Report #94895

[synthesis] Model refuses to execute dual-use tool calls citing safety, blocking agent workflow

Decouple the generation of the action from the execution in the prompt. For Claude, explicitly state the safety boundaries and that the environment is sandboxed. For GPT-4o, use the Assistants API with code\_interpreter to bypass raw execution refusals.

Journey Context:
If a user asks an agent to write a Python script that accesses the network, Claude 3.5 Sonnet has a much lower refusal threshold for the tool call itself \(e.g., write\_file\), often refusing to output the tool call JSON because it deems the action unsafe. GPT-4o tends to evaluate the intent and will often output the tool call if it is clearly for a benign purpose. This cross-model diff means Claude agents stall on sysadmin tasks unless the system prompt explicitly scopes the environment as a secure, isolated sandbox.
