Your Entire Agentic AI Workflow, Now Inside VS Code: New Course Available
If you build with AI, you know the tax: jumping between a browser portal to pick a model, a terminal to run it, a separate playground to test a prompt, and finally your editor to write the code. Every context switch is a small drain on focus—and it adds up. What if the whole loop lived in the one tool you never leave? That's the promise of the Foundry Toolkit for Visual Studio Code, and it's exactly what our new VS Code Learn: Foundry Toolkit video series is here to show you
Mind the Specs: Grading formal specifications and KPIs as artefacts for LLM-driven code generation
Large language models now write code straight from a prompt, but the specification in between is never checked, and a model asked to judge its own work brings the same blind spots to the review. We built a pipeline that lifts a plain-language requirements bundle into two graded specifications (a formal Alloy model and a set of numerical KPI targets), scores both before a single line of code is written, and hands the graded result to the code generator. It starts from GitHub Spec Kit and the Azure Well-Architected Framework. Here is what we built, and what we learned from running it at scale. The problem Writing software used to be four separate activities: gathering requirements, writing a specification, verifying it, and implementing it. A language model collapses all four into a single step. Two of those activities used to give us a quality signal before any code existed: a formal specification you could inspect, and measurable targets an implementation had to hit. The prompt-to-code loop inherits neither. There is no externally observable signal, before a line of code is written, that the requirements a model received are even well-formed enough to drive a correct implementation. You might think the model could just check its own work. It cannot do so reliably. Ask a language model to check the logic it just wrote: not only will it bring the same blind spot to the review, but its stochastic nature will make it produce different answers on each run. A SAT solver does not behave this way. Its verdict is deterministic: the same specification produces the same verdict every time. The thing that historically kept formal specification out of everyday development was never its rigour, it was the cost of writing the specification by hand. And that is exactly the step a language model can now do. What we built We built an agentic pipeline that sits between the requirements and the generated code. In plain terms it takes the requirements once, turns them into two things that can be checked by a machine: a precise description of rules that the system must obey, and a set of measurable targets that the system must hit. These artefacts are both graded, and are handed to the code generator. We split the work in two and gave each half to the tool that is good at it. The language model does the creative part, turning messy prose into formal structure. Deterministic checks, not the model's own opinion, grade what it produces. From a single Spec Kit artefacts bundle the pipeline builds two graded specifications before any code exists, and then carries both into code generation. Since these grades are computed deterministically rather than just generated, you can actually trust them. The input is a GitHub Spec Kit bundle. Spec Kit is an open-source, specification-first toolkit: instead of prompting for code directly, you describe what you want to build, and it produces a set of structured artefacts, a feature specification, a data model, and a set of API contracts. Our pipeline reads that bundle and turns it into the two graded specifications in parallel. overview. Spec Kit artefacts on the left. The Alloy lifter (with SAT solver and the attack step) and the KPI agent run in parallel. Their graded outputs are merged into a verification report that feeds the guided code generator. A dashed baseline path feeds the goal alone to the generator for comparison. Lift the requirements into a formal model The first half is structural. An Alloy lifter translates the requirements into a formal model written in Alloy, a specification language whose rules a SAT solver can check exhaustively, and whose verdict is deterministic, so the grade never depends on asking an LLM what it thinks. A banking requirement like "zero balance discrepancies" becomes a precise, checkable rule: the money leaving one account and the money arriving in another must always add up to the balances you started with, so a transfer can never quietly create or destroy money. The solver searches for any scenario that would break the rule. We modified Spec Kit's templates to force the model to output functional requirements and their corresponding Alloy code blocks in a structured format. Against the stock templates, that change alone nearly doubled the Alloy code compilation rate, jumping from 40 to 74 percent. A machine-written specification cannot be trusted, though, so the lifter does more than write it: it attacks it. Each load-bearing rule is deliberately broken by clearing its body and injecting a clause that forces a violation and the solver is re-run on the broken model. If the solver fails after this mutation, the original rule genuinely caught the violation it was meant to catch. If it still passes, the rule never really constrained anything on its own. Mutation testing usually grades a test suite against a specification that is assumed correct; here the roles are reversed, and the specification itself is on trial. Turn the requirements into measurable targets The second half is measurable. A KPI agent takes the same Spec Kit bundle, retrieves the most relevant principles from the Azure Well-Architected Framework, and derives numerical targets in the Goal-Question-Metric style. Each target carries an explicit threshold, a direction, and