Open-source skill instructions · MIT
Start with one testing area.
25 standalone skills use your coding agent’s existing tools. No CARBON harness installation, MCP connection or separate API key is required. Your agent’s normal usage costs apply.
Download a selected skill and use your host’s skill installer. Direct Claude Code skills use short names such as /security; plugin installations may add a namespace. Check for existing same-named skills before installing.
Each skill provides focused checks, evidence-backed findings and related-area suggestions. These skill files are MIT-licensed; the proprietary CARBON runtime is not included or relicensed. Public GitHub publishing is pending repository selection.
