0xranx/OpenContext
OpenContext is a personal knowledge and context store built for AI coding assistants such as Cursor, Claude Code, Codex and OpenCode. It addresses the problem that context is lost across days, repositories and chat sessions, forcing the user to re-explain background and decisions while the assistant proceeds on stale assumptions. Instead of shipping its own agent, OpenContext reuses whichever coding agent CLI the user already has and layers a graphical interface plus built-in skills and tools on top, so the workflow becomes load history first, act, then persist what was learned. The project ships several pieces. The oc command-line tool manages a global contexts library of folders, documents and manifests with search. An MCP server exposes the same store as tools so Cursor, Claude Code, Codex and other agents can call it directly. Running oc init generates user-level skills for Cursor, Claude Code and Codex plus slash commands for Cursor and Claude Code, giving commands to load background before working, search for relevant documents, create a new document and persist what was learned at the end of a session; installation targets and non-interactive flags for selecting tools are documented. A desktop application built with Tauri offers a native interface for managing, searching and editing contexts, and a local web UI covers browsing and editing without installing anything. The CLI is distributed on npm as @aicontextlab/cli and desktop builds are published as GitHub releases. Documentation is available in English and Chinese. The intended users are developers who work daily with agentic coding CLIs and want a shared, agent-readable knowledge layer that spans projects, so that decisions and background written once can be read and updated by any of their agents.
