Terms of Service

Last updated: March 9, 2026

1. Acceptance

By accessing or using OpenSkill ("the Platform"), you agree to these Terms of Service. If you do not agree, do not use the Platform.

2. What OpenSkill Is

OpenSkill is an open-source platform for discovering, installing, and publishing AI coding agent skills. The Platform consists of a web platform and a command-line tool (osk). Skills are instruction files that extend the capabilities of AI coding agents such as Claude Code, Cursor, Codex, and Antigravity.

3. Accounts

You may sign in using your GitHub account. You are responsible for all activity under your account. You must not share your API tokens or credentials. The Platform may suspend or terminate accounts that violate these Terms.

4. Publishing Skills

When you publish a skill, you represent that:

  • You have the right to publish the content.
  • The skill does not contain malicious code, credential-harvesting logic, data exfiltration patterns, or destructive commands.
  • The skill complies with its stated license.

All published skills are subject to automated security auditing. The Platform may suspend or remove skills that fail audit checks or violate these Terms, without prior notice.

5. User Content

You retain ownership of content you publish (skills, reviews, profile information). By publishing content on the Platform, you grant OpenSkill a non-exclusive, worldwide license to host, display, and distribute that content as part of the Platform's operation.

6. GitHub-Discovered Skills

The Platform indexes publicly available SKILL.md files from GitHub repositories. These skills are displayed as-is and are governed by their respective repository licenses. OpenSkill does not claim ownership of discovered skills. Repository owners may request removal by contacting us.

7. Acceptable Use

You agree not to:

  • Publish skills designed to exfiltrate data, steal credentials, or cause harm.
  • Circumvent security audits or content moderation.
  • Abuse the API or CLI with excessive automated requests.
  • Impersonate other users or misrepresent skill authorship.

8. No Warranty

The Platform and all skills are provided "as is" without warranties of any kind. OpenSkill does not guarantee that skills are safe, functional, or fit for any particular purpose. You install and use skills at your own risk. The automated security audit is a best-effort check, not a guarantee of safety.

9. Limitation of Liability

To the maximum extent permitted by law, OpenSkill and its contributors shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Platform or any skill installed through it.

10. Changes

We may update these Terms at any time. Continued use of the Platform after changes constitutes acceptance of the updated Terms. Material changes will be communicated via the Platform.
