Marketplace

External skill marketplace with 100K+ agent skills

Skill Marketplace

CLEO integrates with the Agent Skills Marketplace (agentskills.in API) for discovering and installing external skills from a marketplace of 100,000+ agent skills.

API Endpoint: CLEO uses agentskills.in as the public API endpoint. No API key required for search and discovery.

Quick Start

# Search for skills
cleo skills search "rust" --mp

# View skill details
cleo skills search "authentication" --mp --human

# Install a skill
cleo skills install @wshobson/rust-async-patterns --mp

Available Commands

Search Skills

# Search SkillsMP marketplace
cleo skills search "query" --mp

# Search with human-readable output
cleo skills search "query" --mp --human

# Search both local and SkillsMP
cleo skills search "query" --source all

Example Output:

{
  "success": true,
  "query": "rust",
  "source": "skillsmp",
  "counts": {
    "local": 0,
    "skillsmp": 10,
    "total": 10
  },
  "skills": [
    {
      "name": "rust-async-patterns",
      "author": "wshobson",
      "stars": 25798,
      "description": "Master Rust async programming...",
      "source": "skillsmp",
      "scopedName": "@wshobson/rust-async-patterns",
      "repoFullName": "wshobson/agents"
    }
  ]
}

Workflow Example

Finding Skills for a Project

Scenario: “Build a Rust calculator CLI”

# 1. Search for Rust skills
cleo skills search "rust cli" --mp --human

# Results show:
#   @wshobson/rust-async-patterns (25798★)
#   @wshobson/memory-safety-patterns (25798★)

# 2. Search for CLI patterns
cleo skills search "cli argument parsing" --mp --human

# 3. Install relevant skills
cleo skills install @wshobson/rust-async-patterns --mp

# 4. Use the skill
@skills/mp/rust-async-patterns/SKILL.md
Build a calculator CLI in Rust.

Recipe Discovery

For complex projects, search multiple skill categories:

# Authentication project
cleo skills search "authentication" --mp
cleo skills search "jwt oauth" --mp
cleo skills search "security audit" --mp

# Combine into workflow
# 1. ct-research-agent researches requirements
# 2. ct-spec-writer creates specification
# 3. External auth skill guides implementation
# 4. External security skill audits result

Configuration

Cache Settings

API responses are cached to reduce network calls:

# Cache location
~/.cleo/.skills-cache/

# Cache TTL
# Search results: 5 minutes
# Skill content: 1 hour

Optional Configuration File

Create .cleo/skillsmp.json for advanced settings:

{
  "_meta": {
    "schemaVersion": "1.0.0"
  },
  "enabled": true,
  "cacheDir": "${HOME}/.cleo/.skills-cache"
}

Configuration is optional. The API works without any configuration file.
