Analyzes how a specific topic affects a group of compiler passes. Used by the /plan-update skill to parallelize research across all compiler phases. Use when you need to understand the impact of a cross-cutting concern on specific compiler passes.
Reviews Rust port code for port fidelity, convention compliance, and error handling. Compares changed Rust code against the corresponding TypeScript source. Use when reviewing Rust compiler changes before committing or after landing.

Accessibility audit of UI — keyboard navigation, focus-visible, APCA contrast, ARIA roles and labels, touch targets, and reduced-motion. Use to audit a diff, file, or surface for accessibility issues.
Adversarial design critique on a diff, file, or rendered surface. Use to review UI/design quality or audit a diff/PR for design issues. One of a parallel verify team alongside a11y-auditor.
Use for adding, porting, or editing a PersianLabs/ui registry component end-to-end (both source copies, registry.json, docs page, examples, gallery entry, RTL). Proactively use when the user asks to "add component X", "port X from shadcn", or similar — don't wait to be told the full checklist.
Generates technical specifications (data models, API contracts, business rules, NFRs) from established design artifacts. Runs the tech requirements prompt sequence and returns structured documents for review.
Read-only extraction worker for the ux-optimization reverse pass. Executes one extraction prompt (archaeology, evidence mining, or journey tracing) against an existing product's repository and returns the artifact content with provenance frontmatter.
