It provides local memory, Deep Sleep, Evolution support-ticket mode, skills, watchdog, followups, and MCP tools through the existing compatibility package.\n\n## Setup\n\nIf your OpenClaw client shows an install action for this skill, use that first. It installs the compatibility package used by the NEXO Desktop runtime via your configured Node package manager.\n\nIf you are setting it up manually, install the runtime core:\n\n```bash\nnpx nexo-brain\n```\n\nAfter the runtime is installed, add the MCP server to your OpenClaw config (`~/.openclaw/openclaw.json`):\n\n```json\n{\n  \"mcp\": {\n    \"servers\": {\n      \"nexo-brain\": {\n        \"command\": \"python3\",\n        \"args\": [\"~/.nexo/server.py\"],\n        \"env\": {\n          \"NEXO_HOME\": \"~/.nexo\"\n        }\n      }\n    }\n  }\n}\n```\n\nRestart the gateway: `openclaw gateway restart`\n\n## What You Get\n\nKey runtime capabilities include:\n\n- **Local Memory** - semantic recall, trust scoring, sentiment detection, and continuity\n- **Guard System** - checks past mistakes before code changes\n- **Deep Sleep** - overnight consolidation, cleanup, and memory maintenance\n- **Learnings** - error patterns and prevention rules, searchable by category\n- **Session Management** - startup, heartbeat, and multi-session coordination\n- **Reminders & Followups** - tracks user tasks and system verification tasks separately\n- **Entities & Preferences** - remembers people, services, URLs, and observed user preferences\n- **Watchdog** - local reliability checks and recovery signals\n\n## How Memory Works\n\nNEXO keeps local working memory and long-term memory on device:\n\n1. **Recent context** - short-lived session and task state\n2. **Working memory** - active preferences, entities, and decisions\n3. **Long-term memory** - semantic search by meaning with retention controls\n\nDeep Sleep consolidates, prunes, and merges memory so the runtime stays useful without sending private examples to public services.\n\n## Key Tools\n\n| Tool | When to Use |\n|------|------------|\n| `nexo_startup` | Once at session start — registers session, returns active sessions |\n| `nexo_heartbeat` | Every interaction — updates task, checks inbox |\n| `nexo_cognitive_retrieve` | Semantic search across all memories |\n| `nexo_guard_check` | Before editing code — checks for past errors |\n| `nexo_learning_add` | After resolving an error — prevents recurrence |\n| `nexo_session_diary_write` | Before closing session — enables continuity |\n| `nexo_cognitive_trust` | After user feedback — calibrates rigor level |\n\n## Privacy\n\nEverything stays local by default in `~/.nexo/`.

Support and improvement tickets are anonymized: personal names, client data, examples, and private content are not sent.\n\n## More Info\n\n- [GitHub](https://github.com/wazionapps/nexo)\n- [npm](https://www.npmjs.com/package/nexo-brain)\n\nFile v7.38.6:_meta.json\n\n{\n  \"ownerId\": \"kn7bkpq6rs401bknz836vnjshs83ehgm\",\n  \"slug\": \"nexo-brain\",\n  \"version\": \"7.38.6\",\n  \"publishedAt\": 1782617735600\n}\n\nFile v7.38.6:skill-card.md\n\n## Description: <br>\nRuntime core for NEXO Desktop.

Automated \"sleep cycles\" consolidate, prune, and merge memories.\n\n## Key Tools\n\n| Tool | When to Use |\n|------|------------|\n| `nexo_startup` | Once at session start — registers session, returns active sessions |\n| `nexo_heartbeat` | Every interaction — updates task, checks inbox |\n| `nexo_cognitive_retrieve` | Semantic search across all memories |\n| `nexo_guard_check` | Before editing code — checks for past errors |\n| `nexo_learning_add` | After resolving an error — prevents recurrence |\n| `nexo_session_diary_write` | Before closing session — enables continuity |\n| `nexo_cognitive_trust` | After user feedback — calibrates rigor level |\n\n## Privacy\n\nEverything stays local. Two SQLite databases in `~/.nexo/`. No telemetry, no cloud APIs. Vector search runs on CPU via fastembed.\n\n## More Info\n\n- [GitHub](https://github.com/wazionapps/nexo)\n- [npm](https://www.npmjs.com/package/nexo-brain)\n\nFile v7.34.0:_meta.json\n\n{\n  \"ownerId\": \"kn7bkpq6rs401bknz836vnjshs83ehgm\",\n  \"slug\": \"nexo-brain\",\n  \"version\": \"7.34.0\",\n  \"publishedAt\": 1781551074805\n}\n\nFile v7.34.0:skill-card.md\n\n## Description: <br>\nNEXO Brain gives AI agents persistent local memory with semantic retrieval, trust scoring, guard checks, and metacognitive error prevention. <br>\n\nThis skill is ready for commercial/non-commercial use. <br>\n\n## Publisher: <br>\n[wazionapps](https://clawhub.ai/user/wazionapps) <br>\n\n### License/Terms of Use: <br>\nMIT-0 <br>\n\n\n## Use Case: <br>\nDevelopers and agent users use NEXO Brain to add a local MCP-backed memory layer that preserves project context, decisions, reminders, preferences, and error learnings across sessions. <br>\n\n### Deployment Geography for Use: <br>\nGlobal <br>\n\n## Known Risks and Mitigations: <br>\nRisk: The local memory service can retain project context, preferences, entities, reminders, and session history across runs. <br>\nMitigation: Avoid storing secrets in conversations that memory may capture, and review generated ~/.nexo files when higher assurance is needed. <br>\nRisk: Manual setup connects the agent to a local MCP server installed through the nexo-brain package. <br>\nMitigation: Review the npm package and generated server files before connecting the MCP server in sensitive environments. <br>\n\n\n## Reference(s): <br>\n- [NEXO GitHub repository](https://github.com/wazionapps/nexo) <br>\n- [nexo-brain npm package](https://www.npmjs.com/package/nexo-brain) <br>\n- [NEXO Brain ClawHub listing](https://clawhub.ai/wazionapps/nexo-brain) <br>\n\n\n## Skill Output: <br>\n**Output Type(s):** [text, markdown, shell commands, configuration, guidance] <br>\n**Output Format:** [Markdown with inline shell commands and JSON configuration snippets] <br>\n**Output Parameters:** [1D] <br>\n**Other Properties Related to Output:** [May produce and retrieve local memory records through an MCP server backed by files under ~/.nexo.] <br>\n\n## Skill Version(s): <br>\n7.34.0 (source: frontmatter and server release evidence) <br>\n\n## Ethical Considerations: <br>\nUsers should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment. <br>","readmeExcerpt":"Skill: NEXO Desktop Runtime Owner: wazionapps Summary: Runtime core for NEXO Desktop.
