Creating, refining, splitting, consolidating, renaming, or auditing an agent skill — drafting a `SKILL.md`, editing frontmatter, tightening a `description`, deciding where a new rule belongs, or running the structure validators. Triggers on "add a skill",…
Writing, refactoring, or reviewing code for maintainability or design — "readable", "too long", "refactor", "abstraction", "cohesion", "magic number", "dead code", "what should this be called", or "should this live elsewhere". Cohesion as the test of what…
Writing, reviewing, refactoring, or running end-to-end tests, or verifying a change through the e2e suite — including a prompt naming only snapshots, test IDs, selectors or locators, polling and waiting, flaky tests, scenario coverage, a runner (Playwright,…
Driving a code change or document update end-to-end through the plan → code → review loop — "deliver this issue", "implement and open a PR for X", a free-form change request, or resuming an in-progress run — as the project's default change loop. Apply even…
Reviewing whether a change carries adequate verification evidence — "is this verified", "did this break anything", "were the required checks run". The reviewer's QA pass on top of the development verification rules. Covers requiring command evidence for the…
Building or reviewing a React component — "props", "spread props", "compound component", "variant prop", "empty state", "error state", "skeleton", "data-testid", "testID", "extract a hook", "useEffect", "where state lives", "memo", "virtualize", "FlatList",…

Every task that touches a project — implementing, refactoring, running a project command, or writing a pull request body — even when the request never mentions formatting, linting, comments, dependencies, docs, or descriptions. Also when you need to know how…
Writing, reviewing, or modifying code that logs, throws, catches, reports an error, tracks a product event, identifies a user, or configures a logger, error tracker, tracing, or analytics tool — including a request naming only "logging", "log level", "capture…
Drafting, structuring, editing, or reviewing a technical document — a design doc, RFC, ADR, runbook, README, API reference, changelog, or post-mortem. Triggers on "make this clearer", "how should I structure this", "is this readable", "too wordy", "passive…
Producing a low-fidelity wireframe, breadboard, or wireflow of any client-app UI, mobile or web — sketching screens, breadboarding a flow, comparing layout options, annotating intent, or the wireframe round of a design review. Not for high-fidelity real-token…
Deciding whether material belongs in a skill at all, or in the project's own documentation instead, before deciding its tier; adding, editing, renaming, moving, or removing an agent skill in a project that keeps skills in two tiers; a `git status` showing…
Reviewing a code change — a pull request, a branch or commit-range diff, or a post-implementation self-review of your own work before calling it done. Not for writing the change, only for judging one that already exists. Covers the reviewer-mode reset and…
Updating a project's own documentation when a change alters what it says, and reading it before planning one — a behaviour, a domain term, or a decision that constrains future work; also placing or updating a project's conventions or operational procedures…
Apply this in every session — answering a question, investigating, reviewing, or building. Triggers on any uncertainty about facts, scope, or intent; on "are you sure", "don't guess", "what's the latest"; before asserting a version, API, price, or date;…

Authoring or revising a Git commit message, titling a pull request, or judging whether a header conforms — "write a commit message", "what type should this be", "is this header valid", "does this need a scope", "mark this as a breaking change", or preparing a…
Reading from or writing to GitHub from inside an agent session acting as one connected operator — any issue, pull request, comment, label, review, or branch operation, not only end-to-end change loops. Covers the default sanctioned tool channel, when another…
