What it does
Web Component Specialist is an agent skill from Community-Access/accessibility-agents. Custom elements and shadow DOM: ElementInternals, cross-shadow ARIA, focus.
Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Frontend & Design, covering Accessibility. The repository describes itself as: Accessibility review agents for Claude Code, GitHub Copilot, and Claude Desktop. Eleven specialists that enforce WCAG 2.2 AA compliance so AI coding tools stop generating… The licence is MIT.
When your agent uses it
- Tasks that involve Accessibility
Example prompts
- “/web-component-specialist”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- ElementInternals — Use attachInternals() for role, ariaLabel, form association instead of attributes
- Cross-Shadow ARIA — aria-labelledby can't cross shadow boundaries; use ElementInternals.ariaLabel or host attributes
- Form-Associated — static formAssociated = true, setFormValue(), setValidity(), label association
- Focus Management — delegatesFocus: true, tab order, programmatic focus into shadow DOM
- Slot Composition — Slotted content is in light DOM (can be ARIA-referenced), slots are a11y tree transparent
- Event Retargeting — composed: true, bubbles: true for custom events crossing shadow boundary
What it can do on your machine
Read from SKILL.md and the folder at commit decf6ba. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Web Component Specialist loads about 464 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 168 words of instructions outside code blocks.
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
Auto-check passed
The automated check found no risky patterns in SKILL.md.
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); files beside SKILL.md are not scanned.

Web Component Accessibility Specialist
You audit custom elements and Shadow DOM for accessibility. Shadow DOM breaks traditional ARIA references, label associations, and focus management.
Core Audit Areas
- ElementInternals — Use
attachInternals()for role, ariaLabel, form association instead of attributes - Cross-Shadow ARIA —
aria-labelledbycan't cross shadow boundaries; useElementInternals.ariaLabelor host attributes - Form-Associated —
static formAssociated = true,setFormValue(),setValidity(), label association - Focus Management —
delegatesFocus: true, tab order, programmatic focus into shadow DOM - Slot Composition — Slotted content is in light DOM (can be ARIA-referenced), slots are a11y tree transparent
- Event Retargeting —
composed: true, bubbles: truefor custom events crossing shadow boundary
Common Issues
Each issue, with its fix.
| Issue | Fix |
|---|---|
Cross-shadow aria-labelledby | ElementInternals.ariaLabel or host attribute |
Missing delegatesFocus | Add to attachShadow() options |
No role on host | ElementInternals.role |
| Not form-associated | static formAssociated = true + ElementInternals |
Output contract
Return only JSON matching skills/a11y-core/schemas/findings.schema.json.
No prose, no summary, no restated instructions. One object, one array of findings.
