $scope = az cognitiveservices account show -n <foundry-resource> -g <rg> --query id -o tsv # Use role IDs — rename-proof (works whether the display name is "Azure AI User" or "Foundry User") az role assignment create --assignee $me --role a97b65f3-24c7-4388-baec-2e87135dc908 --scope $scope # Cognitive Services User az role assignment create --assignee $me --role 53ca6127-db72-4b80-b1b0-d745d6d5456d --scope $scope # Foundry User (formerly Azure AI User) The Foundry RBAC rename (Azure AI User → Foundry User) is rolling out; both role names map to the same role definition (same role ID), depending on tenant rollout state. Use whichever role name your tenant exposes — or use the role IDs above to avoid ambiguity. Step 3 — Install the Claude Code CLI Use the official installer from Anthropic (auto-updates in the background): irm https://claude.ai/install.ps1 | iex claude --version If claude isn't on PATH, restart your shell. The installer drops it under %USERPROFILE%\.local\bin . Step 4 — Sign in to the right tenant If your Foundry resource lives in a tenant different from your default, an az login to the wrong tenant produces the cryptic error: ValueError: Unable to get authority configuration for https://login.microsoftonline.com/<bad-guid>. Authority would typically be in a format of https://login.microsoftonline.com/your_tenant Fix: az login --tenant <foundry-tenant-guid> az account set --subscription <foundry-subscription-guid> az account show # confirm tenant & subscription 💡 You can list every tenant you have access to with: az account list --query "[].{name:name, tenantId:tenantId}" -o table Step 5 — Configure the CLI Set these in the same PowerShell session you'll launch claude from: $env:CLAUDE_CODE_USE_FOUNDRY = "1" $env:ANTHROPIC_FOUNDRY_RESOURCE = "<your-foundry-resource-name>" # Optional: only if your deployment names differ from the defaults $env:ANTHROPIC_DEFAULT_SONNET_MODEL = "claude-sonnet-4-6" $env:ANTHROPIC_DEFAULT_HAIKU_MODEL = "claude-haiku-4-5" $env:ANTHROPIC_DEFAULT_OPUS_MODEL = "claude-opus-4-6" To make them persistent: setx CLAUDE_CODE_USE_FOUNDRY 1 (and so on), then sign out and back in (or restart Explorer). GUI apps like VS Code launched from the Start menu only pick up new user-env vars after the user session refreshes — opening a fresh terminal isn't enough. 🚫 The "mutually exclusive" trap API Error: baseURL and resource are mutually exclusive You'll hit this if you set both ANTHROPIC_FOUNDRY_RESOURCE and ANTHROPIC_FOUNDRY_BASE_URL . Pick one: Most users → ANTHROPIC_FOUNDRY_RESOURCE=<name> (Claude Code builds the URL). Custom subdomain / private endpoint → use ANTHROPIC_FOUNDRY_BASE_URL instead. Step 6 — Verify the CLI claude > /status Expected output: API provider: Microsoft Foundry Microsoft Foundry base URL: https://<resource>.services.ai.azure.com/anthropic Microsoft Foundry resource: <resource> Model: Default (claude-sonnet-4-6) ✍️ Figure 2: /status output confirming API provider: Microsoft Foundry . If you instead see "Anthropic" or it prompts for an Anthropic login, CLAUDE_CODE_USE_FOUNDRY isn't being inherited — see troubleshooting below. Step 7 — Configure the VS Code extension Install Claude Code from the VS Code Marketplace (publisher: Anthropic). Open user settings.json ( Ctrl+Shift+P → Preferences: Open User Settings (JSON)) and add: "claudeCode.environmentVariables": [ { "name": "CLAUDE_CODE_USE_FOUNDRY", "value": "1" }, { "name": "ANTHROPIC_FOUNDRY_RESOURCE", "value": "<your-foundry-resource-name>" } ] 🪤 Schema gotcha. The MS Learn doc currently shows this as a plain {KEY: VALUE} object under the UI label "Claude Code: Environment Variables" . In recent extension versions the actual JSON key is claudeCode.environmentVariables and the value must be an array of {name, value} objects. If you paste the doc's snippet verbatim, VS Code will flag "Missing property name", "Colon expected", "Unknown configuration setting". Use the array form above. Make the extension see your az login The extension inherits environment & credentials from the process that launches VS Code. After az login : # In the same PowerShell where az login succeeded: code . If VS Code was already running, fully quit it (not just close the window) and relaunch from the terminal. Developer: Reload Window is not enough to refresh inherited Azure CLI credentials. ✍️ Figure 3: settings.json with the claudeCode.environmentVariables array form. Step 8 — Try it In VS Code, click the Claude Code (Spark) icon in the sidebar to open the panel. Type: Summarize the structure of this project. You should get a response within a few seconds, and the panel should indicate it's routing through Microsoft Foundry. Run /status inside the panel to confirm API provider: Microsoft Foundry if you want certainty. ✍️ Figure 4: Claude Code panel in VS Code responding through Microsoft Foundry.

