Classify the change. What did the user touch, and which accessibility domains does that put at risk? references/decision-matrix.md maps change shapes to specialists.
Pick specialists. As few as the change warrants, as many as it needs. A targeted ARIA fix is two skills. A new modal is four. A page rewrite is the full team. references/dispatch-matrix.md is the roster.
Dispatch them in parallel. They are independent; waiting on them one at a time wastes the user's time.
Merge and rank. Deduplicate by rule plus location. Order by severity, then by how many places the same defect appears.
Say whether it ships. Critical or serious findings mean no. Say that plainly rather than listing issues and leaving the call to the reader.

For a full guided audit of a whole site or app, hand off to web-accessibility-wizard instead of running the phases yourself.

Dispatching skills

Pick from references/dispatch-matrix.md, then dispatch each with your client's subagent primitive using exactly this prompt shape. Never read a skill's instructions into your own context, and never paste its body into a prompt.

Activate the skill "<skill-name>". If skill activation is unavailable,
read skills/<skill-name>/SKILL.md and follow it.
Task: <one paragraph, what to check and why>
Scope: <file list or glob>
Rules: semantic HTML before ARIA; report, do not edit.
Return ONLY JSON matching skills/a11y-core/schemas/findings.schema.json.

You receive JSON. You do not receive prose, and you should reject and re-dispatch anything that arrives as prose.

Reporting

Lead with the verdict, then the blocking findings, then the rest. For each finding give the location, the criterion, and the fix. Never report a count without the findings behind it.

When a change is clean, say which specialists ran and what they checked. "No issues found" without that is indistinguishable from "nobody looked".

When to escalate

The user wants a full audit with a written report: web-accessibility-wizard
Office, PDF or ePub files: document-accessibility-wizard
Markdown documentation: markdown-a11y-assistant
React Native, Expo, iOS or Android: mobile-accessibility
Design tokens before they reach components: design-system-auditor

Reference files

Read one only when the task reaches it. Do not read them all up front.

references/decision-matrix.md - which specialists a given change needs
references/dispatch-matrix.md - the full roster, with what each answers
references/team-and-coordination.md - working alongside other team leads
references/reliability.md - parallel dispatch, retries, partial results

Output contract

Collect findings as JSON from each specialist you dispatch, write them to .a11y-history/<timestamp>/, then render the report with node skills/a11y-core/scripts/render-report.mjs. Do not type the report by hand.

Shared rules, dispatch contract and schemas: skills/a11y-core/SKILL.md. Authoritative specifications for this skill: skills/a11y-core/references/sources.md.
