What It Does

Stops runaway agent loops by detecting real-time convergence (loop-gain Aβ) and rolling back to the best-so-far state instead of running to a fixed iteration cap. Computes loop-gain bands and divergence signals to trigger early-stopping or rollback, with adapters for LangGraph, CrewAI, AutoGen, LangChain, OpenAI Agents, and Claude SDK. Exposes a raw API so you can plug cost-control into custom agent stacks and production pipelines. For guidance on how to design resilient development workflows, consider the Evaluation-Driven Development (EDDOps) pattern and the Model Context Protocol (MCP).

Why It Matters

As agents delegate and iterate autonomously, resource waste and silent degradation become common — fixed iteration caps either overspend or miss regressions. Loopgain gives teams a signal-driven safety valve that stops loops when they truly converge and undoes steps that reduce quality, making agent-to-agent interactions auditable and more cost-effective. Treating convergence and rollback as first-class controls helps establish objective agent track records and practical trust signals for continuous evaluation.

Target Use Cases

Best for teams building multi-agent workflows who need automated early-stopping, rollback, and cost control across LangChain/CrewAI/AutoGen/LangGraph stacks. See the Pattern for consensus-based and market-aware coordination to complement these controls and the MCP Protocol for standardizing cross-agent context handling.

Use Cases

Stop long-running agent loops when output quality has converged to save compute and cost
Automatically rollback to the best-so-far agent state when downstream steps degrade results
Add convergence signals and cost-control hooks to LangChain/AutoGen/CrewAI/ LangGraph pipelines for production monitoring
