Summary
Exact prompt
# Task: fix the cron schedule calculator `cron.py` has a function `next_fire(expr, after)` that should return the next time a cron schedule fires, but it gets many schedules wrong and is too slow for rare schedules. Fix it (rewrite freely) so it follows every rule below exactly. Python standard library only. Keep the function name and signature. No network. ## Rules 1. `expr` has exactly 5 whitespace-separated fields: minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, where both 0 and 7 mean Sunday, 1 = Monday ... 6 = Saturday). Leading/trailing whitespace and multiple spaces between fields are allowed. 2. Each field is a comma-separated list of items. An item is `*`, a number `n`, a range `a-b` (inclusive, requires a <= b), or any of those followed by `/step` (step >= 1): `*/s` = every s-th value starting at the field minimum, `a-b/s` = a, a+s, ... up to b, and `a/s` = a, a+s, ... up to the field maximum. 3. Month names `JAN`-`DEC` and day names `SUN`-`SAT` may be used anywhere a number may be used in the month and day-of-week fields (including in ranges, e.g. `MON-FRI`), case-insensitive. 4. Macros (case-insensitive) replace the whole expression: `@yearly` and `@annually` = `0 0 1 1 *`, `@monthly` = `0 0 1 * *`, `@weekly` = `0 0 * * 0`, `@daily` and `@midnight` = `0 0 * * *`, `@hourly` = `0 * * * *`. 5. Day matching: if BOTH day-of-month and day-of-week are restricted (the field text is not exactly `*`), a day matches when EITHER field matches. If only one of them is restricted, only that one counts. A field like `*/1` or `1-31` counts as restricted. 6. `after` is a naive `datetime`. Return the earliest matching minute STRICTLY after `after`, as a naive `datetime` with seconds and microseconds 0. (If `after` is 10:00:30 and the schedule fires every minute, the answer is 10:01:00.) No time zones, no DST: treat times as plain calendar times. 7. Raise `ValueError` for: wrong number of fields, unknown macro, any value outside the field's range, `a > b` in a range, step 0 or a non-numeric step, empty items (e.g. `1,,2`), unknown names, or any other unparsable text. 8. If the schedule can never fire within 5 years after `after` (e.g. `0 0 31 2 *`), raise `ValueError` instead of looping forever. A schedule that fires only on 29 February must still be found (it is at most ~4 years away). 9. Every call must return (or raise) within 1 second on an ordinary machine, including the leap-day case. The grader runs a hidden unittest suite that checks exactly these rules.
The starting code ANDs day fields, ignores names/macros/7=Sunday, is inclusive of 'after', accepts invalid fields and scans minute by minute (too slow / never terminates for rare schedules). Each rule has exact expected datetimes. Original benchmark task written for usecaserank.com. Headless, offline run on a reproducible fixture. Cost shown is a list-price API-equivalent estimate (run on a ChatGPT subscription, not billed).
Success criteria: 1. All 8 hidden unittest cases pass (strictly-after semantics, lists/ranges/steps incl. a/s, month/day names, 0 and 7 = Sunday, macros, DOM/DOW OR rule incl. */1 as restricted, 18 invalid expressions raise ValueError, never-firing schedule raises within 1 s, 29 Feb found within 1 s).
Setup notes: Use Case Scout batch7 case g01-cron-next-fire (offline fixture). Prepared with batch7/prepare.sh on the shared box; only TASK.md + starting files were copied to the agent machine, hidden key/tests stayed on the box. Prompt = TASK.md verbatim on stdin. Flags: --json -s workspace-write --skip-git-repo-check --ephemeral --ignore-user-config --ignore-rules -C <workdir>. Scored on the box with the scout's scorer: `python score.py WORKDIR KEYDIR`. Single run, no retries. User-level AGENTS.md (846 bytes, sha256 83ec4fe50da8) may have been in context; --ignore-user-config does not document excluding it. Serving model not confirmed: requested via -m; the event log does not echo the serving model id. Price source is secondary (pricing.json verification='secondary', https://www.actuia.com/en/news/ai-api-pricing-in-october-2026-050-to-50-for-output/), not an official OpenAI price page. Score: 8/8. Cost is an ESTIMATE: measured tokens x pricing.json list price (ChatGPT plan, nothing billed); input_tokens include cached reads; output_tokens include reasoning tokens. Tool calls 5 (1 failed, recovered). Single run.
