AgentOS - Universal Agent Runtime
AgentOS is an open-source universal agent runtime designed for the multi-agent era. It provides a unified execution environment where AI agents can discover, install, and compose skills from a decentralized marketplace, while connecting to any MCP-compatible tool server.
pip install nexus-agentos
Why AgentOS?
| Problem | AgentOS Solution |
|---|---|
| Agents siloed in different frameworks | Universal runtime — one env runs OpenClaw, LangChain, custom agents |
| No marketplace for agent skills | Built-in Skill Market — devs upload, users install, admins review |
| MCP servers fragmented | 8 built-in MCP servers, 34 tools out of the box |
| No TUI for agent management | Terminal UI (Textual) — file browser, skill manager, task runner |
| Hard to compose multi-agent workflows | Sub-agent dispatch — agents delegate to specialists automatically |
Quick Start
1. Install
pip install nexus-agentos
# Or from source
git clone https://github.com/wuyifeishu/nexus-agentos.git
cd nexus-agentos && pip install -e .
2. Launch the Skill Marketplace
python -m agentos.server.marketplace_platform
Open http://localhost:8899/static/platform.html — you'll see the full marketplace with:
- Browse: search/discover 64 built-in skills across 11 categories
- Login/Register: JWT auth for developers
- Upload: zip your skill with a
skill.yamlmanifest - Review: admin panel for security scanning, approve/reject
3. Run the Terminal UI
python -m agentos.desktop
Ctrl+M opens the Market Panel. Ctrl+F opens File Browser. Full keyboard-driven.

Skill Marketplace Platform
A production-ready marketplace for the AgentOS ecosystem:
For Developers
- Register/login with email & password (bcrypt + JWT)
- Upload
.zipskill packages withskill.yaml/manifest.json - Automatic security scanning on upload: dangerous imports, shell injection, obfuscation, hardcoded keys, excessive permissions
- Track downloads and reviews
- Developer profile pages
For Users
- Browse/search skills by name, category, tags
- One-click install from any ecosystem source
- Rate and review installed skills
For Admins
- Review queue with security findings per skill
- Approve/reject with comments
- Skill quality and safety enforcement
API Endpoints
POST /api/auth/register - Create developer account
POST /api/auth/login - Login, receive JWT
GET /api/skills - Browse/search published skills
GET /api/skills/{id} - Skill detail
GET /api/skills/{id}/download - Download skill zip
POST /api/skills/upload - Upload new skill (auth required)
GET /api/my/skills - My uploaded skills
GET /api/developers/{username} - Developer profile
POST /api/admin/review/{id} - Approve/reject (admin)
GET /api/admin/review-queue - Pending reviews (admin)
GET /api/categories - Category listing
Security Scanning
Every uploaded skill is automatically scanned for:
| Check | Severity | Description |
|---|---|---|
| Dangerous imports | Critical | os.system, subprocess, socket, ctypes |
| Shell injection | Critical | os.system(), eval(), exec(), __import__() |
| Code obfuscation | High | Base64-encoded payloads, eval chains |
| Hardcoded secrets | High | API keys, tokens, passwords in source |
| File permission escalation | Medium | chmod 777, os.chown |
| Network exfiltration | High | Suspicious requests.post to unknown hosts |
