opencode-codex-usage-plugin

Show your Codex usage and reset times directly in the OpenCode sidebar.

This plugin reads Codex usage from Codex App or the Codex CLI and renders the current 5-hour and weekly limits inside OpenCode, so you can keep an eye on quota without leaving the TUI.

Install

[!IMPORTANT] This is a TUI plugin, so configure it in tui.json, not in opencode.json. The plugin field in opencode.json is for server/runtime plugins and will not load this sidebar plugin.

Use OpenCode's native plugin installer:

opencode plugin opencode-codex-usage-plugin@latest --global

This installs the plugin and updates your global OpenCode TUI config automatically.

Alternatively, add the plugin manually to your OpenCode TUI config (~/.config/opencode/tui.json):

// tui.json
{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": ["opencode-codex-usage-plugin"]
}

Restart OpenCode after changing the config.

Requirements

Install either Codex App or the Codex CLI. The plugin looks for Codex in common locations and on your PATH.

If your Codex command lives somewhere else, set OPENCODE_CODEX_USAGE_COMMAND in your shell config:

# ~/.zshrc or ~/.bashrc
export OPENCODE_CODEX_USAGE_COMMAND="/path/to/codex"

Then reload your shell config or open a new terminal before starting OpenCode.

Contributing

Contributions are welcome! Please open an issue or submit a pull request on GitHub. To get started fork the repo, install the dependencies and in your OpenCode TUI config add the local path to the output of the plugin like so:

// tui.json
{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": [
    "file:///Users/<your_username>/path/to/your-clone/opencode-codex-usage-plugin/dist/tui.js"
  ]
}

The plugin logic is made with Effect. There is no particular reason I chose it, it was simply and excuse to try it out.
