Polish your own diff by hand with KISS/DRY and local style — the pre-handoff pass, not a test run and not a subagent sweep. Use for /clean, "clean it up", "tidy this", and automatically before creating, updating, or automerging a PR or moving to the next one.
The general profile-driven perf loop for any language or runtime: baseline, profile, fix the real hot path, re-measure. Use for /perf, "this is slow", or optimization work.
Prove a visual change by looking at the rendered surface — screenshot it and compare to the reference before saying done. Use after any UI, layout, theme, or color change, or when the user says it still looks wrong or doesn't match.
Clear everything blocking an existing PR/MR from merging — rebase onto the default branch, get CI green, and resolve review threads (Copilot and human). Use for "rebase on main", "make CI green", "fix CI/CD", "address the reviews", "address Copilot", "review-loop", or "get this mergeable".
Maintainer triage on OTHER people's PRs/MRs — verdict of approve, supersede, or close, salvage with credit, close the cluster. Use for a review batch, a pasted Discord thread with a PR, or salvage/supersede/close asks. Not for your own PR (that's pr-ready).
Open a PR/MR if missing, or refresh an existing one's title and description so they match the current diff. Preserves any media already in the body. Use when the user says /pr-update, open a PR, update the PR, refresh the PR title/description, or wants the PR opener/manager flow.
Look it up before answering or building — this project's documents of record first, then external prior art. Use when the user says research, look it up, sleuth GitHub, "what do other people do", "is that a thing", "are you sure", or asks for something that has obviously been solved before.
Handle dependent/stacked PRs and same-code-on-multiple-bases correctly. Use for a PR stacked on another, or when the same change must land on the default branch plus a release/production branch.
