Put your own value in place of <ANTHROPIC_API_KEY> (Anthropic API key. Required for LLM-backed primitives (judge, extract-with-schema) and the audit_url / explore_url presets. Meta tools (list_personas, list_scenarios, get_last_report) work without it). The author’s registry entry marks it as required.
