Project vs Global Mode

Project mode (default when in a git repo):

• Skills install to .agents/skills/
• Metadata stored in skills.lock

Global mode (when not in a git repo, or with --global):

• Skills install to ~/.agents/skills/
• Available across all projects

What is skills.lock?

skills.lock records where each skill came from:

• Source repository URL
• Commit hash
• Skill metadata (description, license, compatibility)

This enables trv update to fetch newer versions from the original sources.
