deep-research

AI-powered deep research with multi-agent source verification and structured outputs.

Turn a single question into a comprehensive, citation-backed research report — automatically.

Quick Start

1. Add the marketplace (once)

/plugin marketplace add https://github.com/fivetaku/gptaku_plugins.git

2. Install the plugin

/plugin install deep-research

3. Restart Claude Code

Cache loads on startup — a restart is required after install.

4. Start researching

/deep-research AI coding assistants productivity impact

Claude will ask a few scoping questions, then deploy parallel research agents and deliver a structured report.

Why deep-research?

• Parallel agents, not sequential searches — 3-5 agents run simultaneously across web, academic, and technical sources, cutting research time significantly
• Source quality ratings (A–E) — Every source is graded from peer-reviewed papers (A) to speculative posts (E), so you always know what you're reading
• Hallucination-resistant — Every factual claim requires an inline citation; key claims are cross-verified against at least 2 independent sources
• Resumable sessions — Research state is saved to state.json; pick up where you left off if a session is interrupted
• Complete deliverables — Executive summary, full sectioned report, bibliography, and an optional interactive website — all generated automatically

    ▼
Phase 1: Question Scoping
  └─ AskUserQuestion → focus, depth, audience, sources
    │
    ▼
Phase 2: Retrieval Planning
  └─ Break into 3-5 subtopics → search query generation → plan approval
    │
    ▼
Phase 3: Iterative Querying  ←──────────────────┐
  ├─ Web Research Agent (x2-3)                  │
  ├─ Academic/Technical Agent (x1-2)            │ refine if gaps

Phase 4: Source Triangulation ─────────────────-┘
  └─ Cross-verify key claims (≥2 sources) → A–E quality rating
    │

Phase 5: Knowledge Synthesis
  └─ Structure → write sections → inline citations

    ▼
Phase 6: Quality Assurance
  └─ Hallucination check → citation verification → completeness

    ▼
Phase 7: Output & Packaging
  └─ Executive summary + full report + bibliography + website (optional)

Agents

Three agent types run in parallel during Phase 3:

Agent	Count	Focus
Web Research	2–3	Latest news, trends, market data
Academic / Technical	1–2	Papers, specs, official docs
Cross-Reference	1	Fact-checking key claims

---

Source Quality Ratings

Grade	Type	Examples
A	Peer-reviewed, systematic reviews	Nature, Lancet, IEEE
B	Official docs, clinical guidelines	FDA, W3C, WHO
C	Expert opinion, industry reports	Gartner, conferences
D	Preprints, white papers	arXiv, company blogs
E	Anecdotal, speculative	Social media, forums
