Audit and optimize one or more existing Agent Skills from a canonical source path, then bump semver, update README/SKILL.md/skill.yaml/CHANGELOG.md, and verify installed copies and catalog synchronization. Checks frontmatter, trigger quality, CLI hygiene, accurate and concise naming, portability, version drift, dirty worktrees, shared Skill feedback policy, and compatibility contracts. Use when the user asks to optimize, refine, audit, polish, or update a Skill, or mentions "优化 skill", "skill 审计", "刷一遍 skill", "skill-optimizer", or "update skill changelog".
