What Is OpenAgentSkill?

OpenAgentSkill is a public index for finding, comparing, auditing, and recommending AI agent skills.

The product is built for three audiences:

The long-term goal is to become the trust and routing layer for agent skills: not just a directory, but the place where humans and agents can decide what is safe, useful, maintained, and worth installing.

Product Surfaces

README Badges For Skill Authors

[![OpenAgentSkill Trust](https://www.openagentskill.com/api/badge/crawl4ai?metric=trust&label=Trust)](https://www.openagentskill.com/skills/crawl4ai)
[![OpenAgentSkill Audit](https://www.openagentskill.com/api/badge/crawl4ai?metric=audit&label=Audit)](https://www.openagentskill.com/skills/crawl4ai/audit)
[![OpenAgentSkill Quality](https://www.openagentskill.com/api/badge/crawl4ai?metric=quality&label=Quality)](https://www.openagentskill.com/skills/crawl4ai)

Replace crawl4ai with the skill slug.

Auto-Discovery

The indexer scans GitHub for high-signal skill repositories and imports approved matches.

Current import rules:

• Minimum GitHub stars are controlled by INDEXER_MIN_STARS.
• Per-run target is controlled by INDEXER_RUN_TARGET.
• Search budget is controlled by INDEXER_MAX_SEARCH_REQUESTS.
• MCP and Model Context Protocol repositories are excluded from automated imports.
• Production indexer routes require INDEXER_SECRET.

Useful routes:

# Run the indexer with automation auth
POST /api/indexer/run

# Inspect recent import summaries
GET /api/indexer/logs

# Refresh GitHub star counts
POST /api/indexer/refresh-stars
