Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Overwatch

npm version license node

Overwatch is a lightweight, IDE-agnostic security daemon for AI coding assistants. It attaches to your IDE's native hook system and evaluates every prompt, tool call, file operation, shell command, and MCP interaction in real time, forwarding events to the Highflame Cerberus service for threat detection and policy enforcement.

It runs on the developer's machine, alongside the IDE rather than in the network path. There are no proxies, no certificates, and no added latency. Activity flows into Highflame Studio for organization-wide discovery, threat monitoring, and audit.

Works with Cursor, Claude Code, GitHub Copilot, Gemini CLI, OpenAI Codex, and more.

Installation

npm install -g @highflame/overwatch

The matching native scanner binary is installed automatically for your platform via optional dependencies (macOS, Linux, and Windows on both x64 and ARM64).

Quick Start

# Start the daemon (opens a browser to authenticate with Highflame Studio on first run)
overwatch start

# Confirm it's running and see which IDEs it attached to
overwatch status

# (Optional) Auto-start on boot
overwatch install-service

On first run, Overwatch authenticates with Highflame Studio, detects every supported coding assistant on your machine, and attaches hooks to each one. You don't need to restart your IDE or reconfigure your assistant.

For the full step-by-step setup, alternative install paths (script, Windows native, Claude Code plugin, Copilot, Tailscale), and policy configuration, follow the Installation Guide.

Common Commands

| Command | What it does | | --- | --- | | overwatch start | Start the daemon; authenticate and install hooks for any detected IDE | | overwatch stop | Stop the daemon | | overwatch restart | Restart (useful after an upgrade) | | overwatch status | Show daemon health, event count, auth status, and installed hooks | | overwatch install <ide> | Install hooks for a specific IDE (cursor, claudecode, github_copilot, gemini_cli, openai_codex) | | overwatch scan | Scan the MCP servers configured in your IDEs for security issues | | overwatch whoami | Show the authenticated user, organization, and session expiry |

Run overwatch --help for the full list.

Requirements

  • Node.js 18 or newer
  • A supported coding assistant (Cursor, Claude Code, GitHub Copilot, Gemini CLI, or OpenAI Codex)
