Dead Code Detection
Find unused functions and dead code using TLDR static analysis.
Quick Start
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
Output Format
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)
Cross-Platform
Works on Windows, Mac, and Linux (including WSL).
Windows (PowerShell)
tldr dead .
Mac/Linux
tldr dead .
Entry Points
Functions matching entry patterns are excluded from dead code analysis:
-
main , cli
-
Application entry points
-
test_* , *_test
-
Test functions
-
setup , teardown
-
Fixtures
-
@app.route , @api.endpoint
-
Framework handlers
Custom entry points
tldr dead src/ --entry main api_handler background_job
Integration
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
