Run this before any\n  eval or SDK chat workflow. Requires an App Registration with MakerOperations\n  and Copilots.Invoke permissions.\nallowed-tools: Bash(node *eval-api.bundle.js auth *), Read, Glob\ncontext: fork\nagent: copilot-studio-test\n---\n\n# Test Agent Authentication\n\nAuthenticate with the Power Platform API for evaluation and SDK chat workflows.\nThis caches a token in the `\"test-agent\"` slot that is shared by `run-eval` and `chat-sdk`.\n\n## Step 1: Find the workspace\n\nLocate the agent workspace (directory containing `.mcs/conn.json`):\n```bash\nGlob: **/agent.mcs.yml\n```\n\nThe `conn.json` provides the tenant ID automatically — no need to ask the user for it.\n\n## Step 2: Get the client ID\n\n**CRITICAL: You MUST present the FULL configuration checklist below when asking for the client ID. Do NOT omit any items — users frequently miss the redirect URI and public client settings, which causes auth failures.**\n\nAsk the user for their **App Registration Client ID** and show them **all** of the following requirements in your message:\n\n> What is your App Registration Client ID for the Evaluation API?\n>\n> Before sharing it, please verify your App Registration has **all** of these settings:\n>\n> 1. **Redirect URI**: Under **Authentication** > **Mobile and desktop applications** > redirect URI set to `http://localhost`\n> 2. **Public client**: Under **Authentication** > **Advanced settings** > **Allow public client flows** set to **Yes**\n> 3. **API permissions**: Under **API permissions**, these **delegated** permissions on the **Power Platform API**:\n>    - `CopilotStudio.MakerOperations.Read` (list test sets, get results)\n>    - `CopilotStudio.MakerOperations.ReadWrite` (start evaluation runs)\n>    - `CopilotStudio.Copilots.Invoke` (SDK chat — send utterances to the agent)\n> 4. **Admin consent**: Granted for the tenant (green checkmarks in the API permissions list)\n>\n> Missing any of these will cause authentication to fail.\n\nIf the user doesn't have one, guide them:\n\n> **How to create an App Registration:**\n> 1. Go to [Azure Portal > App Registrations](https://portal.azure.com/#view/Microsoft_AAD_RegisteredApps/ApplicationsListBlade)\n> 2. Click **New registration**, name it (e.g., \"Copilot Studio Eval\")\n> 3. Under **API permissions** > **Add a permission** > **APIs my organization uses** > search **Power Platform API**\n> 4. Select **Delegated permissions** and add:\n>    - `CopilotStudio.MakerOperations.Read`\n>    - `CopilotStudio.MakerOperations.ReadWrite`\n>    - `CopilotStudio.Copilots.Invoke`\n> 5. Click **Grant admin consent** for the tenant\n> 6. Under **Authentication** > **Add a platform** > **Mobile and desktop applications** > set redirect URI to `http://localhost`\n> 7. Still in **Authentication**, scroll to **Advanced settings** and set **Allow public client flows** to **Yes** (required — without this the interactive browser login will fail with an AADSTS error)\n> 8. Copy the **Application (client) ID** from the Overview page\n\n## Step 3: Authenticate\n\nRun the auth command (opens a browser — no device code needed):\n\n```bash\nnode ${CLAUDE_SKILL_DIR}/../../scripts/eval-api.bundle.js auth --workspace \u003cpath> --client-id \u003cid>\n```\n\nIf successful, you'll see:\n```json\n{\"status\": \"ok\", \"message\": \"Authentication successful. Token cached for subsequent commands.\"}\n```\n\n**Return the client ID and workspace path to the caller** — they need these for subsequent `run-eval` and `chat-sdk` calls.\n\n## Troubleshooting\n\n- **HTTP 403 / InsufficientDelegatedPermissions**: The app registration is missing required permissions. Guide the user through adding them (Step 2).\n- **AADSTS700016 / app not found in directory**: The client ID doesn't exist in the agent's tenant. The app must be registered in the same tenant as the Copilot Studio environment (check `conn.json` > `AccountInfo.TenantId`).\n- **AADSTS7000218 / request body must contain client_secret or client_assertion**: The app registration is not configured as a public client. Go to **Authentication** > **Advanced settings** > set **Allow public client flows** to **Yes**.\n- **SDK chat hangs after auth**: The cached token may have stale permissions. Clear the cache and re-authenticate:\n  - Delete `~/.copilot-studio-cli/test-agent.cache.json`\n  - Run `security delete-generic-password -s \"copilot-studio-cli\" -a \"test-agent\"` to clear the macOS Keychain entry\n  - Re-run the auth command\n\n---\nSource: https://github.com/microsoft/skills-for-copilot-studio/blob/main/skills/test-auth/SKILL.md\nAuthor: Microsoft 365 Copilot (microsoft/skills-for-copilot-studio), licensed MIT.