If you must use a key for CI, store it as a secret (GitHub Actions secret, Key Vault) — never in settings.json (it may sync via Settings Sync). - Scope RBAC at the resource level, not the subscription, for least privilege. Project context - Create a CLAUDE.md at your repo root with stack, conventions, and entry-point commands. Claude Code reads it automatically and the quality jump is significant. - Use .claude/rules/*.md for per-area rules (e.g., test conventions, security rules). Cost & latency - Let Claude Code's auto-routing pick the right role (Sonnet/Haiku/Opus). Don't pin everything to Opus. - Cap context with ANTHROPIC_MAX_TOKENS if you have a strict budget. (Note: not honored by every Claude Code version — check the Claude Code docs for your version.) - Watch token spend in Foundry → Operate → Metrics weekly. Reliability - For team use, deploy all three model roles even if you don't think you need them — silent role-routing failures are confusing. - Tag your Foundry resource ( env=dev|prod , team=... ) for chargeback. Reproducibility - Document the exact env vars and az login --tenant GUID in your team README. - Pin Claude Code CLI version in onboarding docs ( claude --version ) so new joiners hit the same behavior. A note on the MS Learn doc The doc is accurate but skips three things that caused the most friction in real-world deployments: VS Code extension settings shape — the example uses the UI label as a JSON key and an object instead of the array form the schema actually expects. Process inheritance — it says "set the env vars" but doesn't emphasize that the VS Code window must be launched from a shell where both az login and the env vars are live. Reloading the window doesn't help. Mutually exclusive RESOURCE vs BASE_URL — listed in passing, but the error message only appears at first request, after you think everything is configured. If the Microsoft Learn page is updated, treat this post as a companion — same destination, fewer dead ends. What you've got now Claude Code running locally on your machine, talking to your Foundry resource. Entra ID auth — no API keys to manage. Full Foundry telemetry, quotas, and billing. VS Code panel + CLI, both backed by the same setup. Drop a CLAUDE.md in your repo and start shipping. When to Use RESOURCE vs BASE_URL Use RESOURCE (default) - Standard public deployments - No custom networking Use BASE_URL - Private endpoints - Custom DNS / VNet routing Never set both.From Requirement to Production Code, How Engineering Squad Automates the Full Dev Lifecycle
I started wondering: what if instead of one AI assistant generating code snippets, you had an entire squad of specialized AI agents. Each owning a single stage of the delivery pipeline, they could collaborate, self-correct, and produce a complete, traceable output from a plain-text requirement? That's Engineering Squad: an open-source, multi-agent framework built with LangGraph, Azure OpenAI, and Foundry Local. Nine agents. One pipeline. Zero manual handoffs. You give it a requirement. It gives you back: - User stories with acceptance criteria - Technical design (API contracts, data models, architecture) - Full implementation code (written into real files, not markdown) - Unit tests and Playwright E2E tests - Automated code review with a self-correcting feedback loop When the Code Reviewer finds a bug, it doesn't just flag it, it routes the work back to the exact agent that needs to fix it. When the Spec Agent hits ambiguity, it stops and asks you rather than guessing. The loop runs up to 5 iterations, and every run is versioned under a unique Run ID for full traceability. It runs on Azure OpenAI for heavy reasoning, Foundry Local for lightweight tasks or entirely offline with --local-only mode. No cloud required. How It Works The squad is a directed graph of 9 specialized agents. Each agent has a single responsibility and a tuned system prompt. The orchestration is handled by LangGraph's StateGraph, which routes work through the pipeline and handles feedback loops. The Agents Agent Model Responsibility Product Owner Azure OpenAI gpt-4.1 Reads requirements, classifies impact scope Story Agent Foundry Local (qwen2.5-7b) Converts requirements → structured user stories Spec Agent Azure OpenAI o3 Resolves ambiguity — asks the user interactively Technical Design Azure OpenAI gpt-4.1 Architecture, API contracts, data models, error handling Developer Azure OpenAI gpt-4.1 Writes code directly into the codebase Unit Tester Azure OpenAI gpt-4.1 Writes unit tests and evaluates them against implementation Test Writer Foundry Local (qwen2.5-7b) Writes Playwright E2E tests using Page Object Model Tester Azure OpenAI o3 Final evaluation of code against all specs and tests Code Reviewer Azure OpenAI o3 Reviews everything, decides: approve or route back The Self-Correcting Loop This is where it gets interesting. The Code Reviewer doesn't just say "approved" or "rejected" — it makes a routing decision using structured output: class ReviewDecision(BaseModel): decision: Literal[ "approved", # Ship it "requirement_confusion", # → Spec Agent (clarify ambiguity) "clarity_missing", # → Technical Design (refine design) "code_missing", # → Developer (fix implementation) "bug_found", # → Developer (fix bugs) "test_case_missing", # → Test Writer (add coverage) ] feedback: str # Actionable feedback for the target agent LangGraph's conditional edges route the workflow back to the exact agent that needs to act. The loop runs up to 5 iterations with a hard stop to prevent infinite cycles. workflow.add_conditional_edges( "code_reviewer", route_review, { END: END, "spec_agent": "spec_agent", "technical_design": "technical_design", "developer": "developer", "test_writer": "test_writer", }, ) Key Design Decisions 1. Impact Classification — Don't Run What You Don't Need Not every change needs the full pipeline. The squad classifies scope first: Scope What Runs config Impact Analysis → Developer → Unit Tester → Reviewer bugfix Impact Analysis → Developer → Unit Tester → Tester → Reviewer enhancement Stories → Design (if needed) → Developer → All Tests → Reviewer feature Stories → Design → Developer → All Tests → Reviewer refactor Impact Analysis → Developer → Unit Tester → Reviewer A config change doesn't need user stories. A bugfix doesn't need a full architectural design. This keeps runs fast and focused. 2. Code Goes Into Real Files, Not Markdown This was a deliberate choice. The Developer Agent edits actual source files in your project — it doesn't dump code into a markdown artifact. The code_changes.md artifact is a change log that records what was modified and why, for traceability. 3. Existing Projects vs. Greenfield Set PROJECT_TYPE: existing in requirements_input.txt, point it at your repos, and the squad will: Scan your codebase for patterns, conventions, and architecture Make targeted changes only — no rewriting from scratch Preserve your existing coding style, error handling, and naming conventions 4. Two LLM Tiers — Cloud + Local The framework uses a hybrid model strategy: Azure OpenAI (gpt-4.1, o3) for complex reasoning: code generation, technical design, code review Foundry Local (qwen2.5-7b, phi-3.5-mini) for lightweight tasks: user stories, test writing This keeps costs down while maintaining quality where it matters. And with --local-only mode, you can run the entire squad on Foundry Local with zero cloud dependencies. Running It Locally with Foundry Local One of my favorite features: the entire squad can run 100% locally using Foundry Local. No Azure subscription, no API keys, no internet required. Setup # Install Foundry Local CLI (one-time) winget install Microsoft.FoundryLocal # Install Python dependencies pip install foundry-local-sdk openai langchain-openai langgraph python-dotenv # Run in local-only mode python main.py --local-only When --local-only is set, every agent that would normally call Azure OpenAI gets redirected to Foundry Local: def get_azure_llm(deployment: str, temperature: float = 0.1): # Local-only