# Carbon Builder IBM's own Carbon Design System skill, composed over a vendored upstream body and the hosted Carbon MCP server. ## How to use this skill 1. **Start at `base/SKILL.md`** — it is the full protocol: query planning, the capability matrix, mandatory context-gathering and code-audit rules, and the result-shape tables. Load `base/references/<topic>.md` only for the areas the task touches. 2. **The base assumes five MCP tools** (`code_search`, `docs_search`, `get_charts`, `labs_search`, `code_audit`) from the `carbon-design` server this plugin registers. Discover the available tool names by capability; client prefixes differ. In Codex, use its tool discovery surface instead of assuming Claude tool names. The hosted server requires an **approved account**: if a call fails authentication, use the client connection UI (Claude Code: `/mcp`; Codex: the plugin connection controls, or `codex mcp login <registered-server-name>` for a CLI-registered server). Authenticate in the browser, and if no approved account exists, say so instead of guessing — approval is requested at <https://mcp.carbondesignsystem.com>. 3. **No MCP access** (no approved account, access lost, or server down)? The base's protocol still applies — substitute each tool with its public-docs equivalent and say plainly that answers came from public docs, not the MCP index: | Base calls | Substitute | |---|---| | `code_search` (components, variants, props) | F
