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).

```bash
# 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
