Authoritative agent-runtime contract for working inside an OpenKnowledge project — a markdown-CRDT knowledge base exposed over MCP. Use whenever reading, listing, searching, editing, or linting any .md or .mdx file in the project, and before any mcpopen-knowledge tool call (exec, search, write, edit, lint, and the rest). Installed by ok init, so its presence means this is an OpenKnowledge project and it governs every markdown file here.
