OpenClaw Heartbeat Cost Audit Prompt & Findings
A detailed write-up of discovering runaway heartbeat costs (~$2/day on useless polls, 62/63 doing nothing, context growing across polls). Includes a ready-to-paste read-only audit prompt for Claude Code that inventories cron, heartbeats, launchd/crontab, and standalone scripts; ranks cost; checks for context contamination and silent “OK” replies; and outputs a markdown report with ranked fixes. New rules suggested: never change model in place, log healthy checks, isolate sessions.
Why it matters
Recurring model calls are the silent budget killer for always-on agents. The prompt is immediately actionable and the war story is relatable. Strong operational hygiene content.
