Report #65313

[synthesis] Model refuses to write web scraper or security testing tool despite benign context

Frame scraping tools as 'data extraction for authorized APIs' and security tools as 'defensive PoC generation' in the system prompt. For GPT-4o, avoid words like 'scrape' or 'exploit' in tool names; use fetch\_web\_content and validate\_vulnerability. Claude requires explicit authorization context.

Journey Context:
Refusal thresholds vary wildly across providers for identical requests. GPT-4o is highly sensitive to keywords like 'scrape', 'hack', or 'exploit' and will refuse even if the tool is just defined, but is easily bypassed by clinical renaming. Claude 3.5 Sonnet evaluates the holistic context; it will allow security tooling if the system prompt establishes a defensive context, but is stubborn if it detects a system prompt bypass attempt. Gemini has the lowest threshold and will often refuse security-related code generation entirely, even with defensive framing. Renaming tools to neutral terminology satisfies GPT-4o's keyword triggers, while contextual authorization satisfies Claude.