a measurement method, the kind of target a monitoring tool could actually track. Where earlier automated approaches stopped at describing quality in words, this half emits the actual numbers an implementation has to satisfy. And the knowledge base is a setting, not a fixture: swapping the Well-Architected Framework for ISO 25010, the NIST Cybersecurity Framework, or Google's SRE workbook requires zero changes to the underlying code. Review the report before any code Both graded halves merge into one human-readable verification report: the patterns the model applied, which rules passed, the counterexamples the solver found, the attack results, and the KPI threshold table. A developer reads it first and can see exactly where the specification is weak: a rule that passed for the wrong reason, or a requirement that nothing covers. After revising the specification, they re-run the lifting phase. Because the process is cached, re-runs are cheap, allowing the developer to loop until the report looks perfect, all before any code exists. The work shifts from reviewing generated code after the fact to curating a specification and reading a report before anything is built. Carry the graded context into code generation Only then does the report do its real job. In the guided pipeline, the merged report becomes the context handed to a code generator, which is asked to implement each rule, requirement, and KPI threshold and to leave markers tracing the code back to them. A baseline generator gets only the plain-language goal. Same generator, same settings; the only difference is whether it can see the graded specification. Feeding graded artefacts, rather than raw prose, into code generation is the piece that ties the whole pipeline together. So three choices separate this from simply asking a model for a spec: the specification is attacked rather than trusted, the targets are numbers rather than prose, and what reaches the code generator is graded evidence rather than raw text. How we tested it We ran the pipeline at scale: 270 Alloy lifts and 1,930 KPI records, across three application domains chosen to differ sharply (banking, software-as-a-service, and healthcare), three levels of requirement detail, four knowledge bases, and three model tiers, with ten runs of each combination so a real effect could be told apart from noise. For the code-generation half, we generated two codes for each case, once with the graded report as context and once from the plain-language goal alone, and compared the two. What we found First, the foundation: the specifications proved gradeable. The rubric cleanly separated sound specifications from degenerate ones. Because it returned the same verdict run after run, the grades are reliable enough to act on. The three key observations are as follows: The model matters more than the prompt Of the two knobs a practitioner controls, the model you choose and the amount of detail you write, the model dominated by roughly nine to one. A weak model could not be rescued by richer requirements. But you do not need the most expensive one: a mid-tier model delivered about 98 percent of the best model's quality at under a third of the cost and about half the time. The cheapest tier was a false economy, producing a model the analyser could even load only 23 percent of the time. More detail can backfire More requirements are not always better. Sparse and standard requirements scored the same, but over-specified requirements collapsed: KPI quality fell from about 0.89 to about 0.73, and the effect held across all four knowledge bases. Pile in too much numerical detail and the pipeline starts echoing the numbers it was handed instead of deriving sound ones, which is the opposite of what more detail is supposed to buy. Graded context produces far better code This is the payoff, and it is the point of the whole pipeline. Across all nine combinations of domain and detail, code generated with the graded verification context scored about 8 out of 10, against about 1 out of 10 for the same generator given only the plain-language goal. The guided code carried the traceability back to each requirement, the named rules, and the structural patterns that a bare prompt gives us no way to know about. This part of the study is a single run per combination, so we report the size and the consistency of the gap rather than a precise average, but the gap was large and it held in every case. What this means for you Four things to take from our study into your own work: Write requirements at a standard, middle level of detail. Not sparse, and not exhaustively numerical. The middle is the sweet spot on both halves of the specification. Reach for a capable mid-tier model before you invest in heavy prompt engineering. Model choice moves quality more than requirement detail does, and the mid tier is the value leader. Give the code generator externally graded context instead of letting it specify for itself. That is where most of the quality gain came from. Treat the knowledge base as a setting worth tuning, not a fixed ingredient. Each is a recommendation that data supports under the conditions we tested, not a universal law. The limit Every grade measures structure, not meaning. A high score says the specification is well-formed, discriminating, and stable. It does not say whether the invariants are the right ones, or the thresholds are the right ones for your deployment. A specification can be perfectly well-formed and still describe the wrong system. That judgement stays with a human, which is where we think it belongs. The pipeline is built to make that judgement efficient by moving it earlier, to curating the specification and reading the report, rather than to remove it. Generated code should not be shipped end to end without human validation. Try it The full pipeline, every input, and the artefacts behind every figure are in the project repository.

