Skill

The MailKaro Skill is a single markdown file (skills/mailkaro/SKILL.md) that teaches a model the design JSON shape, the block catalog, merge tags, special links, branding, and the render formats, so it authors valid emails first try. It's plain markdown: load it in any model, with or without the MCP server.

Use it anywhere#

  • Claude (Skills), drop the skills/mailkaro folder into your skills directory; the frontmatter registers it.
  • Cursor / Windsurf / VS Code, add SKILL.md to your rules / context (e.g. .cursor/rules) so it's always loaded.
  • Any LLM / chat, paste or attach SKILL.md; it's self-contained reference.
  • With MCP, the same guidance is the mailkaro://guide resource, so an MCP host can read it directly.
The Skill tells the model to confirm a block's fields with get_block_schema (or the mailkaro://blocks resource) rather than guessing, so it always matches the live renderer, even as blocks evolve. No stale copy to maintain.

Everything in these docs, distilled for a model, and it maps 1:1 to the MCP tools, so an AI can go straight from understanding to building.
