TRVChek — The Invisible Dev Companion

A local CLI tool that watches every file you save, auto-fixes dangerous syntax patterns, and surfaces deeper risks before they reach production. Runs entirely on your machine.

Get TRVChek See How It Works

Deterministic scanning and fixes run locally. Licence activation and renewal checks need the internet.

Local watcher mode

$curl -sSL https://install.trvchek.com | bash

$trvchek activate <your-key>

$trvw --auto-fix

▹ Watching 1,247 files
▹ Last save checked in 12ms

Commands are real; watcher stats are illustrative.

▹Deterministic scanning and fixes stay on your machine

▹No telemetry. No analytics. No data collection.

▹Only licence checks, and cloud-assisted lanes you switch on, use the network

How it works

Three steps. No setup theater.

Run the watcher

$ trvw

Start TRVChek in your project folder. It checks the source and config files it supports on every save, locally.

Code normally

$ code .

Keep using Cursor, GitHub Copilot, Windsurf, or any editor. TRVChek checks each save in real time.

Catch and fix

$ trvw --auto-fix

Issues are flagged instantly. Enable auto-fix and TRVChek patches the bugs AI wrote before you commit.

What's inside

Built for the bugs AI writes.

56 AI-specific bug detectors

Auth bypass, SQL injection, hallucinated imports, silent exceptions, unsafe deserialization and more — the failure modes AI assistants actually produce.

File watcher mode

Run `trvw` and TRVChek checks every save automatically. No manual scans, no CI waits.

Auto-fix on save

Enable `--auto-fix` and TRVChek patches safe issues as you type, leaving a local backup before every change.

Context-aware severity

A bare except in a test file isn't the same risk as one in your auth layer. TRVChek weights findings by file role.

Local execution by default

Deterministic checks and fixes run in your shell with no uploads and no telemetry. Licence activation and renewal checks use the network, as do cloud-assisted lanes you switch on.

Why local?

Your code is yours.

✓Deterministic checks and fixes never upload your code
✓Only licence checks and opt-in cloud-assisted lanes use the network
✓Auto-fixes dangerous patterns as you save, before you commit