Build an AI-Powered Space Invaders Game: Integrating LLMs into HTML5 Games with Microsoft Foundry Local Introduction What if your game could talk back to you? Imagine playing Space Invaders while an AI commander taunts you during battle, delivers personalized mission briefings, and provides real-time feedback based on your performance. This isn't science fiction it's something you can build today using HTML, JavaScript, and a locally-running AI model. In this tutorial, we'll explore how to create an HTML5 game with integrated Large Language Model (LLM) features using Microsoft Foundry Local. You'll learn how to combine classic game development with modern AI capabilities, all running entirely on your own machine—no cloud services, no API costs, no internet connection required during gameplay. We'll be working with the Space Invaders - AI Commander Edition project, which demonstrates exactly how to architect games that leverage local AI. Whether you're a student learning game development, exploring AI integration patterns, or building your portfolio, this guide provides practical, hands-on experience with technologies that are reshaping how we build interactive applications. What You'll Learn By the end of this tutorial, you'll understand how to combine traditional web development with local AI inference. These skills transfer directly to building chatbots, interactive tutorials, AI-enhanced productivity tools, and any application where you want intelligent, context-aware responses. Set up Microsoft Foundry Local for running AI models on your machine Understand the architecture of games that integrate LLM features Use GitHub Copilot CLI to accelerate your development workflow Implement AI-powered game features like dynamic commentary and adaptive feedback Extend the project with your own creative AI features Why Local AI for Games? Before diving into the code, let's understand why running AI locally matters for game development. Traditional cloud-based AI services have limitations that make them impractical for real-time gaming experiences. Latency is the first challenge. Cloud API calls typically take 500ms to several seconds, an eternity in a game running at 60 frames per second. Local inference can respond in tens of milliseconds, enabling AI responses that feel instantaneous and natural. When an enemy ship appears, your AI commander can taunt you immediately, not three seconds later. Cost is another consideration. Cloud AI services charge per token, which adds up quickly when generating dynamic content during gameplay. Local models have zero per-use cost, once installed, they run entirely on your hardware. This frees you to experiment without worrying about API bills. Privacy and offline capability complete the picture. Local AI keeps all data on your machine, perfect for games that might handle player information. And since nothing requires internet connectivity, your game works anywhere, on planes, in areas with poor connectivity, or simply when you want to play without network access. Understanding Microsoft Foundry Local Microsoft Foundry Local is a runtime that enables you to run small language models (SLMs) directly on your computer. It's designed for developers who want to integrate AI capabilities into applications without requiring cloud infrastructure. Think of it as having a miniature AI assistant living on your laptop. Foundry Local handles the complex work of loading AI models, managing memory, and processing inference requests through a simple API. You send text prompts, and it returns AI-generated responses, all happening locally on your CPU or GPU. The models are optimized to run efficiently on consumer hardware, so you don't need a supercomputer. For our Space Invaders game, Foundry Local powers the "AI Commander" feature. During gameplay, the game sends context about what's happening, your score, accuracy, current level, enemies remaining and receives back contextual commentary, taunts, and encouragement. The result feels like playing alongside an AI companion who actually understands the game. Setting Up Your Development Environment Let's get your machine ready for AI-powered game development. We'll install Foundry Local, clone the project, and verify everything works. The entire setup takes about 10-15 minutes. Step 1: Install Microsoft Foundry Local Foundry Local installation varies by operating system. Open your terminal and run the appropriate command: # Windows (using winget) winget install Microsoft.FoundryLocal # macOS (using Homebrew) brew install microsoft/foundrylocal/foundrylocal These commands download and install the Foundry Local runtime along with a default small language model. The installation includes everything needed to run AI inference locally. Verify the installation by running: foundry --version If you see a version number, Foundry Local is ready. If you encounter errors, ensure you have administrator/sudo privileges and that your package manager is up to date. Step 2: Install Node.js (If Not Already Installed) Our game's AI features require a small Node.js server to communicate between the browser and Foundry Local. Check