Skills in plugins/colachg/skills/ are auto-discovered — no need to list them in plugin.json.

Install in Claude Code

Push this repo to GitHub, then in Claude Code:

/plugin marketplace add colachg/skills
/plugin install colachg@skills

The marketplace is named skills (see .claude-plugin/marketplace.json) and ships a plugin named colachg, so the install spec is colachg@skills (<plugin>@<marketplace>).

To develop locally without pushing, point the marketplace at the local path:

/plugin marketplace add /Users/colachen/Experiments/GitHub/my-skills
/plugin install colachg@skills

After pushing changes, refresh with:

/plugin marketplace update

Add a new skill

Create a folder under plugins/colachg/skills/ matching the skill name, with a SKILL.md inside:

---
name: my-skill
description: One or two sentences telling Claude exactly when to use this skill. Max 1024 chars.
---

# My Skill

Instructions for Claude go here. Reference supporting files (scripts/, references/)
in the same folder as needed.

Frontmatter rules:

• name: lowercase letters, numbers, and hyphens only; must match the folder name (max 64 chars).
• description: required; this is what triggers the skill, so be specific about when to use it.
• Optional: version, allowed-tools, disable-model-invocation.
