Microsoft Foundry Skill

This skill helps developers work with Microsoft Foundry resources, covering model discovery and deployment, complete dev lifecycle of AI agent, evaluation workflows, and troubleshooting.

Pre-Execution Requirements

MANDATORY: Before executing ANY workflow, you MUST first call the Azure MCP foundry tool and inspect the available Foundry MCP tools and related parameters. Treat this initial foundry call as a discovery/help step. For this skill, Azure MCP foundry is the required entry point for Foundry-related MCP operations.

Sub-Skills

MANDATORY: Before executing ANY workflow-specific steps, you MUST read the corresponding sub-skill document. Do not call workflow-specific MCP tools for a workflow without reading its skill document. This applies even if you already know the MCP tool parameters — the skill document contains required workflow steps, pre-checks, and validation logic that must be followed. This rule applies on every new user message that triggers a different workflow, even if the skill is already loaded.

This skill includes specialized sub-skills for specific workflows. Use these instead of the main skill when they match your task:

Sub-Skill	When to Use	Reference
deploy	Containerize, build, push to ACR, create/update/clone agent deployments	deploy
invoke	Send messages to an agent, single or multi-turn conversations	invoke
invocations-ws	Build, deploy, and connect to hosted agents that speak the invocations_ws duplex WebSocket protocol — voice agents, real-time streams, and signaling for out-of-band media transports.	invocations-ws
observe	Evaluate agent quality, run batch evals, analyze failures, optimize prompts, improve agent instructions, compare versions, set up CI/CD monitoring, and enable continuous production evaluation	observe
trace	Query traces, analyze latency/failures, correlate eval results to specific responses via App Insights customEvents	trace
troubleshoot	View hosted agent logs, query telemetry, diagnose failures	troubleshoot
create	Create new hosted agent applications. Supports Microsoft Agent Framework, LangGraph, or custom frameworks in Python or C#, across responses, invocations, or invocations_ws protocols.	create
agent-optimizer	Make existing Python hosted-agent code optimization-ready, configure eval.yaml, run Agent Optimizer jobs, apply candidates locally, and deploy through azd after review.	agent-optimizer
eval-datasets	Harvest production traces into evaluation datasets, manage dataset versions and splits, track evaluation metrics over time, detect regressions, and maintain full lineage from trace to deployment. Use for: create dataset from traces, dataset versioning, evaluation trending, regression detection, dataset comparison, eval lineage.

💡 Tip: For a complete onboarding flow: project/create (public) or private-network (VNet isolation) → models/deploy-model → agent workflows (create → deploy → invoke).

💡 Fine-Tuning: Use finetuning for all model customization — SFT distillation, DPO preference optimization, and RFT with graders. Includes quickstart, grader calibration, and training curve analysis.

💡 Model Deployment: Use models/deploy-model for all deployment scenarios — it intelligently routes between quick preset deployment, customized deployment with full control, and capacity discovery across regions.

💡 Prompt Optimization: For requests like "optimize my prompt" or "improve my agent instructions," load observe and use the prompt_optimize MCP tool through that eval-driven workflow.

Infrastructure Lifecycle

Match user intent to the correct infrastructure workflow.

User Intent	Workflow
"Create Foundry" / "Set up Foundry" (ambiguous)	Use AskUserQuestion: (a) just an AI Services resource, (b) a project with public access, or (c) a project with network isolation? Route: (a) → resource/create, (b) → project/create, (c) → private-network
Set up Foundry with VNet isolation	private-network
Create a Foundry project (public)	project/create
Create a bare Foundry resource	resource/create

Agent Development Lifecycle

Match user intent to the correct agent workflow. Read each sub-skill in order before executing.

