| description | Use to REVIEW code changes for accessibility — '/review-a11y', 'review my changes/PR/branch for a11y', 'accessibility review of this diff'. Scopes to exactly the code under change (staged files, working diff, or branch vs merge-base), runs the bundled install-free ultra11y engine (node scripts/ultra11y.mjs, no keys; static WCAG 2.2 AA checks tied to success criteria, cross-file JSX/TSX via --graph), then adds YOUR judgment: refute false positives (SFC/library-source findings are preliminary), decide alt relevance and link purpose, name the rendering criteria (contrast, focus, zoom) as residual risks — never invent a non-conformity. Output: a severity-ranked review (blocking → major → minor) with file:line, concrete fixes, residual risks and a one-line verdict, in the conversation's language (technical tokens stay in English). Companion of the ultra11y skill (full audits, reports, PRD, RGAA packs). Triggers: 'review a11y', 'a11y review', 'accessibility review'. |

review-a11y — accessibility review of changed code
The review counterpart of the ultra11y skill: where ultra11y produces full audits and
compliance deliverables, this skill reviews exactly the code under change — a diff, a
branch, a PR — and reports like a code reviewer. Same division of labour: the
deterministic, install-free engine bundled with this skill does the mechanical work
(machine-checkable WCAG 2.2 AA non-conformities, each tied to a success criterion, cited
file:line), and the AI agent adjudicates the judgment — refute false positives, decide
alt relevance/link purpose/focus logic statically from the code, and route what needs a rendered
DOM to scan. A human is at most optional oversight.
Engine resolution: every command below is node scripts/ultra11y.mjs … where
scripts/ultra11y.mjs lives next to this SKILL.md (the engine ships inside the skill;
no install, no key). Run it with the reviewed project as the working directory. In the
ultra11y repository itself, the repo root's scripts/ultra11y.mjs is the same file.
Core rules (shared with ultra11y):
- Never invent a non-conformity: report only what the engine found or what you can
see and cite in the code under review.
- Review the change, not the world: findings outside the reviewed scope are noted in
one line at most ("pre-existing, out of scope"), never mixed into the verdict.
- Residual is explicit, never silently conforming: the rendering criteria (contrast,
focus visibility, zoom/reflow, content-on-hover) are named as residual risks for the changed
components — never asserted from source, resolved in the rendered page (
scan). The
judgment criteria (alt relevance, link purpose, reading order) the AI agent adjudicates
from the code itself, recording a reason — no status without a justified verdict.
- Language: write the review in the conversation's language, but technical tokens
stay in English even in French prose —
aria-live stays aria-live (never
« région live »), same for tabindex, alt, role="alert", landmark role names.
1. Scope — review what changed
Pick the FIRST that applies (ask only when genuinely ambiguous):
node scripts/ultra11y.mjs audit <files the user named> --jsx --json # explicit files
node scripts/ultra11y.mjs audit --staged --graph --json # staged snapshot (pre-commit review)
node scripts/ultra11y.mjs audit --changed --graph --json # working diff
node scripts/ultra11y.mjs audit --since origin/main --graph --json # the whole branch (PR review) — use the repo's default branch
- Always pass
--graph for JSX/TSX (real AST + cross-file rules: icon-only component used
without a name, anchor target defined in another file…); it also suppresses a class of
single-file false positives.
- Pass
--lang matching the conversation so the engine's message/remediation strings are
in the review's language (unset, the CLI auto-detects — a fallback, not a substitute).
- Whole-repo review is an audit, not a review — offer the
ultra11y skill instead.
- Test/story markup (
*.test.*, *.stories.*, __tests__/) is excluded by default; name
such a file explicitly to include it, or pass --no-default-excludes.
2. Judge — the engine's findings are candidates, not verdicts
For each finding (--json gives criteria, severity, file:line, message,
remediation):
- Confirm the occurrence: open the cited line; the offending element must really be
there in the change under review.
preliminary: true findings (.vue/.svelte/.astro source, library components):
the template parser cannot see slots, conditionals or provide/inject wiring. Confirm
against the rendered DOM if captures exist (.ultra11y/captures, from the ultra11y
skill's render --setup harvester), otherwise report them as provisional with that
caveat — or refute them with evidence from the code.
- Library-rendered JSX (DSFR, MUI…): a clean source review can still ship broken HTML
(false negatives) — say so explicitly when the change touches such components, and
recommend a rendered-DOM check (
scan, or the ultra11y capture pipeline).
- The judgment criteria are the AI agent's to adjudicate: alt text relevance, link purpose
in context, visible label vs accessible name, keyboard/focus logic of the changed component
(read the full component source, not just the flagged line), recording a reason for each call.
- Refuting a finding requires cited evidence (the code that disproves it); silently
dropping findings is forbidden.
3. Report — a review, not a compliance document
Render in the conversation's language (Core rule 4), grouped by severity:
## Accessibility review — <scope, e.g. branch feat/x vs main, 12 files>
### 🔴 Blocking
- `src/components/Form.tsx:42` — **3.3.2 Labels or Instructions** — input has no
label and placeholder is its only hint → associate a real <label for>, keep the
placeholder as an example only.
### 🟠 Major / 🟡 Minor
- …same shape…
### Residual risks (rendering-dependent — resolve in the rendered page via scan)
- contrast of the new button variants (1.4.3), focus visibility on the custom menu (2.4.7)
### Verdict
1 blocking, 2 major to fix before merge; 2 provisional SFC findings to confirm on the
rendered DOM; residual risks listed above.
- Keep the engine's
remediation text as the base of each fix — it is already localized
and criterion-grounded.
- Pre-existing issues spotted in passing go in ONE final line, out of the verdict.
4. After the review (opt-in)
- Safe mechanical fixes:
fix --staged --write --safe (auto-applies the safe codemods
to staged files and re-stages them) or node scripts/ultra11y.mjs fix <files> --write;
dry-run without --write.
- Formal deliverables (dated report, auditor conformance blocks, PRD backlog, GitHub
issues, RGAA/country-standard vocabulary): that is the
ultra11y skill — same engine,
same findings (report, prd, check/verify gates).
- Make it automatic: the
ultra11y skill's init --hook installs a pre-commit gate
running this same staged review mechanically.
Do not
- Invent a non-conformity the engine did not find and you cannot cite.
- Assert contrast/focus/zoom from source — they are residual risks until rendered (resolve via
scan).
- Mix pre-existing repo issues into the verdict on the change.
- Translate technical tokens in French prose (
aria-live, never « région live »).
