Serena – Semantic Code Understanding
IDE-like semantic code operations via CLI. Provides symbol-level code navigation, editing, and project memory.
Execution Methods
# Prerequisites: pip install serena-agent typer
# Environment: SERENA_PROJECT (default: current directory)
# Symbol operations
python -m skills.serena.tools symbol find MyClass --body
python -m skills.serena.tools symbol overview src/main.py
python -m skills.serena.tools symbol refs MyClass/method
python -m skills.serena.tools symbol rename OldName NewName --path src/file.py
# Memory operations
python -m skills.serena.tools memory list
python -m skills.serena.tools memory read project_overview
python -m skills.serena.tools memory write api_notes --content "..."
# File operations
python -m skills.serena.tools file list --recursive
python -m skills.serena.tools file find "**/*.py"
python -m skills.serena.tools file search "TODO:.*" --path src
# Extended tools
python -m skills.serena.tools cmd run "git status"
python -m skills.serena.tools config read config.json
Tool Routing Policy
Prefer Serena Over Built-in Tools
| Task | Avoid | Use Serena CLI |
|---|---|---|
| Find function | grep "def func" |
symbol find func --body |
| List file structure | cat file.py |
symbol overview file.py |
| Find usages | grep "func(" |
symbol refs func |
| Edit function | Edit tool |
symbol replace func --path file.py |
| Rename | Manual find/replace | symbol rename old new --path file.py |
When to Use Built-in Tools
- Simple text search (non-code patterns)
- Configuration files (JSON, YAML)
- Documentation files (Markdown)

symbol find MyClass --depth 1 # Explore class members
symbol find MyClass/method --body # Get implementation details
Phase 2: Analysis
symbol refs MyClass/method # Impact analysis
memory list # Check project knowledge
memory read architecture # Retrieve context
Phase 3: Modification
symbol find target --body # Verify target
symbol replace target --path f --body "..." # Edit
symbol rename old new --path f # Refactor
Error Handling
{"error": {"code": "ERROR_CODE", "message": "description"}}
| Error Code | Recovery |
|---|---|
INVALID_ARGS |
Check --help |
TOOL_NOT_FOUND |
Use workflow tools |
INIT_FAILED |
Check serena-agent installation |
