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.

Role Registry

Role	Path	Prefix	Inner Loop
coordinator	roles/coordinator/role.md	--	--
color-auditor	roles/color-auditor/role.md	COLOR-*	false
typo-auditor	roles/typo-auditor/role.md	TYPO-*	false
focus-auditor	roles/focus-auditor/role.md	FOCUS-*	false
remediation-planner	roles/remediation-planner/role.md	REMED-*	false
fix-implementer	roles/fix-implementer/role.md	FIX-*	true

Pre-load (coordinator, before dispatch)

1. Codebase docs: If .workflow/codebase/ARCHITECTURE.md exists, read for module boundaries
2. Specs (ui): maestro load --type spec --category ui — load ui constraints as shared context
3. Wiki knowledge: maestro search "accessibility WCAG contrast" --json — top 5 entries as prior context
4. All optional — proceed without if unavailable

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: {run_dir}/work/team/
• team_name: visual-a11y
• CLI tools: maestro delegate --mode analysis (read-only), maestro delegate --mode write (modifications)
• Message bus: mcp__maestro__team_msg(session_id=<run-id>, ...)
• Max GC rounds: 2

Worker Spawn Template

Coordinator spawns workers using this template:

teammate({ agent: "team-worker", name: "<role>", description: "Spawn <role> worker for <task-id>", context: "fresh" })

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
