[synthesis] Partial task success masks total agent failure when tool errors are silent

Mandate explicit verification tool calls \(e.g., test, ls, cat\) after mutation tool calls, and structure the agent's final response to require a checklist of all sub-task verifications, not just plan execution.

Journey Context:
Developers often rely on tool exit codes or exception handling to catch failures. However, in agent workflows, tools can fail silently \(e.g., writing an empty file due to a permission error that is swallowed\). The agent sees 'file written' in its thought process and moves on. The synthesis is that an agent's plan execution is not task completion; verification must be a distinct, mandatory step in the agent's control flow, separate from the action itself.
