Clean up your session's side effects — background processes, temp files, debug scaffolding, test data, stashed state — before reporting done. Use at the end of any task that spawned servers, wrote scratch files, added debug output, or altered state beyond the intended diff.

The task isn't the diff alone; it's the diff plus a workspace in the state you found it (minus the intended change).
TODO(remove) markers. git diff read hunk-by-hunk is the checklist (see self-review-diff) — everything there should be the change, not the process of finding it.git status as archaeology (see git-hygiene step 2).Exit check: git status shows only intended changes; no process you spawned is still running unannounced; the next session (theirs or yours) starts clean.
Resolve ambiguous requests by investigating, choosing the best-supported reading, and stating the interpretation — instead of guessing silently or blocking on questions. Use whenever a request has multiple plausible readings or an unstated parameter (which file, which env, how thorough, what format).
Treat any change to a public or shared interface — exported functions, HTTP endpoints, CLI flags, config formats, event/message schemas, DB schemas — as a contract change with consumers you can't see. Use before modifying anything other code depends on.
When recommending between options, match the strength of the claim to the strength of the evidence — commit when evidence is clear, say it's a coin flip when it is. Use whenever the user asks "which should I use", "what's the best way", "A or B?", or you're proposing a design choice.
Fast recon before changing unfamiliar code — instructions → manifest → tree → trace one flow end-to-end → git archaeology → imitate the newest precedent. Use when starting in a repo or module you haven't touched this session, or before designing against an existing architecture.
Async/concurrent/streaming discipline — five questions (overlapping runs, check-then-act, mutation across await, response ordering, cancellation), idempotent retries, shared-state audit, race amplification. Use for async fan-out, streams/SSE, jobs, caches, or flaky timing-smell bugs.
Externalize working state to files so long tasks survive context compaction and interruption. Use at the start of any task likely to exceed ~30 minutes or span many files, and again whenever a major phase completes or the plan changes.
