audit-a11y

audit-a11y is a skill for Claude Code from VoxTechnologies/transmute-framework. It costs 86 tokens per session (3,346 once invoked), scanned A, original, MIT.

A review of a website or application’s frontend against WCAG, the international guidelines for making software usable by people with disabilities. It checks issues such as screen-reader support and keyboard navigation.

In plain words
What is it for?
Use it to audit and fix accessibility issues in frontend code, including WCAG violations, screen-reader support, and keyboard access.
Why use it?
It identifies accessibility problems that can prevent people from reading, navigating, or using the interface.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

audit-a11y scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Accessibility Audit — Stage 6B

Read the detailed guide at ${CLAUDE_SKILL_ROOT}/references/audit-a11y-detailed-guide.md for the complete audit procedures, teammate spawn prompts, WCAG checklist patterns, and report templates.

Lead a multi-agent accessibility audit of the complete frontend codebase against BRD/PRD WCAG requirements. Identify violations and fix them.

Stage Sequence (recommended ordering): Stage 5B → (6A ‖ 6B (this stage) ‖ 6C) → 6E → 6F → 6G → 6D → 6H → 6V → 6R → 6P/6P-R → 7 (Deploy). Note: 6A, 6B, and 6C run in parallel (each in a separate session). If running in parallel, commit 6A changes as soon as 6A completes to avoid config file conflicts — see CLAUDE.md § "Stage 6 ordering".

Prerequisite Checks

Before any audit work, verify:

  1. Check that ./plancasting/_audits/implementation-completeness/report.md exists and shows PASS or CONDITIONAL PASS. If missing, STOP: "Stage 5B report not found — run Stage 5B before starting Stage 6 audits." (Override: if the operator explicitly confirms 5B was intentionally skipped, proceed with a WARN in the report noting unverified implementation completeness.)
  2. If 5B shows FAIL, STOP — the codebase has unresolved implementation gaps that must be fixed before accessibility auditing. If CONDITIONAL PASS, read documented Category C issues and skip accessibility auditing for those incomplete features.
  3. If ./plancasting/_audits/security/report.md (6A) exists, read it to understand security changes that should not be undone during accessibility fixes (e.g., CSP headers, CORS configuration).
  4. If ./plancasting/_audits/performance/report.md (6C) exists, read it to understand performance optimizations (e.g., font loading, animation patterns, lazy loading) that should not be regressed.
  5. Read ./CLAUDE.md and ./plancasting/tech-stack.md for project conventions.
  6. Read relevant PRD sections for implementation context.

Inputs

  • Codebase: ./src/ (adapt paths per tech stack)
  • Tech Stack: ./plancasting/tech-stack.md
  • BRD Accessibility Requirements: ./plancasting/brd/08-non-functional-requirements.md (WCAG section). If not found, search: grep -rlE "WCAG|accessibility" ./plancasting/brd/
  • BRD UX Requirements: ./plancasting/brd/11-user-experience-requirements.md
  • PRD Screen Specs: ./plancasting/prd/08-screen-specifications.md (accessibility annotations)
  • PRD Interaction Patterns: ./plancasting/prd/09-interaction-patterns.md
  • Project Rules: ./CLAUDE.md
  • Implementation Completeness: ./plancasting/_audits/implementation-completeness/report.md

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

audit-a11y is a skill published in the GitHub repository VoxTechnologies/transmute-framework (4 stars, last pushed 1mo ago), licensed MIT. It adds 86 tokens to every session and 3,346 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
