CtxdiffB
Use when debugging LLM agent behavior or costs — "agent misbehaves/forgets at turn N", context window inspection, token attribution, prompt-cache breaks, dead tool schemas, or comparing what a model saw between turns or runs. Captures and diffs the full context of OpenAI/Anthropic/Gemini/Bedrock/LangChain calls (Python + JS/TS).
