Detect a Copilot Studio agent's authentication mode (DirectLine vs M365) by querying Dataverse. Returns the mode and connection details needed to chat.

🔌 This skill ships inside the copilot-studio plugin — install the plugin and you also get 4 sub-agents, hooks.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

Detect Agent Authentication Mode

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).

Instructions

  1. Run the detect-only command:

    node ${CLAUDE_SKILL_DIR}/../../scripts/chat-with-agent.bundle.js --detect-only $ARGUMENTS

    If the agent is not at the project root, pass --agent-dir <path>.

  2. Parse the JSON output from stdout:

    DirectLine mode (authenticationmode 1 or 3)

    { "status": "ok", "mode": "directline", "authenticationmode": 1, "tokenEndpoint": "https://...", "schemaName": "..." }

    The agent uses no authentication or manual authentication. No user credentials needed. The tokenEndpoint is ready to use with /copilot-studio:chat-directline.

    M365 mode (authenticationmode 2)

    { "status": "ok", "mode": "m365", "authenticationmode": 2, "schemaName": "..." }

    The agent uses integrated authentication (Entra ID SSO). An App Registration Client ID is needed for /copilot-studio:chat-sdk.

  3. Return the result to the caller. Do not proceed to chat — that is a separate step.
