update-skills

# About Each skill is a self-installing additive unit: its folder under `.claude/skills/<name>/` carries its own apply steps (`SKILL.md`), and channel/provider skills fetch their code files from a long-lived upstream branch (`channels`, `providers`) with `git fetch origin <branch>` + `git show origin/<branch>:path > path`. Every apply is idempotent and safe to re-run. Updating a skill means **re-running its own apply**. The apply re-fetches the latest files from upstream and overwrites the copied-in code, so newer versions land additively. Run `/update-skills` in Claude Code. ## How it works **Preflight**: checks for a clean working tree and the upstream remote. **Detection**: reads the channel and provider barrels to list which skills have copied code into your tree, and lists the operational/utility skills present under `.claude/skills/`. **Selection**: presents the installed skills and lets you pick which to re-apply. **Re-apply**: invokes each selected skill's own apply (e.g. `/add-slack`), which fetches its latest files. Then validates with build + test. --- # Goal Help users pull the latest skill code from upstream by re-applying their installed skills, without losing local customizations and without merging any branch. # Operating principles - Never proceed with a dirty working tree. - Re-apply each skill through its own idempotent apply step — re-applying overwrites only that skill's code files; credentials, wiring, and DB state are untouched. - Keep token ...
