Overview

# Deep Research Skill for Claude Code

A comprehensive research engine that brings Claude Desktop's Advanced Research capabilities (and more) to Claude Code terminal.

Features

Core Research Pipeline

  • 8.5-Phase Research Pipeline: Scope β†’ Plan β†’ Retrieve (Parallel) β†’ Triangulate β†’ Outline Refinement β†’ Synthesize β†’ Critique β†’ Refine β†’ Package
  • Multiple Research Modes: Quick, Standard, Deep, and UltraDeep
  • Graph-of-Thoughts Reasoning: Non-linear exploration with branching thought paths

2025 Enhancements (Latest - v2.2)

  • πŸ”„ Auto-Continuation System (NEW): TRUE UNLIMITED length (50K, 100K+ words) via recursive agent spawning with context preservation
  • πŸ“„ Progressive File Assembly: Section-by-section generation with quality safeguards
  • ⚑ Parallel Search Execution: 5-10 concurrent searches + parallel agents (3-5x faster Phase 3)
  • 🎯 First Finish Search (FFS) Pattern: Adaptive completion based on quality thresholds
  • πŸ” Enhanced Citation Validation (CiteGuard): Hallucination detection, URL verification, multi-source cross-checking
  • πŸ“‹ Dynamic Outline Evolution (WebWeaver): Adapt structure after Phase 4 based on evidence
  • πŸ”— Attribution Gradients UI: Interactive citation tooltips showing evidence chains in HTML reports
  • πŸ›‘οΈ Anti-Fatigue Enforcement: Prose-first quality checks prevent bullet-point degradation

Traditional Strengths

  • Citation Management: Automatic source tracking and bibliography generation
  • Source Credibility Assessment: Evaluates source quality and potential biases
  • Structured Reports: Professional markdown, HTML (McKinsey-style), and PDF outputs
  • Verification & Triangulation: Cross-references claims across multiple sources

Installation

The skill is already installed globally in ~/.claude/skills/deep-research/

No additional dependencies required for basic usage.

Usage

In Claude Code

Simply invoke the skill:

```

Use deep research to analyze the state of quantum computing in 2025

```

Or specify a mode:

```

Use deep research in ultradeep mode to compare PostgreSQL vs Supabase

```

Direct CLI Usage

```bash

# Standard research

python ~/.claude/skills/deep-research/research_engine.py --query "Your research question" --mode standard

# Deep research (all 8 phases)

python ~/.claude/skills/deep-research/research_engine.py --query "Your research question" --mode deep

# Quick research (3 phases only)

python ~/.claude/skills/deep-research/research_engine.py --query "Your research question" --mode quick

# Ultra-deep research (extended iterations)

python ~/.claude/skills/deep-research/research_engine.py --query "Your research question" --mode ultradeep

```

Research Modes

| Mode | Phases | Duration | Best For |

|------|--------|----------|----------|

| Quick | 3 phases | 2-5 min | Simple topics, initial exploration |

| Standard | 6 phases | 5-10 min | Most research questions |

| Deep | 8 phases | 10-20 min | Complex topics requiring thorough analysis |

| UltraDeep | 8+ phases | 20-45 min | Critical decisions, comprehensive reports |

Output

Research reports are saved to organized folders in ~/Documents/[Topic]_Research_[Date]/

Each report includes:

  • Executive Summary
  • Detailed Analysis with Citations
  • Synthesis & Insights
  • Limitations & Caveats
  • Recommendations
  • Full Bibliography
  • Methodology Appendix

Unlimited Report Generation (2025 Auto-Continuation System)

Reports use progressive file assembly with auto-continuation - achieving truly unlimited length through recursive agent spawning:

How It Works:

  1. Initial Generation (18K words)

- Generate sections 1-10 progressively

- Each section written to file immediately (stays under 32K limit per agent)

- Save continuation state with research context

  1. Auto-Continuation (if needed)

- Automatically spawns continuation agent via Task tool

- Continuation agent loads state: themes, narrative a
