skill-evolve

v0.2.1

Skill Evolution Engine — Darwin-style autonomous SKILL.md optimizer. Applies a 9-dimension rubric (60 structural + 40 effectiveness; structure now elevates the three SkillLens-validated high-signal dimensions — failure-mechanism encoding / executable specificity / high-risk-action blacklist — that lift pairwise judge accuracy 46.4%→73.8%), default multi-judge independent scoring, mandatory with-skill-vs-no-skill baseline comparison (negative-transfer is a hard non-ship gate), and git-backed ratchet hill-climbing (keep-or-revert) to evolve any Claude Code skill from initial draft toward 90+. Ports SkillOpt's three stability controls: rejected-edit buffer (dead-ends.md) + slow-update memory (learnings.md) + text learning-rate (≤30-line edit budget). Inspired by Karpathy's autoresearch, alchaincyf/darwin-skill, and Microsoft SkillLens/SkillOpt.

skill-evolveskills/skill-evolve/SKILL.md

Skill Evolution Engine —— 任意 SKILL.md 的自主进化器。对目标 skill 执行「9 维 rubric 评分（含 SkillLens 验证的失败机制/可执行性/高风险黑名单三高信号维 + 带 skill vs 无 skill 基线对比）→ 聚焦改进 → 独立 subagent 复评 → 棘轮保留/回滚」循环，把一个能跑的 skill（~60 分）打磨到生产可交付（≥90 分）。 Use when: (1) 用户说"优化这个 skill"/"让这个 skill 变好"/"evolve skill", (2) 新写的 SKILL.md 需要质量提升, (3) 已有 skill 在实战中表现不稳要回炉, (4) 批量提升一个目录下所有 skill 的质量水位线。 Triggers: "优化 skill", "进化 skill", "improve skill", "evolve skill", "skill 变好", "skill-evolve", "darwin", "ratchet skill", "skill 调优"
