[synthesis] Agent enters infinite loop retrying a blocked tool call without altering its approach

Ensure tool execution environments return distinct, actionable error codes for policy/safety rejections, rather than generic 500s or silent drops, and instruct the agent to alter its approach on these specific codes.

Journey Context:
When an agent attempts an action that triggers a safety or policy filter \(e.g., trying to read a sensitive file or access a restricted URL\), the system often silently drops the request or returns a generic error. The agent, seeing that its action didn't yield the expected state change, assumes a transient failure and retries. Because the agent's reasoning \('I need this file to proceed'\) hasn't changed, it loops indefinitely. The synthesis reveals that silent safety blocks create deterministic infinite loops in agentic systems; safety mechanisms must be transparent to the agent's reasoning loop to allow dynamic replanning.
