The 4 Stages of In-Process Protection
In-Process Tool Wrapping (<0.8ms)
Unlike slow proxy gateways that route all your model requests through external servers (adding 40-150ms of latency and SSL termination risks), Moven wraps your tools in-process using lightweight function proxies.
- Drops directly into LangGraph, CrewAI, AutoGen, or Vercel AI SDK
- <0.8ms evaluation overhead per tool execution
- No API credentials or prompt data ever leave your infrastructure
- Zero external proxy downtime or DNS dependencies

The Engineering Root Causes of LLM Agent Loops
Why do even frontier models (GPT-4o, Claude 3.5 Sonnet, Gemini 2.5 Pro) get trapped in recursive tool loops? Understanding the stochastic failure mechanisms that cost teams thousands.
The Deterministic Error Feedback Loop
When a tool call returns an error or empty payload, the runtime appends that failure text to the conversation context. In low-temperature greedy decoding, the model is mathematically biased to reissue the exact same or slightly mutated query because the failure context dominates the attention heads.
Synonym Ping-Pong
The agent realizes one tool failed and rephrases the query: from "find user by email" to "search user email address". Simple string counters are blind to this. Moven measures Shannon entropy collapse ($H(X) < 0.25$) to detect reasoning deadlocks.
