What problem does it solve? Managing a personal library of Agent Skills across machines is error-prone: edits lack review, README indexes drift out of sync, and Git commits or global installs are easy to forget. This Skill standardizes the entire add-or-update workflow so every change is diffed, confirmed, committed, and optionally synced to global tool directories. ## Core Features & Use Cases - Structured 7-phase workflow: requirement breakdown, target skill location, draft generation with mandatory unified diff display, single confirmation prompt, file write, Git commit/push, and global sync to Codex or Cursor skill directories. - Slash-command parsing: /manage-skills 【bugfix】 ... treats bracketed or slashed names as update targets rather than executable skills, preventing accidental skill invocation. - Check-and-sync mode: "检查skills" fetches remote state, performs safe fast-forward pulls, and optionally syncs skills to global directories via symlink or copy. - Use Case: You want to add a bilingual commit-message rule to your bugfix skill. Say /manage-skills 【bugfix】commit subject 要中英文双语 and the Skill shows a diff, writes the file, and asks once whether to commit, push, and sync globally. ## Quick Start Say "/manage-skills 【bugfix】 add a rollback verification step" to update the bugfix skill with a reviewed diff and optional Git commit.