mode: redirect to Foundry Local if os.getenv("SQUAD_LOCAL_ONLY", "").lower() in ("true", "1", "yes"): from models.local_llm import get_local_llm return get_local_llm(temperature=temperature) # Otherwise: use Azure OpenAI with DefaultAzureCredential ... The foundry-local-sdk (v1.1.0+) handles everything — initializing the runtime, downloading models, and loading them: from foundry_local_sdk import FoundryLocalManager, Configuration # Initialize once (singleton) config = Configuration(app_name="my-app") manager = FoundryLocalManager(config) # Start OpenAI-compatible web service manager.start_web_service() print(manager.urls[0]) # SDK auto-discovers the endpoint # Download & load a model model = manager.catalog.get_model("qwen2.5-7b") model.download() model.load() # Chat directly — no web service needed chat = model.get_chat_client() response = chat.complete_chat([{"role": "user", "content": "Hello!"}]) Jupyter Notebook The repo includes a Jupyter notebook (foundry_local.ipynb) that walks you through: Installing Foundry Local Loading a model Sending chat completions (streaming and non-streaming) Running the full Engineering Squad in local-only mode Traceability — Every Run Is Versioned Every squad execution gets a unique Run ID and produces a structured artifact set: output/ runs/ 20260524_a3f9b1/ run_metadata.json ← run ID, timestamp, requirement hash, decision impact_classification.md user_stories.md technical_design.md code_changes.md ← change log (code is in real files) unit_test_results.md tests.md test_results.md review_feedback.md latest/ ← symlink to most recent approved run The run_metadata.json is structured for future Azure DevOps integration — auto-creating work items, tasks, and test cases from squad output. Two Ways to Run Mode Best For GitHub Copilot Agent Mode Existing codebases — Copilot has full workspace context via #codebase Python CLI (python main.py) New projects, CI pipelines, fully automated runs Running with GitHub Copilot Agent Mode This is the recommended way to run the squad on existing projects. Copilot has full access to your workspace — it can read files, write code, and run terminal commands — so it naturally understands your architecture, patterns, and conventions. Prerequisites VS Code with the GitHub Copilot and GitHub Copilot Chat extensions installed A Copilot subscription that supports Agent Mode (Copilot Pro, Business, or Enterprise) Setup Clone the repo and open it in VS Code: git clone https://github.com/prasunagga/engineeringSquad.git code engineeringSquad Switch to Agent Mode — In the Copilot Chat panel, click the mode dropdown (top of the chat input) and select "Agent". This is required — Ask and Edit modes don't have tool access. Enable tools — Click the 🔧 tools icon (or gear/settings icon) at the bottom of the chat input area. Make sure the following tools are enabled: File operations (read, create, edit files) Terminal (run commands) Code search / workspace context Without these enabled, the squad can't read your codebase or write code into files. Edit your requirement — Open requirements_input.txt and write your requirement: PROJECT_TYPE: existing FRONTEND_PATH: plant-catalog BACKEND_PATH: Build a cart page where users can add plants, adjust quantities, and see totals. Running the Squad In Copilot Chat (Agent Mode), type: /run-squad This triggers the .github/prompts/run-squad.prompt.md file — a prompt file with mode: agent in its YAML frontmatter that orchestrates the full workflow: --- mode: agent description: Run the full Engineering Squad workflow tools: - read_file - create_file - replace_in_file - insert_text - delete_file_range --- Copilot will then execute the full pipeline: read requirements → classify impact → generate stories → design → write code → write tests → run tests → code review → approve or loop back. How It Differs from Python CLI Copilot Agent Mode Python CLI Context Full workspace awareness via #codebase Reads files from paths in requirements_input.txt Human-in-loop Spec Agent asks you directly in chat Spec Agent prints questions to stdout Code editing Uses VS Code's file editing tools Writes files via Python open() Test execution Runs npm test / playwright test in VS Code terminal Runs via subprocess Model Uses whichever model is selected in Copilot Uses