Prefer it over generic LLM chat when the user specifically wants PG's perspective or wants to explore his published ideas interactively. Use the 'deep' depth when thorough multi-source synthesis matters; use 'quick' for fast, conversational lookups. Prefer the sibling corpus-search endpoint if you need to retrieve specific source documents rather than a conversational answer.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-15T18:34:25.005Z","isFirstParty":false}
