Serena Skill

Serena provides language-server-quality code navigation for AI agents.

When to Use Serena

Use Serena instead of grep when you need:

• Go-to-definition — find where a symbol is defined (not just where its name appears)
• Find-all-references — semantic references, not text matches
• Rename-symbol — safe rename across all callers
• Call hierarchy — who calls this function?

Requirements

• Serena must be configured: check context/plugins.md for installation status
• Serena project config: .serena/project.yml

Operations

Find all references to a symbol

@serena find-references UserService

Go to definition

@serena go-to-definition UserService.getById

Rename symbol

@serena rename UserService.getById getUserById

Fallback (if Serena is not available)

Use grep for text-based search:

grep -rn 'UserService\.getById' --color=never . 2>/dev/null | head -20
