OpenContext is an open-source ai agents skill for AI coding assistants such as Claude Code, Codex CLI, and ChatGPT, built by 0xranx. A personal context store for AI agents and assistants—reuse your existing coding agent CLI (Codex/Claude/OpenCode) with built‑in Skills/tools and a desktop GUI to capture, search, and reuse project knowledge across agents and repos. It has 1,263 GitHub stars.
OpenContext failed SkillsLLM's automated security scan, which flagged one or more high-severity issues. Review the Security Report section carefully before using it.
Clone the repository with "git clone https://github.com/0xranx/OpenContext" and add it to your Claude Code skills directory (see the Installation section above).
OpenContext is primarily written in JavaScript. It is open-source under 0xranx on GitHub, so you can review or fork the full source.
Yes. SkillsLLM lists many other AI Agents skills you can browse and compare side by side. Open the AI Agents category from the badge at the top of this page, or use the Related Skills and comparison links further down to weigh OpenContext against similar tools.

When you use an AI assistant to build things, context gets lost (across days, repos, chats). 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.
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 |
oc CLI — manage a global contexts/ library (folders/docs, manifests, search)oc init)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.
npm install -g @aicontextlab/cli
| Path | Best For | Get Started |
|---|---|---|
| 🖥️ Desktop App | Visual users who want a native UI | Download from 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.
# 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)
