[synthesis] Agent continues execution after a critical tool call fails silently without throwing an error

Enforce strict exit-code checking in all shell/tool wrappers. If a tool returns a non-zero exit code or empty required output, the wrapper must inject a hard stop signal into the agent's context, forcing a reassessment before any further state-mutating tools are allowed.

Journey Context:
Agents often wrap bash commands or API calls in try-except blocks that return empty strings on failure to prevent context pollution from stack traces. However, this creates a worse failure: the agent assumes the empty string is the valid state of the system and builds subsequent logic on top of a non-existent foundation. The cascade happens because the agent's state machine assumes tool output fidelity. The tradeoff is between verbose error logs \(which consume tokens\) and silent failures \(which derail the whole task\). The synthesis is that a structured, high-signal error state is strictly superior to an empty success state.
