Cross Agent Skills

Cross-Platform Skill Authoring

How to structure a skill package so it works across Pi, Claude Code, and OpenClaw with zero duplication.

Before You Start

Check the current repo:

1. Look for .claude-plugin/marketplace.json — lists available plugins
2. Look for .claude-plugin/plugin.json — plugin manifest
3. Look for package.json with pi.skills — Pi/OpenClaw is configured
4. If none exist, this is a new setup

The Universal Artifact

All three platforms read the same file: SKILL.md following the Agent Skills spec.
