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 🙏

Readme

@tokentop/agent-copilot-cli

npm CI License: MIT

tokentop agent plugin for GitHub Copilot CLI (GitHub's terminal coding agent). Parses session data, tracks token usage, and provides real-time activity monitoring.

Capabilities

| Capability | Status | |-----------|--------| | Session parsing | Yes | | Credential reading | No | | Real-time tracking | Yes | | Multi-provider | No |

How It Works

This plugin reads GitHub Copilot CLI's local session files from ~/.copilot/session-state/ to extract:

  • Session metadata (start time, project path, summary)
  • Token usage per message (estimated from content length; real data when available)
  • Model information per conversation turn via session.model_change timeline
  • Real-time file watching for live session updates

Token Data Limitations

Copilot CLI currently marks all token-bearing events (assistant.usage, session.shutdown) as ephemeral, meaning they are tracked in-memory for the /usage command but never written to events.jsonl. As a result, token counts are estimated from response content length (~4 chars/token). The plugin is structured to automatically use real token data (including cache read/write breakdown) when Copilot CLI begins persisting assistant.usage events. See copilot-cli#1152.

Model Tracking

The plugin builds a timeline from session.model_change events and resolves the correct model for each message based on its timestamp. If a user switches models mid-session, each model appears as a separate entry — matching the behavior of the Claude Code and OpenCode plugins.

Install

This plugin is bundled with tokentop — no separate install needed. If you need it standalone:

bun add @tokentop/agent-copilot-cli

Requirements

  • GitHub Copilot CLI installed (~/.copilot directory must exist)
  • Bun >= 1.0.0
  • @tokentop/plugin-sdk ^1.3.0 (peer dependency)

Permissions

| Type | Access | Paths | |------|--------|-------| | Filesystem | Read | ~/.copilot |

Development

bun install
bun run build
bun test
bun run typecheck

Contributing

See the Contributing Guide. Issues for this plugin should be filed on the main tokentop repo.
