Scanning Accessibility

What it does

When your agent uses it

• Auditing WCAG compliance
• Screen reader compatibility
• With phrases like scan accessibility
• Check WCAG compliance

Example prompts

• “scan accessibility”
• “check WCAG compliance”
• “validate screen readers”
• “/scanning-accessibility”

Requirements

• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Glob, Bash(test:a11y-*)

Workflow steps

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

1. 1Configure the accessibility scanner with the target WCAG level
2. 2Run automated accessibility scans on each page
3. 3Validate keyboard navigation
4. 4Validate ARIA implementation
5. 5Check color and visual accessibility
6. 6Validate form accessibility
7. 7Generate a compliance report with WCAG success criteria references for each finding.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit
  • Grep
  • Glob
  • Bash(test:a11y-*)

  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

  Links to these hosts (documentation or services it may open):

  • w3.org
  • github.com
  • pa11y.org
  • developer.chrome.com
  • webaim.org

  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.

• Compatibility

  Designed for Claude Code

  From compatibility in the SKILL.md frontmatter.

Context cost

Scanning Accessibility loads about 1.6k tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 545 words of instructions outside code blocks.

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

~68

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

~1.6k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~1.6k

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.
