skill-fetch

Cross-platform skill discovery and installation for AI coding agents

Search, score, and install AI agent skills from 9 registries in parallel — works across Claude Code, Cursor, Codex, Gemini CLI, Windsurf, and Amp.

Quick Start

1. Install — pick any method from Installation below
2. Set up API keys — run /fetch-skill-config (interactive, recommended) or configure manually
3. Search & install skills — /fetch-skill react native animation

Features

• 9 Search Sources — SkillsMP (semantic + keyword), GitHub, Anthropic Skills, ClawSkillHub, skills.sh, PolySkill, SkillHub, Skills Directory
• Cross-Platform — Works on 6+ AI coding agents with automatic tool adaptation
• Multi-Variant AI Search — 3 query variants fired in parallel, improving recall significantly
• Quality Scoring — 0-100 composite score: Relevance (40) + Freshness (25) + Community (20) + Trust (15) + External Bonus (5)
• Security Labels — 5 trust tiers: Official, Verified, Partial, Unverified, Security Concerns
• 6-Category Security Scan — Destructive commands, RCE, data exfiltration, system modification, obfuscation, prompt injection
• Prompt Injection Detection — 5 sub-categories (PI-1~PI-5): direct override, hidden role markers, encoding tricks, indirect injection, social engineering
• Integrity Verification — SHA-256 hash recorded at install, tamper detection on future loads
• Paginated Results — Browse 5 at a time with c to continue; install by number from any page
• Local/Global Install — Choose project-level or user-level installation (mandatory prompt)
• Deduplication — Same skill across registries is merged; similar descriptions are flagged
• Bundled API Scripts — Pre-built shell scripts for SkillHub and Skills Directory APIs (no API key exposure)

Installation

Choose the method that fits your setup:

Option 1: Plugin (Best experience, Claude Code)

# Add the skill-fetch marketplace
claude plugin marketplace add girofu/skill-fetch

# Install skill-fetch plugin
claude plugin install skill-fetch@skill-fetch

Provides auto-updates, /fetch-skill command, and full plugin integration.

Option 2: npx skills add (Node.js)

npx skills add girofu/skill-fetch

Works with Claude Code, Cursor, and Codex.

Option 3: curl | sh (Universal, zero dependencies)

curl -fsSL https://raw.githubusercontent.com/girofu/skill-fetch/main/install.sh | bash

Auto-detects installed agents and installs for all of them. Specify a single agent:

curl -fsSL https://raw.githubusercontent.com/girofu/skill-fetch/main/install.sh | bash -s -- --agent claude

Option 4: Python installer

python3 -c "$(curl -fsSL https://raw.githubusercontent.com/girofu/skill-fetch/main/install.py)"

Or download and run:

curl -fsSL https://raw.githubusercontent.com/girofu/skill-fetch/main/install.py -o install.py
python3 install.py --agent cursor

Option 5: Manual (git clone)

git clone https://github.com/girofu/skill-fetch.git
# Claude Code
cp -r skill-fetch/skills/skill-fetch ~/.claude/skills/skill-fetch

# Cursor
cp -r skill-fetch/skills/skill-fetch ~/.cursor/skills/skill-fetch

# Other agents: replace ~/.cursor/ with ~/.codex/, ~/.gemini/, ~/.windsurf/, or ~/.amp/

⚙️ Setup API Keys

Important: API keys unlock the full 9-source search. Without them, only Sources 3-8 are available (still useful, but fewer results).

Interactive Setup (Recommended)

Run /fetch-skill-config in Claude Code. It will:

• Show which keys are currently configured
• Walk you through setting each key with links to get them
• Automatically install the SkillsMP MCP server if needed
• Write everything to ~/.claude/skills/.fetch-config.json

Manual Setup

🔑 SkillsMP API Key (Sources 1-2) — Recommended

SkillsMP provides the best semantic search with AI-powered matching. Get your free API key:

1. Go to skillsmp.com and create an account
2. Copy your API key
3. Register the MCP server:

claude mcp add --scope user skillsmp -- npx -y skillsmp-mcp-server --env SKILLSMP_API_KEY=your_key_here

4. Restart Claude Code — SkillsMP tools will be available in the next session

🔑 SkillHub & Skills Directory (Sources 8-9) — Optional

For additional coverage, create ~/.claude/skills/.fetch-config.json:
