Stuffbucket Skills

On-demand skills for AI agents. Instead of stuffing every capability into the context window, agents discover and load only what they need — via a 2-tool MCP server that scales to any number of skills at constant cost.

Works with Claude, Copilot, and any MCP-compatible client.

Quick Start

Add the MCP server to any client:

{
  "mcpServers": {
    "skill-router": {
      "command": "npx",
      "args": ["-y", "@stuffbucket/skills"]
    }
  }
}

Or install as a plugin marketplace:

# Claude Code
/plugin marketplace add stuffbucket/skills

# Copilot CLI
/plugin marketplace add stuffbucket/skills

That's it. Your agent can now discover and load skills on demand.

How It Works

The skill-router exposes two tools — list_skills and get_skill — instead of registering every skill separately. Agents search by intent, load what they need, and the context window cost stays constant.

Each skill is a self-contained package: a SKILL.md with instructions plus optional scripts/, references/, and assets/. Skills are authored once by an expert and delivered automatically to anyone whose agent needs them.

Create a Skill in 5 Minutes

Anyone can contribute a skill. The entire workflow is scaffold → edit → validate → submit:

# 1. Scaffold
npm run new -- my-new-skill

# 2. Edit the generated SKILL.md
#    - Set `name` and `description` in the frontmatter (this is what triggers the skill)
#    - Write instructions in the body (what the agent needs to know)
#    - Add scripts/, references/, or assets/ if needed

# 3. Validate
npm run validate:one -- plugins/stuffbucket/skills/my-new-skill

# 4. Package and submit
npm run package -- plugins/stuffbucket/skills/my-new-skill
# Open a "New skill" issue and attach the .skill file — CI validates and opens a PR

Key principles (from the skill-creator guide):

• The agent is already smart. Only include knowledge it doesn't have — specific workflows, schemas, tool integrations, domain expertise.
• Context window is a public good. Keep SKILL.md under 500 lines. Split large content into references/ files.
• Match freedom to fragility. Text instructions for flexible tasks, executable scripts for brittle ones.
