What ContextOS does

Context engineering and retrieval for AI coding agents. ContextOS indexes code repositories and their documentation, traces how files and symbols depend on each other, and assembles the smallest, cited, trustworthy context package a coding agent needs for a specific task. Agents consume it through an MCP server; people inspect and tune it in a web studio.
