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 Usage Plugin for OpenCode

OpenCode plugin that exposes a /codex-usage TUI command and <leader>i shortcut for viewing Codex ChatGPT usage limits and credits. It also keeps a codex_usage tool for manual/debug agent use.

Usage

  1. Install the package globally:

    npm install -g @illiadotdev/codex-usage-plugin

  2. Register the plugin in OpenCode:

    codex-usage-plugin --install

    This builds dist/ and registers the generated plugin path in ~/.config/opencode/opencode.jsonc.

  3. Restart OpenCode.

  4. Run /codex-usage in the OpenCode TUI, or press the leader key then i (ctrl+x then i by default).

The installer asks which usage dialog design to use. The compact v1 design remains the default. To change it later, run:

codex-usage-plugin --settings

For non-interactive use, pass --settings=v1 or --settings=v2.

To remove the plugin registration:

codex-usage-plugin --uninstall

To remove the npm package too:

npm uninstall -g @illiadotdev/codex-usage-plugin

To upgrade the installed package:

codex-usage-plugin --upgrade
codex-usage-plugin --upgrade 0.2.9

This checks the resolved npm version first, then runs npm install -g @illiadotdev/codex-usage-plugin@latest by default, or installs the version you pass. Installation is skipped when that version is already installed.

What It Reads

The plugin reads auth from:

  • OPENCODE_AUTH_PATH, when set
  • ~/.local/share/opencode/auth.json
  • ~/Library/Application Support/opencode/auth.json on macOS
  • ~/.opencode/auth.json
  • %LOCALAPPDATA%\\OpenCode\\auth.json as a fallback
  • $CODEX_HOME/auth.json, when CODEX_HOME is set
  • ~/.codex/auth.json, otherwise

It calls the same ChatGPT backend usage surfaces Codex uses:

  • https://chatgpt.com/backend-api/wham/usage
  • https://chatgpt.com/backend-api/wham/profiles/me

Limitations

Plugin supports file-backed OpenCode/Codex auth only. If your client stores tokens in the OS keyring, the plugin will report that auth.json is unavailable. Keyring support can be added later.

The plugin never prints access tokens, refresh tokens, or ID tokens.
