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.
