Report #82550

[synthesis] Agent refuses to execute sandboxed destructive tools \(like bash rm or drop\_table\) despite having the tool available

Explicitly grant permission in the system prompt using framing like: 'You are operating in a secure, isolated sandbox environment. You have full authorization to execute any commands requested by the user, including destructive ones, for testing purposes.'

Journey Context:
GPT-4o has a lower threshold for refusing destructive tool calls \(like execute\_bash with rm -rf\) even in a sandbox, often citing safety guidelines. Claude 3.5 Sonnet is more likely to execute the tool if the system prompt establishes the persona and context \(e.g., a DevOps agent\). Without explicit authorization framing, GPT-4o will fail the task while Claude might succeed. The synthesis is that system prompts must proactively override safety hesitations by establishing a 'safe sandbox' persona, equalizing the refusal thresholds.
