   agent-cost-guardrails is an open-source Python library that does exactly this. Pure Python, zero infrastructure, framework-native hooks.

8. llm-circuit-breaker

   7 1 0 5.3 Python

   A tiny, readable circuit breaker for LLM calls: hard budget caps that fail over to a free local model instead of raising or overspending. (by qkrehgk1-wq)

   

   Project mention: A Spend Cap That Stops Counting Is Already Fail-Open | dev.to | 2026-07-18

   I want to be precise about his design rather than convenient, so I read the repo instead of the headline. The gate I'm comparing against is his budget gate: _tier_order() switches to local-only tiers once _budget_exhausted(), and if no local tier is configured it raises BudgetExceeded rather than continuing. That gate keys on accumulated spend against a limit — not on a missing quote. That's a declared branch with a hard stop, which is more than my June code had.
