About this skill
This skill identifies unused functions and dead code in a codebase using static analysis. It helps developers locate code that is never called or unreachable, which can be removed to reduce maintenance burden and potential confusion. An agent or developer should use it when cleaning up a codebase, refactoring legacy code, or verifying that recently removed features have no remaining references.

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 typescriptOutput 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 pointstest_*,*_test- Test functionssetup,teardown- Fixtures@app.route,@api.endpoint- Framework handlers
# Custom entry points
tldr dead src/ --entry main api_handler background_jobIntegration
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 |
