One copy of every Skill, linked into every project.

SkillStash clones Skill repos into one git repo you own and symlinks each Skill into the projects you pick. Pull that repo once to update every project. Git never sees the symlinks.

Set up SkillStash

1Pick public Skill repos

The same Skills, cloned into every repo.

One repo of Skills, linked into every project.

One pull updates every linked project.

Each project pulls its own copy, so atlas-web and billing-api end up on different commits of frontend-design, and both copies go into git.

Each source repo is a submodule of one git repo you own. Each project gets a symlink to the Skill, and git ignores the symlink.

A symlink points at the files in your Skills repo, so it shows the new commit once the pull finishes. A copy is its own folder, and a pull never touches it.

Commit your own Skills. Link everyone else's.

Skills you write, and copies you edit, go into the project's git history like any other file. Third-party Skills are symlinks into your Skills repo, and SkillStash lists each one in the project's .git/info/exclude, so git ignores them.
