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

create-agent-harness

Scaffold your own focused AI agent harness — like ruflo, uniquely yours.

Quick start

npx create-agent-harness my-bot

You'll be prompted for template, host, description. Out comes a complete npm package ready to npm publish.

Non-interactive

npx create-agent-harness my-legal-bot \
  --template vertical:legal \
  --host claude-code \
  --description "Contract redline + risk rating"

Templates

| Template | Best for | |---|---| | minimal | Custom starter — kernel only | | vertical:devops | Incident response, on-call workflows | | vertical:support | Customer support, KB-RAG, escalation | | vertical:trading | Quant trading (paper-default, circuit breakers) | | vertical:legal | Contract review with citation checking | | vertical:research | Multi-source dossier with evidence grading |

Hosts

--host selects which host adapter ships with your harness:

| Host | What you get | |---|---| | claude-code | .claude/settings.json with MCP + hooks | | codex | ~/.codex/config.toml with [mcp_servers.*] | | pi-dev | Pi extension (TypeScript, no MCP by design) | | hermes | cli-config.yaml + optional-mcps/*.yaml | | openclaw | ~/.openclaw/openclaw.json + workspace SKILL.md + install runbook | | rvm | RVM partition manifest + capability table + wasm-guest + install runbook (hardware-isolated) |

Multi-host: pass --host multiple times.

Also ships the harness CLI

harness sign      # produce/update the witness manifest
harness verify    # check signature
harness doctor    # smoke-check a scaffolded harness
harness help

Eject from ruflo

If you've been using ruflo and want your own focused harness from it:

npx create-agent-harness --from-existing ./

Lifts agents/skills/commands, rewrites every ruflo / claude-flow reference, preserves attribution blocks marked with <!-- ruflo-attribution-block -->.
