Find unused functions and dead code using TLDR static analysis.
# Scan entire project
tldr dead .
# Scan specific directory
tldr dead src/
# Specify entry points (functions to exclude from analysis)
tldr dead . --entry main cli test_
# Specify language
tldr dead . --lang python
tldr dead . --lang typescript
Dead code analysis:
Total functions: 150
Dead functions: 12
Unused functions:
- old_helper (src/utils.py:42)
- deprecated_func (src/legacy.py:15)
- _unused_method (src/api.py:230)
Works on Windows, Mac, and Linux (including WSL).
# Windows (PowerShell)
tldr dead .
# Mac/Linux
tldr dead .
Functions matching entry patterns are excluded from dead code analysis:
main, cli - Application entry pointstest_*, *_test - Test functionssetup, teardown - Fixtures@app.route, @api.endpoint - Framework handlers# Custom entry points
tldr dead src/ --entry main api_handler background_job
This skill replaces the session-start-dead-code hook with on-demand analysis.
| Approach | Pros | Cons |
|---|---|---|
| Hook (removed) | Automatic | Slowed startup by 3s |
| Skill (this) | On-demand, fast | Manual invocation |
# Impact analysis (who calls this?)
tldr impact func_name .
# Architecture layers
tldr arch src/
# Full codebase structure
tldr structure . --lang python
