A signal-detector skill nominally fires on every chat turn — but only if the LLM is in a mode that actually executes the skill contract. During a focused build session shipping iOS code, the model treats the skill as documentation rather than as a contract, and capture silently never happens. This is a hidden failure mode that breaks ambient capture systems without producing any visible error.
