In source frontmatter, use clear kebab-case names and concise descriptions. There is no dedicated formatter or linter configured here, so match surrounding code closely. ## Testing Guidelines Tests use Bun’s test runner plus Node’s built-in `--test`. Name tests `*.test.js` or `*.test.mjs` and place new fixtures near the behavior they cover, usually under `tests/fixtures/`. Prefer targeted test runs while iterating, then finish with `bun run test`. If you change generated outputs or provider transforms, verify both source parsing and at least one affected provider path in `dist/`. -For changes to `skill/scripts/live-*.{mjs,js}` or `skill/scripts/live/**`, also run `bun run test:live-e2e` (kept out of the default suite because it does real `npm install` per fixture and boots framework dev servers).

Set `IMPECCABLE_E2E_AGENT=llm` to swap the deterministic fake agent for an API-backed one (`tests/live-e2e/agents/llm-agent.mjs`). Claude Haiku 4.5 is the primary path whenever `ANTHROPIC_API_KEY` is set.

It feeds the CLI, the site overlay (`cli/engine/detect-antipatterns-browser.js`, regenerated by `bun run build:browser`), the Chrome extension (`extension/detector/`, regenerated by `bun run build:extension`), and the homepage `DETECTION_COUNT` in `site/public/js/generated/counts.js` (regenerated by `bun run build`). After any rule change run all three builds plus `bun run test` so nothing drifts. - -TDD order is non-negotiable: - -1. Add a fixture at `tests/fixtures/antipatterns/{rule-id}.html` with two columns (should-flag / should-pass), each case identified by a unique heading. ≥4 flag cases and ≥5 false-positive shapes. **Use explicit pixel dimensions in CSS** — jsdom does no layout. -2. Add a failing test in `tests/detect-antipatterns-fixtures.test.mjs` using the snippet-substring pattern (regex `/"([^"]+)"/` against `SHOULD_FLAG` / `SHOULD_PASS` lists). -3. Add the rule entry to the `ANTIPATTERNS` array (`id`, `category` = `slop` or `quality`, `name`, `description`, optional `skillSection` / `skillGuideline`). -4. Implement a pure `checkXxx(opts)` returning `[{ id, snippet }]` — no DOM access inside. -5. Add two adapters that wrap the pure check: `checkElementXxxDOM(el)` for the browser (`getComputedStyle` + `getBoundingClientRect`) and `checkElementXxx(el, tag, window)` for jsdom (`parseFloat(style.width)` instead of layout). Wire **both** adapters into **both** element loops in `cli/engine/detect-antipatterns.mjs` (browser loop ~line 1837, jsdom loop in `detectHtml` ~line 2058). Forgetting one is the most common mistake. -6. Verify on a live page at `http://localhost:4321/fixtures/antipatterns/{rule-id}.html` and on the homepage. The two adapter paths can disagree. - -Conventions: wrap the identifying heading text in straight double quotes inside snippets so the fixture test can extract it. jsdom-specific helpers `resolveBackground()`, `resolveGradientStops()`, and `parseGradientColors()` exist because `background:` shorthand isn't decomposed and computed colors aren't normalized in jsdom — use them. Reference rules to copy from: `side-tab` (border), `low-contrast` (color+gradient), `icon-tile-stack` (sibling relationship), `flat-type-hierarchy` (page-level). +The rule engine lives in the engine repo, not here. What this repo owns is the behavior contract: `docs/CLI-CONTRACT.md` describes every verb, `tests/oracle/` holds the recorded goldens and replays them against the binary (`tests/oracle.test.mjs`), and `tests/fixtures/antipatterns/*.html` are the fixtures those goldens scan. A rule change lands in the engine, then here as a new oracle case (`node tests/oracle/record.mjs --bin `, golden reviewed by hand) and, when it introduces new design guidance, an edit to `skill/SKILL.src.md` or `skill/reference/*.md`. Rule counts quoted in `README.md` and `README.npm.md` are checked by the build against `extension/detector/antipatterns.json` when that vendored file is present. ## Commit & Pull Request Guidelines @@ -88,4 +77,4 @@ Tags are per-component because the three components ship independently: `skill-v ## Contributor Notes -Do not edit generated provider files directly unless you are intentionally patching generated output as part of a build-system change.

This is the only check that catches loader-contract surprises the unit guards can't know about (PR #494 shipped an `agents` manifest key that silently loaded zero agents; `claude plugin validate` never flags plugin-manifest problems). Runs in about a second; skips cleanly when the `claude` CLI is not on PATH.

Never add a key to the generated plugin manifest without verifying it against a real install and extending `KNOWN_LOADER_KEYS`. **Important:** `tests/build.test.js` uses `spyOn(transformers, 'transformCursor')` with the named exports from `scripts/lib/transformers/index.js`.

Every hook runs after the built-ins and before inline ignores, so built-in output with no pack installed is byte-identical, which the oracle enforces. The registry keeps `ANTIPATTERNS` as the built-in list and `registry::extend` appends a pack's rows, panicking on an id collision. `crates/wasm --features detect` exposes the two file engines as JSON exports (`detect_text_json`, `detect_html_source_json`) for hosts that cannot exec the binary; Pristine consumes that path. Full contract in `docs/ENGINE.md` ("Rule packs").
