64 TopicsIntroducing PII Shield: A Privacy Proxy for Every LLM Call
Why do we need a utility like PII Shield? Let’s start with an uncomfortable truth: modern AI systems are swimming in sensitive data - often without us fully realizing the risks we’re taking. The data is sensitive. Names, emails, phone numbers, credit cards, IBANs, SSNs, Aadhaar, PAN, Driving Licenses, UPI IDs, addresses - all of them frequently appear in user prompts, RAG documents, and tool inputs. Prompts leaving trust boundary: Even when the model lives in your own subscription - Azure OpenAI, a Foundry deployment, a self-hosted OSS model - the prompt still travels through SDKs, gateways, observability stacks etc. Before it gets to LLM, the inference layer often logs, evaluates, or fine-tunes against what it sees. Any of those hops could be a potential exposure of raw PII if not handled well. Changing regulatory asks: EU AI Act, India's DPDP Act, CCPA, HIPAA, PCI-DSS and a dozen sectoral rules now explicitly cover AI-driven processing. “Not knowing that your data may get stored elsewhere” is not an option anymore. The ad-hoc fixes don't scale. Most teams start with a regex or two. Then they add another team, another use case, another language, another ID format — and the regex file becomes a tar pit nobody wants to touch. The damage from getting this wrong is asymmetric. When controls hold and decisions are sound, nothing remarkable happens. The AI feature launches, threats are contained, and the system does what it was designed to do. But when security assumptions fail, the consequences compound fast. A single misstep can trigger public disclosures, regulatory scrutiny, financial penalties and more. That imbalance is why security can’t be treated as a finishing step. We need a single, well-tested, observable layer that sits between every AI application in the organisation and every model it talks to - and makes sure raw PII never crosses that boundary. Introducing PII Shield "PII Shield" is an intelligent anonymization layer that sits between your AI application and the LLM. It detects PII, applies a configurable privacy action per entity type, and - when you want it to - reverses the anonymization after the LLM has done its work. At a glance: REST API: /anonymize, /deanonymize and /apps - built with FastAPI. PII detection via Microsoft Presidio, with a pluggable NLP backend (spaCy, ONNX, Stanza, HuggingFace Transformers). Custom recognisers for India specific identifiers: Aadhaar, PAN, Driving Licence (all 36 states), PIN code, UPI ID, Indian phone numbers — plus 100+ Presidio defaults. Per-entity strategies: replace, hash (SHA-256), encrypt (PQC ML-KEM-768 + AES-256-GCM) or fake Multi-tenant: register applications via POST /apps, configure strategies per app, route via the X-App-Id header. Reversible by design: the "Anonymise → LLM → De-anonymise" sandwich pattern means the LLM only sees anonymized values (e.g. {{PERSON_1}} and {{EMAIL_ADDRESS_2}} etc.), never the real values. Library mode: pip install pii_shield and use the engine directly for batch jobs, no FastAPI required. Observability built in - Open Telemetry traces/metrics/logs, dual-backend (OTLP for local Grafana LGTM, Azure Monitor for production), pre-built Grafana dashboards Before we go deep into how this works, let's understand a few key concepts that this utility is centered around. Entities and recognisers An entity is a single, contiguous piece of PII that PII Shield treats as one unit of redaction - for example PERSON, EMAIL_ADDRESS, PHONE_NUMBER, CREDIT_CARD, IBAN_CODE, LOCATION, IN_AADHAAR, IN_PAN, IN_DRIVING_LICENSE, IN_UPI_ID. Each entity has: a type (the label above) that determines which placeholder format and which anonymisation strategy applies. a span in the original text - start and end character offsets - so the anonymiser can replace exactly the right slice without disturbing the surrounding text. a confidence score (0.0–1.0) reported by whichever recogniser found it, which the downstream code uses to drop low-quality hits or break ties between overlapping matches. a stable identity within the request - two occurrences of "Rahul Sharma" are the same entity instance, so they collapse to a single {{PERSON_1}} placeholder rather than {{PERSON_1}} and {{PERSON_2}}. That property is what makes coreference survive the round-trip through the LLM. A recogniser is the component that actually finds entities of a given type in text. PII Shield uses three recognizers, and they typically run together: NLP recognisers rely on the language model loaded by the Presidio Analyzer (spaCy / ONNX / Stanza / Transformers). They're the right tool for entities that have no fixed shape such as PERSON, LOCATION, ORGANIZATION, NRP where context and grammar matter more than format. E.g. "Rahul met Priya in Bengaluru" can't be detected with regex; the model must understand that those tokens are people and a place. Pattern recognisers (extension of the PatternRecognizer Class) are small Python classes that combine three things: one or more regex patterns (e.g. the 12-digit Aadhaar layout, the AAAAA9999A PAN structure, a state-prefixed Driving Licence number); a list of context keywords that boost confidence when they appear nearby (aadhaar, uidai, licence, dl, pan, card, dob); and a base confidence score plus an optional validator function for IDs with a checksum (Aadhaar's Verhoeff digit, PAN's structural rules, IBAN's mod-97). The regex says "this could be an Aadhaar"; the context boost says "and the word 'aadhaar' is three tokens to the left, so I'm now very sure" and the validator says "the checksum agrees, accept it." That layering is what keeps false positives in check on noisy CRM notes and chat transcripts. Hybrid / deny-list recognisers sit on top, for things like an internal project codename list or a customer-id format that's specific to your business. When the Analyzer runs, every recogniser scores the same span independently; overlapping hits are reconciled (highest-confidence wins, longer spans absorb shorter ones), and a final list of (entity type, start, end, score) tuples is what the anonymiser sees. Adding a new recognizer is easy with the YAML configuration approach. Refer to the below document for details how-to-add-a-recognizer The Sandwich Pattern We call it a sandwich pattern because two thin layers of PII Shield wrap around the LLM call: a) the top slice (anonymise) replaces every detected entity with a stable, opaque placeholder before the prompt ever leaves your trust boundary, b) the bottom slice (de-anonymise) puts the original values back when the response returns. The LLM in the middle is just the filling - it reasons over {{PERSON_1}} and {{EMAIL_ADDRESS_2}} instead of "Rahul Sharma" and "rahul@example.com", and it has no idea that anything was ever swapped. This is what makes the pattern so easy to retrofit: your application keeps its existing prompts, the LLM keeps its existing API, and the only "PII Shield" component that knows the real values is the very short-lived mapping. Coreference still works end-to-end because {{PERSON_1}} is the same person everywhere in the prompt - and, almost always, everywhere in the response too. Encrypted entities use ML-KEM-768 + AES-256-GCM by default — a NIST-standardised post-quantum KEM. High level design The diagram below depicts key components of “PII Shield”. User / Client App: The end user (or a downstream service) who initiates the request that eventually reaches an AI workload. They are unaware of the redaction layer; from their perspective the AI app responds with full, restored PII. AI Application (Agent / RAG / Chat): The customer's GenAI workload (chatbot, agentic flow, RAG pipeline). It owns the business logic but does not call the LLM directly with raw user data. Instead, it routes every prompt through PII Shield first and only forwards the anonymized result. This keeps the AI app free of redaction logic and lets the same shield be reused across multiple workloads. PII Shield (FastAPI): The central, stateless service. Every request flows through this single boundary, which makes it the natural place to enforce policy, rate-limit, audit, and instrument. Internally it is composed of several cooperating layers: REST API - the public surface: POST /anonymize_unique (detect + redact in one call, returning a session ID), POST /deanonymize (restore using that session ID), plus /apps and /apps/{id}/config for tenant onboarding and per-app strategy configuration. Health, metrics, and OpenAPI docs are exposed alongside. Presidio Engine: the detection-and-redaction core, built on Microsoft Presidio and split into two stages - Analyze: runs the configured NLP backend (spaCy for fastest CPU inference, ONNX for quantized speed, Stanza for higher recall, or Hugging Face Transformers for state-of-the-art models like IndicNER) and PII Shield's own custom recognizers (Aadhaar, PAN, IFSC, UPI, IN_BANK_ACCOUNT, IN_PHONE, IN_PIN_CODE, CKYC, PRAN, APAAR, GeoCoordinate, NaturalDate, etc.). Each detected span carries a confidence score and is disambiguated using context-keyword boosting. Anonymizer (Operators): applies the