troubleshoot

Diagnose and fix a failing or misbehaving Atomic Agents app — import errors, schema validation failures, empty or malformed LLM output, provider role/mode errors, history and context problems, MCP transport errors. Use when the user reports an error, traceback, or wrong behavior in atomic-agents code, asks "why is my agent not working / crashing / returning garbage", or pastes a ValidationError, ImportError, or provider API error from an atomic-agents project.
