Project files

Put a project's Stacks board in the files coding agents read: AGENTS.md, CLAUDE.md and a Cursor rule. You get the direction, your avoid rules, design tokens, and the references, prompts and skills on the board, each with its citation.

Ask your agent to call get_context_pack on the connector and write the files it returns.
