Chris’s Skills Marketplace

A personal Claude Code marketplace bundling skills and plugins I rely on day-to-day — driving Iris architecture knowledge, filing NZ taxes, tracking timesheet hours, converting PDFs to ebooks, coaching my own prompts, coaching a 13-year-old through math homework, plus the Campaign Mode quest framework, its Six Animals advisory council, and the Mitchell Agentic Sprint validation pipeline.

What’s in here

The first twelve plugins ship from this repository — each one is a skill directory under skills/ that the marketplace lists as a separately-installable plugin. The last three are listed for convenience and source from their own repos.

Quick Start

Claude Cowork and Claude Code Desktop

1. From either the Cowork or Code tab in Claude Desktop, select + → Plugins → Add plugin.
2. Add marketplace — Select the By Anthropic dropdown, then select Add marketplace from GitHub and enter:

   https://github.com/cgbarlow/skills
   

3. Install plugins — find and install whichever plugins you want from the marketplace. Each one is independent — install just iris, just timesheet, or all fifteen.

Claude Code CLI

1. Install Claude Code (full guide):

   curl -fsSL https://claude.ai/install.sh | bash
   

2. Add the marketplace — in a Claude Code session:

   /plugin marketplace add cgbarlow/skills
   

3. Install the plugin you want (one at a time, or repeat for multiple):

   /plugin install iris@cgbarlow-skills
   /plugin install ir3-tax-return@cgbarlow-skills
   /plugin install timesheet@cgbarlow-skills
   /plugin install pdf-to-ebook@cgbarlow-skills
   /plugin install agentic-coach@cgbarlow-skills
   /plugin install flow-coach@cgbarlow-skills
   /plugin install math-coach@cgbarlow-skills
   /plugin install doview-outcomes-answer@cgbarlow-skills
   /plugin install doview-image-retriever@cgbarlow-skills
   /plugin install askuserquestion@cgbarlow-skills
   /plugin install campaign-mode@cgbarlow-skills
   /plugin install six-animals@cgbarlow-skills
   /plugin install mitchell-agentic-sprint@cgbarlow-skills
   

   For the Mitchell Agentic Sprint specifically, you need all three of six-animals, campaign-mode, and mitchell-agentic-sprint — the Sprint depends on the other two for its NPC infrastructure.

4. Reload so the new skills are picked up by your current session:

   /reload-plugins
   

That’s it. After install, the skills trigger automatically — you don’t need to type their names. Say “use iris to search for payments” and the iris skill triggers. Say “I need to file my IR3” and ir3-tax-return triggers. List loaded skills any time with /skills.

Repository layout

skills/
├── .claude-plugin/

├── skills/                  # the skills the marketplace serves

└── skills-standalone/       # packaged .skill bundles (zip archives) for distribution outside the marketplace
    └── .skill         # one per skill above (iris.skill, timesheet.skill, …)

Each marketplace entry lists the skill via "skills": ["./skills/"], mirroring anthropics/skills. skills-standalone/ holds .skill files — zip archives of a skill’s full directory — for sharing a single skill outside the marketplace clone. Installing a plugin clones the whole repo but loads only the named skill — fine on disk, and means each skill can be installed individually without forcing the whole bundle.

Contributing a new skill

1. Use skill-creator to scaffold the skill (it’ll write a SKILL.md and evals).
2. Drop it in skills//.
3. Add an entry to .claude-plugin/marketplace.json with "source": "./" and "skills": ["./skills/"].
4. Mention it in this README’s table.

Each plugin carries its own license metadata in the marketplace listing. The default is CC-BY-SA 4.0 unless otherwise noted in the individual plugin directory.