if Node.js is installed: node --version If you see a version number (v16 or higher recommended), you're set. Otherwise, install Node.js: # Windows winget install OpenJS.NodeJS.LTS # macOS brew install node # Linux sudo apt install nodejs npm Node.js provides the JavaScript runtime that powers our proxy server, bridging browser code with the local AI model. Step 3: Clone the Project Get the Space Invaders project onto your machine: git clone https://github.com/leestott/Spaceinvaders-FoundryLocal.git cd Spaceinvaders-FoundryLocal This downloads all game files, including the HTML interface, game logic, AI integration module, and server code. Step 4: Install Dependencies and Start the Server Install the Node.js packages and launch the AI-enabled server: npm install npm start The first command downloads required packages (primarily for the proxy server). The second starts the server, which listens for AI requests from the game. You should see output indicating the server is running on port 3001. Step 5: Play the Game Open your browser and navigate to: http://localhost:3001 You should see Space Invaders with "AI: ONLINE" displayed in the game HUD, indicating that AI features are active. Use arrow keys or A/D to move, SPACE to fire, and P to pause. The AI Commander will start providing commentary as you play! Understanding the Project Architecture Now that the game is running, let's explore how the different pieces fit together. Understanding this architecture will help you modify the game and apply these patterns to your own projects. The project follows a clean separation of concerns, with each file handling a specific responsibility: Spaceinvaders-FoundryLocal/ ├── index.html # Main game page and UI structure ├── styles.css # Retro arcade visual styling ├── game.js # Core game logic and rendering ├── llm.js # AI integration module ├── sound.js # Web Audio API sound effects ├── server.js # Node.js proxy for Foundry Local └── package.json # Project configuration index.html: Defines the game canvas and UI elements. It's the entry point that loads all other modules. game.js: Contains the game loop, physics, collision detection, scoring, and rendering logic. This is the heart of the game. llm.js: Handles all communication with the AI backend. It formats game state into prompts and processes AI responses. server.js: A lightweight Express server that proxies requests between the browser and Foundry Local. sound.js: Synthesizes retro sound effects using the Web Audio API—no audio files needed! How the AI Integration Works The magic of the AI Commander happens through a simple but powerful pattern. Let's trace the flow from gameplay event to AI response. When something interesting happens in the game, you clear a wave, achieve a combo, or lose a life, the game logic in game.js triggers an AI request. This request includes context about the current game state: your score, accuracy percentage, current level, lives remaining, and what just happened. The llm.js module formats this context into a prompt. For example, when you clear a wave with 85% accuracy, it might construct: You are an AI Commander in a Space Invaders game. The player just cleared wave 3 with 85% accuracy. Score: 12,500. Lives: 3. Provide a brief, enthusiastic comment (1-2 sentences). This prompt travels to server.js , which forwards it to Foundry Local. The AI model processes the prompt and generates a response like: "Impressive accuracy, pilot! Wave 3 didn't stand a chance. Keep that trigger finger sharp!" The response flows back through the server to the browser, where llm.js passes it to the game. The game displays the message in the HUD, creating the illusion of playing alongside an AI companion. This entire round trip typically completes in 50-200 milliseconds, fast enough to feel responsive without interrupting gameplay. Using GitHub Copilot CLI to Explore and Modify the Code GitHub Copilot CLI accelerates your development workflow by letting you ask questions and generate code directly in your terminal. Let's use it to understand and extend the Space Invaders project. Installing Copilot CLI If you haven't installed Copilot CLI yet, here's the quick setup: # Install GitHub CLI winget install GitHub.cli # Windows brew install gh # macOS # Authenticate with GitHub gh auth login # Add Copilot extension gh extension install github/gh-copilot # Verify installation gh copilot --help With Copilot CLI ready, you can interact with AI directly from your terminal while working on the project. Exploring Code with Copilot CLI Use Copilot to understand unfamiliar code. Navigate to the project directory and try: gh copilot explain "How does llm.js communicate with the server?" Copilot analyzes the code and explains the communication pattern, helping you understand the architecture without reading every line manually. You can also ask about specific functions: gh copilot explain "What does the generateEnemyTaunt function do?" This accelerates onboarding to unfamiliar codebases, a valuable skill when working with open source projects or joining teams. Generating New Features Want to add a new AI feature? Ask Copilot to help generate