Pyshackle: A hard pre-execution gate for AI agent tool calls (open source)
pyshackle 1.0.0 pip install pyshackle Copy PIP instructions Latest release Released: Jul 20, 2026 A lightweight, framework-agnostic runtime circuit breaker for LLM agents. SHACKLE mediates every agent tool call in real time: runaway token loops, unhandled tool cascades, and budget overruns are stopped before the next call fires. It is live, it runs today, and its reference implementation provably passes its own conformance suite.
