Multi-source research with citation tracking, evidence persistence, and structured report generation.
What is deep-research?
Deep Research delivers comprehensive, citation-tracked research reports through a structured 6-8 phase pipeline. Use it for complex analyses, technology comparisons, trend reviews, and multi-perspective investigations that require evidence persistence and claim-level verification—not for simple lookups or debugging.
- Executes multi-phase research workflows (quick, standard, deep, or ultradeep modes) with 3-45 minute timelines
- Maintains persistent evidence store with claim-level verification and source identity management
- Generates professional reports with Executive Summary, methodology, 4-8 cited findings, and complete bibliography
- Produces Markdown, HTML (McKinsey style), PDF, and structured JSON outputs (sources, evidence, claims registries)
- Triangulates claims across 3+ independent sources per major finding to ensure cluster-independent verification
- Surfaces high-materiality assumptions explicitly in Introduction and Methodology sections
How to install deep-research
npx skills add https://github.com/199-biotechnologies/claude-deep-research-skill --skill deep-research- Python installed for validation and conversion scripts (validate_report.py, verify_citations.py, md_to_html.py)
- Output directory access to ~/Documents/ for report generation
- Web search capability for multi-source retrieval
How to use deep-research
- 1.Invoke the skill with a research request (e.g., 'deep research on X', 'comprehensive analysis', 'compare X vs Y')
- 2.Select or confirm research mode: quick (3 phases, 2-5 min), standard (6 phases, 5-10 min), deep (8 phases, 10-20 min), or ultradeep (8+ phases, 20-45 min)
- 3.Allow the skill to execute the workflow: SCOPE → PLAN → RETRIEVE → TRIANGULATE → SYNTHESIZE → (CRITIQUE → REFINE if deep/ultradeep) → PACKAGE
- 4.Review generated outputs in ~/Documents/[Topic]_Research_[YYYYMMDD]/: Markdown report, HTML, PDF, and JSON evidence registries
- 5.Validate citations and claims using provided scripts (verify_citations.py, validate_report.py) if needed
Use cases
- Compare competing technologies or approaches with balanced perspective across multiple sources
- Analyze industry trends and state-of-the-art developments over recent 1-2 year periods
- Generate comprehensive market or competitive analysis reports with full citation tracking
- Investigate complex topics requiring multi-perspective synthesis and evidence-backed recommendations
- Create decision-support documentation for critical business or technical decisions
- Researchers and analysts requiring comprehensive, cited reports
- Product managers evaluating technology options or market trends
- Decision-makers needing evidence-backed analysis for critical choices
- Technical teams conducting state-of-the-art reviews
- Anyone producing documentation that requires full source attribution and claim verification
deep-research FAQ
Use Deep Research for complex analyses, comparisons, trend reviews, and multi-perspective investigations requiring 10+ sources and claim-level verification. Use simple search for quick lookups, debugging, or questions answerable in 1-2 searches.
Triangulation requires 3+ independent, cluster-diverse sources per major claim to verify findings. This ensures conclusions are not dependent on a single source perspective.
Yes. Choose from four modes: quick (2-5 min, 3 phases), standard (5-10 min, 6 phases), deep (10-20 min, 8 phases), or ultradeep (20-45 min, 8+ phases). Default is standard.
Markdown (primary source of truth), HTML (McKinsey style, auto-opened), PDF (professional print, auto-opened), and JSON registries (sources.jsonl, evidence.jsonl, claims.jsonl, run_manifest.json).
High-materiality assumptions are surfaced explicitly in the Introduction and Methodology sections rather than silently defaulted. The skill infers context-appropriate defaults (e.g., technical query = technical audience, comparison = balanced perspective, trend = recent 1-2 years).

Deep Research
Core Purpose
Deliver citation-tracked research reports through a structured pipeline with evidence persistence, source identity management, claim-level verification, and progressive context management.
Autonomy Principle: Operate independently. Infer assumptions from context. Only stop for critical errors or incomprehensible queries. Surface high-materiality assumptions explicitly in the Introduction and Methodology rather than silently defaulting.
Decision Tree
Request Analysis
+-- Simple lookup? --> STOP: Use WebSearch
+-- Debugging? --> STOP: Use standard tools
+-- Complex analysis needed? --> CONTINUE
Mode Selection
+-- Initial exploration --> quick (3 phases, 2-5 min)
+-- Standard research --> standard (6 phases, 5-10 min) [DEFAULT]
+-- Critical decision --> deep (8 phases, 10-20 min)
+-- Comprehensive review --> ultradeep (8+ phases, 20-45 min)
Default assumptions: Technical query = technical audience. Comparison = balanced perspective. Trend = recent 1-2 years.
Workflow Overview
| Phase | Name | Quick | Std | Deep | Ultra |
|---|---|---|---|---|---|
| 1 | SCOPE | Y | Y | Y | Y |
| 2 | PLAN | - | Y | Y | Y |
| 3 | RETRIEVE | Y | Y | Y | Y |
| 4 | TRIANGULATE | - | Y | Y | Y |
| 4.5 | OUTLINE REFINEMENT | - | Y | Y | Y |
| 5 | SYNTHESIZE | - | Y | Y | Y |
| 6 | CRITIQUE | - | - | Y | Y |
| 7 | REFINE | - | - | Y | Y |
| 8 | PACKAGE | Y | Y | Y | Y |
Note: Phases 3-5 operate as an evidence loop per section (retrieve → evidence store → refine outline → draft → verify claims → delta-retrieve if needed), not as strict sequential gates.
Execution
On invocation, load relevant reference files:
- Phase 1-7: Load methodology.md for detailed phase instructions
- Phase 8 (Report): Load report-assembly.md for progressive generation
- HTML/PDF output: Load html-generation.md
- Quality checks: Load quality-gates.md
- Long reports (>18K words): Load continuation.md
Templates:
- Report structure: report_template.md
- HTML styling: mckinsey_report_template.html
Scripts:
python scripts/validate_report.py --report [path]python scripts/verify_citations.py --report [path]python scripts/md_to_html.py [markdown_path]
Output Contract
Required sections:

- Main Analysis (4-8 findings, 600-2,000 words each, cited)
- Synthesis & Insights (patterns, implications)
- Limitations & Caveats
- Recommendations
- Bibliography (COMPLETE - every citation, no placeholders)
- Methodology Appendix
Output files (all to ~/Documents/[Topic]_Research_[YYYYMMDD]/):
- Markdown (primary source of truth)
sources.jsonl— stable source registry with canonical IDsevidence.jsonl— append-only evidence store with quotes and locatorsclaims.jsonl— atomic claim ledger with support statusrun_manifest.json— query, mode, assumptions, provider config- HTML (McKinsey style, auto-opened)
- PDF (professional print, auto-opened)
Quality standards:
- 10+ sources, 3+ per major claim (cluster-independent, not just count)
- All factual claims cited immediately [N] with evidence backing in
evidence.jsonl - Claim-support verification mandatory: no unsupported factual claims pass delivery
- No placeholders, no fabricated citations
- Prose-first (>=80%), bullets sparingly
When to Use / NOT Use
Use: Comprehensive analysis, technology comparisons, state-of-the-art reviews, multi-perspective investigation, market analysis.
Do NOT use: Simple lookups, debugging, 1-2 search answers, quick time-sensitive queries.
