skillhub

Trusted skill marketplace for AI agents. One manifest, many runtimes.

MIT v0.2.0 254 skills 15 MCP tools + resources 4 curated collections

A skill is a small tool that an AI agent can call as a black box. skillhub is the registry where maintainers publish once and any agent can discover, install, and run.

Why

• Maintainers write skill.yaml once — the CLI compiles to the runtime's native layout.
• Agents find skills via skillhub search --json instead of scraping the web.
• Humans see a trust_score per skill — derived from real signals, not star counts.
• Everyone agrees on the same schema, so we don't fork five copies of the same SKILL.md across runtimes.

Install

git clone https://github.com/djmarat/skillhub
cd skillhub
uv tool install -e .            # installs skillhub + skillhub-mcp
skillhub search "pdf"

Requires uv (brew install uv on macOS). The CLI is then globally available as skillhub.

Usage

# Search — human table
skillhub search "search"

# Search — agent-friendly JSON
skillhub search "pdf" --json

# Show full details
skillhub show pdf-md

# Install into a runtime
skillhub install pdf-md -r hermes
skillhub install pdf-md -r claude-code
skillhub install pdf-md -r codex
skillhub install pdf-md -r cursor

# Validate your own skill.yaml
skillhub validate ./my-skill/skill.yaml

For AI agents — MCP server

Every modern AI agent (Claude Code, Hermes, Codex, Cursor) speaks MCP. skillhub ships its own marketplace as an MCP server, so the agent can search, show, stats, probe, install, update, uninstall, validate, rate, recommend and profile skills as ordinary tool calls — no copy-paste, no scraping.

Once installed, ask your agent: "find a tool for converting PDFs" — it will call skillhub.search, surface the best matches, and after running them call skillhub.rate. The next session sees your agent's history via skillhub.profile and improves recommendations. This is the loop that keeps agents coming back.

Roadmap

• v0.1 — schema freeze, security scanner v1, real registry updater.
• v0.2 — trust score from real install_success_rate telemetry.
• v0.3 — in-agent MCP server (skillhub-mcp) for tool-call discovery.
• v1.0 — featured/verified tiers, paid placements, the actual marketplace.
