# NousResearch/hermes-agent · Cron schedule re-parse round-trip idempotency fix

## Open now

- 1 issue, 2 PRs open on GitHub.
- #89560: cron: parse_schedule emits "once at"/"once in" displays it cannot re-parse (one-shot cron edit → ValueError/500)
- PR #89563: fix(cron): re-parse the serializer's own once-at/once-in displays
- PR #89568: fix(cron): re-parse own display formats for round-trip idempotency

These issues and PRs address a bug where cron schedule parsing emits 'once at'/'once in' display strings that it cannot subsequently re-parse, causing errors on edit. The work focuses on making the serializer's output round-trip safely through parse_schedule.
