Shared loop-engineering reference for COG skills - the agent loop, deterministic verifiers, termination conditions, in-loop context management, and named patterns. Invoke when designing or debugging a skill that iterates (search-verify-retry, scan-until-dry, fetch-retry-gate).

Verify an RFC or design doc against the actual implementation — find drift, missing pieces, and undocumented changes. Trigger phrases include "verify the RFC", "compare design doc to implementation", "is the spec implemented", "does the code match the design", "what's drifted from the RFC", "audit the doc against", "spec compliance check", "is what we built what we designed".

Synthesize the user's own work activity, priorities, and recent context using Glean — use when the user asks about their recent work, what they accomplished, what is urgent, what needs their attention, or wants help with status updates, 1:1 prep, or weekly summaries.
