For agents

cssints ships two agent skills in its package, skills/cssints (writing styles: setup, cn/cx/cv, conditions, tokens and themes, the plugin packages, build errors) and skills/cssints-plugin (writing a plugin on scope(), with its tests). Install them into your agent's skills folder:

npx skills-npm                                # links the skills of every installed package that ships some
npx skills add ./node_modules/cssints/skills  # or the skills CLI, for opencode, Claude Code, Codex, Cursor, ...

Until 0.1 is on npm, point npx skills add at packages/cssints/skills of this repository. Agents working on this repository get .agents/skills/cssints-contributor (also .claude/skills) with no install.

@cssints/mcp is an MCP server with the build's own checks (check_declaration, check_support, check_contrast, compile, search_docs, list_plugins), in packages/mcp with the config for opencode, Claude Code and Cursor. The skills use it when it is configured and work without it.
