gsp-accessibility

name	gsp-accessibility
description	Audit accessibility — contrast, tokens, screens, code, or compliance statement. Picks the right mode from project state when invoked with no flags — use when: is this accessible, check contrast, WCAG check, a11y audit, accessibility report, before we ship, accessibility statement

Unified accessibility skill — every WCAG mode lives here. Merges the former `gsp-accessibility` (quick checks, token audit, pre-emit validate gate) and `gsp-accessibility-audit` (design audit, code audit, compliance statement) into one context-aware router.

Two consumption patterns:

1. Standalone — user runs /gsp-accessibility and the skill picks the right mode from project state, or runs an explicit --mode
2. As a building block — gsp-brand-guidelines calls --validate as a pre-emit gate; gsp-project-critique and gsp-project-review reuse the chunks this skill writes

Accessibility runs at multiple checkpoints in the pipeline (brand emit, post-design, post-build, pre-ship). The mode determines which checkpoint.

Run the right accessibility check for the project's current state.

Input: Mode flag (or none — auto-pick) + optional arguments Output: Display, chunk file, statement, or audit log depending on mode Agent: gsp-accessibility-auditor (only in --design and --code modes)

- Always use `AskUserQuestion` for user interaction — never prompt via plain text - One decision per question — never batch multiple questions in a single message - Quick check mode (`--check`) and validate mode (`--validate`) never write chunk files - `--validate` carries verdict via exit code; do not swallow exit 1 - Default conformance level is AA unless overridden by `--level AAA` or project config - Foundation chunks follow `chunk-format.md` format ## Step 1: Parse invocation

Read $ARGUMENTS to determine the mode:

Input	Mode	Sibling	Agent?	Output
--check #FG #BG	Quick contrast	modes/check.md	No	Display only
--validate <yml>	Pre-emit WCAG gate	modes/validate.md	No	Stdout verdict + <yml-dir>/wcag-validate.log
--tokens	Brand token audit	modes/tokens.md	No	critique/accessibility-token-audit.md
--design	Design screen audit	modes/design.md	Yes	critique/accessibility-audit.md + fixes
--code	Codebase audit	modes/code.md	Yes	review/accessibility-audit.md + fixes
--statement	Compliance statement	modes/statement.md	No	exports/accessibility-statement.md
(no args)	Context-aware default	—	depends	depends

Additional flag: --level AAA overrides conformance level (default: AA).

Step 2: Context-aware default (no args)

When invoked with no mode flag, pick the right mode from project state:

1. No .design/projects/ and no yml path → mode picker via AskUserQuestion:
   • "Quick contrast check (--check)"
   • "Audit a brand token file (--tokens)"
   • "Validate a brand yml (--validate)"
   • "Run a full audit on this project (resolves below)"
2. Brand mid-emit (gsp-brand-guidelines is the caller) → --validate {yml} (callers pass it explicitly; this clause is a safety net)
3. Project exists with design phase complete and no critique/accessibility-audit.md → --design
4. Project exists with build phase complete and no review/accessibility-audit.md → --code
5. Project exists with both audits present → offer --statement
6. Project exists with neither phase complete → tell user to complete a phase first; offer --tokens if a brand exists

Once the mode is resolved (explicit or auto-picked), continue to Step 3.

Step 3: Route to mode

Load the matching sibling and follow its instructions:

• ${CLAUDE_SKILL_DIR}/modes/check.md
• ${CLAUDE_SKILL_DIR}/modes/validate.md
• ${CLAUDE_SKILL_DIR}/modes/tokens.md
• ${CLAUDE_SKILL_DIR}/modes/design.md
• ${CLAUDE_SKILL_DIR}/modes/code.md
• ${CLAUDE_SKILL_DIR}/modes/statement.md

Each mode file is self-contained: it resolves its own context (project, brand, conformance level), describes its checks, and specifies its output. Agent-spawning modes (--design, --code) also reference ${CLAUDE_SKILL_DIR}/wcag-checklist.md and ${CLAUDE_SKILL_DIR}/methodology/gsp-accessibility-auditor.md.

Step 4: Update STATE.md (chunk-writing modes only)

After --tokens, --design, or --code finish, if running within a project and chunk files were written:

• Read {PROJECT_PATH}/STATE.md
• Note accessibility audit completion in the relevant phase section
• Do not change phase status — accessibility is a supplementary check across phases, not a phase itself

--check, --validate, and --statement do not update STATE.md (no chunk written, or output is final artifact not phase progress).
