skill-dead-code-legacy
Overview
This skill performs a systematic dead code and legacy pattern audit of any codebase. When invoked, it scans source files for unused exports, unreachable code, zombie routes, orphaned tests, deprecated API usage, outdated dependencies, legacy idioms, and accumulated technical debt markers. It produces a three-tier severity report (REMOVE NOW / REVIEW & CLEAN / TECHNICAL DEBT) with safe removal guidance.
Trigger phrases: "dead code audit", "find unused code", "legacy cleanup", "deprecated APIs", "zombie routes", "remove dead code", "technical debt scan", "unused dependencies", "TODO cleanup".

| Project source directory | Yes | The root path or src/ folder to scan |
| Language / framework | Auto-detected | Detected from package.json, file extensions, config files |
| Scope | Optional | Limit scan to dead code only, legacy only, or technical debt only |
If no project path is provided, ask the user to specify the directory or share the relevant files.
