Implement WCAG 2.1 AA / 2.2 accessibility: semantic HTML audit, ARIA implementation, keyboard navigation, screen reader testing, color contrast. Use when user asks to "implement accessibility", "fix a11y issues", "make WCAG compliant", or "audit for accessibility".

Report a bug against an existing feature — creates a structured bugs.md record, generates fix tasks in tasks.md, and optionally imports from or creates GitHub issues. Use when fixing a bug, reporting a defect, importing a GitHub issue into the workflow, or triaging an error without running the full specification process.

Validate cross-artifact consistency — checks that every spec requirement traces to tasks, plan tech stack matches task file paths, and constitution principles are satisfied across all artifacts. Use when running a consistency check, verifying requirements traceability, detecting conflicts between design docs, or auditing alignment before implementation begins.

Generate Gherkin .feature files from requirements before implementation — produces executable BDD scenarios with traceability tags, computes assertion integrity hashes, and locks acceptance criteria for test-driven development. Use when writing tests first, doing TDD, creating test cases from a spec, locking acceptance criteria, or setting up red-green-refactor with hash-verified assertions.

THE CRITICAL SKILL -- validates hooks.json structure, event names, and type-event compatibility. Detects prompt/agent hooks on events lacking ToolUseContext. Triggers: validate hooks, check hooks.json, hooks audit, hook safety check.
