Field Guide 04: a component documentation template with rules first, a frontmatter schema and 25 checkable writing rules. The kit adds a linter, a generator that writes the API table from the component contract and fails CI on drift, a script that extracts every example for the compiler, an llms.txt and ready-made AGENTS.md, Claude Code, Copilot and Cursor instruction files.
When agents generate UI from your docs and get props, variants or accessibility wrong, or when you are adding llms.txt or an MCP server and need pages worth serving.
