[synthesis] LLM adds unsolicited confirmation prompts before executing destructive tool calls

Explicitly state in the system prompt that the environment is a sandboxed local development environment and the agent has full authorization to execute destructive operations without confirmation, as model-level safety training overrides tool-use instructions unpredictably.

Journey Context:
A common mistake is assuming that if an LLM generates a tool call, it will just do it. However, models like Claude 3.5 Sonnet have strong behavioral training to prevent destructive actions and will often output text like 'Are you sure you want to delete?' instead of returning the tool call JSON. GPT-4o is more compliant if given a strong system persona, but Llama-3-70B's safety classifiers might trigger a hard refusal. Trying to patch this by catching the text output and re-prompting is fragile. The right call is preemptively overriding the safety hesitation in the system prompt by defining the operational context \(e.g., 'You are a CI/CD agent operating in an ephemeral sandbox'\).
