Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.01350 |
| Opus 5 | $0.00024 | $0.00675 |
| Sonnet 5 | $0.00010 | $0.00270 |
| Haiku 4.5 | $0.00005 | $0.00135 |
Grade A, and why
auditing-wcag 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 13d 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.
How it starts
The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
WCAG Conformance Audit
You perform WCAG 2.2 AA conformance audits. Report Pass/Fail/NT/NA per success criterion with evidence.
When to Use This Skill
| Perspective | reviewing-a11y | auditing-wcag |
|---|---|---|
| Goal | Find issues and propose fixes | Systematic conformance verification |
| Output | Severity-based issues list | Pass/Fail/NT/NA per success criterion |
| Scope | Practical issues focus | Full WCAG 2.2 A/AA coverage |
Routing Rules
- auditing-wcag: Requests for "audit", "compliance", "conformance", or formal reporting.
- reviewing-a11y: Requests for "review", "find issues", "improvements", or dev feedback.
- If unclear, ask which goal they want: compliance report or issue review.
Workflow (6 Steps)
1. Input Acceptance
- Accept a URL or local file path.
- For multiple pages, confirm the list and entry points.
- For local files, use the available file-reading capability (runtime behavior cannot be executed).
2. Scope Contract
Confirm and get agreement on:
- Target level (A/AA, default WCAG 2.2 AA)
- Page scope (all pages / representative pages / provided URLs)
- Limitations (AT checks out of scope, dynamic behavior depends on Playwright)
- Output format (Pass/Fail/NT/NA per success criterion)
3. Automated Checks
- Use Playwright to navigate and capture the accessibility tree.
- Apply
references/automated-checks.md. - If browser interaction is unavailable, run the checks via the
a11y-auditCLI (see "Automated Checks CLI" below). - If the CLI also cannot run, retrieve HTML with the available web capability and limit judgments accordingly.
- Use
references/coverage-matrix.mdto ensure A/AA coverage.
4. Interactive Checks
- Validate keyboard access and focus behavior with Playwright.
- Follow
references/interactive-checks.md. - If execution is blocked, mark affected criteria as NT.
5. Manual Check Items
- Present items from
references/manual-checks.mdandreferences/content-checks.md. - If evidence is not available, keep them as NT and list them explicitly.
- Incorporate any evidence the user provides.

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.

auditing-wcag is a skill published in the GitHub repository masuP9/a11y-specialist-skills (56 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 1,350 once invoked, about $0.0002 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 2026-08-30.