per-entity strategy chosen by the app config: replace (placeholder tokens like {{IN_AADHAAR_1}} for the LLM-sandwich pattern), hash (irreversible SHA-256, for analytics on hashed values), encrypt (reversible AES-GCM or post-quantum Kyber for compliance-sensitive flows), or fake (format-preserving synthetic values from Faker for safe demo / synthetic-test datasets). State Stores: there are two logical stores, both backed by Redis but with different lifetimes and access patterns: Session Mapping Store: short-lived UUID→entity-map records that power the sandwich pattern (anonymize → call LLM → de-anonymize the response back to original values). The default TTL is intentionally short (seconds-to-minutes) so plaintext mappings don't linger. App Registry: long-lived per-app configuration: entity-type strategies, allow-lists, entity-type-allow-lists, encryption-key references, and a curated allow-list of fictional brand names. This is what makes the platform multi-tenant with per-tenant policy. Telemetry: Uses OpenTelemetry SDK, and auto-instruments every stage of the pipeline: span per request, metrics for entity-type counts/anonymization latency/cache hit rate, and structured logs with trace correlation. The same OTLP stream can be split between Azure Monitor and a self-hosted Grafana stack. LLM (Azure OpenAI / OSS): The downstream model. PII Shield's contract guarantees it only ever receives anonymized text; raw PII never crosses the trust boundary into the model provider's tenancy. This satisfies most data-residency, DPDP, and GDPR concerns by construction rather than by audit after the fact. Azure Monitor / OTLP → Grafana: This is where OpenTelemetry data lands. Operators get pre-built Grafana dashboards (request volume by entity type, p95/p99 latency per stage, per-app usage, error breakdowns) so production issues — a misbehaving recognizer, a slow NLP backend, a noisy app — are diagnosed from a single pane. Playground & Admin UI: Two Streamlit front-ends come bundled with the platform. The Playground lets developers paste arbitrary text, switch NLP backends, and instantly see what gets detected and how it is redacted — invaluable for tuning recognizers and demos. The Admin UI lets operators register applications, set per-entity strategies, manage allow-lists, and view live entity stats. Both call the same REST API, so anything the UI does is reproducible from a script or CI pipeline. Request flow at a glance - A user types a message into the AI application — say, a chatbot that helps customers with banking queries. Before the application sends anything to the language model, it hands the raw text over to PII Shield through the /anonymize_unique endpoint. PII Shield runs the text through its detection pipeline, swaps every piece of personal information for a stable placeholder token, and returns two things to the AI app: the redacted text and a short-lived session ID. The application then calls the LLM with this safe, placeholder-laden prompt — the model never sees a real Aadhaar number, account number, or phone number. Once the LLM responds, the AI app posts that response back to PII Shield's /deanonymize endpoint along with the same session ID it received earlier. PII Shield looks up the session, restores every placeholder in the LLM's reply with the original value, and hands the fully restored text back to the application, which delivers it to the user. From the user's perspective the conversation feels completely natural — they see their own details, in their own words, exactly as they'd expect. Behind the scenes, the session mapping that made the round-trip possible is automatically dropped from Redis the moment its TTL expires, so plaintext PII never lingers in the system longer than it has to. In parallel, every stage of this flow emits OpenTelemetry traces, metrics, and logs to the observability stack, giving operators a clear, real-time view of what was detected, how long each step took, and how the system is behaving in production. The entire set-up could be deployed on premises as well as on any of the clouds by replacing components with corresponding cloud offerings. Below is an example in Azure - Container apps is used to host the REST services, Azure Cache for Redis is for the state store, Application Insights, Log Ananlutics and Azure Managed Grafana are used for telemetry. Please refer to the codebase here for the implementation and deployment scripts (local & Azure). code repository pii-shield How does it work? The sandwich pattern explained earlier has three phrases: Anonymize LLM Processing De-anonymize Anonymize When the app sends POST /anonymize with "Call Rahul Sharma at rahul@example.com about Aadhaar 2345 6789 0123.", PII Shield does five things in order: Resolve config. If an X-App-Id header is present, the app's per-entity strategy map is loaded from Redis (with a short in-process cache to keep the hot path fast). If absent, global defaults apply. Detect. The Presidio Analyzer runs the configured NLP backend (spaCy / ONNX / Transformers) plus all built-in and custom pattern recognisers. The output is a list of spans — (entity_type, start, end, score, text) tuples — possibly overlapping, possibly with low-confidence noise. Post-analyse. Adjacent locations and PIN codes get merged into a single ADDRESS, overlapping detections are deduped (longest wins, ties broken by score), context keywords boost confidence, and entries below threshold are dropped. This is the difference between "raw Presidio output" and "something safe to anonymise". Assign unique placeholders. For each distinct PII value, a numbered placeholder is minted: {{PERSON_1}}, {{PERSON_2}}, … The numbering is per entity type, per request, and ordering is stable — the same person mentioned three times in the input gets the same {{PERSON_1}} everywhere. This is what lets the LLM reason about coreference correctly. Apply operators. For each entity, the per-app strategy decides what to write into the output: replace → the placeholder above (reversible; mapping kept). hash → {ENTITY}_<sha256-prefix>> (one-way; not added to entity_mapping — there's nothing to restore). encrypt → {{{ENTITY}_ENC_<base64-ciphertext>}} using ML-KEM-768 + AES-256-GCM (reversible without keeping a mapping; the ciphertext is self-contained). fake → a synthetic value from the locale-aware faker (irreversible; useful for demos and synthetic test data). The reversible mapping {placeholder → original} is then saved to the session store (in-memory dict keyed by a fresh UUID by default; swappable for Redis or a database). The response carries the id, the anonymized_text, and entity_mapping for inspection: { "id": "a1b2c3d4-...", "anonymized_text": "Call {{PERSON_1}} at {{EMAIL_ADDRESS_1}} about Aadhaar {{IN_AADHAAR_1}}.", "entity_mapping": { "{{PERSON_1}}": "Rahul Sharma", "{{EMAIL_ADDRESS_1}}": "rahul@example.com", "{{IN_AADHAAR_1}}": "2345 6789 0123" } } LLM Processing The app sends the anonymised text to the LLM exactly as it would have sent the original. The model treats {{PERSON_1}}, {{IN_AADHAAR_1}}, etc. as opaque proper nouns and reasons over them naturally. Because each distinct value got a stable, unique placeholder, the model doesn't lose coreference: "Tell {{PERSON_1}} that their Aadhaar {{IN_AADHAAR_1}} has been verified" still makes perfect sense. The response usually preserves the placeholders verbatim — sometimes the LLM rewrites half the sentence, but as long as the placeholders are still in there somewhere, de-anonymisation will work. De-anonymize The app calls POST /deanonymize with the session id and the LLM's response. PII Shield does three things: Fetch the mapping for that id from the session store (single dict lookup; sub-microsecond). Replace placeholders in the text — longest placeholder first. This matters: a naïve replacement could let {{PERSON_1}} clobber the inner part of {{PERSON_10}}. Sorting by length descending is a small detail with big consequences. Decrypt encrypted entities in-place. Encrypted entities don't appear in the session mapping (the ciphertext is the placeholder), so they're handled separately: any {{ENTITY_ENC_…}} token in the text is base64-decoded and decrypted with the configured backend (PQC by default; Fernet auto-detected for backwards compatibility). Importantly, the input text to /deanonymize does not have to match what /anonymize produced. The LLM may have rewritten everything around the placeholders - added text, translated, summarised - and PII Shield will still cleanly restore the PII wherever the placeholders appear. Only the placeholders trigger replacement; everything else passes through untouched. The library mode The application can also be used as a library if you do not want to deploy it as a service for batch use cases. Here is an example: from pii_shield import PiiShieldEngine engine = PiiShieldEngine() # load NLP model once, reuse result = engine.anonymize("Rahul's Aadhaar is 2345 6789 0123") # "<PERSON_1>'s Aadhaar is <IN_AADHAAR_1>" restored = engine.deanonymize(result.anonymized_text, result.entity_mapping) The BatchProcessor currently handles CSVs and DataFrames with thread/process parallelism - useful for ad-hoc file processing and batch offline pipelines. What's next PII Shield is the foundation. Where it really starts to pay off is when you wire it into the rest of your AI stack so that no developer can accidentally bypass it. There are two more blogs in the series: PII Shield as middleware in Microsoft Agent Framework Agents are versatile. They invoke tools, fan out to sub-agents, cache intermediate context, and call LLMs from places you didn't expect. The next post will show how to plug PII Shield in as a middleware in Microsoft Agent Framework — automatically anonymising every prompt going out to a model and de-anonymising every response coming back, transparently to the agent author. No more "did we remember to scrub this one?". PII Shield + Azure API Management (APIM) For organisations standardising on APIM as their LLM gateway, the natural place for PII Shield is inside the policy pipeline. The follow-up post will cover integrating PII Shield with APIM so that every request to an LLM backend — regardless of which app or team made it — is intercepted, anonymised, forwarded, and de-anonymised on the way back. One policy, organisation-wide privacy.From Test Cases to Trusted Automation: Scaling Enterprise Quality with GitHub Copilot
