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 🙏

codex-show-next-model-input

Preview the next model-visible request for an existing local Codex session, including its reconstructed conversation history.

Run without arguments to see usage and the ten most recent local session IDs:

npx codex-show-next-model-input
npx codex-show-next-model-input <SESSION_ID> "<PROMPT>" > /tmp/model-input.json

Or open a local visual inspector with three linked overview lenses, a searchable timeline, and a lossless Raw JSON view:

npx codex-show-next-model-input --open <SESSION_ID> "<PROMPT>"

The viewer listens only on 127.0.0.1, uses a random URL, and keeps running until you press Ctrl+C. It does not upload the captured request or load external assets.

The Overview includes an explanation of how the request is assembled, an input-order Request Map, and a byte-weighted Context Atlas. Byte size is not a token estimate.

The tool automatically reads the session's original cwd, creates an ephemeral read-only fork, captures the first inference_started payload, stops Codex, and removes the temporary trace. The original session is not resumed or modified.

Requirements: Node.js 20+, Codex CLI 0.152.0+, and a local saved session.

The capture sends one real model request and may incur usage. Output can contain prompts, source code, tool results, paths, and secrets. Keep it out of Git and do not share it without review.
