Do these 4 steps to stop Fable 5.1 from wiping out your weekly credits:

1. Set /effort to low
2. Run /claude-api cost-optimize to find the biggest wastes
3. Run /claude-api prompt-audit to clear old junk
4. Run /claude-api migrate this project to claude-fable-5-1 to update old model ids

You won’t have to worry about wasting tokens anymore.
