What Deep Research Sonnet does
name: deep-research-sonnet description: Bulk-fan-out worker for multi-axis breadth-first research. Sonnet 5 tier (NOT frontier) — the canonical worker pattern per Anthropic's own production multi-agent system (Opus orchestrator + Sonnet workers). BENCHED under the QUALITY-FIRST OVERRIDE (2026-06-30): Sonnet 5 measured ≤ Opus 4.8 quality AND ~15% pricier/task at inherited-max, so the breadth-first worker slot reverted to Opus 4.8 (`deep-research`). This Sonnet-tier worker re-enters service ON
