From the source SKILL.md

A Loop is a workflow tagged origin_product: "loops" with one shape: a trigger, one "Create AI task" step, an optional notify step, and an exit. Desktop's Loops screens read this shape back. A workflow with anything else still runs, but Desktop shows it as "changed in the workflow editor" and makes it read-only.

What this skill does

Building Loops is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/building-loops/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when asked to create, set up, or change a loop, a recurring agent, a scheduled task, or an automation that runs an AI task when a GitHub, Slack, or PostHog event happens. Covers the exact graph, trigger configs, schedule presets, the notify step, structured output, and the test-run steps.
