team-visual-a11y

# Team Visual Accessibility Deep visual accessibility QA: OKLCH-based perceptual color contrast, typography readability at all viewports, focus-visible completeness, WCAG AA/AAA audit at rendered level. Built on **team-worker agent architecture** -- all worker roles share a single agent definition with role-specific Phase 2-4 loaded from `roles/<role>/role.md`. ## Architecture ``` Skill(skill="team-visual-a11y", args="task description") | SKILL.md (this file) = Router | +--------------+--------------+ | | no --role flag --role <name> | | Coordinator Worker roles/coordinator/role.md roles/<name>/role.md | +-- analyze -> dispatch -> spawn workers -> STOP | +-------+-------+-------+ v v v | [3 auditors spawn in PARALLEL] | color-auditor typo-auditor focus-auditor | | | +---+---+---+---+ v remediation-planner | v fix-implementer (inner_loop) | v [re-audit: color + focus in PARALLEL] ``` ## Role Registry | Role | Path | Prefix | Inner Loop | |------|------|--------|------------| | coordinator | [roles/coordinator/role.md](roles/coordinator/role.md) | -- | -- | | color-auditor | [roles/color-auditor/role.md](roles/color-auditor/role.md) | COLOR-* | false | | typo-auditor | [roles/typo-auditor/role.md](roles/typo-auditor/role.md) | TYPO-* | false | | focus-auditor | [roles/focus-auditor/role.md](roles/focus-auditor/role.md) | FOCUS-* | false | | remediation-planner | [roles/remediation-planner/role.md](roles/remediation-planner/role.md) | REMED-* | false | | fix-implementer | [roles/fix-implementer/role.md](roles/fix-implementer/role.md) | FIX-* | true | ## Role Router Parse `$ARGUMENTS`: - Has `--role <name>` -> Read `roles/<name>/role.md`, execute Phase 2-4 - No `--role` -> `@roles/coordinator/role.md`, execute entry router ## Shared Constants - **Session prefix**: `VA` - **Session path**: `.workflow/.team/VA-<slug>-<date>/` - **team_name**: `visual-a11y` - **CLI tools**: `ccw cli --mode analysis` (read-only), `ccw cli --mode write` (modifications) - **Message bus**: `mcp__ccw-tools__team_msg(session_id=<session-id>, ...)` - **Max GC rounds**: 2 ## Worker Spawn Template Coordinator spawns workers using this template: ``` Agent({ subagent_type: "team-worker", description: "Spawn <role> worker for <task-id>", team_name: "visual-a11y", name: "<role>", run_in_background: true, prompt: `## Role Assignment role: <role> role_spec: <skill_root>/roles/<role>/role.md session: <session-folder> session_id: <session-id> team_name: visual-a11y requirement: <task-description> inner_loop: <true|false> ## Progress Milestones session_id: <session-id> Report progress via team_msg at natural phase boundaries (context loaded -> core work done -> verification). Report blockers immediately via team_msg type="blocker". Report completion via team_msg type="task_complete" after final SendMessage. Read role_spec file (@<skill_root>/roles/<role>/role.md) to load Phase 2-4 domain instructions. Execute built-in Phase 1 (task discovery) -> role Phase 2-4 -> built-in Phase 5 (report).` }) ``` ## User Commands | Command | Action | |---------|--------| | `check` / `status` | View execution status graph | | `resume` / `continue` | Advance to next step | ## Specs Reference - [specs/pipelines.md](specs/pipelines.md) -- Pipeline definitions and task registry - [specs/oklch-standards.md](specs/oklch-standards.md) -- OKLCH color accessibility rules - [specs/wcag-matrix.md](specs/wcag-matrix.md) -- WCAG 2.1 criteria matrix - [specs/typography-scale.md](specs/typography-scale.md) -- Typography accessibility rules - [specs/focus-patterns.md](specs/focus-patterns.md) -- Focus management patterns ## Session Directory ``` .workflow/.team/VA-<slug>-<date>/ +-- .msg/ | +-- messages.jsonl # Team message bus | +-- meta.json # Pipeline config + GC state +-- audits/ | +-- color/ # Color auditor output | | +-- color-audit-001.md | +-- typography/ # Typography auditor output | | +-- typo-audit-001.md | +-- focus/ # Focus auditor output | +-- focus-audit-001.md +-- remediation/ # Remediation planner output | +-- remediation-plan.md +-- fixes/ # Fix implementer output | +-- fix-summary-001.md +-- re-audit/ # Re-audit output (GC loop) | +-- color-audit-002.md | +-- focus-audit-002.md +-- evidence/ # Screenshots, traces ``` ## Error Handling | Scenario | Resolution | |----------|------------| | Unknown command | Error with available command list | | Role not found | Error with role registry | | Session corruption | Attempt recovery, fallback to manual | | Fast-advance conflict | Coordinator reconciles on next callback | | Completion action fails | Default to Keep Active | | GC loop stuck > 2 rounds | Escalate to user: accept / retry / terminate | | Chrome DevTools unavailable | Degrade to static analysis only | --- > Source: [catlog22/Claude-Code-Workflow](https://github.com/catlog22/Claude-Code-Workflow) — distributed by [TomeVault](https://tomevault.io). <!-- tomevault:4.0:skill_md:2026-06-19 -->
