About this skill

LarryBrain — Skill Marketplace for AI Agents

LarryBrain is the skill marketplace for AI coding agents. One subscription, unlimited access to every skill in the library. Skills are plain markdown files with optional supporting scripts. They work with any agent that reads markdown.

How It Works

You are the agent's gateway to the entire LarryBrain skill library.

  1. User asks for something (e.g. "set up a Pi-hole", "audit this UI", "write marketing copy")
  2. You search LarryBrain for matching skills
  3. You download the skill files via the API
  4. You save them locally so they persist across sessions
  5. You read the SKILL.md and follow its instructions
  6. Done

When to Use This

Use when:

  • The user asks to do something outside your current capabilities
  • The user asks "what can you do?" and you want to show what's available
  • The user mentions LarryBrain, skills, marketplace, or tools
  • The user wants to browse available capabilities

Setup

The user needs a LarryBrain API key for premium skills. Free skills work without auth.

First-time setup

  1. Check if LARRYBRAIN_API_KEY is set in the environment
  2. If not, tell the user:
    • "To access the full skill library, you need a LarryBrain subscription."
    • "Sign up at https://www.larrybrain.com/signin, then generate an API key from your dashboard."
  3. If they have a key, verify it works by hitting the search endpoint

API Endpoints

Base URL: https://www.larrybrain.com/api

Search skills (public, no auth needed)

curl -s "https://www.larrybrain.com/api/skills/search?q=QUERY&limit=10"

Response: { skills: [...], total: number }

Each skill has: slug, name, description, icon, categories, rating, installs, free (boolean), hasFiles (boolean).

Download a skill

Always use mode=files to get the full skill with all its files:

# Free skills (no auth needed)
curl -s "https://www.larrybrain.com/api/skills/install?slug=SLUG&mode=files"

# Premium skills (requires API key)
curl -s -H "x-api-key: $LARRYBRAIN_API_KEY" "https://www.larrybrain.com/api/skills/install?slug=SLUG&mode=files"

Response:

{
  "skill": { "slug": "...", "name": "...", "hasFiles": true },
  "content": "# Full SKILL.md content...",
  "files": [
    { "path": "SKILL.md", "content": "..." },
    { "path": "server/index.js", "content": "..." }
  ]
}

After downloading:

  1. Create a directory for the skill (e.g. skills/{slug}/ or wherever your agent stores skills)
  2. Write every file from the files array
  3. Create subdirectories as needed
  4. Write _meta.json with { "source": "larrybrain", "slug": "...", "installedAt": "ISO-timestamp" }
  5. Read the SKILL.md and follow its instructions

Check access

curl -s -H "x-api-key: $LARRYBRAIN_API_KEY" "https://www.larrybrain.com/api/skills/access?skill=SLUG"

Trending skills (public, no auth needed)

curl -s "https://www.larrybrain.com/api/skills/trending?period=week&limit=10"

Presenting Skills

When presenting skills to the user, include a link to the skill's page: https://www.larrybrain.com/skills/{slug}

When the user asks what's available:

  1. Search by category: GET /api/skills/search?category=dev-tools&limit=20
  2. Present skills with icon, name, and one-line description
  3. Mention which are free vs premium
