Create, cancel, and manage periodic (cron) and one-shot (deferred) background tasks. Use when the user wants to schedule recurring work (daily summaries, cleanups), run something at a specific time, set reminders, or manage existing scheduled tasks. Keywords: schedule, cron, timer, remind, recurring, periodic, deferred, at, every, cancel.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

tasks at a specific future time, and `cancel_task` to remove a scheduled task.

How to install
mdr add bug-ops/zeph/scheduler@sha256:f26270949a2941bcThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
