+# Foundry Agent Sync
+
+## Overview
+
+Create and synchronize prompt-based AI agents directly within Azure AI Foundry via the Agent Service REST API. This skill registers agents in the Foundry service itself — making them immediately available for invocation, evaluation, and management through the Foundry portal or API. Each agent is created or updated idempotently via a named POST call, using definitions from a local JSON manifest file.
+
+> **Key distinction:** This skill creates agents inside AI Foundry (server-side). It does not scaffold local agent code or container images — for that, use the `microsoft-foundry` skill's `create` sub-skill.
+
+## Prerequisites
+
+The user must have:
+
+1. An Azure AI Foundry project with a deployed model (e.g. `gpt-5-4`)
+2. Azure CLI (`az`) authenticated with access to the Foundry project
+3. The **Azure AI User** role (or higher) on the Foundry project resource
+
+Collect these values before proceeding:
+
+| Value | How to get it |
+|---|---|
+| **Foundry project endpoint** | Azure Portal → AI Foundry project → Overview → Endpoint, or `az resource show` |
+| **Subscription ID** | `az account show --query id -o tsv` |
+| **Model deployment name** | The model name deployed in the Foundry project (e.g. `gpt-5-4`) |
+
+## Manifest Format
+
+The manifest is a JSON array where each entry defines one agent. Look for it at common paths: `infra/foundry-agents.json`, `foundry-agents.json`, or `.foundry/agents.json`. If none exists, scaffold one.
+
+```json
+[
+ {
+ "useCaseId": "alert-triage",
+ "description": "Short description of what this agent does.",
+ "baseInstruction": "You are an assistant that... "
+ }
+]
+```
+
+### Field Reference
+
+| Field | Required | Description |
+|---|---|---|
+| `useCaseId` | Yes | Kebab-case identifier; used to build the agent name (`{prefix}-{useCaseId}`) |
+| `description` | Yes | Human-readable description stored as agent metadata |
+| `baseInstruction` | Yes | System prompt / base instructions for the agent |
+
+## Sync Script
+
+### PowerShell (interactive / CI)
+
+Create or locate the sync script. The canonical path is `infra/scripts/sync-foundry-agents.ps1` but adapt to the repo layout.
+
+```powershell
+param(
+ [Parameter(Mandatory)]
+ [string]$SubscriptionId,
+
+ [Parameter(Mandatory)]
+ [string]$ProjectEndpoint,
+
+ [string]$ManifestPath = (Join-Path $PSScriptRoot '..\foundry-agents.json'),
+ [string]$ModelName = 'gpt-5-4',
+ [string]$AgentNamePrefix = 'myproject',
+ [string]$ApiVersion = '2025-11-15-preview'
+)
+
+$ErrorActionPreference = 'Stop'
+
+# Optional: append a common instruction suffix to every agent
+$commonSuffix = ''
+
+az account set --subscription $SubscriptionId | Out-Null
+$accessToken = az account get-access-token --resource https://ai.azure.com/ --query accessToken -o tsv
+if (-not $accessToken) { throw 'Failed to acquire Foundry access token.' }
+
+$definitions = Get-Content -Raw -Path $ManifestPath | ConvertFrom-Json
+$headers = @{ Authorization = "Bearer $accessToken" }
+$results = @()
+
+foreach ($def in $definitions) {
+ $agentName = "$AgentNamePrefix-$($def.useCaseId)"
+ $instructions = if ($commonSuffix) { "$($def.baseInstruction)`n`n$commonSuffix" } else { $def.baseInstruction }
+ $body = @{
+ definition = @{ kind = 'prompt'; model = $ModelName; instructions = $instructions }
+ description = $def.description
+ metadata = @{ useCaseId = $def.useCaseId; managedBy = 'foundry-agent-sync' }
+ } | ConvertTo-Json -Depth 8
+
+ $uri = "$($ProjectEndpoint.TrimEnd('/'))/agents/$agentName`?api-version=$ApiVersion"
+ $resp = Invoke-RestMethod -Method Post -Uri $uri -Headers $headers -ContentType 'application/json' -Body $body
+ $version = $resp.version ?? $resp.latest_version ?? $resp.id ?? 'unknown'
+ Write-Host "Synced $agentName ($version)"
+ $results += [pscustomobject]@{ name = $agentName; version = $version }
+}
+
+$results | Format-Table -AutoSize
+```
+
+### Bash (Bicep deployment script / CI)
+
+For automated deployment via `Microsoft.Resources/deploymentScripts`, use a bash script that:
+
+1. Authenticates with a managed identity: `az login --identity --username "$CLIENT_ID"`
+2. Acquires a Foundry token: `az account get-access-token --resource https://ai.azure.com/`
+3. Iterates definitions from the `FOUNDRY_AGENT_DEFINITIONS` environment variable (JSON string)
+4. POSTs each agent to `{endpoint}/agents/{name}?api-version=2025-11-15-preview`
+
+## Bicep Integration (optional)
+
+To run the sync automatically during infrastructure deployment:
+
+1. **Load the manifest** at compile time:
+ ```bicep
+ var agentDefinitions = loadJsonContent('foundry-agents.json')
+ ```
+
+2. **Create a User-Assigned Managed Identity** with the **Azure AI User** role on the Foundry project.
