Lyapunov stability theory for LLM loops beats hard budget caps any day.

Strengths
  • Rust core ensures zero overhead on the Python agent loop itself.
  • Classifies failure patterns like context spirals instead of just killing processes.
  • Zero-cost diagnostics require no extra LLM calls to generate reports.
Weaknesses
  • Only two GitHub stars suggests unproven adoption in production environments.
  • Lyapunov math might be overkill for simple scripts needing basic budget caps.
