I use Claude Code, OpenCode, and Codex CLI every day. They're great at writing code, but I have no idea what they're doing while they work. Tokens burn with no visibility, context fills up silently, and when a session ends everything the agent learned is gone.

Sidekick is a VS Code extension and standalone terminal dashboard that sits alongside your AI coding agent and shows you what's happening in real time.

Try it:

  VS Code: search "Sidekick Agent Hub" in the extension marketplace
  CLI:     npm install -g sidekick-agent-hub && sidekick dashboard

It auto-detects which agent you're running.

What it shows you:

- Live token and cost tracking with burn rate - Full tool call timeline — every file read, write, bash command - Session mind maps (force-directed graph in VS Code, tree in terminal) - Destructive command alerts (rm -rf, force push, drop table) - Decision log and knowledge notes that persist across sessions - Session export to markdown, JSON, or text

It also does inline completions, code transforms, and commit messages using your existing Claude subscription or API key — but the monitoring is the part I think is missing from the ecosystem.

Works with Claude Code, OpenCode, and Codex CLI.