Automation First, But Trust Is Earned Enterprise QA teams today are automation‑led by default. Regression suites run daily, API tests validate integrations, and UI automation protects critical workflows. Yet, many teams still struggle with: Automation suites that lag behind changing requirements Brittle regression tests producing false failures High effort spent on maintaining, refactoring, and rewriting tests Limited time for testers to think deeply about risk and coverage Automation creates speed—but trust is built only when automation stays relevant, maintainable, and aligned to business intent. That is where AI‑assisted workflows started to play a role—not to replace automation engineers, but to remove friction from automation execution and evolution. GitHub Copilot as an Automation Accelerator GitHub Copilot proved most effective when used as a support system for automation teams, not a replacement for expertise. Faster Automation Creation Without Losing Intent Automation engineers often spend significant time writing boilerplate code—test scaffolding, assertions, setup, and repetitive patterns. Copilot helped accelerate this phase by: Generating consistent test skeletons Assisting with repetitive automation logic Suggesting assertions aligned to test intent This allowed engineers to focus on what needed to be validated, not how fast they could type it. Improving Maintainability of Automation Suites At enterprise scale, the true cost of automation is maintenance. Copilot helped reduce this burden by: Accelerating refactoring of existing test code Making automation scripts more readable and standardized Supporting quicker updates when requirements changed As a result, regression suites stayed healthier and more reliable—directly improving release confidence. Strengthening Regression Confidence Automation is valuable only when it can be trusted during regression cycles. By reducing effort spent on maintaining and updating tests, Copilot indirectly strengthened regression stability, ensuring automation remained aligned with evolving functionality. Importantly, every AI suggestion was reviewed, validated, and owned by humans. Automation logic remained intentional, deterministic, and compliant with enterprise standards. Automation at Scale: Where Quality Is Really Won or Lost As automation grows across releases and teams, quality risks move upstream. The questions stop being: Do we have automation? And become: Can we trust what automation is telling us? This is where quality engineering truly matters. By using Copilot to lower the mechanical overhead of automation, QA engineers could invest more time in: Identifying risk‑based test coverage gaps Improving negative and edge‑case scenarios Ensuring UI, API, and integration automation complemented each other Designing automation that reflected real business flows Automation stopped being a maintenance burden and became a strategic quality asset. The Real Mindset Shift for QA Teams The biggest impact was not technical—it was cultural. Instead of spending the majority of time creating and fixing automation scripts, QA engineers could shift their focus toward: Test design strategy Regression optimization Failure analysis and pattern recognition Cross‑team conversations on quality risks AI didn’t reduce QA effort. It redirected effort to higher‑value quality ownership. This is what modern QA leadership looks like—not writing more tests, but ensuring the right tests exist, run reliably, and protect customer trust. Responsible AI Was Non‑Negotiable In an enterprise context, automation quality is inseparable from governance and responsibility. Clear guardrails were essential: No blind acceptance of AI‑generated automation Human review for every test case and assertion Awareness of security, data sensitivity, and compliance Using Copilot as an assistant—not an authority This ensured automation quality improved without compromising trust or control. Final Thoughts: Automation Builds Speed, Trust Builds Confidence Automation enables scale. Test design ensures coverage. Trust is built when both evolve together. GitHub Copilot did not replace automation skills on our enterprise project—it amplified them. By removing friction from test creation and maintenance, it allowed automation to scale responsibly and enabled QA teams to focus on what truly matters: confidence in every release. The future of quality engineering is not manual vs automation. It is automation‑led, AI‑assisted, and human‑governed quality. That is how trust is built at enterprise scale.

The Traditional QA Bottleneck In complex enterprise systems, QA teams often face familiar challenges: Time‑consuming test case creation from evolving requirements Repetitive automation scripting and refactoring Heavy regression cycles under tight release timelines Limited bandwidth for deeper risk analysis and exploratory testing None of these issues are caused by lack of skill—they’re symptoms of scale and complexity. This is where GitHub Copilot entered our workflow—not as a “magic button,” but as a thinking partner. Where GitHub Copilot Actually Helped Used responsibly, Copilot added value in very specific QA scenarios: Faster Test Design from Requirements Transforming business or technical requirements into structured test scenarios is intellectually demanding but time-intensive. Copilot helped accelerate: Initial test scenario drafting Gherkin-style acceptance criteria Coverage identification for edge and negative cases The result wasn’t “auto-generated tests,” but faster starting points, reviewed and refined by humans. Accelerating Automation Without Losing Control Whether working with UI automation or API tests, a significant portion of effort goes into boilerplate code, assertions, and structuring. Copilot assisted with: Suggesting test skeletons Refactoring repetitive code Improving readability and consistency This freed engineers to focus on test intent, not syntax. Supporting Debugging and Maintenance Automation maintenance is often underestimated. Copilot helped: Identify potential fixes during test failures Suggest improvements during refactoring Reduce turnaround time during regression cycles Again, nothing was auto‑merged. Human review remained non‑negotiable. The Most Important Shift: QA Mindset The real impact of Copilot wasn’t just efficiency—it changed how QA engineers spent their time. Instead of: Writing repetitive scripts Manually expanding similar test cases The team could focus more on: Risk‑based testing Failure pattern analysis Cross‑team quality discussions Improving test strategy and coverage depth In short, AI didn’t remove QA effort—it redirected it to higher‑value work. Responsible AI Was Not Optional In an enterprise setup, responsible AI usage matters. Key principles we followed: No blind acceptance of AI suggestions Strict human validation of all test logic Awareness of data sensitivity and compliance boundaries Treating Copilot as an assistant, not an authority This balance ensured quality and trust were never compromised in the pursuit of speed. What This Means for QA Teams From this experience, one thing became clear: AI won’t replace QA engineers. But QA engineers who use AI effectively will redefine quality. GitHub Copilot helped shift QA from execution to enablement—from writing tests faster to thinking about quality better. For enterprise teams, this is a powerful evolution. Final Thoughts Quality engineering is no longer just about finding defects—it’s about enabling confidence in delivery. Tools like GitHub Copilot, when used responsibly, can become catalysts in that transformation. The future of QA isn’t manual vs automation. It’s human judgment amplified by AI assistance. And that’s where real quality lives. References Create and manage manual test cases - Azure Test Plans | Microsoft Learn What is Azure Test Plans?

