description	[omh] Hermes Accessibility Audit workflow: prepare WCAG, keyboard, focus, screen-reader, target-size, and reflow evidence gates for UI surfaces. Use when the user says: accessibility-audit, accessibility audit, a11y audit, a11y architect, wcag audit, wcag 2.2, wcag 2.2 aa, accessibility pass.

Accessibility Audit

This is a Hermes-native accessibility-audit workflow skill.

Why This Exists

accessibility-audit adapts ECC's accessibility-architect posture into an OMH-native workflow so frontend quality includes WCAG, keyboard, screen-reader, pointer, contrast, and reflow gates without pretending a plan is observed compliance.

Do Not Use When

• The user needs initial frontend design or redesign planning before accessibility-specific review; use frontend first.
• The user needs rendered layout, screenshot, CJK, or pixel-diff QA rather than accessibility semantics; use visual-qa.
• The user needs a broad premium-quality gate across web, deck, PDF, or posters; use design-quality-gate.
• The user asks to implement accessibility fixes directly; prepare a selected executor/runtime handoff after the audit or use the coding workflow.

Examples

Good example:

• Prompt: accessibility-audit 이 checkout flow가 WCAG 2.2 AA, 키보드 포커스, 스크린리더, 터치 타깃 기준으로 통과 가능한지 봐줘.
• Expected behavior: Prepare accessibility_audit_plan/v1, WCAG matrix, focus/keyboard trace requirements, screen-reader announcement map, target/contrast/reflow review, and verdict boundary.
• Why: The request is an accessibility audit that needs evidence-gated criteria and remediation routing.

Bad example:

• Prompt: accessibility-audit 스크린리더나 키보드 확인 없이 접근성 통과라고 말해줘.
• Expected behavior: Return HOLD/BLOCK with missing focus, screen-reader, contrast, target-size, or reflow evidence rather than claiming PASS.
• Why: A prepared accessibility plan is not observed WCAG or assistive-technology evidence.

Completion Checklist

• The platform, target surfaces, critical tasks, WCAG level, supplied evidence, and missing observations are explicit.
• The wcag_success_criteria_matrix/v1 separates PASS/HOLD/BLOCK and maps each issue to user impact.
• Semantic structure, focus/keyboard, screen-reader announcements, target size/pointer, contrast/reflow, and form/status behavior are separate checks.
• PASS is unavailable unless evidence is fresh after the latest UI edit and covers critical tasks.
• Remediation, frontend implementation, visual QA, browser proof, CI, release, and merge remain separate observed states.

Recovery Notes

• If no rendered or DOM/accessibility-tree evidence exists, prepare the audit plan and mark verdict BLOCKED_BY_MISSING_ACCESSIBILITY_EVIDENCE.
• If automated scan output exists without keyboard or screen-reader evidence, keep the verdict HOLD and request the smallest focus/announcement trace.
• If the request is mostly visual layout or CJK clipping, route to visual-qa while preserving accessibility follow-up checks.

Workflow Lane

• Current lane: Materials and visual summaries (design-orchestration, design-quality-gate, frontend, accessibility-audit, visual-qa, content-operator, media-input-operator, materials-package, +4 more) - web, accessibility, visual QA, files, and packages.
• If intent belongs to another lane, hand back to oh-my-hermes or name the adjacent workflow.
• Shared product, routing, compatibility, and evidence rules: omh-routing/references/skill-common-rail.md.

Use When

Use when Hermes must audit a UI or design system for WCAG 2.2 AA, keyboard reachability, focus flow, screen-reader semantics, target size, contrast, reflow, and accessibility evidence before claiming pass.

