Runs WCAG 2.2 AA accessibility audits on generated UI — axe-core/pa11y for web, a terminal a11y checklist for tui. Posts findings as PR comments. Blocks merge on critical/serious violations. Required for all ui:true stories.
Produces staff-level system design documentation including ADRs, API contracts, threat models, and Mermaid architecture diagrams. Enforces BusinessRepo, Clean Architecture, and SOLID.
Authors the design token system. Reads palette.json and typography.json, writes canonical tokens.json (W3C DTCG), and emits the identity outputs for the active design.target — CSS vars + Tailwind + Mantine for web, terminal-theme.json for tui. Maintains component inventory. Uses the design-tokens skill.
Primary orchestrator agent. Controls the entire 8-phase pipeline. Never writes code — delegates all implementation to specialist agents. Manages GitHub issues, quality gates, and escalation.
BDD automation agent. Extracts Gherkin from docs/stories/ into tests/features/, generates step definition stubs, runs the BDD suite, and reports results. Works alongside the QA agent — QA writes tests, qa-cucumber connects them to runnable BDD scenarios.
Independent second-opinion reviewer. Invoked by the orchestrator after planning, after complex implementations, and after writing tests. Surfaces a short, high-signal list of concerns — bugs, design flaws, edge cases, missing error handling — without commenting on style or formatting.
