deadcode

Find the code nobody uses. Remove it before it rots.

---

Your codebase has dead code. A lot of it.

Studies show 10-30% of code in a typical project is dead. Unused exports. Orphan files nobody imports. Commented-out blocks from three sprints ago. Console.log statements that survived code review. Functions with pass as the body. CSS classes that match no element.

Dead code is not harmless. It slows onboarding. It confuses grep. It inflates bundles. It creates false positives in security scans. And it grows.

DeadCode finds the rot before it spreads. Pre-commit hooks. Local scanning. 60+ patterns across 5 language categories. Zero data leaves your laptop.

Quick Start

# 1. Install via ClawHub (free)
clawhub install deadcode
# 2. Scan your repo
deadcode scan
# 3. Install pre-commit hooks (Pro)
deadcode hooks install

That's it. Every commit is now scanned for dead code before it lands.

What It Does

Scan source files for dead code

One command to scan any file, directory, or your entire repo. 60+ regex patterns detect dead code across JavaScript/TypeScript, Python, Go, CSS/SCSS, and general code cruft.

Block commits with pre-commit hooks

Install a lefthook pre-commit hook that scans every staged source file. If dead code is detected, the commit is blocked with a clear cleanup message.

Generate dead code reports

Produce markdown reports with severity breakdowns, orphan file detection, and cleanup priority. Ideal for tech debt tracking and sprint planning.

Find orphan files

Detect files that are never imported, required, or referenced by any other file. Excludes entry points, test files, and config files automatically.

Manage ignore rules

Define organization-specific ignore patterns and check IDs. Skip known false positives without disabling entire categories.

SARIF output for CI/CD

Generate SARIF v2.1.0 output compatible with GitHub Code Scanning, Azure DevOps, and other CI systems.
