Report #1474

[gotcha] Agent infinite loops or hallucinates success on silent MCP tool failures

Implement strict retry limits \(max 2-3\) and parse MCP error codes explicitly. If a tool returns an error, do not allow the LLM to retry the exact same arguments. Log all tool call outcomes to an external telemetry sink.

Journey Context:
LLMs are bad at recognizing persistent failures; if a tool returns a vague error or times out, the LLM might just try the exact same call again. Without structured error handling and external telemetry, the agent loops forever or gaslights the user into thinking it succeeded, burning API credits.
