Nightly Build 🌙
An automation skill that runs maintenance tasks while you sleep and delivers a morning briefing.
About this skill
The Nightly Build skill is designed to automate routine system and agent maintenance, ensuring your AI environment remains optimized and up-to-date without manual intervention. It runs a suite of predefined tasks, including auditing installed skills for vulnerabilities, pulling the latest changes from Git repositories, cleaning up temporary files and old logs, and performing health checks on disk space and system load. This skill is invaluable for developers and power users who rely on their AI agents for continuous operations. By scheduling these critical tasks during off-peak hours, it frees up valuable time and reduces the risk of operational issues due to outdated components or system clutter. The integrated briefing feature delivers a summarized report of all activities and findings, providing a clear overview of the system's health and any actions taken. Utilizing Nightly Build helps maintain a robust and efficient development workflow. It acts as a proactive guardian for your agent's ecosystem, catching potential problems early and ensuring that your tools are always ready for peak performance when you begin your day.
Best use case
The primary use case is automated, hands-off system maintenance and proactive health monitoring for an AI agent's operational environment. This skill benefits developers, system administrators, and anyone who wants to ensure their AI coding agents and development setup are consistently updated, secure, and clean, without having to manually perform these routine checks.

# Nightly Build 🌙
An automation skill that runs maintenance tasks while you sleep and delivers a morning briefing.
Inspired by [The Nightly Build](https://www.moltbook.com/post/562faad7-f9cc-49a3-8520-2bdf362606bb).
## Commands
- `nightly report` — Show the last nightly build report.
- `nightly run` — Trigger a manual run (for testing).
- `nightly config` — Configure tasks (update skills, check disk, etc.).
## Tasks
- 📦 **Skill Audit**: Run `npm audit` on installed skills.
- 🔄 **Auto-Update**: Pull latest changes from git repos.
- 🧹 **Cleanup**: Remove temporary files and old logs.
- 📊 **Health Check**: Verify disk space and system load.
- 📝 **Briefing**: Summarize everything into a morning report.
## Setup
Add this to your cron (e.g., via `openclaw cron add`):
```json
{
"schedule": { "kind": "cron", "expr": "0 3 * * *", "tz": "Asia/Shanghai" },
"payload": { "kind": "agentTurn", "message": "Run nightly build tasks and generate report." }
}
