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 🙏

@godspeedai/cognate-provider-openai-oauth

Preview — not validated against production. The adapter passes a fake-issuer conformance suite, but no live ChatGPT sign-in has been recorded yet. Treat plan-backed inference as unsupported until that evidence exists.

Sign in with ChatGPT (SIWC) for open-source, locally hosted Cognate runs: an OAuth/OIDC credential adapter and a governed subscription-backed Responses provider.

  • Dynamic client registration (dynamic_agent_client → issued oaiapp_... id) with a stable per-host ext_agent_host_id.
  • PKCE S256, fresh state/nonce per attempt, loopback callback on 127.0.0.1 (only the port varies), system-browser handoff without a shell.
  • ID-token validation against OpenAI's JWKS (RS256/ES256 only), issuer/audience/expiry/nonce checks, sub as the account identity.
  • Atomic, 0600 credential records per issued client id; refresh-token rotation replaces the whole token set under a single-flight lock.
  • Revocation on sign-out; automation use is a separate, secret-free, explicit local consent record enforced by assertSubscriptionUse (see @godspeedai/cognate-provider-auth).
  • Plan-backed inference goes through the Responses adapter with the SIWC preview constraints enforced: store:false, stream:true, no temperature/max_output_tokens/system-role input.

This package never reads credentials from other applications (Codex, OpenCode, …) and never places tokens in URLs, logs, or durable events. A bearer token typed into a field is not an OAuth sign-in; use @godspeedai/cognate-provider-auth sources for that case.
