Deep Research Skill

Enables automatic deep research mode when trigger phrases are detected in user prompts.

Overview

This skill provides a UserPromptSubmit hook that detects natural language cues indicating the user wants thorough, comprehensive research. When triggered, it injects instructions for Claude to use enhanced research capabilities.

When This Skill Activates

The hook automatically detects these trigger phrases (case-insensitive):

• "deep dive"
• "use your noodle"
• "pull out the stops"
• "dig deep"
• "really research"
• "thorough investigation"
• "comprehensive analysis"
• "leave no stone unturned"

What Deep Research Mode Does

When activated, Claude will:

1. Use WebSearch extensively - Ground responses with current information from the web
2. Spawn Explore agents - Thoroughly investigate the codebase with specialized agents
3. Think systematically - Work through the problem methodically before responding
4. Synthesize multiple sources - Combine findings from various sources into a cohesive answer
5. Provide citations - Include sources for web-based findings

Installation

Hook Configuration

Add to your .claude/settings.json:

{
  "hooks": {
    "UserPromptSubmit": [
      {
        "command": "~/.claude/skills/deep-research/scripts/detect-research-mode.sh"
      }
    ]
  }
}

Manual Setup

1. Copy the skill to your Claude skills directory:

   cp -r registry/skills/deep-research ~/.claude/skills/
   

2. Make the hook script executable:

   chmod +x ~/.claude/skills/deep-research/scripts/detect-research-mode.sh
   

3. Add the hook configuration above to your settings

Usage Examples

Automatic Activation

Simply use trigger phrases naturally in your prompts:

"I need to deep dive into how authentication works in this codebase"
"Use your noodle on this one - why is the build failing?"
"Let's pull out the stops and figure out the best caching strategy"

What Happens

When a trigger phrase is detected, you'll see output like:

Deep research mode: Use WebSearch for current info, spawn Explore agents for codebase investigation, think systematically, synthesize findings from multiple sources.

This instructs Claude to use enhanced research capabilities for your question.

Customization

Adding Trigger Phrases

Edit scripts/detect-research-mode.sh and add patterns to the grep regex:

if echo "$input" | grep -qiE "(your-phrase|another-phrase)"; then

Modifying Research Instructions

Edit the output message in the script to customize what research behaviors are triggered.
