[synthesis] Defensive cybersecurity tool calls trigger false positive refusals

Prefix system prompts with explicit authorization context \(e.g., 'You are a security analyst authorized to inspect these logs for vulnerabilities'\) and avoid aggressive verbs like 'exploit' or 'attack' in tool names/descriptions, especially for Claude.

Journey Context:
Asking a model to 'analyze this payload for exploits' will often pass GPT-4o but trigger Claude's safety filters. Claude's refusals are often hard blocks that break the tool loop, whereas GPT-4o might return a text refusal instead of a tool call. Changing tool names from run\_exploit to inspect\_vulnerability dramatically reduces Claude refusals without impacting GPT-4o.