User Intent	Workflow (read in order)
Create a new agent from scratch	create → deploy → invoke
Optimize existing Python hosted agent	agent-optimizer → scaffold/review → eval.yaml → optimize → apply candidate → deploy → invoke
Deploy an agent (code already exists)	deploy (includes eval-suite setup) → invoke → observe (evaluate/optimize)

Agent: .foundry Workspace Standard

Every agent source folder can keep Foundry-specific cache and overlay state under .foundry/:

<agent-root>/
  .foundry/
    agent-metadata.yaml
    agent-metadata.prod.yaml
    suites/
    datasets/
    evaluators/
    results/

• In azd projects, derive deployment context (project endpoint, agent name/version, ACR, App Insights) from azure.yaml plus azd env get-values; do not duplicate those values in metadata when azd already provides them.
• agent-metadata.yaml is the preferred local/dev overlay for non-azd values, remote Foundry suite references, local cache paths, result summaries, and explicit overrides. Optional sidecar files such as agent-metadata.prod.yaml can hold a single prod or CI-targeted overlay without mixing multiple environments in one file.
• suites/, datasets/, and evaluators/ are local cache folders. Reuse them when they are current, and ask before refreshing or overwriting them.
• See Agent Metadata Contract for the canonical schema and workflow rules.

Agent: Common Project Context Resolution

Agent skills should run this step only when they need configuration values they don't already have. If a value (for example, agent root, environment, project endpoint, or agent name) is already known from the user's message or a previous skill in the same session, skip resolution for that value.

Step 1: Discover Agent Roots and azd Context

First check whether the workspace has azure.yaml with services using host: azure.ai.agent.

• One azd agent service -> use that service's project folder as the agent root.
• Multiple azd agent services -> require the user to choose the target service/folder.
• No azd agent service -> search the workspace for .foundry/ folders that contain agent-metadata.yaml or agent-metadata.<env>.yaml.
  • One match -> use that agent root.
  • Multiple matches -> require the user to choose the target agent folder.
  • No matches -> for create/deploy workflows, seed a new .foundry/ folder during setup; for all other workflows, stop and ask the user which agent source folder to initialize.

After selecting an agent root, keep all local .foundry cache inspection, source inspection, evaluator suggestions, dataset suggestions, and prompt-optimization context inside that folder only. Do not scan sibling agent folders unless the user explicitly switches roots.

Step 2: Resolve Environment and Deployment Context

If azure.yaml is present, resolve the azd environment first:

1. Environment explicitly named by the user
2. AZURE_ENV_NAME from azd env get-values
3. azd default environment from .azure/config.json
4. Environment already selected earlier in the session

Run azd env get-values for the selected environment when project/deployment values are not already known. Prefer azd values for deployment context:

azd Variable	Resolves To
AZURE_AI_PROJECT_ENDPOINT or AZURE_AIPROJECT_ENDPOINT	Project endpoint
AGENT_<SERVICE>_NAME	Agent name for the selected azd service
AGENT_<SERVICE>_VERSION	Agent version for the selected azd service
AZURE_CONTAINER_REGISTRY_NAME or AZURE_CONTAINER_REGISTRY_ENDPOINT	ACR registry name / image URL prefix
APPLICATIONINSIGHTS_CONNECTION_STRING	App Insights connection string for trace workflows
AZURE_SUBSCRIPTION_ID, AZURE_RESOURCE_GROUP, AZURE_AI_ACCOUNT_NAME, AZURE_AI_PROJECT_NAME	Azure resource lookup and Playground links

When azd supplies these values, use them as the source of truth and do not copy them into .foundry/agent-metadata*.yaml on metadata writes.

Step 3: Select Metadata Overlay and Resolve Environment

Inside the selected agent root, choose the metadata file in this order:

1. Metadata filename or path explicitly provided by the user or workflow
2. If an explicit environment is already known and .foundry/agent-metadata.<env>.yaml exists, use that file
3. .foundry/agent-metadata.yaml
4. If multiple metadata files remain and no rule above selects one, prompt the user to choose

Read the selected metadata file and resolve any remaining environment choice in this order:

1. Environment explicitly named by the user
2. If the selected metadata file defines exactly one environment, use it
3. Environment already selected earlier in the session
4. defaultEnvironment from metadata

If the selected metadata file still contains multiple environments and none of the rules above selects one, prompt the user to choose. Keep the selected agent root, metadata file, environment, and whether context came from azd or metadata visible in every workflow summary.

