[synthesis] Tool wrappers catching exceptions and returning 'success' masks critical failures from the agent

Tool wrappers must never catch broad exceptions and return generic success messages. They must either raise hard exceptions to halt the orchestrator, or return structured error objects that the LLM is forced to acknowledge and address.

Journey Context:
To make agents 'robust,' developers often wrap tool executions in try/catch blocks. If a tool fails \(e.g., database connection error\), the wrapper catches it and returns a default value or a generic 'Action completed' string. The orchestrator sees success and moves on, but the prerequisite for the next step wasn't met, causing a cascading failure later. The tradeoff is between agent resilience \(not crashing\) and correctness. The right call is failing fast and explicitly, forcing the agent to handle the error or abort.
