$npx -y skills add microsoft/skills-for-copilot-studio --skill detect-modeDetect a Copilot Studio agent's authentication mode (DirectLine vs M365) by querying Dataverse. Returns the mode and connection details needed to chat.
| 1 | # Detect Agent Authentication Mode |
| 2 | |
| 3 | Query the Dataverse `bots` entity to determine whether the agent uses DirectLine (no auth / manual auth) or the Copilot Studio SDK (integrated auth / Entra ID SSO). |
| 4 | |
| 5 | ## Instructions |
| 6 | |
| 7 | 1. Run the detect-only command: |
| 8 | |
| 9 | ```bash |
| 10 | node ${CLAUDE_SKILL_DIR}/../../scripts/chat-with-agent.bundle.js --detect-only $ARGUMENTS |
| 11 | ``` |
| 12 | |
| 13 | If the agent is not at the project root, pass `--agent-dir <path>`. |
| 14 | |
| 15 | 2. Parse the JSON output from stdout: |
| 16 | |
| 17 | ### DirectLine mode (authenticationmode 1 or 3) |
| 18 | ```json |
| 19 | { "status": "ok", "mode": "directline", "authenticationmode": 1, "tokenEndpoint": "https://...", "schemaName": "..." } |
| 20 | ``` |
| 21 | The agent uses **no authentication** or **manual authentication**. No user credentials needed. The `tokenEndpoint` is ready to use with `/copilot-studio:chat-directline`. |
| 22 | |
| 23 | ### M365 mode (authenticationmode 2) |
| 24 | ```json |
| 25 | { "status": "ok", "mode": "m365", "authenticationmode": 2, "schemaName": "..." } |
| 26 | ``` |
| 27 | The agent uses **integrated authentication (Entra ID SSO)**. An App Registration Client ID is needed for `/copilot-studio:chat-sdk`. |
| 28 | |
| 29 | 3. Return the result to the caller. Do not proceed to chat — that is a separate step. |

| 31 | ## Error Handling |
| 32 | |
| 33 | | Error | Cause | Resolution | |
| 34 | |-------|-------|------------| |
| 35 | | `No agent.mcs.yml found` | No agent in workspace | Clone the agent first | |
| 36 | | `No .mcs/conn.json found` | Agent not cloned via VS Code extension | Clone with the extension | |
| 37 | | `Could not detect authentication mode` | No cached Dataverse token | Run a push/pull first to cache tokens, or ask the user about their auth config | |
