What problem does it solve? Plans that are never scored or challenged tend to survive review by accident rather than merit, leading to ungrounded or incomplete implementations. This Skill turns plan-writing into a closed loop: draft or reuse a plan, score it 0-100 against a rubric, iterate until it clears 90, get advisor sign-off, then implement and update docs. ## Core Features & Use Cases - Rubric-based scoring: Evaluates plans across six weighted axes including evidence grounding, concreteness, risk/reversibility, test coverage, and scope discipline. - Advisor gate: Requires an external advisor review after self-scoring, with objections reopening the iteration loop. - Repo-aware conventions: Reads .harness/config.json for plan directories, dimensions, and verification commands, degrading gracefully to generic templates when absent. - Use Case: Before implementing a non-trivial feature, invoke the Skill to draft a plan citing concrete path:line evidence, iterate it past a 90-point threshold with advisor approval, then implement following the repo's operating contract. ## Quick Start Ask the assistant to run planmax on your task, for example by saying "plan it out and score it" for the feature you want to implement.
