Install

npx -y skills add cytoph/agent-skills --skill update-git-skills

Assembled from the repository path, not quoted from the project. Check it against their README if it does not work.

One thing to look at

0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Use when updating externally-sourced skills from Git repositories in the current project or user-level .claude/skills directory. Use when skills may be outdated or after adding a new .gs-meta source file.

The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

Update Git Skills

Checks *.gs-meta source files against their upstream Git repos and downloads updates when the SHA has changed.

Parameters

Parameter	Description
(none)	Update all sources in `pwd/.claude/skills`
`--global`	Update all sources in `~/.claude/skills`
`--only=name1,name2`	Limit to named sources (matches the `.<name>.gs-meta` filename)

Usage

Run the script, passing any parameters the user provided:

bash ~/.claude/skills/update-git-skills/update.sh [--global] [--only=name1,name2]

After updating, reload skills in your agent (e.g. /reload-plugins for Claude Code).

Adding a Skill Source

Create a .<name>.gs-meta file in .claude/skills/:

repo=owner/repo
path=relative/path/to/skills/folder
sha=
allow=folder1,folder2

repo — GitHub shorthand (owner/repo) or full Git URL (https://gitlab.com/owner/repo, git@...)
path — subfolder within the repo whose contents are copied to .claude/skills/
sha — leave empty on first add; filled in automatically after install
allow — (optional) comma-separated folder names to install; all others skipped
deny — (optional) comma-separated folder names to skip; all others installed

Only one of allow or deny may be set. If both are present the script logs an error for that source and continues with the others.

Example — .gws-cli.gs-meta:

repo=googleworkspace/cli
path=skills
sha=
allow=gws-gmail,gws-calendar

Notes

Only tracks the main branch
Uses git ls-remote for SHA check (no download if already up to date)
Clones with --filter=blob:none where supported; falls back to plain --depth 1
Skills from different repos sharing a folder name will overwrite each other — avoid naming conflicts
This skill itself is not managed by the script
