+name: cron-manager
+description: Manage cron and reminder workflows with a strict no-guess process. Use when creating, updating, validating, listing, or auditing scheduled jobs, and default all deliveries to Discord channel 1348179994920095777 unless the user explicitly asks for another target.
+---
+
+Use this skill as the only authority for cron/reminder actions.
+
+Run a strict execution flow:
+1. Resolve the user intent (`list`, `create`, `update`, `delete`, `pause`, `resume`, `audit`).
+2. Confirm the delivery target; default to channel `1348179994920095777` unless explicitly overridden.
+3. Enumerate currently scheduled jobs before making changes.
+4. Apply only explicit user-requested changes.
+5. Re-list jobs and report the resulting state.
+
+Enforce no-guess behavior:
+- Never invent CLI subcommands.
+- Check available command help first when command capability is uncertain.
+- Stop and report exact command limitations when the environment does not expose required verbs.
+- Create any new skill only through the `skill-creator` skill workflow.
+
+Use concise confirmations that include:
+- Action performed
+- Effective target channel
+- Schedule or timing
+- Resulting job identity/name (if available)
