Your Claude Code bill shouldn't be unpredictable. But for most developers, it is. One week you're within budget, the next you've burned through your entire monthly allocation in 3 days.
We've tracked 76+ GitHub Issues related to cost spikes, and after analyzing hundreds of sessions, here's what's actually causing the volatility — and how to fix it.
Auto-compact is designed to save context. But when the recovery system degrades, it enters an infinite loop. One user lost their entire overnight budget to 15+ consecutive compactions with zero work done (#51088).
Cost impact: 100% of daily budget consumed while you sleep.
The reasoning phase has no built-in token ceiling. One Sonnet 4.6 user saw 16 million tokens consumed in 25 minutes of thinking with no useful output (#51092).
Cost impact: Entire weekly quota in a single session.
Claude attempts a 1-line CSS change, fails, and retries 10+ times with the same approach. Each retry consumes tokens but makes zero progress (#50986).
Cost impact: Weekly budget burned on a trivial edit.
Claude reads file after file, runs 40+ Glob/Grep searches, but never writes anything. Your budget drains on "understanding" without action (#51054).
Cost impact: 20% of weekly budget on a simple task.
Sub-agents spawn without inheriting your safety rules. They hit file conflicts and enter endless retry loops, burning 101K+ tokens on operations that should cost 5K (#46968).
Cost impact: 10-20x expected token consumption.
Each of these patterns can be detected and stopped by a simple bash hook that runs in <50ms:
