CARBON

Native plugin

CARBON for Codex.

Open the marketplace listingManual package
  1. Open CARBON’s listing and verify the testers.ai publisher. Marketplace review may make the serving version older than the manual package.
  2. Install in a supported local Codex environment, review permissions and start a fresh session.
  3. Choose CARBON in the skill picker, or ask Jay to test your current change. Exact slash-command prefixes depend on the host.

This public-directory build uses explicit commands, not automatic background hooks. It opens protected HTML reports in browser tabs. Ordinary ChatGPT web chat is not the local Codex runtime.

Get your first useful result.

Ask Jay to test my current change with CARBON. Start with a five-minute risk-based pass, show a live rendered report, verify the most important suspected issue, and propose a regression test. Ask before editing code. Finish with evidence and coverage gaps.

Or try the disposable demo. Ask Jay to open CARBON settings to adjust budgets and analytics. Settings do not start a test. Use the returned protected localhost URL in a browser tab, not an HTML source editor.

The report is private. Never share its token-bearing localhost URL. Review and redact exported evidence before sharing.
