A common failure mode in LLM applications involves tool calls that appear successful (HTTP 200) but do not actually execute, leading to silent errors where the model may invent information. This issue arises when the tool execution or result injection steps fail, despite the overall request appearing valid. Developers are advised to implement robust logging that tracks the entire tool lifecycle, from request to execution and injection, rather than relying solely on HTTP status codes. AI
