headroom vs ratel
headroom: Headroom compresses everything your AI agent reads — tool outputs, logs, RAG chunks, files, and conversation history — before it reaches the LLM. It achieves the same answers with a fraction of the tokens.; ratel: Ratel is a context engineering layer for AI agents that optimizes tool usage by selecting only relevant tools for each task. It aims to reduce token costs and improve accuracy for LLMs by preventing 'tool overload' without relying on vector databases or embeddings.