Introduction The rise of AI-powered development is no longer just about autocomplete—it’s about autonomous agents that can think, act, and collaborate. At the center of this transformation is the Agent Client Protocol (ACP) and its integration with GitHub Copilot CLI. If you’ve ever wanted to: Integrate Copilot into your own tools Build custom AI-driven developer workflows Orchestrate coding agents in CI/CD Then understanding the GitHub Copilot CLI ACP Server is a game-changer. This article will take you from zero to advanced, covering concepts, architecture, setup, and real-world use cases. What Is Agent Client Protocol (ACP)? The Agent Client Protocol (ACP) is an open standard designed to connect clients (like IDEs or tools) with AI agents in a consistent and interoperable way. Why ACP Exists Before ACP: Every IDE needed custom integration for each AI agent Every agent needed custom APIs per editor ACP solves this by introducing a universal communication layer. Key Idea “Any editor can talk to any agent.” Core Capabilities ACP enables: Standardized messaging between client and agent Streaming responses Tool execution with permissions Session lifecycle management Multi-agent coordination This makes ACP a foundation layer for the agentic developer ecosystem. What Is GitHub Copilot CLI ACP Server? GitHub Copilot CLI can run as an ACP-compatible server, exposing its AI capabilities programmatically. 👉 In simple terms: It turns Copilot into a backend AI agent service that any tool can connect to. According to GitHub Docs: Copilot CLI can run in ACP mode using a flag It supports standardized communication via ACP It enables integration with IDEs, pipelines, and custom tools Architecture: How ACP + Copilot CLI Works Components Component Role Client Sends prompts, receives responses ACP Protocol Standard communication layer Copilot CLI AI agent executing tasks System Files, repos, tools Getting Started (Beginner Level) Install GitHub Copilot CLI Ensure: Copilot subscription is active CLI installed and authenticated Start ACP Server Default (stdio mode – recommended) TCP Mode (for remote systems) stdio: Best for IDE integration TCP: Best for distributed systems Connect Using ACP Client (Example) Using TypeScript SDK: You: Start Copilot as a process Create streams Initialize connection Send prompt Receive streaming response ACP uses: NDJSON streams over stdin/stdout Event-driven communication ACP Workflow Explained A typical flow looks like this: Step-by-step lifecycle Initialize connection Create session Send prompt Agent processes task Streaming updates returned Optional tool execution (with permissions) Session ends ACP supports: Text + multimodal inputs Incremental responses Cancellation and control Real-World Use Cases IDE Integration (Custom Editors) Build your own AI-powered editor: Connect via ACP Send code context Receive suggestions CI/CD Automation Imagine: Use ACP to: Auto-fix bugs Generate tests Refactor code Multi-Agent Systems ACP enables: Copilot + other agents working together Task delegation Workflow orchestration Custom Developer Tools Examples: AI code review dashboards Internal dev assistants ChatOps integrations Advanced Concepts Session Management ACP allows: Isolated sessions Custom working directories Context persistence Streaming Responses Instead of waiting: Receive responses in chunks Build real-time UIs Permission Handling ACP includes: Tool execution approvals Security boundaries Controlled automation Extensibility ACP supports: Multiple SDKs (TypeScript, Python, Rust, Kotlin) Custom clients Future protocol evolution ACP vs Traditional Integration Feature Traditional APIs ACP Integration Custom per tool Standardized Streaming Limited Native Multi-agent Hard Built-in Extensibility Low High Interoperability Poor Excellent Why ACP + Copilot CLI Is a Big Deal This combination unlocks: ✅ Platform-level AI integration No more vendor lock-in per editor ✅ True agentic workflows Agents don’t just suggest—they act ✅ Ecosystem growth Any tool can plug into Copilot Challenges & Considerations ACP is still in public preview Requires understanding of: Streams Async communication Debugging agent workflows can be complex Future of Developer Experience ACP represents a shift toward: “AI-native development platforms” Future possibilities: Fully autonomous CI/CD pipelines Cross-agent collaboration Self-healing codebases Final Thoughts The GitHub Copilot CLI ACP Server is not just a feature—it’s a foundation for the next generation of software development. If you are: A developer → build smarter tools A tech lead → design AI-driven workflows A CTO aspirant → understand this deeply Then ACP is something you must master early. Quick Summary ACP = Standard protocol for AI agents Copilot CLI = Can run as ACP server Enables = IDEs, CI/CD, multi-agent systems Key power = interoperability + automationThe Future of Agentic AI: Inside Microsoft Agent Framework 1.0
Agentic AI is rapidly moving beyond demos and chatbots toward long‑running, autonomous systems that reason, call tools, collaborate with other agents, and operate reliably in production. On April 3, 2026, Microsoft marked a major milestone with the General Availability (GA) release of Microsoft Agent Framework 1.0, a production‑ready, open‑source framework for building agents and multi‑agent workflows in.NET and Python. [techcommun...rosoft.com] In this post, we’ll deep‑dive into: What Microsoft Agent Framework actually is Its core architecture and design principles What’s new in version 1.0 How it differs from other agent frameworks When and how to use it—with real code examples What Is Microsoft Agent Framework? According to the official announcement, Microsoft Agent Framework is an open‑source SDK and runtime for building AI agents and multi‑agent workflows with strong enterprise foundations. Agent Framework provides two primary capability categories: 1. Agents Agents are long‑lived runtime components that: Use LLMs to interpret inputs Call tools and MCP servers Maintain session state Generate responses They are not just prompt wrappers, but stateful execution units. 2. Workflows Workflows are graph‑based orchestration engines that: Connect agents and functions Enforce execution order Support checkpointing and human‑in‑the‑loop scenarios This leads to a clean separation of responsibilities: Concern Handled By Reasoning & interpretation Agent Execution policy & control flow Workflow This separation is a foundational design decision. High‑Level Architecture From the official overview, Agent Framework is composed of several core building blocks: Model clients (chat completions & responses) Agent sessions (state & conversation management) Context providers (memory and retrieval) Middleware pipeline (interception, filtering, telemetry) MCP clients (tool discovery and invocation) Workflow engine (graph‑based orchestration) Conceptual Flow 🌟 What’s New in Version 1.0 Version 1.0 marks the transition from "Release Candidate" to "General Availability" (GA). Production-Ready Stability: Unlike the earlier experimental packages, 1.0 offers stable APIs, versioned releases, and a commitment to long-term support (LTS). A2A Protocol (Agent-to-Agent): A new structured messaging protocol that allows agents to communicate across different runtimes. For example, an agent built in Python can seamlessly coordinate with an agent running in a .NET environment. MCP (Model Context Protocol) Support: Full integration with the Model Context Protocol, enabling agents to dynamically discover and invoke external tools and data sources without manual integration code. Multi-Agent Orchestration Patterns: Stable implementations of complex patterns, including: Sequential: Linear handoffs between specialized agents. Group Chat: Collaborative reasoning where agents discuss and solve problems. Magentic-One: A sophisticated pattern for task-oriented reasoning and planning. Middleware Pipeline: The new middleware architecture lets you inject logic into the agent's execution loop without modifying the core prompts. This is essential for Responsible AI (RAI), allowing you to add content safety filters, logging, and compliance checks globally.

