Send a message to a Copilot Studio agent via the Copilot Studio Client SDK (M365). Use for agents with integrated auth (Entra ID SSO). Requires an App Registration Client ID.

Send a single utterance to a published agent via the Copilot Studio Client SDK. Use this for agents with integrated authentication / Entra ID SSO (authenticationmode 2).
Requires prior authentication via /copilot-studio:test-auth. Do NOT ask the user for a client ID yourself — the test-auth skill handles app registration setup and authentication.
--client-id and the utterance from $ARGUMENTS: node ${CLAUDE_SKILL_DIR}/../../scripts/chat-with-agent.bundle.js \
--client-id "<clientId>" "<utterance>" [--agent-dir <path>]
/copilot-studio:test-auth. The token is cached in the "test-agent" slot and shared with the eval API. If auth fails or the SDK hangs, tell the caller to re-run test-auth.{
"status": "ok",
"protocol": "m365",
"utterance": "hello",
"conversation_id": "abc123-...",
"start_activities": [ ... ],
"activities": [ ... ]
}
Display the agent's response from the activities array:
type === "message" — show textsuggestedActions.actions arrayattachments with contentType === "application/vnd.microsoft.card.adaptive"Save conversation_id for follow-ups.
Pass --conversation-id from the previous response:
node ${CLAUDE_SKILL_DIR}/../../scripts/chat-with-agent.bundle.js \
--client-id "<id>" "<follow-up>" --conversation-id "<id>"
SDK sessions do not expire as quickly as DirectLine. Reuse conversation_id automatically for follow-ups.
| Error | Cause | Resolution |
|-------|-------|------------|
| Authentication failed | Wrong client ID or tenant | Verify app registration and permissions |
| Could not obtain conversation_id | Agent not published or wrong config | Verify agent is published |
Take microsoft/chat-sdk from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
