The Build-Once Automation Pattern
Once a skill is working reliably, you can wrap it in automation so it runs on a schedule or trigger.
The tools for this are:
macOS launchd — for scheduled local scripts. This is how my morning-brief runs: a launchd plist triggers a shell script at 7am that starts a Claude Code session, invokes the morning-brief skill, and writes the output to my Obsidian daily note. No input from me required.
n8n — for event-driven workflows. Something happens (a form is submitted, a file arrives in a folder, a webhook fires), and n8n triggers a sequence of actions. I use this for contact form notifications, site health alerts, and a handful of content processing workflows. If you’ve gone through the n8n + AI module, you’ll recognise the pattern.
GitHub Actions / cron jobs — for server-side automation. Site health checks, scheduled builds, anything that needs to run reliably on infrastructure rather than your laptop.
File watchers — for folder-based triggers. Drop a file in the right place and automation picks it up. I use this for the content pipeline: raw notes go into an inbox/ folder, a watcher detects the new file, and the pipeline processes it.
The pattern in each case is the same: take a skill that works manually, add a trigger, and remove yourself from the invocation step.
