OpenLore vs rtfm

OpenLore: OpenLore turns any evolving codebase into a navigable knowledge graph backed by OpenSpec living specifications. It maintains persistent architectural context across AI agent sessions, reducing token consumption for orientation from 15,000-50,000 to about 1,000-3,000 tokens. The three-layer system includes static analysis, spec generation, and an MCP agent runtime with 45 tools.; rtfm: RTFM is a local, open-source retrieval layer that indexes everything in a project (code, docs, PDFs, etc.) so that AI agents can find the right context instantly without hallucinations or cloud costs. It integrates with Claude Code and other MCP clients, supports multiple formats, and provides fast search with progressive disclosure.