+
+3. **Create a `Microsoft.Resources/deploymentScripts`** resource (kind `AzureCLI`) that:
+ - Uses the managed identity
+ - Loads the bash sync script via `loadTextContent`
+ - Passes the project endpoint, definitions, and model as environment variables
+
+Gate behind a `deployFoundryAgents` parameter so teams can opt in/out.
+
+## Workflow
+
+### Step 1 — Locate or scaffold the manifest
+
+Search the repo for `foundry-agents.json`. If it doesn't exist, ask the user what agents they need and create the manifest.
+
+### Step 2 — Locate or scaffold the sync script
+
+Search for `sync-foundry-agents.ps1` or `foundry-agent-sync.sh`. If missing, create the PowerShell script using the template above, adapting:
+- `$AgentNamePrefix` to match the project name
+- `$ModelName` to the user's deployed model
+- `$ManifestPath` to the actual manifest location
+
+### Step 3 — Collect parameters
+
+Ask the user for:
+- Foundry project endpoint
+- Subscription ID
+- Model deployment name (default: `gpt-5-4`)
+- Agent name prefix (default: repo name in kebab-case)
+
+### Step 4 — Run the sync
+
+Execute the PowerShell script with the collected parameters:
+
+```powershell
+.\infra\scripts\sync-foundry-agents.ps1 `
+ -SubscriptionId '' `
+ -ProjectEndpoint '' `
+ -ModelName '' `
+ -AgentNamePrefix ''
+```
+
+### Step 5 — Verify
+
+Confirm synced agents by listing them:
+
+```powershell
+$token = az account get-access-token --resource https://ai.azure.com/ --query accessToken -o tsv
+$endpoint = ''
+Invoke-RestMethod -Uri "$endpoint/agents?api-version=2025-11-15-preview" `
+ -Headers @{ Authorization = "Bearer $token" }
+```
+
+## REST API Reference
+
+| Operation | Method | URL |
+|---|---|---|
+| Create/update agent | POST | `{projectEndpoint}/agents/{agentName}?api-version=2025-11-15-preview` |
+| List agents | GET | `{projectEndpoint}/agents?api-version=2025-11-15-preview` |
+| Get agent | GET | `{projectEndpoint}/agents/{agentName}?api-version=2025-11-15-preview` |
+| Delete agent | DELETE | `{projectEndpoint}/agents/{agentName}?api-version=2025-11-15-preview` |
+
+### Create/Update Payload
+
+```json
+{
+ "definition": {
+ "kind": "prompt",
+ "model": "",
+ "instructions": ""
+ },
+ "description": "",
+ "metadata": {
+ "useCaseId": "",
+ "managedBy": "foundry-agent-sync"
+ }
+}
+```
+
+## Troubleshooting
+
+| Symptom | Cause | Fix |
+|---|---|---|
+| `401 Unauthorized` | Token expired or wrong audience | Re-run `az account get-access-token --resource https://ai.azure.com/` |
+| `403 Forbidden` | Missing Azure AI User role | Assign the role on the Foundry project scope |
+| `404 Not Found` | Wrong project endpoint | Verify endpoint includes `/api/projects/{projectName}` |
+| Model not found | Model not deployed in project | Deploy the model in AI Foundry portal first |
+| Empty definitions | Manifest path wrong | Check `-ManifestPath` points to the JSON file |
