model-implementerAutonomous code implementation agent. Reads a PLAN.md and implements every step: writes code, creates files, runs tests. Designed for handoff from a planner agent. Uses the most cost-efficient model available.
model-plannerSenior architect agent that analyzes tasks and creates detailed step-by-step implementation plans. Used as the planning phase in multi-model pipelines before handing off to an implementer agent.
model-reviewerCode review agent that evaluates implementation changes against a plan. Checks correctness, security, quality, and test coverage. Outputs a structured PASS/FAIL verdict. Used as the final quality gate in multi-model pipelines.
model-routerTask routing agent that decides which model or pipeline mode to use for a given task. Routes to single-agent (Claude or Codex), dual-mode (plan-implement-review), or custom agent teams based on task complexity and type.