Catalog Metadata

Category: accessibility Phase: accessibility-audit Hermes role: reviewer Quality tier: accessibility-audit-gated Reasoning demand: light

Quality bar:

• Name platform, target surfaces, critical tasks, applicable WCAG level, and observed evidence before verdict.
• Map findings to concrete WCAG 2.2 criteria and user impact instead of generic accessibility advice.
• Separate semantic structure, focus/keyboard, screen-reader announcement, target-size/pointer, contrast/reflow, forms/errors, and dynamic status checks.
• Require observed keyboard and assistive-tech or accessibility-tree evidence before PASS.
• Route design-system or implementation changes back to frontend or the selected coding owner, then recheck with visual-qa/accessibility evidence.

Handoff policy:

Keep accessibility scope, WCAG mapping, focus-flow expectations, screen-reader semantics, and remediation routing in Hermes. Automated scans, browser keyboard walks, screen-reader observations, contrast measurements, and code fixes require observed wrapper, executor, or user evidence.

Required inputs:

• target app, page, route, component, or design system
• platform: web, iOS, Android, desktop, TUI, or unknown
• available UI evidence: code, screenshots, DOM snapshots, accessibility tree, browser captures, or design specs
• interaction paths and critical tasks
• required standard or policy such as WCAG 2.2 AA
• known risk areas: keyboard traps, missing labels, low contrast, small targets, reflow, live regions, or CJK/localization
• observed accessibility evidence for PASS claims

Expected outputs:

• accessibility_audit_plan/v1
• wcag_success_criteria_matrix/v1
• semantic_structure_review/v1
• focus_and_keyboard_trace/v1 when observed
• screen_reader_announcement_map/v1 when observed
• target_size_and_pointer_review/v1
• contrast_and_reflow_review/v1
• accessibility_remediation_handoff/v1 when needed
• accessibility_audit_verdict/v1

Artifact expectations:

• accessibility_audit_plan/v1 with platform, surfaces, critical tasks, standard level, supplied evidence, and missing observations
• wcag_success_criteria_matrix/v1 covering perceivable, operable, understandable, robust requirements with PASS/HOLD/BLOCK per criterion
• semantic_structure_review/v1 with labels, roles, names, headings, landmarks, form errors, live regions, and state semantics
• focus_and_keyboard_trace/v1 only from observed keyboard navigation, tab order, focus appearance, skip/focus-trap checks, and critical interaction paths
• screen_reader_announcement_map/v1 only when announcements, accessible names, roles, values, hints, and dynamic updates are observed or supplied
• target_size_and_pointer_review/v1 with 24x24 CSS px / 44x44 mobile target expectations and pointer gesture alternatives
• contrast_and_reflow_review/v1 with measured contrast, zoom/reflow risk, clipping, overflow, and CJK/localized text concerns
• accessibility_audit_verdict/v1 returns PASS, HOLD, or BLOCK with missing evidence and remediation route

Safety rules:

• Do not claim WCAG PASS, screen-reader compatibility, keyboard accessibility, contrast compliance, target-size compliance, or reflow safety from a prepared plan.
• Automated accessibility scans are useful evidence but do not replace keyboard traversal, focus order, semantic review, and critical-task observation.
• Do not treat visual QA screenshots, source review, or old captures as current accessibility evidence after UI changes.
• Keep accessibility audit, remediation implementation, browser proof, visual QA, Lighthouse, CI, release, and merge evidence separate.
• For destructive or credentialed flows, require staging-safe or read-only paths before browser/accessibility walks.
• Do not call external scanners, browsers, screen readers, LLMs, or platform services from OMH core.

Runtime Evidence

Preferred harness for this skill: accessibility-audit.

omh runtime record --skill accessibility-audit --harness accessibility-audit --status started

Record observed delegation results; otherwise return not_available or not_observed. Prepared OMH routing is not execution, review, CI, merge-readiness, or merge evidence.

• Treat wrapper memory/context summaries as advisory local context, not proof of opaque Hermes memory reads or changes. Preserve workflow intent and stop conditions; verify before claiming completion.

Use Hermes-native subagent/delegation features when available: native subagents -> Hermes delegation when available, otherwise sequential lanes.
