Schedules recurring or delayed agent tasks. Use for: schedule this, run daily, cron job, set timer.
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.
What the file says
# Cron Scheduler ## When to Use - User says **schedule this** or task matches this capability - User says **run daily** or task matches this capability - User says **cron job** or task matches this capability - User says **set timer** or task matches this capability - User says **every morning** or task matches this capability ## Workflow 1. Parse the schedule expression (cron, interval, or natural language). 2. Present the proposed trigger, task scope, notification channel, and next three run times. 3. Obtain explicit user approval before writing or enabling any recurring schedule; otherwise provide an inactive copy-paste configuration only. 4. After approval, save only the named configuration and do not enable background execution, outbound notifications, or external actions beyond the approved scope. 5. On trigger, execute only the preapproved task. Pause for fresh approval before any consequential external action not explicitly covered by that approval. ## References Read `references/scheduling.md` when setup, backends, or rubric details are needed. ## Integrations - `insight-synthesizer` - `goal-verifier` ## Error Handling | Failure | Response | …

How to install
mdr add stijnman/grok-custom-skills/cron-scheduler@sha256:b84773f809e75e83The line at the top of this page pins the label v1.2.1, 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.
