Dead Code

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.
