ckills

A thin Typer wrapper over npx skills that installs skills into Claude Code plugin directories.

The problem

npx skills installs Claude Code skills to ./.claude/skills/<name>/ at the current working directory. It has no flag to redirect the target.

A Claude Code marketplace repo holds many plugins, each with its own skills/ directory at <plugin>/skills/<name>/. Running npx skills at the repo root drops the skill in the wrong place; running it inside a plugin creates <plugin>/.claude/skills/… which the plugin manifest doesn't see.

The idea

ckills runs npx skills add in a temporary directory, then moves each produced skill into <plugin>/skills/. Plugin directories are auto-discovered (presence of .claude-plugin/plugin.json or an existing skills/ dir). skills-lock.json is discarded — plugin dirs track skills as plain files.

Quick start

Requires Python >=3.11, uv, and npx (Node.js).

uv sync
uv run ckills list-plugins
uv run ckills list-available vercel-labs/agent-skills
uv run ckills install marimo-plugin marimo-team/marimo-pair --skill marimo-pair

Commands

All commands accept --root PATH to point at a marketplace repo other than the enclosing git repo.

Example

my-marketplace/
├── marimo-plugin/
│   ├── .claude-plugin/plugin.json
│   └── skills/
├── notebook-plugin/
│   └── skills/
└── (etc.)

$ cd my-marketplace
$ ckills list-plugins
marimo-plugin
notebook-plugin

$ ckills install marimo-plugin marimo-team/marimo-pair --skill marimo-pair
✓ marimo-pair → marimo-plugin/skills/marimo-pair