Let me be direct: there's a lot of noise in the conference calendar. Generic cloud events. Vendor showcases dressed up as technical content. Sessions that look great on paper but leave you with nothing you can actually ship on Monday. ECS 2026 isn't that. As someone who will be on stage at Cologne this May, I can tell you the European Collaboration Summit combined with the European AI & Cloud Summit and European Biz Apps Summit is one of the few events I've seen where engineers leave with real, production-applicable knowledge. Three days. Three summits. 3,000+ attendees. One of the largest Microsoft-focused events in Europe, and it keeps getting better. If you're building AI systems on Azure, designing cloud-native architectures, or trying to figure out how to take your AI experiments to production — this is where the conversation is happening. What ECS 2026 Actually Is ECS 2026 runs May 5–7 at Confex in Cologne, Germany. It brings together three co-located summits under one roof: European Collaboration Summit — Microsoft 365, Teams, Copilot, and governance European AI & Cloud Summit — Azure architecture, AI agents, cloud security, responsible AI European BizApps Summit — Power Platform, Microsoft Fabric, Dynamics For Azure engineers and AI developers, the European AI & Cloud Summit is your primary destination. But don't ignore the overlap, some of the most interesting AI conversations happen at the intersection of collaboration tooling and cloud infrastructure. The scale matters here: 3,000+ attendees, 100+ sessions, multiple deep-dive tracks, and a speaker lineup that includes Microsoft executives, Regional Directors, and MVPs who have built, broken, and rebuilt production systems. The Azure + AI Track - What's Actually On the Agenda The AI & Cloud Summit agenda is built around real technical depth. Not "intro to AI" content, actual architecture decisions, patterns that work, and lessons from things that didn't. Here's what you can expect: AI Agents and Agentic Systems This is where the energy is right now, and ECS is leaning in. Expect sessions covering how to design agent workflows, chain reasoning steps, handle memory and state, and integrate with Azure AI services. Marco Casalaina, VP of Products for Azure AI at Microsoft, is speaking if you want to understand the direction of the Azure AI platform from the people building it, this is a direct line. Azure Architecture at Scale Cloud-native patterns, microservices, containers, and the architectural decisions that determine whether your system holds up under real load. These sessions go beyond theory you'll hear from engineers who've shipped these designs at enterprise scale. Observability, DevOps, and Production AI Getting AI to production is harder than the demos suggest. Sessions here cover monitoring AI systems, integrating LLMs into CI/CD pipelines, and building the operational practices that keep AI in production reliable and governable. Cloud Security and Compliance Security isn't optional when you're putting AI in front of users or connecting it to enterprise data. Tracks cover identity, access patterns, responsible AI governance, and how to design systems that satisfy compliance requirements without becoming unmaintainable. Pre-Conference Deep Dives One underrated part of ECS: the pre-conference workshops. These are extended, hands-on sessions typically 3–6 hours that let you go deep on a single topic with an expert. Think of them as intensive short courses where you can actually work through the material, not just watch slides. If you're newer to a particular area of Azure AI, or you want to build fluency in a specific pattern before the main conference sessions, these are worth the early travel. The Speaker Quality Is Different Here The ECS speaker roster includes Microsoft executives, Microsoft MVPs, and Regional Directors, people who have real accountability for the products and patterns they're presenting. You'll hear from over 20 Microsoft speakers: Marco Casalaina — VP of Products, Azure AI at Microsoft Adam Harmetz — VP of Product at Microsoft, Enterprise Agent And dozens of MVPs and Regional Directors who are in the field every day, solving the same problems you are. These aren't keynote-only speakers — they're in the session rooms, at the hallway track, available for real conversations. The Hallway Track Is Not a Cliché I know "networking" sounds like a corporate afterthought. At ECS it genuinely isn't. When you put 3,000 practitioners, engineers, architects, DevOps leads, security specialists in one venue for three days, the conversations between sessions are often more valuable than the sessions themselves. You get candid answers to "how are you actually handling X in production?" that you won't find in documentation. The European Microsoft community is tight-knit and collaborative. ECS is where that community concentrates. Why This Matters Right Now We're in a period where AI development is moving fast but the engineering discipline around it is still maturing. Most teams are figuring out: How to move from AI prototype to production system How to instrument and observe AI behaviour reliably How to design agent systems that don't become unmaintainable How to satisfy security and compliance requirements in AI-integrated architectures ECS 2026 is one of the few places where you can get direct answers to these questions from people who've solved them — not theoretically, but in production, on Azure, in the last 12 months. If you go, you'll come back with practical patterns you can apply immediately. That's the bar I hold events to. ECS consistently clears it.

And if you're coming, find me, I'll be the one talking too much about AI agents and Azure deployments. See you in Cologne.🏆 Agents League Winner Spotlight – Reasoning Agents Track
Agents League was designed to showcase what agentic AI can look like when developers move beyond single‑prompt interactions and start building systems that plan, reason, verify, and collaborate. Across three competitive tracks—Creative Apps, Reasoning Agents, and Enterprise Agents—participants had two weeks to design and ship real AI agents using production‑ready Microsoft and GitHub tools, supported by live coding battles, community AMAs, and async builds on GitHub. Today, we’re excited to spotlight the winning project for the Reasoning Agents track, built on Microsoft Foundry: CertPrep Multi‑Agent System — Personalised Microsoft Exam Preparation by Athiq Ahmed. The Reasoning Agents Challenge Scenario The goal of the Reasoning Agents track challenge was to design a multi‑agent system capable of effectively assisting students in preparing for Microsoft certification exams. Participants were asked to build an agentic workflow that could understand certification syllabi, generate personalized study plans, assess learner readiness, and continuously adapt based on performance and feedback. The suggested reference architecture modeled a realistic learning journey: starting from free‑form student input, a sequence of specialized reasoning agents collaboratively curated Microsoft Learn resources, produced structured study plans with timelines and milestones, and maintained learner engagement through reminders. Once preparation was complete, the system shifted into an assessment phase to evaluate readiness and either recommend the appropriate Microsoft certification exam or loop back into targeted remediation—emphasizing reasoning, decision‑making, and human‑in‑the‑loop validation at every step. All details are available here: agentsleague/starter-kits/2-reasoning-agents at main · microsoft/agentsleague. The Winning Project: CertPrep Multi‑Agent System The CertPrep Multi‑Agent System is an AI solution for personalized Microsoft certification exam preparation, supporting nine certification exam families. At a high level, the system turns free‑form learner input into a structured certification plan, measurable progress signals, and actionable recommendations—demonstrating exactly the kind of reasoned orchestration this track was designed to surface. Inside the Multi‑Agent Architecture At its core, the system is designed as a multi‑agent pipeline that combines sequential reasoning, parallel execution, and human‑in‑the‑loop gates, with traceability and responsible AI guardrails. The solution is composed of eight specialized reasoning agents, each focused on a specific stage of the learning journey: LearnerProfilingAgent – Converts free‑text background information into a structured learner profile using Microsoft Foundry SDK (with deterministic fallbacks). StudyPlanAgent – Generates a week‑by‑week study plan using a constrained allocation algorithm to respect the learner’s available time. LearningPathCuratorAgent – Maps exam domains to curated Microsoft Learn resources with trusted URLs and estimated effort. ProgressAgent – Computes a weighted readiness score based on domain coverage, time utilization, and practice performance. AssessmentAgent – Generates and evaluates domain‑proportional mock exams. CertificationRecommendationAgent – Issues a clear “GO / CONDITIONAL GO / NOT YET” decision with remediation steps and next‑cert suggestions. Throughout the pipeline, a 17‑rule Guardrails Pipeline enforces validation checks at every agent boundary, and two explicit human‑in‑the‑loop gates ensure that decisions are made only when sufficient learner confirmation or data is present. CertPrep leverages Microsoft Foundry Agent Service and related tooling to run this reasoning pipeline reliably and observably: Managed agents via Foundry SDK