Serena provides language-server-quality code navigation for AI agents.
Use Serena instead of grep when you need:
context/plugins.md for installation status.serena/project.yml@serena find-references UserService
@serena go-to-definition UserService.getById
@serena rename UserService.getById getUserById
Use grep for text-based search:
grep -rn 'UserService\.getById' --color=never . 2>/dev/null | head -20
