You end up re-explaining background, repeating decisions, and sometimes the assistant continues with the wrong assumptions. Most tools stop at storage and don't plug into the coding agent you already use. ## The Solution OpenContext is a lightweight **personal context / knowledge store** for AI assistants (Agents) and coding tools like Cursor / Claude Code / Codex. It reuses your existing coding agent CLI (Codex/Claude/OpenCode) while adding a GUI plus built-in Skills/tools, so your agent can "load history first, then act; ship, then persist". **Skills-first support:** `oc init` generates user-level skills (Cursor/Claude Code/Codex) plus slash commands (Cursor/Claude Code), so agents can load, search, create, and iterate your context with one command. | Before OpenContext | After OpenContext | |-------------------|-------------------| | 📂 Hard to share context across repos/sessions | ✅ Global context library works across all projects | | 🤷 Your ideas can't be quickly perceived by Agent | ✅ Agent loads your background & decisions automatically | | 🔒 Existing knowledge can't be operated by Coding Agent | ✅ Agent can directly read/write your knowledge base | ## What's Included - **`oc` CLI** — manage a global `contexts/` library (folders/docs, manifests, search) - **MCP Server** — so Cursor/Claude Code/Codex/Agents can call OpenContext as tools - **Skills + Slash Commands** — user-level skills for Cursor/Claude Code/Codex and slash commands for Cursor/Claude Code (generated by `oc init`) - **Agent-ready Knowledge Layer** — reuse your existing coding agent CLI (Codex/Claude/OpenCode) with built-in skills/tools and GUI - **Desktop App** — manage/search/edit contexts with a native UI - **Web UI** — browse/edit contexts locally (no install required) ## Why OpenContext for Builders OpenContext's knowledge management Agent can **be the coding agent you already use** (Codex/Claude/OpenCode). You don't pay for a separate agent — you bring your own CLI and get a ready-to-use experience: a GUI for context management plus built-in Skills and tools that let the agent read, search, create, and iterate on your knowledge. ## Quick Start ### Install CLI ```bash npm install -g @aicontextlab/cli ``` ### Choose Your Path | Path | Best For | Get Started | |------|----------|-------------| | 🖥️ **Desktop App** | Visual users who want a native UI | [Download from Releases](https://github.com/0xranx/OpenContext/releases) | | ⌨️ **CLI + Tools** | Developers using Cursor/Claude Code/Codex/AI agents | `npm install -g @aicontextlab/cli && oc init` | | 🔧 **CLI Only** | Power users, automation | `npm install -g @aicontextlab/cli` | OpenContext works with the coding agent CLI you already have — it adds a GUI plus built-in Skills/tools instead of replacing your agent. ### 30-Second Setup (CLI + Cursor/Claude Code/Codex) ```bash # 1. Install npm install -g @aicontextlab/cli # 2. Initialize (prompts for tool setup; defaults to all) cd your-project oc init # 3. Use slash commands (Cursor + Claude Code) # /opencontext-context — load background before working # /opencontext-search — find relevant docs # /opencontext-create — create a new doc # /opencontext-iterate — persist what you learned # Tip: non-interactive installs can use --tools cursor,claude,codex or --no-claude/--no-cursor/--no-codex # # Installed by oc init: # - Cursor: ~/.cursor/commands # - Claude Code: ~/.claude/commands (or $CLAUDE_CONFIG_DIR/commands) # Skills (wrapped from slash commands): # - Cursor: ~/.cursor/skills/opencontext-*/SKILL.md # - Claude Code: ~/.claude/skills/opencontext-*/SKILL.md (or $CLAUDE_CONFIG_DIR/skills) # - Codex: ~/.codex/skills/opencontext-*/SKILL.md (or $CODEX_HOME/skills) # # 4. MCP config is user-level (Cursor/Claude Code/Codex) # - Cursor: ~/.cursor/mcp.json # - Claude Code: ~/.claude/mcp.json (or $CLAUDE_CONFIG_DIR/mcp.json) # - Codex: ~/.codex/mcp.json (or $CODEX_HOME/mcp.json) ``` > 📖 **For detailed usage guide, search configuration, and FAQ, visit the [Website](https://0xranx.github.io/OpenContext/en/usage/).** --- ## CLI Commands (Quick Reference) Run `oc <cmd> --help` for details. | Command | What it does | |---------|--------------| | `oc init` | Initialize OpenContext + user-level tool integrations | | `oc folder ls` | List folders | | `oc folder create <path> -d "desc"` | Create a folder | | `oc doc create <folder> <name>.md -d "desc"` | Create a document | | `oc doc ls <folder>` | List documents | | `oc context manifest <folder>` | Generate file list for AI to read | | `oc search "query"` | Search documents | | `oc mcp` | Start MCP server for MCP clients | | `oc ui` | Start local Web UI | > 📖 **Full command reference available on the [Website](https://0xranx.github.io/OpenContext/en/usage/).** --- ## Development ```bash # Clone & install git clone https://github.com/0xranx/OpenContext.git cd OpenContext && npm install # Desktop app npm run tauri:dev # development npm run tauri:build # production build # Web UI npm run ui:dev # development npm run ui:build # production build ``` --- ## License MIT © [OpenContext](https://github.com/0xranx/OpenContext)
