alignmentGeneralist reviewer. Checks the execution plan against the approved product brief, the project's architecture document, and product/UX goals. Owns the first-pass tier — flags which specialist dimensions need deeper review.
boundariesSpecialist reviewer for system boundaries — security (attack surface, access control, secrets), data model (schema correctness, migration safety, backwards compatibility), and API contract (interface completeness, versioning, error contract).
frontend-engineerContextual specialist for UI/UX correctness. Launched only when `alignment` or the pre-filter flags that the plan touches UI components, pages, user-facing flows, or interactive state. Absorbs UX review — interaction patterns, accessibility, empty/error states, and user-journey completeness.
frontend-qualityShared frontend taste reference for strategic-implementation. Two tiers — SLIM (legibility/IA, applied to throwaway mockups) and RICH (pixel quality, applied to shipped UI). Owned in-plugin; not a separate skill. Referenced by ui-mockup (slim) and agents/frontend-engineer (rich).
plan-gateTightly-scoped gate agent that filters proposed execution-plan patches against the brief's deliverables and success signal. Default use is post-specialist scope discipline; designed to host additional post-plan gate checks via `mode`.
plan-simplifySingle-pass simplicity reviewer. Runs in parallel with `alignment` against the execution plan and looks for a shorter path to the brief's success signal and per-deliverable validation. Returns either PASS (with minor flags) or ALTERNATIVE (with a described shorter path).
runtime-riskSpecialist reviewer for runtime behavior under load and for supply-chain risk — performance (queries, caching, blocking operations, unbounded resources) and dependencies (necessity, license, maintenance, version pinning).
technical-expertSpecialist reviewer for implementation-level correctness. Identifies libraries, frameworks, and runtimes in the execution plan, surfaces known pitfalls, and catches step-ordering errors or missing integration steps. Does not review tests, boundaries, or runtime risk — those are owned by other specia
testsSpecialist reviewer for validation adequacy. The brief carries user-facing acceptance steps (outcome-only); the execution plan picks the implementation method (preview / CLI / TDD / integration-test / post-hoc). This agent checks that each deliverable's chosen method honestly demonstrates the brief'
user-validationGeneralist reviewer. Stages the brief's named target user and walks every user-acceptance step against the execution plan to find where the user-visible path breaks. Owns PMF, walkthrough, and end-to-end reachability — including the "client-built, pipeline-missing" loophole where UI deliverables loo
