Keep version control state clean and deliberate — atomic commits with real messages, branch before risky work, never commit debris or secrets. Use when committing, branching, or at the start of any change large enough to want an undo point.

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.

Git is the safety net and the paper trail; sloppy use degrades both.
git log during an incident.git status and git diff before staging; git add -A is how debug scripts, .env files, editor droppings, and 40MB fixtures end up in history. Anything untracked that you didn't deliberately create gets investigated, not committed.git log -S symbol, git blame, and the message on the line you're about to change often explain the "weird" code — read it before "fixing" something a past commit did deliberately.git log --oneline -20 to see the house style before writing yours.Exit check before any commit: read the staged diff top to bottom (see self-review-diff) — the commit is the last cheap moment to catch what shouldn't ship.
