How it works

Skills are directories placed under ~/.claude/skills/ that Claude Code reads at startup. CCSM manages these directories by pulling skill definitions from marketplace repositories that expose a skills.json manifest:

{
  "name": "My Marketplace",
  "skills": [
    {
      "name": "example-skill",
      "description": "An example Claude Code skill",
      "repository": "https://github.com/user/skill-repo",
      "branch": "main"
    }
  ]
}

Creating a skill marketplace

A marketplace is simply a public Git repository that contains a skills.json manifest at its root. CCSM reads this file to discover what skills are available.

Repository structure

your-marketplace-repo/
  skills.json        ← manifest (required)
  README.md          ← optional landing page

skills.json format

{
  "name": "My Marketplace",
  "version": "1.0.0",
  "skills": [
    {
      "name": "my-skill",
      "description": "A short description shown in search results",
      "repository": "https://github.com/user/skill-repo",
      "branch": "main"
    },
    {
      "name": "another-skill",
      "description": "A skill that lives in a monorepo subdirectory",
      "repository": "https://github.com/user/monorepo",
      "branch": "main",
      "path": "skills/another-skill"
    }
  ]
}

Field	Required	Description
name	Yes	Marketplace display name
version	No	Arbitrary version string for your own tracking
skills	No	Array of skill entries (defaults to [])

Skill entry fields:

Field	Required	Description
name	Yes	Unique skill identifier (used with ccsm install <name>)
description	Yes	One-line summary shown in ccsm search output
repository	Yes	Public Git repository URL for the skill
branch	No	Git branch to install from (defaults to main or master, auto-detected by the marketplace host)
path	No	Subdirectory within the repository where the skill files live — use for monorepos hosting multiple skills

What goes in a skill repository

Each skill repository (the one referenced by repository) is a standard Claude Code skill directory. At minimum it should contain one of:

• SKILL.md — the skill manifest (preferred)
• CLAUDE.md — alternative manifest filename
• Supporting files referenced by the manifest (scripts, templates, etc.)

See the Claude Code skills documentation for details on writing skill manifests.

Publishing your marketplace

1. Create a public Git repository with a skills.json following the format above.
2. Push it — make sure skills.json is at the repository root.
3. Anyone can register it with:

ccsm marketplace add https://github.com/your-username/your-marketplace

CCSM fetches skills.json from the raw main or master branch automatically, so both of those branch names work out of the box.

Deploy modes

• Copy (default): Skill files are physically copied to ~/.claude/skills/<name>/.
• Link: A symlink is created from ~/.claude/skills/<name>/ to the local store, useful for development.

Building

cargo build --release

Cross-compilation targets: Linux (amd64), macOS (amd64), and Windows (amd64) via cargo-zigbuild.
