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

@claudecam/hook

Ultra-lightweight hook binary for Claude Agent Monitor (CAM) -- Mission Control for Claude Code agents.

npm version License: MIT

What This Package Does

Captures Claude Code hook events and sends them to the CAM server. Designed to be as fast and invisible as possible.

Key properties:

  • Zero external dependencies -- uses only native Node.js http module
  • < 10ms latency -- never blocks Claude Code
  • Fails silently -- if the CAM server is down, nothing breaks
  • WSL auto-detection -- automatically resolves Windows host IP when running in WSL
  • Retry with fallback -- tries configured host, then localhost, then 127.0.0.1

Hook Events Captured

| Hook | When it fires | |------|--------------| | SessionStart | Claude Code session begins | | SessionEnd | Session ends | | PreToolUse | Before every tool call | | PostToolUse | After tool call completes | | PostToolUseFailure | When a tool call fails | | UserPromptSubmit | User sends a prompt | | Notification | Claude Code notification | | Stop | Main agent stops | | SubagentStart | Teammate agent starts | | SubagentStop | Teammate agent stops |

Usage

This package is configured automatically by @claudecam/cli. You typically don't install it directly.

# Recommended: let the CLI handle everything
npx @claudecam/cli start

Debug Mode

export CAM_DEBUG=1
# Hook will log connection attempts and payloads to stderr
