cctop

When to choose it

Inspecting session metrics in a terminal pane.

Choose it if: You want detailed local metrics and accept the companion binary requirements.

Look elsewhere if: You need a pure UI snippet with no local process or transcript access.

What the source describes

• The /cctop-pane command toggles an in-process dashboard
• Engine events provide basic context, cost and limit data
• A separately installed cctop binary supplies richer local metrics

Requirements

• Claude Code 2.1.287+; plugin 0.10.0 reports a 2.1.284 tested contract
• Install the companion binary for the full dashboard
• Fullscreen terminal and sufficient columns for a docked pane

Install from the reviewed source

These are the source’s documented installation steps. Read the source, license and requirements first. Marketplace installation can use a different scope from a local --plugin-dir session. Restart Claude Code or use /reload-plugins afterward.

brew install tomstagl/tap/cctop
claude plugin marketplace add tomstagl/cctop
claude plugin install cctop@cctop

Use it after installation

Restart or /reload-plugins, then /cctop-pane. The bundled /cctop skill is a fallback.

Limitations & considerations

• Hybrid package includes a hooks-module Mod, skills and a companion executable
• The companion reads local session/transcript and process data; plugin launches cctop and writes ~/.cctop markers
• Coach can fill the prompt but upstream says it does not submit
• Costs and other metrics include estimates; they are not a subscription bill
• Current 2.1.289 compatibility was not runtime-tested by ClaudeStack

Mods execute with your user privileges and are not sandboxed. They can access files, launch processes and make network requests. ClaudeStack has not run or security-audited this Mod. Use claude plugin validate on a downloaded directory to inspect declared behavior; validation does not certify safety. Check the official trust guidance before loading it.

Source & review record

Our description is based on public documentation and manifests available on 2026-10-05, including the hooks-module pointer and registration source. Installation formats were checked against Claude Code’s documentation. No extension code was executed: this is a source review, not a runtime compatibility test or security audit.

• Original source and documentation
• Reviewed registration source
• License of the reviewed source
• Official plugin installation documentation
