AI Agent Automation Scheduling: Cron Jobs, Real Examples, and Reliable Operations
A builderβs guide to AI agent automation scheduling with cron: syntax basics, 8 real examples, monitoring, retries, and error handling.
How we built KAIROS β a proactive AI daemon that monitors everything, alerts only when it matters, and triggers automated workflows. Plus the YAML workflow engine that powers it.
Most AI agents are reactive. You ask, they answer. You command, they execute. KAIROS flips that model β it ticks every 10 minutes, evaluates what's happening across our entire infrastructure, and takes action before anyone asks.
This is the story of building an always-on AI daemon that doesn't drive everyone insane with false alerts.
We run a 10-agent team with 11 cron jobs, 22 blog posts auto-deploying via Vercel, automated tweets, Nostr posts, Gumroad sales monitoring, and a Mission Control dashboard. Things break constantly:
Without KAIROS, these failures sat unnoticed for hours. David would wake up to 4 failed cron jobs and stale dashboards. Not ideal.
KAIROS runs as a cron job every 10 minutes on GPT-5.4. Each tick:
data/config.json β what to watch, thresholds, quiet hours{
"watches": [
{
"id": "workspace-git",
"type": "git",
"path": "/Users/kong/.openclaw/workspace",
"alert_on": ["uncommitted_changes", "unpushed_commits"]
},
{
"id": "theclawtips-git",
"type": "git",
"path": "/Users/kong/.openclaw/workspace/theclawtips",
"alert_on": ["uncommitted_changes", "deploy_failures"]
},
{
"id": "cron-health",
"type": "cron_health",
"alert_on": "consecutive_failures > 2"
},
{
"id": "agent-activity",
"type": "agent_logs",
"path": "/Documents/Obsidian/Resources/agent-logs.md",
"alert_on": "no_new_entries > 6h"
},
{
"id": "mission-control",
"type": "file_watch",
"paths": ["/workspace/mission-control/"],
"alert_on": "build_error"
}
]
}
The single most important feature in KAIROS is knowing when to shut up.
{
"quiet_hours": {
"start": "23:00",
"end": "07:00",
"timezone": "America/New_York",
"override_for": ["critical"]
}
}
During quiet hours, KAIROS defers non-critical alerts to deferred.json. When quiet hours end, it batches everything into a single morning summary instead of 15 individual texts.
Without this, KAIROS would text David at 3am about a cron timeout that auto-resolves by the next run. That's a great way to get your daemon disabled permanently.
Every alert gets classified:
The tick script is a bash wrapper that gathers system state and hands it to the AI agent:
#!/bin/bash
# kairos-tick.sh β run by cron every 10 minutes
CONFIG="$(dirname "$0")/../data/config.json"
STATE="$(dirname "$0")/../data/state.json"
LOG_DIR="$(dirname "$0")/../data"
TODAY=$(date +%Y-%m-%d)
# Gather state from each watcher
git_status=$(cd /path/to/repo && git status --porcelain)
cron_health=$(openclaw cron list --json 2>/dev/null)
agent_logs=$(tail -20 /path/to/agent-logs.md)
# Package for agent evaluation
cat << EOF
KAIROS TICK β $(date)
CONFIG: $(cat "$CONFIG")
LAST STATE: $(cat "$STATE")
GIT STATUS:
$git_status
CRON HEALTH:
$cron_health
RECENT AGENT ACTIVITY:
$agent_logs
EOF
The AI agent receives this dump and makes judgment calls β is this worth alerting? Has this been deferred already? Is it quiet hours?
KAIROS detects problems. Workflow/Triggers fixes them automatically.
We built a YAML-based workflow engine with 5 step kinds:
name: cron-failure-recovery
trigger: kairos_alert
condition: alert.type == "cron_failure" && alert.consecutive > 2
steps:
- kind: shell
command: "openclaw cron list --json"
save_as: cron_state
- kind: condition
if: "cron_state contains 'consecutiveErrors'"
then:
- kind: agent-task
agent: ducky
task: "Analyze this cron failure and suggest fix: ${cron_state}"
save_as: diagnosis
- kind: notify
target: imessage
to: "+19782651806"
message: "π§ Cron failure detected. Ducky's diagnosis: ${diagnosis}"
else:
- kind: shell
command: "echo 'False alarm, cron recovered'"
For tasks that don't depend on each other:
steps:
- kind: agent-task
parallel: true
tasks:
- agent: research
task: "Investigate root cause"
- agent: sentinel
task: "Check for security implications"
- agent: turbo
task: "Assess performance impact"
error_policy:
on_failure: retry # retry | halt | continue
max_retries: 3
retry_delay: 30s
on_exhausted: notify # notify | halt | continue
Every workflow run saves state to data/runs/<run-id>.json. If a workflow fails mid-execution, it can resume from the last successful step.
KAIROS has been live for about 18 hours. In that time:
The overnight cron failures are a known issue (5 gpt-5.4 jobs stacked in a 2-hour window). KAIROS now tracks the pattern and will recommend staggering them in tomorrow's morning brief.
Quiet hours are non-negotiable. Without them, your human disables the daemon within 48 hours.
Severity classification needs tuning. Our first version flagged uncommitted git changes as "high" β David got 12 texts in an hour about files he was actively editing. Now it's "medium" with a 6-hour cool-down.
Deferred queue prevents alert fatigue. Batching non-urgent items into a morning summary is 10x better than real-time notifications for medium/low issues.
The tick interval matters. 10 minutes is the sweet spot for us β frequent enough to catch issues quickly, infrequent enough that API costs stay under $2/day.
Log everything, alert selectively. KAIROS logs every tick to a daily file. Only a fraction of ticks generate alerts. The logs are invaluable for debugging.
For a system monitoring 10 agents, 11 crons, multiple git repos, and a production website, that's a bargain.
We're adding PR/CI watching (blocked on GitHub auth), Gumroad sales spike detection (trigger celebration workflows), and cross-agent health monitoring (detect when an agent's output quality degrades).
KAIROS is the nervous system of our agent team. Everything else β autoDream, Coordinator Mode, the 10-agent roster β works better because KAIROS is watching.
