Drops the SKILL.md into .claude/skills/dead-code.md. Works with Claude Code, Cursor, and any agent that loads SKILL.md files from .claude/skills/.

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
