deep-research — Disciplined Meta-Research
The heavyweight end of the research domain: an auditable, reusable, triangulated investigation — for when a wrong answer costs more than the tokens spent getting it right.
deep-research is the rigor-first alternative to the fast research router. Where the router does keyword-classify → delegate → short brief for low-decision-risk questions, deep-research pays for rigor: falsifiable hypotheses, parallel sub-agent fan-out, source triangulation, a mandatory adversarial pass, and per-source files with verbatim quotes.
The 9-phase pipeline
| # | Phase | What it does |
|---|---|---|
| 1 | Reframe | Fix the underlying decision; state 2-4 falsifiable hypotheses |
| 2 | Genre & blocks | Pick report genre + building blocks |
| 3 | Plan | plan.md: scope, sourcing strategy, opposition queries, risk register, stop-criteria |
| 3.5 | Capability discovery | Audit available API keys/channels; map subtopics to sources |
| 4 | Search (parallel) | Fan out sub-agents → fetch & dedup → save each to sources/NN.md |
| 5 | Score & triangulate | Rate Credibility/Recency/Bias; require >=3 independent, differently-typed sources per thesis |
| 6 | Synthesize + adversarial | Assemble from blocks; 4 self-critique questions; steel-man counter-arguments |
| 6.5 | Verify | Lightweight citation check |
| 7 | Refresh targets | Emit refresh_targets.md for delta-updates |
Core discipline
- No fabricated citations — empty fetch = empty claim; every assertion binds to a saved verbatim quote.
- Triangulation mandatory — a thesis with < 3 independent, differently-typed sources is "insufficient evidence," not fact.
- Adversarial pass required on medium/deep investigations.
- Persist to files — output is a reusable folder, not a chat wall.
Use / don't use
Use for: strategy, comparing N options, hypothesis validation, mapping a field.
Not for: quick fact-checks (answer directly), 12-dimension competitor scoring (competitive-teardown), or fast low-risk overviews (the research router).
