What is AgentSkillsHub?

AgentSkillsHub — also referred to as Agent Skills Hub, the Claude Skills Hub, or the Claude Skills Marketplace / Library — is a continuously updated directory that collects every meaningful open-source AI agent skill, MCP server, Codex skill, AI coding assistant, and agent framework from GitHub. Each project is:

• Classified into one of 7 categories (mcp-server, claude-skill, codex-skill, agent-tool, prompt-library, ai-coding-assistant, uncategorized)
• Scored on 10 weighted signals and 6 quality dimensions (completeness, clarity, specificity, examples, README structure, agent readiness)
• Compared side-by-side through the /compare/ feature and /best/{scenario}/ landing pages
• Refreshed every 8 hours via an automated GitHub Actions pipeline

The goal: if you are building with Claude Code, Cursor, Windsurf, Cline, OpenAI Codex, or any agentic IDE, you should be able to find the right MCP server or Claude Skill in under 30 seconds — without spelunking through random GitHub topics.

               (6 phases)    (classify)   (6 dimensions)  (0-100)    (Web + API)

Layer	Stack
Backend	Python 3.12 · FastAPI · SQLAlchemy · httpx
Frontend	React 18 · TypeScript · Vite · TailwindCSS v4
Database	Supabase (PostgreSQL) / SQLite (local)
Deploy	GitHub Pages + GitHub Actions (every 8h)
Email	Resend API · Supabase pg_net

Data Pipeline

1. Collection (scheduler/jobs.py)

Every 8 hours, GitHub Actions triggers a 6-phase sync:

Phase	What	Budget
Search	10+ GitHub queries (mcp-server, claude-skill, agent-tool...)	~30
Masters	Fetch repos from verified skill creators	~18
Extra	Community-submitted + curated repos	~14
Enrich	Owner profiles (followers)	≤500
README	Full README content (≤50KB each)	≤300
Upsert	Clean → score → save	0

• Incremental sync on weekdays (only new/updated repos), full sync on Sundays
• Smart rate-limit handling: waits for actual GitHub reset time

2. Cleaning (services/data_cleaner.py)

• Deduplication by repo_full_name
• Keyword-based category classification: mcp-server · claude-skill · codex-skill · agent-tool · ai-skill · llm-plugin · youmind-plugin
• Project type inference (framework / skill / tool)
• Size categorization (micro ≤50KB → large >5MB)

3. Evaluation

Quality Analysis — 6 dimensions (services/quality_analyzer.py):

Dimension	Weight	Key Signals
Completeness	15%	README size, license, description, stars
Clarity	15%	Description quality, topics, naming
Specificity	15%	Language, topic count, category, size
Examples	12%	Code examples, commits, contributors
README Structure	23%	Sections, code blocks, badges, TOC
Agent Readiness	20%	API docs, config, install, MCP compliance

Composite Score — 9 weighted signals (services/scorer.py):

Signal	Weight	Method
Quality	20%	6-dimension aggregate
Stars	18%	log₁₊ₓ normalization
Recency	11%	Exponential decay e⁻⁰·⁰¹ᵈ
Forks	10%	log₁₊ₓ
Commits	10%	log₁₊ₓ
Issue Resolution	10%	resolved / total
Momentum	8%	Z-score star growth
Author Followers	8%	log₁₊ₓ
Size Bonus	5%	Smaller = higher

Also: Platform Inference (17 platforms), Token Estimation, Composability (TF-IDF + 8-signal skill pairing).

4. Presentation

Dual-mode API client: Production uses Supabase PostgREST + RPCs directly; dev uses FastAPI backend.

Key optimizations:

• get_landing_data() RPC replaces 7+ API calls
• Database views: v_trending, v_top_rated, v_rising, etc.
• Full-text search via PostgreSQL tsvector + GIN index
• HTTP caching: 5min (trending) → 1hr (stats)
