 Firstmate will then instruct you to run /no-mistakes to validate and ship a PR.

 Do not hand-edit, commit, or fix findings yourself while a run is active - the pipeline applies every fix.
 
 Two firstmate-specific rules layer on top of that guidance:
 - ask-user findings are never yours to answer: escalate to firstmate (rule 6) and stop.
-  Firstmate applies the authority contract in its \`AGENTS.md\` and obtains any required captain decision.
-  When the decision comes back, feed it to the gate with \`no-mistakes axi respond\` and let the pipeline apply it - do not route the question to "the user" or implement the fix yourself.
-- Avoid \`--yes\`: it would silently bypass firstmate's authority check and any required captain escalation.
