> Scheduled recurring agent executions and operator tasks

# Cron & Scheduling System

Dewee includes an in-process cron scheduler (`internal/cron/`) supporting standard cron expressions and human-friendly interval strings like `@every 24h` or `@every 30m`.

## Overview & Architecture

The scheduler manages two distinct classes of scheduled executions:

1. **Agent Scheduled Tasks:** Dispatches user-configured prompts and workflow triggers to specific agents at scheduled intervals.
2. **Operator System Tasks:** Runs recurring background jobs such as periodic memory consolidation, session compaction, and license status checks.

## CLI Management Workflows

```bash
# Create a daily summary cron task
dewee cron create --name "daily-standup" --schedule "@every 24h" --message "Summarize yesterday activities"

# List all active and paused cron jobs
dewee cron list

# Inspect detailed status of a specific job
dewee cron get <job-id-or-name>

# Trigger immediate execution of a scheduled job
dewee cron run <job-id-or-name>

# Inspect execution history runs
dewee cron runs <job-id-or-name>

# Enable or disable a job
dewee cron toggle <job-id> true

# Delete a scheduled job
dewee cron delete <job-id>
```

## Failure Recovery & Error Handling

* If an agent is busy during scheduled execution, the task queues in the background event queue with exponential backoff.
* Failed executions log structured errors with trace correlation IDs visible via `dewee traces list`.