Structured JSON outputs using GPT‑4o (JSON mode) with conservative temperature settings Guardrails enforced through Azure Content Safety Parallel agent fan‑out using concurrent execution Typed contracts with Pydantic for every agent boundary AI-assisted development with GitHub Copilot, used throughout for code generation, refactoring, and test scaffolding Notably, the full pipeline is designed to run in under one second in mock mode, enabling reliable demos without live credentials. User Experience: From Onboarding to Exam Readiness Beyond its backend architecture, CertPrep places strong emphasis on clarity, transparency, and user trust through a well‑structured front‑end experience. The application is built with Streamlit and organized as a 7‑tab interactive interface, guiding learners step‑by‑step through their preparation journey. From a user’s perspective, the flow looks like this: Profile & Goals Input Learners start by describing their background, experience level, and certification goals in natural language. The system immediately reflects how this input is interpreted by displaying the structured learner profile produced by the profiling agent. Learning Path & Study Plan Visualization Once generated, the study plan is presented using visual aids such as Gantt‑style timelines and domain breakdowns, making it easy to understand weekly milestones, expected effort, and progress over time. Progress Tracking & Readiness Scoring As learners move forward, the UI surfaces an exam‑weighted readiness score, combining domain coverage, study plan adherence, and assessment performance—helping users understand why the system considers them ready (or not yet). Assessments and Feedback Practice assessments are generated dynamically, and results are reported alongside actionable feedback rather than just raw scores. Transparent Recommendations Final recommendations are presented clearly, supported by reasoning traces and visual summaries, reinforcing trust and explainability in the agent’s decision‑making. The UI also includes an Admin Dashboard and demo‑friendly modes, enabling judges, reviewers, or instructors to inspect reasoning traces, switch between live and mock execution, and demonstrate the system reliably without external dependencies. Why This Project Stood Out This project embodies the spirit of the Reasoning Agents track in several ways: ✅ Clear separation of reasoning roles, instead of prompt‑heavy monoliths ✅ Deterministic fallbacks and guardrails, critical for educational and decision‑support systems ✅ Observable, debuggable workflows, aligned with Foundry’s production goals ✅ Explainable outputs, surfaced directly in the UX It demonstrates how agentic patterns translate cleanly into maintainable architectures when supported by the right platform abstractions.

Introduction For over a decade, CI/CD (Continuous Integration and Continuous Deployment) has been the backbone of modern software engineering. It helped teams move from manual, error-prone deployments to automated, reliable pipelines. But today, we are standing at the edge of another transformation—one that is far more powerful. Welcome to the era of Continuous AI. This new paradigm is not just about automating pipelines—it’s about building self-improving, intelligent systems that can analyze, decide, and act with minimal human intervention. With the emergence of AI-powered workflows inside GitHub, automation is evolving from rule-based execution to context-aware decision-making. This article explores: What Continuous AI is How it differs from CI/CD Real-world use cases Architecture patterns Challenges and best practices What the future holds for engineering teams The Evolution: From CI to CI/CD to Continuous AI 1. Continuous Integration (CI) Developers merge code frequently Automated builds and tests validate changes Goal: Catch issues early 2. Continuous Deployment (CD) Code automatically deployed to production Reduced manual intervention Goal: Faster delivery 3. Continuous AI (The Next Step) Systems don’t just execute—they think and improve AI agents analyze code, detect issues, suggest fixes, and even implement them Goal: Autonomous software evolution What is Continuous AI? Continuous AI is a model where: Software systems continuously improve themselves using AI-driven insights and automated actions. Instead of static pipelines, you get: Intelligent workflows Context-aware automation Self-healing repositories Autonomous decision-making systems Key Characteristics Feature CI/CD Continuous AI Execution Rule-based AI-driven Flexibility Low High Decision-making Predefined Dynamic Learning None Continuous Output Build & deploy Improve & optimize Why Continuous AI Matters Traditional automation has limitations: It cannot adapt to new patterns It cannot reason about code quality It cannot proactively improve systems Continuous AI solves these problems by introducing: Context awareness Learning from past data Proactive optimization This leads to: Faster development cycles Higher code quality Reduced operational overhead Smarter engineering teams Core Components of Continuous AI in GitHub 1. AI Agents AI agents act as autonomous workers inside your repository. They can: Review pull requests Suggest improvements Generate tests Fix bugs 2. Agentic Workflows Unlike YAML pipelines, these workflows: Are written in natural language or simplified formats Use AI to interpret intent Adapt based on context 3. Event-Driven Intelligence Workflows trigger on events like: Pull request creation Issue updates Failed builds But instead of just reacting, they: Analyze the situation Decide the best course of action 4. Feedback Loops Continuous AI systems improve over time using: Past PR data Test failures Deployment outcomes CI/CD vs Continuous AI: A Deep Comparison Traditional CI/CD Pipeline Developer pushes code Pipeline runs tests Build is generated Code is deployed ➡️ Everything is predefined and static Continuous AI Workflow Developer creates PR AI agent reviews code Suggests improvements Generates missing tests Fixes minor issues automatically Learns from feedback ➡️ Dynamic, intelligent, and evolving Real-World Use Cases 1. Automated Pull Request Reviews AI agents can: Detect code smells Suggest optimizations Ensure coding standards 2. Self-Healing Repositories Automatically fix failing builds Update dependencies Resolve merge conflicts 3. Intelligent Test Generation Generate test cases based on code changes Improve coverage over time 4. Issue Triage Automation Categorize issues Assign priorities Route to correct teams 5. Documentation Automation Auto-generate README updates Keep documentation in sync with code Architecture of Continuous AI Systems A typical architecture includes: Layer 1: Event Sources GitHub events (PRs, commits, issues) Layer 2: AI Decision Engine LLM-based agents Context analysis Task planning Layer 3: Action Layer GitHub Actions Scripts Automation tools Layer 4: Feedback Loop Logs Metrics Model improvement Multi-Agent Systems: The Next Level Continuous AI becomes more powerful when multiple agents collaborate. Example Setup: Code Review Agent → Reviews PRs Test Agent → Generates tests Security Agent → Scans vulnerabilities Docs Agent → Updates documentation These agents: Communicate with each other Share context Coordinate tasks ➡️ This creates a virtual AI engineering team Benefits for Engineering Teams 1. Increased Productivity Developers spend less time on repetitive tasks. 2. Better Code Quality Continuous improvements ensure cleaner codebases. 3. Faster Time-to-Market Automation reduces bottlenecks. 4. Reduced Burnout Engineers focus on innovation instead of maintenance. Challenges and Risks 1. Over-Automation Too much automation can reduce human oversight. 2. Security Concerns AI workflows may misuse permissions if not controlled. 3. Trust Issues Teams may hesitate to rely on AI decisions. 4. Cost of AI Operations Running AI agents continuously can increase costs. Best Practices for Implementing Continuous AI 1. Start Small Begin with: PR review automation Test generation 2. Human-in-the-Loop Ensure: Critical decisions require approval 3. Use Least Privilege Restrict workflow permissions. 4. Monitor and Measure Track: Accuracy Impact Cost 5. Build Feedback Loops Continuously improve models and workflows. Future of GitHub Automation The future is heading toward: Fully autonomous repositories AI-driven engineering teams Continuous optimization of software systems We may soon see: Repos that refactor themselves Systems that predict failures before they occur AI architects designing system improvements Conclusion CI/CD transformed how we build and deliver software. But Continuous AI is set to transform how software evolves. It moves us from: “Automating tasks” → “Automating intelligence” For engineering leaders, this is not just a technical shift—it’s a strategic advantage. Early adopters of Continuous AI will build faster, smarter, and more resilient systems. The question is no longer: “Should we adopt AI in our workflows?” But: “How fast can we transition to Continuous AI?”AZD for Beginners: A Practical Introduction to Azure Developer CLI
