Cursor Knowledge Fabric — .cursorrules + codebase indexing overview

Cursor's knowledge fabric combines project-level rule files (.cursorrules, .cursor/rules/) with whole-codebase semantic indexing. The .cursorrules file and the rules directory provide persistent project-specific instructions akin to CLAUDE.md. Cursor also indexes the entire codebase into a vector store for semantic code search, enabling RAG-style retrieval of relevant code snippets and documentation during conversations. Context pinning (@-mentions) lets users manually anchor specific files, docs, or web pages as knowledge sources.

notes

Cursor's knowledge retrieval is hybrid: .cursorrules files are loaded via file-hierarchy traversal (like CLAUDE.md), while codebase context is retrieved via vector-embedded semantic search over the indexed project. Cursor does not have auto-memory extraction — knowledge must be manually authored in .cursorrules or .cursor/rules/ files. AGENTS.md support was added in >=0.40.0 for cross-agent compatibility.
