Deep Research Skill

A 7-phase research system for Claude Code that produces decision-grade, auditable, hallucination-resistant research outputs.

What Makes This Different?

Installation

Option 1: Clone to Skills Directory

cd ~/.claude/skills
git clone https://github.com/YOUR_USERNAME/deep-research-skill.git deep-research

Option 2: Manual Installation

1. Download this repository as a ZIP
2. Extract to ~/.claude/skills/deep-research/
3. Restart Claude Code

Usage

Simply say: “Deep research [your topic]”

Examples:

• “Deep research the current state of quantum computing”
• “Deep research best practices for SaaS pricing”
• “Research AI regulation in Europe thoroughly”

Research Types

The system automatically classifies your question:

The 7 Phases

0. Classify    → What type of research is this?
1. Scope       → What exactly are we researching?
1.5 Hypothesize → What are the likely answers?
2. Plan        → How will we find information?
3. Query       → Execute parallel searches
4. Triangulate → Verify claims across sources
5. Synthesize  → Combine into coherent findings
6. QA          → Verify citations and claims
7. Package     → Deliver structured output

Output Structure

All research is saved to /RESEARCH/[topic_name]/:

RESEARCH/
└── [topic_name]/
    ├── README.md                    # Navigation guide
    ├── 00_research_contract.md      # Scope agreement
    ├── 01_research_plan.md          # Subquestions, queries
    ├── 02_query_log.csv             # All searches
    ├── 03_source_catalog.csv        # Sources with ratings
    ├── 04_evidence_ledger.csv       # Claims → Sources

    │   ├── 01_findings.md
    │   └── 02_recommendations.md
    └── 09_qa/
        └── qa_report.md

Key Principles

1. No claim without evidence - Mark unsourced claims as [Source needed]
2. 2-source rule - Critical claims need independent verification
3. Independence matters - 5 articles citing 1 report = 1 source
4. Contradictions are data - Document and explain, don’t hide
5. Track everything - Query logs, source catalogs, evidence ledgers

Domain Overlays

For specialized research, the system can load domain-specific requirements:

• Healthcare: PMID citations, FDA references, clinical trial registrations
• Financial: SEC filings, EDGAR links, audited sources
• Legal: Case citations, jurisdiction requirements
• Market: Market sizing methodology, competitive intelligence standards
