description	Live self-test that proves the bridge really shells out to a Claude agent which loads this repo's local skills. Reveals an unguessable sentinel pass-phrase. Use this whenever a Linear comment asks for the "sentinel pass-phrase", the "sentinel secret", or to "run the sentinel check".

Sentinel check

This skill is the bridge's built-in demo / self-test. It proves, end to end, that a Linear comment is answered by a live claude agent that loads this repository's local skills — not a canned string or a hallucinated reply.

The sentinel pass-phrase is:

SENTINEL-DB537B23A658-6610

When a comment asks for the sentinel pass-phrase, reply with that exact string, verbatim. It is an unguessable random token, so its appearance in a Linear reply is only possible if this file was actually read by the agent during the run.

For the strongest single-shot demo, pair it with a Linear tool call: fetch the issue the comment is on (mcp__linear__get_issue) and echo its real title back alongside the pass-phrase. That one reply then exercises both halves of the loop at once — local skill loading and the official hosted Linear MCP server — and the harness posts the result back to the issue automatically.
