markChecklistComplete

Record that the pilot finished a checklist — the Copilot’s first action that WRITES to your account. Call only after walking through every item and getting your confirmation; it logs a completion record with the elapsed time. Ownership is verified before any write, and a retried call within seconds is de-duplicated rather than double-logged.

ProblemWhat it solves

The problem this tool solves

Confirming a checklist out loud is easy; capturing that it was actually completed is what builds a record. This logs a completion against YOUR checklist only — it refuses an id you do not own (IDOR guard), collapses an accidental double-tap into one entry, and adds no extra metering beyond the chat turn already in progress.

Example interaction

Pilot asks

I’ve finished the run-up — log it, that took about three minutes.

Copilot responds

Recorded completion of “Run-Up (C172)” — duration 180 s. (If the same completion is sent twice within ~10 seconds it is de-duplicated; a checklist you do not own is refused rather than written.)
