Cron Doctor

lingxling/cron-doctor

Diagnose and validate cron expressions before they ship. Catches the five silent death-traps: impossible dates that never fire, OR-semantics that fire too often, midnight spikes, uneven step drift, and leap-year February 29.

Install

one command, takes just this skill from the repository 
npx skills add https://github.com/lingxling/awesome-skills-cn --skill cron-doctor

How to use it

Copy the folder

Take lingxling/cron-doctor from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npm. Without those the skill loads but fails at the first command.