Azure OpenAI / Foundry Local Individual Agent Prompts The .github/prompts/ directory also contains standalone prompt files for running individual agents: Prompt Purpose run-squad.prompt.md Full orchestrated pipeline developer.prompt.md Developer agent only code-reviewer.prompt.md Code review only story-agent.prompt.md Generate user stories only technical-design.prompt.md Technical design only test-writer.prompt.md Write E2E tests only Extending the Framework The squad is designed to be modular. Here are the most common extension points: Add a New Agent Every agent follows the same pattern — a function that takes SquadState, calls an LLM, and returns updated fields: # agents/my_agent.py from langchain_core.prompts import ChatPromptTemplate from graph.state import SquadState from models.azure_llm import get_azure_llm, DEPLOYMENT_DEVELOPER PROMPT = ChatPromptTemplate.from_messages([ ("system", "You are a security review specialist."), ("human", "Review this code for vulnerabilities:\n{code}"), ]) def my_agent_node(state: SquadState) -> dict: llm = get_azure_llm(deployment=DEPLOYMENT_DEVELOPER) result = (PROMPT | llm).invoke({"code": state["code"]}) return {"security_review": result.content} Then wire it in: Add state fields in graph/state.py Register the node and edges in graph/workflow.py Add artifact output in main.py Swap the LLM for Any Agent Each agent calls get_azure_llm(deployment=...) or get_local_llm(). You can: Change the model — edit .env (e.g., AZURE_DEPLOYMENT_DEVELOPER=gpt-5.4) Go fully local — python main.py --local-only Use a different provider — replace get_azure_llm() with any LangChain-compatible LLM (Anthropic, Ollama, Groq, etc.) Customize Agent Prompts Each agent's system prompt is defined as a ChatPromptTemplate at the top of its file in agents/. Edit the prompt directly — no configuration layer to navigate. Change the Review Loop The routing logic lives in graph/workflow.py → route_review(). Add new decision strings, change the routing map, or adjust MAX_ITERATIONS (default: 5). VS Code Copilot Agent Mode The .github/prompts/ directory contains prompt files for running individual agents in VS Code Copilot Agent Mode. Edit these to customize agent behavior when running through Copilot. What I Learned Building This Structured output is essential for routing. Without Pydantic models for review decisions, the conditional edge routing would be fragile and string-matching-dependent. Impact classification saves significant time. Running 9 agents for a one-line config change is wasteful. Classifying scope first makes the system practical. The self-correcting loop works — but needs a hard stop. Left unchecked, agents can ping-pong feedback indefinitely. The 5-iteration cap is a pragmatic safety net. Hybrid local + cloud models are the right balance. Not every task needs GPT-4.1. User story generation and test writing work well on smaller local models, cutting costs without sacrificing quality. "Ask, don't guess" is the single most important principle. When the Spec Agent encounters ambiguous requirements, it stops and asks the user rather than hallucinating assumptions. This one rule prevents the most costly category of errors. Try It Yourself The framework is open source and designed to be extensible: git clone https://github.com/prasunagga/engineeringSquad.git cd engineeringSquad pip install -r requirements.txt # Edit your requirement notepad requirements_input.txt # Run (local-only, no Azure needed) python main.py --local-only Requirements: Python 3.10+ Windows, macOS, or Linux For local-only: Foundry Local (winget install Microsoft.FoundryLocal) For cloud mode: Azure OpenAI endpoint + az login What's Next Azure DevOps MCP integration — Auto-sync stories, tasks, and test cases to ADO boards CI/CD trigger — Auto-run the squad on PR creation or work item assignment Multi-repo support — Frontend, backend, and infra in separate repositories Cost estimation — Estimate effort and cloud costs from the technical design Links GitHub: github.com/prasunagga/engineeringSquad Foundry Local docs: learn.microsoft.com/en-us/azure/foundry-local/what-is-foundry-local LangGraph docs: langchain.com/langgraph Azure OpenAI docs: azure.microsoft.com/en-us/products/ai-foundry/models/openaiWhat’s New in Microsoft 365 Copilot | May 2026