the code: gh copilot suggest "Create a function that asks the AI to generate a mission briefing at the start of each level, including the level number and a random mission objective" Copilot generates starter code that you can customize and integrate. This combination of AI-powered development tools and AI-integrated gameplay demonstrates how LLMs are transforming both how we build games and how games behave. Customizing the AI Commander The default AI Commander provides generic gaming commentary, but you can customize its personality and responses. Open llm.js to find the prompt templates that control AI behavior. Changing the AI's Personality The system prompt defines who the AI "is." Find the base prompt and modify it: // Original const systemPrompt = "You are an AI Commander in a Space Invaders game."; // Customized - Drill Sergeant personality const systemPrompt = `You are Sergeant Blaster, a gruff but encouraging drill sergeant commanding space cadets. Use military terminology, call the player "cadet," and be tough but fair.`; // Customized - Supportive Coach personality const systemPrompt = `You are Coach Nova, a supportive and enthusiastic gaming coach. Use encouraging language, celebrate small victories, and provide gentle guidance when players struggle.`; These personality changes dramatically alter the game's feel without changing any gameplay code. It's a powerful example of how AI can add variety to games with minimal development effort. Adding New Commentary Triggers Currently the AI responds to wave completions and game events. You can add new triggers in game.js : // Add AI commentary when player achieves a kill streak if (killStreak >= 5 && !streakCommentPending) { requestAIComment('killStreak', { count: killStreak }); streakCommentPending = true; } // Add AI reaction when player narrowly avoids death if (nearMissOccurred) { requestAIComment('nearMiss', { livesRemaining: lives }); } Each new trigger point adds another opportunity for the AI to engage with the player, making the experience more dynamic and personalized. Understanding the Game Features Beyond AI integration, the Space Invaders project demonstrates solid game development patterns worth studying. Let's explore the key features. Power-Up System The game includes eight different power-ups, each with unique effects: SPREAD (Orange): Fires three projectiles in a spread pattern LASER (Red): Powerful beam with high damage RAPID (Yellow): Dramatically increased fire rate MISSILE (Purple): Homing projectiles that track enemies SHIELD (Blue): Grants an extra life EXTRA LIFE (Green): Grants two extra lives BOMB (Red): Destroys all enemies on screen BONUS (Gold): Random score bonus between 250-750 points Power-ups demonstrate state management, tracking which power-up is active, applying its effects to player actions, and handling timeouts. Study the power-up code in game.js to understand how temporary state modifications work. Leaderboard System The game persists high scores using the browser's localStorage API: // Saving scores localStorage.setItem('spaceInvadersScores', JSON.stringify(scores)); // Loading scores const savedScores = localStorage.getItem('spaceInvadersScores'); const scores = savedScores ? JSON.parse(savedScores) : []; This pattern works for any data you want to persist between sessions—game progress, user preferences, or accumulated statistics. It's a simple but powerful technique for web games. Sound Synthesis Rather than loading audio files, the game synthesizes retro sound effects using the Web Audio API in sound.js . This approach has several benefits: no external assets to load, smaller project size, and complete control over sound parameters. Examine how oscillators and gain nodes combine to create laser sounds, explosions, and victory fanfares. This knowledge transfers directly to any web project requiring audio feedback. Extending the Project: Ideas for Students Ready to make the project your own? Here are ideas ranging from beginner-friendly to challenging, each teaching valuable skills. Beginner: Customize Visual Theme Modify styles.css to create a new visual theme. Try changing the color scheme from green to blue, or create a "sunset" theme with orange and purple gradients. This builds CSS skills while making the game feel fresh. Intermediate: Add New Enemy Types Create a new enemy class in game.js with different movement patterns. Perhaps enemies that move in sine waves, or boss enemies that take multiple hits. This teaches object-oriented programming and game physics. Intermediate: Expand AI Interactions Add new AI features like: Pre-game mission briefings that set up the story Dynamic difficulty hints when players struggle Post-game performance analysis and improvement suggestions AI-generated names for enemy waves Advanced: Multiplayer Commentary Modify the game for two-player support and have the AI provide play-by-play commentary comparing both players' performance. This combines game networking concepts with advanced AI prompting. Advanced: Voice Integration Use the Web Speech API to speak the AI Commander's responses aloud. This creates a more immersive experience