Conventions

• SKILL.md is the universal skill manifest (skills.sh ecosystem)
• .claude-plugin/ dirs and plugin.json are Claude Code conventions -- keep both for compatibility
• $CLAUDE_PLUGIN_ROOT env var in hooks references skill root at runtime (Claude Code specific)
• Keep skills self-contained (no cross-skill dependencies)
• Skills should document agent compatibility in their README
