Accessibility Testing

What it does

When your agent uses it

• Ensuring legal compliance (ADA
• Testing for disabilities
• Building accessible applications for 1 billion disabled users globally

Example prompts

• “/accessibility-testing”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1APPLY POUR principles: Perceivable, Operable, Understandable, Robust
2. 2TEST with keyboard-only navigation (Tab, Enter, Escape)
3. 3VALIDATE with screen readers (VoiceOver, NVDA, JAWS)
4. 4CHECK color contrast (4.5:1 for text, 3:1 for large text)
5. 5AUTOMATE with axe-core, integrate in CI/CD pipeline

What it can do on your machine

Read from SKILL.md and the folder at commit 829d030. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 1 file in scripts/, which the agent can run.

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Accessibility Testing loads about 2k tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 469 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~67

When it runs · the whole SKILL.md, loaded when a task matches

~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