and demonstrates browser speech synthesis capabilities. Troubleshooting Common Issues If something isn't working, here are solutions to common problems. "AI: OFFLINE" Displayed in Game This means the game can't connect to the AI server. Check that: The server is running ( npm start shows no errors) You're accessing the game via http://localhost:3001 , not directly opening the HTML file Foundry Local is installed correctly ( foundry --version works) Server Won't Start If npm start fails: Ensure you ran npm install first Check that port 3001 isn't already in use by another application Verify Node.js is installed ( node --version ) AI Responses Are Slow Local AI performance depends on your hardware. If responses feel sluggish: Close other resource-intensive applications Ensure your laptop is plugged in (battery mode may throttle CPU) Consider that first requests may be slower as the model loads Key Takeaways Local AI enables real-time game features: Microsoft Foundry Local provides fast, free, private AI inference perfect for gaming applications Clean architecture matters: Separating game logic, AI integration, and server code makes projects maintainable and extensible AI personality is prompt-driven: Changing a few lines of prompt text completely transforms how the AI interacts with players Copilot CLI accelerates learning: Use it to explore unfamiliar code and generate new features quickly The patterns transfer everywhere: Skills from this project apply to chatbots, assistants, educational tools, and any AI-integrated application Conclusion and Next Steps You've now seen how to integrate AI capabilities into a browser-based game using Microsoft Foundry Local. The Space Invaders project demonstrates that modern AI features don't require cloud services or complex infrastructure, they can run entirely on your laptop, responding in milliseconds. More importantly, you've learned patterns that extend far beyond gaming. The architecture of sending context to an AI, receiving generated responses, and integrating them into user experiences applies to countless applications: customer support bots, educational tutors, creative writing tools, and accessibility features. Your next step is experimentation. Clone the repository, modify the AI's personality, add new commentary triggers, or build an entirely new game using these patterns.

My A-Ha Moment Before watching this episode, setting up an AI development environment always felt like a challenge. There were so many moving parts—configurations, integrations, and dependencies—that it was hard to know where to begin. Seeing the AI Toolkit in action inside Visual Studio Code changed everything for me. It was a realization moment: “That’s it? I can explore models, test prompts, and deploy apps—without ever leaving my editor?” This episode made it clear that building with AI doesn’t have to be complex or intimidating. With the right tools, experimentation becomes faster and far more enjoyable. Now, I’m genuinely excited to build, test, and explore new generative AI solutions because the process finally feels accessible.

Modern SOC work is not limited by data—it’s limited by the friction of collecting it. This post shows a local-first workflow that lets you investigate Microsoft Sentinel incidents from inside VS Code using GitHub Copilot Chat for reasoning and a small, deterministic MCP toolset for evidence retrieval and (optionally) approval-gated writeback. What you’ll take away: How to structure a Copilot + MCP triage loop that stays grounded in Azure evidence A reliability pattern: fall back to KQL when Sentinel subresource APIs are flaky A safety pattern: draft-first, explicit-approval writeback for incident comments Why This Exists Sentinel triage is powerful but fragmented: you jump between the portal, KQL, entity pivots, and case notes just to answer “what happened?” The goal here is to collapse that into a single, repeatable loop inside the editor. Resolve the incident and pull the underlying alerts/entities Pivot into AzureActivity (and other logs) to identify the actor and outcome Use threat intelligence (TI) for context—not as the decision Generate an evidence-backed narrative and draft comment; write back only on explicit approval Design Principles Evidence first: every claim must be traceable to Sentinel APIs or Log Analytics results Small tool surface: fewer tools, clearer prompting, easier hardening Reliability by design: if one API path fails, pivot to KQL and continue Safety boundary: investigation and writeback are separate, and writeback is approval-gated Architecture & Data Flow A local TypeScript MCP server exposes a handful of triage tools to Copilot Chat in VS Code. Reads come from Sentinel + Log Analytics; writes (incident comments) are optional and require explicit approval. Copilot Chat (VS Code) decides the next step and summarizes outputs MCP server executes allowed tools: incident lookup, alert/entity retrieval, KQL queries, optional comment writeback Evidence sources: Sentinel Incident APIs + Log Analytics tables (SecurityIncident, SecurityAlert, AzureActivity, TI tables) Safety gate: writeback happens