If you are learning how to get an application from your machine into Azure without stitching together every deployment step by hand, Azure Developer CLI, usually shortened to azd , is one of the most useful tools to understand early. It gives developers a workflow-focused command line for provisioning infrastructure, deploying application code, wiring environment settings, and working with templates that reflect real cloud architectures rather than toy examples. This matters because many beginners hit the same wall when they first approach Azure. They can build a web app locally, but once deployment enters the picture they have to think about resource groups, hosting plans, databases, secrets, monitoring, configuration, and repeatability all at once. azd reduces that operational overhead by giving you a consistent developer workflow. Instead of manually creating each resource and then trying to remember how everything fits together, you start with a template or an azd -compatible project and let the tool guide the path from local development to a running Azure environment. If you are new to the tool, the AZD for Beginners learning resources are a strong place to start. The repository is structured as a guided course rather than a loose collection of notes. It covers the foundations, AI-first deployment scenarios, configuration and authentication, infrastructure as code, troubleshooting, and production patterns. In other words, it does not just tell you which commands exist. It shows you how to think about shipping modern Azure applications with them. What Is Azure Developer CLI? The Azure Developer CLI documentation on Microsoft Learn, azd is an open-source tool designed to accelerate the path from a local development environment to Azure. That description is important because it explains what the tool is trying to optimise. azd is not mainly about managing one isolated Azure resource at a time. It is about helping developers work with complete applications. The simplest way to think about it is this. Azure CLI, az , is broad and resource-focused. It gives you precise control over Azure services. Azure Developer CLI, azd , is application-focused. It helps you take a solution made up of code, infrastructure definitions, and environment configuration and push that solution into Azure in a repeatable way. Those tools are not competitors. They solve different problems and often work well together. For a beginner, the value of azd comes from four practical benefits: It gives you a consistent workflow built around commands such as azd init , azd auth login , azd up , azd show , and azd down . It uses templates so you do not need to design every deployment structure from scratch on day one. It encourages infrastructure as code through files such as azure.yaml and the infra folder. It helps you move from a one-off deployment towards a repeatable development workflow that is easier to understand, change, and clean up. Why Should You Care About azd A lot of cloud frustration comes from context switching. You start by trying to deploy an app, but you quickly end up learning five or six Azure services, authentication flows, naming rules, environment variables, and deployment conventions all at once. That is not a good way to build confidence. azd helps by giving a workflow that feels closer to software delivery than raw infrastructure management. You still learn real Azure concepts, but you do so through an application lens. You initialise a project, authenticate, provision what is required, deploy the app, inspect the result, and tear it down when you are done. That sequence is easier to retain because it mirrors the way developers already think about shipping software. This is also why the AZD for Beginners resource is useful. It does not assume every reader is already comfortable with Azure. It starts with foundation topics and then expands into more advanced paths, including AI deployment scenarios that use the same core azd workflow. That progression makes it especially suitable for students, self-taught developers, workshop attendees, and engineers who know how to code but want a clearer path into Azure deployment. What You Learn from AZD for Beginners The AZD for Beginners course is structured as a learning journey rather than a single quickstart. That matters because azd is not just a command list. It is a deployment workflow with conventions, patterns, and trade-offs. The course helps readers build that mental model gradually. At a high level, the material covers: Foundational topics such as what azd is, how to install it, and how the basic deployment loop works. Template-based development, including how to start from an existing architecture rather than building everything yourself. Environment configuration and authentication practices, including the role of environment variables and secure access patterns. Infrastructure as code concepts using the standard azd project structure. Troubleshooting, validation, and pre-deployment thinking, which are often ignored in beginner content even though they matter in real projects. Modern AI and multi-service application scenarios, showing that azd is not limited to basic web applications. One of the strongest aspects of the course is that it does not stop at the first successful deployment. It also covers how to reason about configuration, resource planning, debugging, and production readiness. That gives learners a more realistic picture of what Azure development work actually looks like. The Core azd Workflow The official overview on Microsoft Learn and the get started guide both reinforce a simple but important idea: most beginners should first understand the standard workflow before worrying about advanced customisation. That workflow usually looks like this: Install azd . Authenticate with Azure. Initialise a project from a template or in an existing repository. Run azd up to provision and deploy. Inspect the deployed application. Remove the resources when finished. Here is a minimal example using an existing template: # Install azd on Windows winget install microsoft.azd # Check that the installation worked azd version # Sign in to your Azure account azd auth login # Start a project from a template azd init --template todo-nodejs-mongo # Provision Azure resources and deploy the app azd up # Show output values such as the deployed URL azd show # Clean up everything when you are done learning azd down --force --purge This sequence is important because it teaches beginners the full lifecycle, not only deployment. A lot of people remember azd up and forget the cleanup step. That leads to wasted resources and avoidable cost. The azd down --force --purge step is part of the discipline, not an optional extra. Installing azd and Verifying Your Setup The official install azd guide on Microsoft Learn provides platform-specific instructions. Because this repository targets developer learning, it is worth showing the common install paths clearly. # Windows winget install microsoft.azd # macOS brew tap azure/azd && brew install azd # Linux curl -fsSL https://aka.ms/install-azd.sh | bash After installation, verify the tool is available: azd version That sounds obvious, but it is worth doing immediately. Many beginner problems come from assuming the install completed correctly, only to discover a path issue or outdated version later. Verifying early saves time. The Microsoft Learn installation page also notes that azd installs supporting tools such as GitHub CLI and Bicep CLI within the tool's own scope. For a beginner, that is helpful because it removes some of the setup friction you might otherwise need to handle manually. What Happens When You Run azd up ? One of the most important questions is what azd up is actually doing. The short answer is that it combines provisioning and deployment into one workflow. The longer answer is where the learning value sits. When you run azd up , the tool looks at the project configuration, reads the infrastructure definition, determines which Azure resources need to exist, provisions them if necessary, and then deploys the application code to those resources. In many templates, it also works with environment settings and output values so that the project becomes reproducible rather than ad hoc. That matters because it teaches a more modern cloud habit. Instead of building infrastructure manually in the portal and then hoping you can remember how you did it, you define the deployment shape in source-controlled files. Even at beginner level, that is the right habit to learn. Understanding the Shape of an azd Project The Azure Developer CLI templates overview explains the standard project structure used by azd . If you understand this structure early, templates become much less mysterious. A typical azd project contains: azure.yaml to describe the project and map services to infrastructure targets. An infra folder containing Bicep or Terraform files for infrastructure as code. A src folder, or equivalent source folders, containing the application code that will be deployed. A local .azure folder to store environment-specific settings for the project. Here is a minimal example of what an azure.yaml file can look like in a simple app: name: beginner-web-app metadata: template: beginner-web-app services: web: project: ./src/web host: appservice This file is small, but it carries an important idea. azd needs a clear mapping between your application code and the Azure service that will host it. Once you see that, the tool becomes easier to reason about. You are not invoking magic. You are describing an application and its hosting model in a standard way. Start from a Template, Then Learn the Architecture Beginners often assume that using a template is somehow less serious than building something from scratch. In practice, it is usually the right place to begin. The official docs for templates and the Awesome AZD gallery both encourage developers to start from an existing architecture when