If the selected environment exposes older testSuites[] metadata but not evaluationSuites[], treat testSuites[] as the source for this session and normalize each entry in memory to the evaluationSuites[] shape before continuing. If the metadata is older still and only exposes legacy testCases[], normalize that list the same way. Preserve dataset and evaluator fields, keep any existing tags, and map legacy priority to tags.tier only when tags.tier is missing: P0 -> smoke, P1 -> regression, P2 -> coverage.

Step 4: Resolve eval.yaml Local Evaluation Intent

If eval.yaml exists in the selected agent root, parse it before generating new suites:

• agent.name -> target agent candidate; verify it matches the selected azd/metadata agent before using it.
• dataset_file -> local seed dataset candidate.
• evaluators[] -> candidate Foundry evaluator names; verify with evaluator_catalog_get before treating them as remote evaluators.
• name -> local eval/suite candidate; verify remotely before persisting as suiteName.
• options.eval_model, options.pass_threshold, max_samples, trace_days, and generation_instruction -> setup defaults.

Treat eval.yaml as local evaluation intent, not proof that a Foundry suite exists. Persist synced suite/dataset/evaluator references to .foundry only after remote lookup or registration succeeds.

Step 5: Resolve Common Configuration

Layer sources in this order:

1. Explicit user input and values already selected in the session
2. azd environment values for deployment context
3. .foundry/agent-metadata*.yaml overlay values and remote suite/cache references
4. agent.yaml and eval.yaml local source configuration
5. User prompts for anything still missing

If azd and metadata both provide the same value and they differ, stop and ask which source is authoritative. If they match, use the azd value and avoid rewriting the duplicate on future metadata writes.

Effective Value	Preferred Source	Used By
Project endpoint	azd env	deploy, invoke, observe, trace, troubleshoot
Agent name/version	azd agent variables, then agent.yaml	invoke, observe, trace, troubleshoot
ACR	azd env	deploy
Evaluation suites and cache paths	.foundry/agent-metadata*.yaml	observe, eval-datasets
Local seed dataset/evaluator intent	eval.yaml	observe, eval-datasets

Step 6: Write Metadata Overlay (Create/Deploy/Observe Only)

On any metadata write (deploy, auto-setup, dataset refresh, or trace-to-dataset update), persist only non-derivable overlay/cache state in the selected metadata file:

• azd binding (azd.environmentName, azd.service) when useful for future resolution
• evaluationSuites[] with remote suite/dataset/evaluator references and local cache paths
• lastEval, result files, comparison summaries, or explicit non-azd overrides

Do not copy azd-owned deployment values into metadata when azd already provides them. If the selected file is a preferred single-environment file, rewrite only that one environment block. If the selected file is a legacy multi-environment file, rewrite only the selected environment block. Never copy or merge environments across sibling metadata files automatically. If the selected environment still uses older testSuites[] or legacy testCases[], rewrite it to evaluationSuites[] and remove migrated priority fields from the rewritten entries.

Step 7: Collect Missing Values

Use the ask_user or askQuestions tool only for values not resolved from the user's message, session context, metadata, or azd bootstrap. Common values skills may need:

• Agent root — Target azd service project folder or folder containing .foundry/agent-metadata*.yaml
• Metadata file — agent-metadata.yaml for local/dev, or an explicit sidecar such as agent-metadata.prod.yaml
• Environment — azd environment, dev, prod, or another environment key from metadata
• Project endpoint — AI Foundry project endpoint URL
• Agent name — Name of the target agent

💡 Tip: If the user already provides the agent path, environment, project endpoint, or agent name, extract it directly — do not ask again.

Agent: Agent Types

All agent skills support two agent types:

Type	Kind	Description
Prompt	"prompt"	LLM-based agents backed by a model deployment
Hosted	"hosted"	Container-based agents running custom code

Use agent_get MCP tool to determine an agent's type when needed.

Tool Usage Conventions

• Use the ask_user or askQuestions tool whenever collecting information from the user
• Use the task or runSubagent tool to delegate long-running or independent sub-tasks (e.g., env var scanning, status polling, Dockerfile generation)
• Prefer Azure MCP tools over direct CLI commands when available
• Reference official Microsoft documentation URLs instead of embedding CLI command syntax
