Use GPS (Go Project Structure) for token-efficient project structure analysis.
Activates when users ask about: project structure, codebase organization,
file hierarchies, directory layouts, entry points, project layout,
file navigation, codebase overview, map project structure, project summary,
key files, project architecture, folder structure, or when they need to
understand a codebase quickly. GPS provides 50-70% token reduction vs JSON.
