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 🙏

Verified, attested standard parts for AI coding agents — the CLI

Readme

ctrlai

Verified, attested standard parts for AI coding agents — the agent writes only the seams.

Ctrl AI packages each product capability (transactional email, webhook ingestion, auth, billing, …) as a part: vendored code with a machine-readable contract, a conformance test suite every adapter must pass, and a continuously re-issued signed attestation. Parts are copied into your repo shadcn-style — you own every line, you can read every line, and a boundary guard makes sure nobody (human or agent) edits part interiors and silently voids the attestation.

Status: pre-v0

The hosted registry (registry.ctrlai.com) is live and serves the catalogue, so ctrlai add works out of the box. Attestations are dev-tier (unsigned; real signing is on the roadmap). Watch ctrlai.com for the public launch.

Commands

| Command | What it does | |---|---| | ctrlai init | Install the boundary guard (pre-commit + CI), parts.lock, and AGENTS.md rules | | ctrlai add <targets...> | Vendor parts, a pack, or part[@version][:adapter] specs — resolves order, pulls requires, skips installed. e.g. ctrlai add saas or ctrlai add email.transactional:postmark storage.upload | | ctrlai plan <capabilities...> | Resolve capabilities into a deterministic install plan (no changes made) | | ctrlai audit | Did the repo respect its contracts? Boundary + attestations + routes/env/sprawl in one pass | | ctrlai upgrade <part> | Upgrade a part's version and/or flip its adapter — you get only the seam changes | | ctrlai verify | Verify attestation integrity (hard fail) and freshness (warn; --strict to fail) | | ctrlai guard | Fail if parts/** no longer matches parts.lock | | ctrlai migrate | Apply pending part-owned database migrations |

A pack is a curated capability kit for a product shape — ctrlai add saas installs the whole Team-SaaS skeleton (auth, billing, email, webhooks, jobs, storage, rate limiting, audit, admin) in one command, resolving order and picking sensible default adapters.

The idea in one paragraph

Agents regenerate the same infrastructure on every project, slightly differently every time, unverified and unmaintained. Ctrl AI gives agents a catalog of standard parts they can trust and never regenerate: contracts erase the differences between vendors, conformance suites make adapter claims true, attestations expire so "verified" always means recently. The agent's job shrinks to the seams — the part of your product that should be different.
