Windmill

What This Skill Does

The Windmill skill for OpenClaw integrates the powerful Windmill.dev platform directly into your agentic workflows. It allows you to build, deploy, and manage code-first automation workflows and internal tools. By leveraging Windmill’s infrastructure, you can transition from simple scripts to complex, distributed flows without leaving your development environment. This skill acts as a bridge, enabling you to trigger scripts, monitor flow executions, manage secrets, and handle scheduled tasks programmatically.

Installation

To integrate this skill into your environment, use the OpenClaw CLI: clawhub install openclaw/skills/skills/ivangdavila/windmill

Use Cases

• Automated Infrastructure Tasks: Create self-healing workflows that restart services or clean up storage based on health checks.
• Data Pipeline Orchestration: Build robust ETL (Extract, Transform, Load) pipelines that handle retries and error logging gracefully.
• Custom Internal Tooling: Generate UI-backed scripts for non-technical team members to trigger business logic safely.
• Scheduled Monitoring: Set up recurring checks for system health or webhook-triggered API operations.

Example Prompts

1. "Windmill, create a new flow that scrapes our production logs, filters for errors, and sends an alert to Slack."
2. "Windmill, check the status of my 'user-sync' flow and let me know if any steps failed during the last run."
3. "Windmill, update the resource configuration for our database credentials and trigger the staging deployment workflow."

Tips & Limitations

Success with Windmill requires attention to architectural details. First, always test individual scripts before nesting them into flows to isolate potential logic bugs. Regarding state, remember that workers are stateless; always persist required data in external databases or Windmill variables.

Be mindful of execution context: if you are using TypeScript, note that it runs on Bun, so Node.js-specific native modules might not behave as expected. When defining schemas, ensure your function signatures provide clear type hints, as the UI form generation depends entirely on them. Finally, observe security best practices by strictly separating sensitive credentials into 'Secrets' rather than 'Variables,' as the latter are visible in plain text within the dashboard. Always define timeouts for your suspend steps; otherwise, your flows risk hanging indefinitely, consuming worker capacity and preventing future executions from completing. When scaling, remember that one worker equals one concurrent execution slot, so adjust your infrastructure size according to your parallel processing needs.
