/configure:dead-code
Check and configure dead code detection tools.
When to Use This Skill
| Use this skill when... | Use another approach when... |
|---|
| Setting up dead code detection for a new project | Running an existing dead code scan (knip, vulture) |
| Auditing whether Knip, Vulture, or cargo-machete is configured correctly | Manually removing specific unused exports or imports |
| Migrating between dead code detection tools | Debugging why a specific file is flagged as unused |
| Adding dead code checks to CI/CD pipelines | Reviewing dead code findings one by one |
| Standardizing dead code detection across a monorepo | Configuring linting rules (/configure:linting instead) |
Context
- Project root: !
pwd
- Package files: !
find . -maxdepth 1 \( -name 'package.json' -o -name 'pyproject.toml' -o -name 'Cargo.toml' \)
- Knip config: !
find . -maxdepth 1 \( -name 'knip.json' -o -name 'knip.config.*' \)
- Vulture config: !
find . -maxdepth 1 \( -name '.vulture' -o -name 'vulture.ini' \)
- Pre-commit: !
find . -maxdepth 1 -name '.pre-commit-config.yaml'
- Project standards: !

Parameters
Parse from command arguments:
--check-only: Report compliance status without modifications (CI/CD mode)--fix: Apply fixes automatically without prompting--tool <knip|vulture|deadcode|machete>: Override tool detection
Dead code detection tools:
- JavaScript/TypeScript: Knip (finds unused files, exports, dependencies)
- Python: Vulture or deadcode (finds unused code)
- Rust: cargo-machete (finds unused dependencies)
Execution
Execute this dead code detection compliance check:
Step 1: Detect project language and existing tools
Check for language and tool indicators:
