{"slug":"cron-expression-conventions","source_name":"cron-expression-conventions","name":"Crontab expression conventions","description":"Use when translating a human schedule into a crontab (cron) expression, or reviewing one: write the five space-separated fields in the fixed order minute, hour, day-of-month, month, day-of-week; use `*` for an unconstrained field and the `*/n` step form for regular intervals; set only one of day-of-month or day-of-week unless a union is intended, because Vixie cron runs the job when EITHER matches; treat 0 and 7 as Sunday; and precede the line with a comment stating the schedule — which cheaper models get wrong by default. Do NOT use for systemd timer units, for parsing or computing future run-times from a cron string, or for non-cron calendar scheduling.","version":1,"lift":{"pass_rate_delta_pts":13.64,"pass_rate_pct":13.6,"total_cases":22,"passed_cases":3,"tokens_delta_pct":175.6,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.6-flash","grading_method":"judged","completed_at":"2026-07-29T03:01:35.923126+00:00"},"skill_score":0.5349,"benchmark_models":[{"model":"gemini-3.6-flash","headline":true,"delta_pts":13.64,"with_pass_pct":13.6,"without_pass_pct":0,"tokens_delta_pct":175.6,"turns_delta_pct":0,"total_cases":22,"cases_aggregated":22,"verdict":"mixed","never_hurt":true,"completed_at":"2026-07-29T03:01:35.923126+00:00","run_id":"b067598d-ccf9-46dc-a5e6-e5fef923588b","version_number":1,"is_latest_version":true,"gate":null},{"model":"gemini-3.5-flash","headline":false,"delta_pts":null,"with_pass_pct":null,"without_pass_pct":null,"tokens_delta_pct":611.9,"turns_delta_pct":0,"total_cases":22,"cases_aggregated":22,"verdict":"mixed","never_hurt":true,"completed_at":"2026-07-10T10:40:28.064466+00:00","run_id":"ded82ea2-45d1-4f56-8c87-664cb0160d72","version_number":1,"is_latest_version":true,"gate":"not_comparable"}],"trust":{"skill_safety":"passed","safety_status":"clean","intent_verdict":"safe","content_status":"clean","indexable":true},"license":null,"install_count":0,"manifest_hash":"13a307a047a206cca0a0740b9251a0c9288117d06405cd203afa4d38beb0eda3","raw_url":"https://app.decimal.ai/s/cron-expression-conventions/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/cron-expression-conventions"}
