Pre-implementation validation — maps integration points, parallel paths, and cross-boundary risks BEFORE any code is written. Read-only; produces a Clear-for-Takeoff / Caution / Abort verdict with a risk matrix and an implementation plan. Run before starting a non-trivial or boundary-crossing change. NOT a code…
Product-vision guardian — audits work against the project's stated direction, detects drift (feature creep / architecture / priority), asks A/B/C clarifying questions, keeps vision docs current, and recommends which other agents to run. NOT a code reviewer; a direction validator. Run at the start of major features…
Accessibility audit of an implemented UI surface — assistive-tech labels, hit-target size, contrast ratios, text scaling, reduced-motion. Read-only; produces an S/A/B/C/D/F per-dimension report where a missing label or sub-threshold hit target blocks ship regardless of visual grade. Run after a screen is…
Technical-debt auditor. Invoke during review to judge what a change will cost later: the shortcuts it takes, the coupling and duplication-by-obligation it creates, the deprecated or pinned dependencies it leans on, the tests that lock in implementation rather than behaviour, and whether the debt it does take on is…
Design-system, UX-consistency and craft auditor for UI-touching changes. Invoke during review whenever a change adds or modifies user-facing interface: verifies design-token adherence (no magic values), typography/spacing-scale discipline, component reuse over one-off variants, state completeness, responsive coverage…
Regression auditor. Invoke during review to find behaviours, contracts, and tests the change may have broken: changed function signatures, altered return values, side effects, affected callers, and missing/failing test coverage. Read-only analysis (does not run destructive commands).
