Accessibility — Skill Entry

This skill is the canonical accessibility reference contract for HVE Core. Agents and instructions invoke this skill by name and rely on it to own framework reference resolution, phase guidance resolution, and the scanner CLI entrypoint.

Framework references

• WCAG 2.2
• ARIA Authoring Practices Guide
• Cognitive Accessibility Guidance
• Section 508
• EN 301 549
• Graphics ARIA and SVG-AAM

Assessment reference (cross-cutting, not a conformance framework):

• Assistive-technology announcement model — read this when deciding the announcement-class criteria (WCAG 1.3.1, 4.1.2, 4.1.3): what a screen-reader user should hear, and how to decide it with an accessibility-tree assertion or a manual AT pass.

Accessibility Planner workflow

The Accessibility Planner runs six phases, each keyed to a state id:

1. Phase 1 — Discovery (discovery)
2. Phase 2 — Framework Selection (framework-selection)
3. Phase 3 — Standards Mapping (standards-mapping)
4. Phase 4 — Plan Risk Assessment (plan-risk-assessment)
5. Phase 5 — Impact and Evidence (impact-evidence)
6. Phase 6 — Backlog Handoff (backlog-handoff)

Phase reference index

• Phase 1 — Discovery: capture-coaching.md — read this when running exploration-first capture questioning.
• Phase 2 — Framework Selection: framework-selection.md — read this when choosing which frameworks and conformance level apply.
• Phase 3 — Standards Mapping: walk the framework references roll-up tables to emit controlMappings; consumed by Phase 5. No dedicated file — mapping is driven by the framework roll-ups.
• Phase 4 — Plan Risk Assessment: capture-coaching.md governs the questioning posture when escalation triggers reopen scoping; tier criteria are applied per the Accessibility Planner identity instructions and recorded as riskClassification.tier. No dedicated file — the accessibility risk surface is narrow enough to stay inline.
• Phase 5 — Impact and Evidence: impact-assessment.md — read this when building the evidence register, tradeoff log, and seed work-items.
• Phase 6 — Backlog Handoff: backlog-handoff.md — read this when rendering work items and validating handoff gates.
