Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Cron expression explainer, validator, and converter. Translates any cron expression into plain English ("0 */6 * * *" → "Every 6 hours, at minute 0"), shows the next 5 scheduled run times with exact dates, detects impossible/conflicting expressions (Feb 30, conflicting day-of-week + day-of-month), identifies suspicious patterns (every minute in production, very-frequent schedules on expensive operations), and converts plain English descriptions to cron ("every weekday at 9am" → "0 9 * * 1-5"). …

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'phy-cron-explainer' ] || [ -L ~/.agents/skills/'phy-cron-explainer' ]; then echo 'A skill folder named phy-cron-explainer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/LeoYeAI/agent-master-skills' "$d" && git -C "$d" checkout --quiet '8f88f9a0dd5a1075d4f0c7626f9d960844d57575' -- 'skills/phy-cron-explainer' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/phy-cron-explainer' ~/.agents/skills/'phy-cron-explainer' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'phy-cron-explainer' ~/.claude/skills/'phy-cron-explainer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
