Agents

Core agents

• lead: default free-form router, feature orchestrator, and phase-barrier owner.
• scoper: lightweight research -> spec orchestrator.
• designer: uses PRODUCT.md/DESIGN.md, optional Impeccable, and Open Design.
• researcher: verifies code, docs, APIs, alternatives, and risks.
• specifier: produces specs, tasks, acceptance criteria, and validation plans.
• developer: implements approved tasks, including direct-mode work delegated by lead, and validates changes.
• reviewer: reviews diffs against spec and returns verdicts.

Optional AHE sidecars

• evaluator: captures benchmark/smoke evidence.
• debugger: turns results and traces into root causes.
• evolver: proposes harness changes only with evidence.

Sidecars are not part of the normal feature flow.
