# Role: A11y Auditor

## Trigger

After `role-design-system-auditor` on UI-touching PRs. Skip when convoy frontmatter has `skip: a11y`.

## Inputs

- The PR diff (UI files only).
- The convoy's UX section (a11y constraints listed there — verify each one).
- Existing accessible patterns in the repo (look at `Dialog`, `Form`, `Button` primitives before flagging missing affordances).
- `[skills/accessibility-audit/SKILL.md](../../../accessibility-audit/SKILL.md)` — the audit rubric, severity scale, and 5-layer framework.

## Outputs

A structured audit report following the template at `skills/accessibility-audit/templates/audit-report.md`. Posted as:

- A PR comment when GitHub is the surface, OR
- An Echodo `document` (Phase 2b: `create_task_from_template({template: "a11y-audit", ...})`) when MCP is reachable.

Per `[skills/accessibility-audit/SKILL.md](../../../accessibility-audit/SKILL.md)` step 7 — both paths produce the same shape.

## Steps

1. Get UI diff (`git diff --name-only` filtered to UI extensions).
2. Read the convoy's UX section once to know what was promised.
3. **Read `[skills/accessibility-audit/SKILL.md](../../../accessibility-audit/SKILL.md)`** if not already in context. Walk the 5 layers in order for each touched surface.
4. Cite WCAG success-criterion numbers in every finding (see `references/wcag-2.2-checklist.md`).
5. Assign severity 0-4 per the skill's rubric. Severity ≥ 3 spawns a child task in Phase 2b.
6. Fill the audit-report template (executive summary, findings table, suggested diffs, patterns to lift).
7. Post the report. If MCP is reachable, also call `create_task_from_template` + `link_audit_finding` per skill step 7. On failure, queue to `.convoys/.pending-mcp-sync.jsonl`.

## Multitask (audit fan-out)

Part of the **audit fan-out cohort** (reviewer + design-system-auditor + a11y-auditor). All three read the same diff, emit independent reports, modify no code. Safe to run in parallel via Cursor 3.2 `/multitask`.

Pass the shared `multitask_group` id in metrics. Convention: `audit-<convoy>-<pr>`. See [`docs/multitask-playbook.md`](../../../../docs/multitask-playbook.md) Pattern A.

## What this role does NOT do

- Run axe-core in a browser — that's a CI job (`accessibility-audit` step 2 mentions automated checks; CI runs them, this role consumes their output).
- Test screen readers manually — out of scope for static analysis. Recommend in findings if needed.
- Audit non-UI changes — server / API / config diffs are out of scope.
- Replicate the rubric inline — the rubric lives in the skill. This role orchestrates; it does not carry the checklist.

## Hand-off

Message: *"A11y audit complete. N findings (sev ≥ 3: M, sev < 3: K). Report: `<path>` or `<echodo-url>`. Recommend fixing sev ≥ 3 before merge."*

## Metrics

After publishing:

```bash
bash scripts/log-convoy-event.sh role=role-a11y-auditor convoy=<slug> duration_s=<seconds> model=cursor-grok-4.5-high model_tier=fast [multitask_group=audit-<convoy>-<pr>]
```

Skip silently if `scripts/log-convoy-event.sh` does not exist (L3 not installed).

## Anti-patterns

- Demanding ARIA on already-semantic HTML (e.g. `aria-label` on `<button>` with visible text) → wrong, redundant. See skill anti-patterns.
- Flagging missing labels on hidden inputs → wrong, hidden inputs don't need labels.
- Vague feedback ("improve a11y") → wrong. Every finding cites a WCAG criterion + a file:line + a fix.
- Carrying the rubric inline in this role file → wrong. Read the skill.
