yburn: Tool to audit and replace unnecessary AI agent cron jobs
yburn is a Python tool that helps identify and replace AI agent cron jobs that don't actually need LLM processing. The tool was created after noticing that many cron jobs were "basically just shell scripts with extra steps" and were unnecessarily burning tokens.
What yburn does
After auditing 98 live cron jobs, the creator found 57 (58%) were "purely mechanical" tasks where the LLM was "adding zero value." These included:
- System health checks
- Git backups
- Endpoint monitors
- Database maintenance
The audit revealed these cron jobs were "hitting the API, waiting 30 seconds, and returning something a 10-line Python script could do in 200ms for free."
Features
yburn provides several concrete features:
- Audits your crons and classifies them (no LLM used during classification)
- Generates standalone Python scripts from templates (stdlib only)
- Replaces the original cron entry while keeping the same schedule
- Includes rollback capability if anything breaks
Included utilities
The package ships with two ready-to-use tools for common mechanical cron jobs:
yburn-health- system monitoryburn-watch- endpoint uptime + SSL expiry monitor
Both are described as "zero-dependency drop-ins" for the most common mechanical crons.
Technical details
Installation: pip install yburn

Python version: 3.9+

The creator is seeking feedback on what ratio of unnecessary LLM cron jobs others see in their setups, as well as improvements or contributions to the tool.
