What problem does it solve?
It solves the problem of turning an unclear or multi-step goal into a complete, verifiable implementation workflow without repeatedly interrupting the user—by generating a requirements spec, executing it, evaluating results with acceptance checks, and performing bounded fixes when failures occur.
Core Features & Use Cases
- End-to-end loop orchestration: Performs interview/spec creation, execution via Codex, evaluation via automated checks plus a judge review, and up to two fix iterations when blockers or major issues are found.
- Acceptance-criteria driven delivery: Requires an auto-executable acceptance criteria section (CMD/METRIC) and runs those checks to determine pass/fail.
- Autonomous vs collaborative control: Defaults to autonomous execution that minimizes user involvement, while supporting a collaborative mode that prompts the user for step-by-step confirmations.
- Role-symmetric guardrails: Uses Claude as planner/judge and Codex as executor/fixer, ensuring Claude does not directly modify code during review/fix decisions.
Quick Start
Use ultra-plan when you want the assistant to clarify requirements and then automatically execute, test, review, and (if needed) fix the work until it produces a final report for your task.
