A drop-in replacement for Claude Code's built-in deep-research workflow that runs each
stage on the cheapest model that does the job well, instead of running everything on the
session model (Opus/Fable). Same pipeline — Scope → Search → Fetch → 3-vote adversarial
Verify → Synthesize — same cited report, a fraction of the cost.
| Stage | What it does | Model |
|---|---|---|
| Scope | Decompose the question into ~5 search angles | inherits session model |
