carbon-panel — Claude Code skill: what it does, how to install
Opens a pane with a CO₂ molecule and session warming stripes. Ask for it when you want to view those figures in the interface.
npx skills add gwittebolle/claude-carbon --skill carbon-panel -a claude-codeWhat carbon-panel does
carbon-panel works with the claude-carbon mod, which opens a pane showing a CO₂ molecule and warming stripes for sessions. In Claude Code, the pane appears in the terminal; in the Claude desktop app, it appears in the Code tab. The /carbon-report command returns the same figures as text.
When the mod does not run, the skill responds with text instead of opening the pane. That applies to the VS Code extension chat, cloud sessions, and Claude Code versions older than 2.1.287; the desktop app threshold is 2.1.286. In those cases, expect a text report rather than the pane.
What it helps with
- open a pane with a CO₂ molecule
- view warming stripes for sessions
- get the pane’s figures as text
Example prompts for the agent
- Open the carbon pane with the CO₂ molecule and session stripes.
- Show me the same figures as text with
/carbon-report.

Source text
SKILL.md · MIT
--- name: carbon-panel description: Open the carbon pane, your CO2 molecule and the warming stripes of your sessions disable-model-invocation: true --- The claude-carbon mod handles this command itself and opens its pane, so this text only reaches you where the mod does not run: the VS Code extension's chat panel, a cloud session, or a Claude Code older than 2.1.287 (2.1.286 in the desktop app). Reply in the user's language, in two short sentences and nothing else: the carbon pane opens in the terminal or in the Code tab of the Claude desktop app, from Claude Code 2.1.287; here, `/carbon-report` gives the same figures as text. Do not run any tool.