only after explicit approval; otherwise you get a draft Tool Surface MCP is useful here because it separates reasoning from execution: Copilot can decide what to do, but only the MCP server can do it—and only through tools you explicitly define and can audit. list_incidents / get_incident (ground the case) get_incident_alerts / get_incident_entities (fast path) run_incident_kql (reliable fallback + pivots) add_incident_comment (draft-first; writes only with approval) The Investigation Loop (3 Steps) Prompt used sentinel-triage-local Investigate Sentinel incident 1478 end to end in workspace Subscription ID/Resource Group/Workspace Name. Resolve the incident ID first, collect underlying alerts and entities, enrich with AzureActivity and TI, determine whether the activity is malicious or benign, and return: 1. Investigation summary 2. Key evidence 3. Entity analysis 4. TI enrichment result 5. Risk assessment 6. Recommended disposition 7. Final incident comment draft Rules: - Use tool output only, no guessing. - If alert/entity subresource APIs fail, pivot to KQL and continue. - Do not submit the comment unless I explicitly say: APPROVE COMMENT. 1) Ground the incident Resolve the human-friendly incident number to the Sentinel incident resource ID, then capture the metadata you need to drive every later pivot. Incident numbers are convenient for analysts, but the actual investigation flow depends on the underlying incident resource ID. Resolving that first gives the workflow a concrete anchor for: Title Severity Owner Status Alert count Analytic rule IDs Incident URL This gives you the stable identifiers (and the URL) needed to retrieve alerts, entities, and supporting logs. 2) Collect alerts and entities (fast path) Pull the alerts behind the incident and the entities they reference. When the incident subresource APIs behave, this is the fastest way to assemble the working set. In the ideal path, the agent can call the incident alert and entity subresources directly. That gives fast access to: Alert IDs Alert names Timestamps Severities Entities Provider metadata 3) Stay reliable: pivot to KQL when APIs fail In real environments, the incident subresource APIs for alerts/entities are not always dependable. When they fail, the workflow switches to Log Analytics and reconstructs the same evidence via KQL—so the investigation continues. SecurityIncident to recover the incident record and alert IDs SecurityAlert to retrieve alert details and entities AzureActivity to determine who or what performed the operation ThreatIntelligenceIndicator and ThreatIntelIndicators for enrichment The High-Signal Pivot: AzureActivity In the incidents I tested, AzureActivity was the fastest way to classify “suspicious deployment” alerts: it tells you who did the action, what operation ran, and whether it succeeded. The evidence showed: The caller was a single Microsoft Entra ID object ID Claims_d.idtyp = "app" Authorization_d.evidence.principalType = "ServicePrincipal" The activity was tied to a policy assignment The operation was MICROSOFT.RESOURCES/DEPLOYMENTS/WRITE The result was BadRequest with InvalidTemplate That pattern typically points to automation (service principal + policy-driven deployment) failing due to a bad template—not an interactive attacker. Threat Intelligence: Use It as Context Enrich observables against TI, but treat it as corroboration: a hit is not proof, and a miss is not a clean bill of health. In my test runs, TI mainly helped refine confidence after AzureActivity and alert evidence established the likely story. Output: An Evidence-Backed Narrative (and a Draft Comment) Once the tools return results, Copilot’s job is synthesis: turn structured evidence into a short narrative an analyst can paste into the case. What happened, who/what triggered it, and whether it succeeded Key supporting evidence (alerts, entities, AzureActivity pivots, TI context) A recommended disposition and a draft incident comment Incident comment written back automatically (after approval) (screenshot): Safety + Reliability: Approval-Gated Writeback The agent can draft a comment automatically, but it cannot change incident state unless the analyst explicitly approves. That boundary is what makes the workflow usable in real operations. After approval, the tool submits the drafted comment directly to the Sentinel incident so the portal reflects the same evidence-backed narrative. Default: return the draft comment only On approval: acquire an ARM token via Azure CLI and submit via curl.exe (hardened with validation + retries) Why This Is Worth Building Less context switching: investigation happens where you already work More consistency: the same loop runs every time, with deterministic tools Better classification: AzureActivity pivots reduce false “user did X” assumptions Safer automation: drafts are automatic; writes are explicit and auditable Conclusion AI is most useful in a SOC when it is constrained: deterministic tools fetch the evidence, the model synthesizes it, and humans keep control of state changes. A local Copilot + MCP workflow hits that sweet spot—faster triage for the SOC analysts.
