Claude Code plugin that runs three coordinated sessions — Planner, Generator, and Evaluator — pairing Claude with OpenAI Codex as an independent second reviewer in planning and evaluation. You approve the spec, then the Generator implements and the Evaluator verifies in a loop until it passes, with no manual review or copy-pasting in between. Built on the insight that a separate skeptical evaluator catches bugs a session misses in its own work.

Generate code from specs with automated quality gates before returning
Multi-file refactoring with planner review before implementation
Validate generated test suites against coverage requirements

Usable rating — This tool is functional but has notable gaps. Review the evaluation notes below before deploying.

Why it matters

Structures multi-step code generation workflows (planning, generation, evaluation) to reduce hallucination and improve code quality in Claude AI–assisted development. Reduces manual iteration cycles by enforcing a critique loop before output.

Best for

Teams building code generation features or using Claude for complex, multi-file refactoring where plan validation before execution matters.

Things to check

Not recommended for simple, small, or mechanical tasks — the multi-session Planner/Generator/Evaluator loop uses more tokens than a regular Claude session. Requires paid subscriptions to both Claude Max and ChatGPT. Small project (34 stars); scored from public trust signals, not hands-on tested.
Single maintainer. Consider the risk if this person stops maintaining the project.
