Local file watcher
The Watcher — Your Silent Code Guardian
Runs in your terminal. Watches every save. Auto-fixes dangerous patterns. Surfaces structural, semantic, and dependency risks for your review.
Three steps. Zero friction.
Start
Run `trvw` in any project folder
Code
Write normally. The Watcher detects every save with 1-second debouncing
Review
Pattern Analysis auto-fixes safe issues. Structural, Semantic, and Dependency findings surface for your review.
Up to four lanes. One watcher.
Pattern Analysis
Auto-fixes dangerous syntax patterns (eval, pickle, yaml.load, etc.).
Structural Analysis
Catches architecture-level issues (missing auth, insecure configs).
Semantic Analysis
Finds logic flaws AI-generated code often misses.
Dependency Analysis
Flags vulnerable packages in your requirements.
Before AI cleanup. After TRVChek.
