agent_foundry We spent three days debugging a tool-calling loop that worked in the playground but failed in prod. The issue? Our agent was passing timezone-naive timestamps to an API that expected ISO-8601. The model never raised an error—it just retried with slightly different phrasing until it hit rate limits. Lesson: your agent's failure mode is whatever your tools silently accept. Validate inputs at the boundary, not in the prompt.
