Cron Hardening
Reliable cron config learned through repeated failures. Follow these rules for every new cron.
1. PIN the model
Every cron that delivers to the user must explicitly set a fast model. The global default can get stuck on model resolution (MiniMax cold-start especially).
"model": "deepseek/deepseek-v4-flash"
Time-sensitive crons that need pinning:
- Expense check-ins (10am, 1:30pm, 10pm)
- Expense sync (9:30am)
- News briefings (7:30am, 3pm, 10pm)
- Investment check-in (Sat 10am) and sync (Sat 11am)
- Transport check-in (9am)
Non-time-sensitive crons (dashboard, backup, security audit) can use default model — delay is harmless.
2. Absolute paths only
Cron agentTurn payloads run in an isolated context. They cannot cd to the workspace first. Every command MUST use absolute paths.
WRONG:
cd /workspace && python3 scripts/sync.py
RIGHT:
/usr/bin/python3 /home/hobopi/.openclaw/workspace/scripts/sync-ledger-to-sheet.py
Preflight checks reject cd && python3 chains.
3. Timeouts
| Cron type | Timeout | Reason |
|---|---|---|
| Expense check-in | 300s (600s for 10pm) | May wait for Hobo reply |
| News briefing | 600s | Web search + curation takes time |
| Expense sync | 60s | Quick script, just needs to run |
| Investment sync | 600s | Reads all ledger files |
| Dashboard gen | 180s | Runs 3 scripts in sequence |
| Token tracker | 300s | Heavy usage data parsing |
| Transport check-in | 600s | Previous-day ask, may wait |
| Backup | 300s | tar + gzip |
| Security audit | 600s | Full healthcheck |
4. Delivery config
For crons that deliver to Telegram, use explicit delivery:
"delivery": {
"mode": "announce",
"channel": "telegram",
"to": "telegram:37134287"
}
mode: "none" for crons that don't need to notify the user (dashboard updates, token tracking).
5. Failure recovery
- Check
lastRunStatusandconsecutiveErrorson cron status lastDiagnosticsshows the error phase:model-call-started= model resolution timeout- Common fixes: pin model, bump timeout, check absolute paths
- After fixing, next scheduled run uses new config (no manual trigger needed)
6. maxConcurrentRuns
Set cron.maxConcurrentRuns in openclaw.json when multiple crons fire simultaneously:
"cron": { "maxConcurrentRuns": 2 }
Prevents Sunday 5am clash (security audit + hourly dashboard + expense check-in).
7. Failure alerts
"failureAlert": {
"after": 2,
"mode": "announce",
"channel": "telegram",
"to": "telegram:37134287"
}
Notifies Hobo after 2 consecutive failures. Default enabled.