it matches their goals. That is a sound learning strategy for two reasons. First, it lets you experience a working deployment quickly, which builds confidence. Second, it gives you a concrete project to inspect. You can look at azure.yaml , explore the infra folder, inspect the app source, and understand how the pieces connect. That teaches more than reading a command reference in isolation. The AZD for Beginners material also leans into this approach. It includes chapter guidance, templates, workshops, examples, and structured progression so that readers move from successful execution into understanding. That is much more useful than a single command demo. A practical beginner workflow looks like this: # Pick a known template azd init --template todo-nodejs-mongo # Review the files that were created or cloned # - azure.yaml # - infra/ # - src/ # Deploy it azd up # Open the deployed app details azd show Once that works, do not immediately jump to a different template. Spend time understanding what was deployed and why. Where AZD for Beginners Fits In The official docs are excellent for accurate command guidance and conceptual documentation. The AZD for Beginners repository adds something different: a curated learning path. It helps beginners answer questions such as these: Which chapter should I start with if I know Azure a little but not azd ? How do I move from a first deployment into understanding configuration and authentication? What changes when the application becomes an AI application rather than a simple web app? How do I troubleshoot failures instead of copying commands blindly? The repository also points learners towards workshops, examples, a command cheat sheet, FAQ material, and chapter-based exercises. That makes it particularly useful in teaching contexts. A lecturer or workshop facilitator can use it as a course backbone, while an individual learner can work through it as a self-study track. For developers interested in AI, the resource is especially timely because it shows how the same azd workflow can be used for AI-first solutions, including scenarios connected to Microsoft Foundry services and multi-agent architectures. The important beginner lesson is that the workflow stays recognisable even as the application becomes more advanced. Common Beginner Mistakes and How to Avoid Them A good introduction should not only explain the happy path. It should also point out the places where beginners usually get stuck. Skipping authentication checks. If azd auth login has not completed properly, later commands will fail in ways that are harder to interpret. Not verifying the installation. Run azd version immediately after install so you know the tool is available. Treating templates as black boxes. Always inspect azure.yaml and the infra folder so you understand what the project intends to provision. Forgetting cleanup. Learning environments cost money if you leave them running. Use azd down --force --purge when you are finished experimenting. Trying to customise too early. First get a known template working exactly as designed. Then change one thing at a time. If you do hit problems, the official troubleshooting documentation and the troubleshooting sections inside AZD for Beginners are the right next step. That is a much better habit than searching randomly for partial command snippets. How I Would Approach AZD as a New Learner If I were introducing azd to a student or a developer who is comfortable with code but new to Azure delivery, I would keep the learning path tight. Read the official What is Azure Developer CLI? overview so the purpose is clear. Install the tool using the Microsoft Learn install guide. Work through the opening sections of AZD for Beginners. Deploy one template with azd init and azd up . Inspect azure.yaml and the infrastructure files before making any changes. Run azd down --force --purge so the lifecycle becomes a habit. Only then move on to AI templates, configuration changes, or custom project conversion. That sequence keeps the cognitive load manageable. It gives you one successful deployment, one architecture to inspect, and one repeatable workflow to internalise before adding more complexity. Why azd Is Worth Learning Now azd matters because it reflects how modern Azure application delivery is actually done: repeatable infrastructure, source-controlled configuration, environment-aware workflows, and application-level thinking rather than isolated portal clicks. It is useful for straightforward web applications, but it becomes even more valuable as systems gain more services, more configuration, and more deployment complexity. That is also why the AZD for Beginners resource is worth recommending. It gives new learners a structured route into the tool instead of leaving them to piece together disconnected docs, samples, and videos on their own. Used alongside the official Microsoft Learn documentation, it gives you both accuracy and progression. Key Takeaways azd is an application-focused Azure deployment tool, not just another general-purpose CLI. The core beginner workflow is simple: install, authenticate, initialise, deploy, inspect, and clean up. Templates are not a shortcut to avoid learning. They are a practical way to learn architecture through working examples. AZD for Beginners is valuable because it turns the tool into a structured learning path. The official Microsoft Learn documentation for Azure Developer CLI should remain your grounding source for commands and platform guidance. Next Steps If you want to keep going, start with these resources: AZD for Beginners for the structured course, examples, and workshop materials. Azure Developer CLI documentation on Microsoft Learn for official command, workflow, and reference guidance. Install azd if you have not set up the tool yet. Deploy an azd template for the first full quickstart. Azure Developer CLI templates overview if you want to understand the project structure and template model. Awesome AZD if you want to browse starter architectures. If you are teaching others, this is also a good sequence for a workshop: start with the official overview, deploy one template, inspect the project structure, and then use AZD for Beginners as the path for deeper learning. That gives learners both an early win and a solid conceptual foundation.Agents League: Meet the Winners
Agents League brought together developers from around the world to build AI agents using Microsoft's developer tools. With 100+ submissions across three tracks, choosing winners was genuinely difficult. Today, we're proud to announce the category champions. 🎨 Creative Apps Winner: CodeSonify View project CodeSonify turns source code into music. As a genuinely thoughtful system, its functions become ascending melodies, loops create rhythmic patterns, conditionals trigger chord changes, and bugs produce dissonant sounds. It supports 7 programming languages and 5 musical styles, with each language mapped to its own key signature and code complexity directly driving the tempo. What makes CodeSonify stand out is the depth of execution. CodeSonify team delivered three integrated experiences: a web app with real-time visualization and one-click MIDI export, an MCP server exposing 5 tools inside GitHub Copilot in VS Code Agent Mode, and a diff sonification engine that lets you hear a code review. A clean refactor sounds harmonious. A messy one sounds chaotic. The team even built the MIDI generator from scratch in pure TypeScript with zero external dependencies. Built entirely with GitHub Copilot assistance, this is one of those projects that makes you think about code differently. 🧠 Reasoning Agents Winner: CertPrep Multi-Agent System View project CertPrep Multi-Agent System team built a production-grade 8-agent system for personalized Microsoft certification exam preparation, supporting 9 exam families including AI-102, AZ-204, AZ-305, and more. Each agent has a distinct responsibility: profiling the learner, generating a week-by-week study schedule, curating learning paths, tracking readiness, running mock assessments, and issuing a GO / CONDITIONAL GO / NOT YET booking recommendation. The engineering behind the scene here is impressive. A 3-tier LLM fallback chain ensures the system runs reliably even without Azure credentials, with the full pipeline completing in under 1 second in mock mode. A 17-rule guardrail pipeline validates every agent boundary. Study time allocation uses the Largest Remainder algorithm to guarantee no domain is silently zeroed out. 342 automated tests back it all up. This is what thoughtful multi-agent architecture looks like in practice. 💼 Enterprise Agents Winner: Whatever AI Assistant (WAIA) View project WAIA is a production-ready multi-agent system for Microsoft 365 Copilot Chat and Microsoft Teams. A workflow agent routes queries to specialized HR, IT, or Fallback agents, transparently to the user, handling both RAG-pattern Q&A and action automation — including IT ticket submission via a SharePoint list. Technically, it's a showcase of what serious enterprise agent development looks like: a custom MCP server secured with OAuth Identity Passthrough, streaming responses via the OpenAI Responses API, Adaptive Cards for human-in-the-loop approval flows, a debug mode accessible directly from Teams or Copilot, and full OpenTelemetry integration visible in the Foundry portal. Franck also shipped end-to-end automated Bicep deployment so the solution can land in any Azure environment. It's polished, thoroughly documented, and built to be replicated.
