Web Search Techniques & Coordination

Overview

This skill provides patterns for web searching using Gemini CLI coordination or Claude's built-in WebSearch tool. It enables finding current information beyond knowledge cutoffs through precise instruction crafting.

Context

User needs to find current information, verify facts, or research topics online. This skill is appropriate when:

• Searching for recent developments or current events
• Verifying claims or checking facts
• Researching technical topics with up-to-date information
• Finding domain-specific information from particular websites

Process

1. Analyze user's web search requirements
2. Craft precise instructions for Gemini CLI or WebSearch tool
3. Execute the search with appropriate constraints
4. Process and validate the returned results
5. Present information with proper source attribution
6. Verification: Confirm sources are current and reliable

Agent Coordination Model

This skill operates on a two-agent model:

Your Role (Calling Agent):

• Analyzes user's web search requirements
• Crafts precise instructions for Gemini CLI
• Executes gemini -p commands with properly formatted prompts
• Processes and presents Gemini CLI's responses to users

Gemini CLI (Web Research Agent):

• A general-purpose agent restricted to web research operations only
• Accesses current information beyond knowledge cutoffs when asked to do web search
• Formats responses with source citations when requested
• Returns structured results based on received instructions
• Does NOT edit files, write code, execute commands, or perform any non-research actions

Core Principle

You do NOT perform web searches directly. Instead, you act as an intelligent prompt coordinator that crafts optimal instructions for Gemini CLI to execute web searches effectively.

Scope Limitations

Gemini CLI has the following tools:

• Codebase Investigator Agent (codebase_investigator)
• Edit (replace)
• FindFiles (glob)
• GoogleSearch (google_web_search)
• ReadFile (read_file)
• ReadFolder (list_directory)
• SaveMemory (save_memory)
• SearchText (search_file_content)
• Shell (run_shell_command)
• WebFetch (web_fetch)
• WriteFile (write_file)
• WriteTodos (write_todos)

But in this skill, we want to restrict Gemini CLI to web research operations ONLY. When crafting instructions, always include this constraint:

IMPORTANT: You are restricted to web research ONLY. Do not edit files, write code, execute commands, or perform any actions other than web searching and information gathering. Return only research findings with proper citations.

This ensures Gemini CLI operates purely as a web research tool without attempting general-purpose coding or file manipulation tasks.

Execution Commands

Basic Command Structure

# Direct web search with crafted instruction
gemini -p "[CRAFTED_INSTRUCTION_FOR_TOPIC]"

# Pipe content to Gemini with analysis instruction
cat [FILE] | gemini -p "Analyze this content and do web search for [RESEARCH_TOPIC]"

JSON Output for Structured Data

# Get structured JSON response
gemini -p "[INSTRUCTION]" --output-format json | jq '.response'

# Extract sources from JSON response
gemini -p "[INSTRUCTION]" --output-format json | jq '.sources[]'

# Process streaming responses for long content
gemini -p "[COMPREHENSIVE_INSTRUCTION]" --output-format stream-json

Response Processing

Handling Gemini CLI Responses

After executing gemini -p, process the returned information:

For standard text responses:

• Extract main content and source citations
• Verify that sources are properly formatted with URLs
• Check for publication dates and source authority
• Present information in user-friendly format

For JSON responses:

# Extract main response content
gemini -p "[INSTRUCTION]" --output-format json | jq -r '.response'

# Extract structured sources
gemini -p "[INSTRUCTION]" --output-format json | jq '.sources[] | "\(.title): \(.url)"'

# Get metadata about search quality
gemini -p "[INSTRUCTION]" --output-format json | jq '.metadata'

Quality Validation Guidelines

When processing Gemini CLI responses, verify:

1. Source currency - Check if information reflects recent developments
2. Source reliability - Assess credibility of cited sources
3. Information completeness - Ensure user's question is fully addressed
4. Source accessibility - Verify URLs are accessible and relevant

Error Handling Strategies

If Gemini CLI returns inadequate results:

1. Refine the instruction with more specific requirements: Do web search for [TOPIC]. Focus on sources from 2024-2025, look for official documentation, and include specific examples and data points. IMPORTANT: You are restricted to web research ONLY. Do not edit files, write code, execute commands, or perform any actions other than web searching and information gathering. Return only research findings with proper citations.
2. Add domain constraints for better source quality: Search the web on site:official-docs.com OR site:reputable-news.com about [TOPIC]. Focus on recent coverage and expert analysis. IMPORTANT: You are restricted to web research ONLY. Do not edit files, write code, execute commands, or perform any actions other than web searching and information gathering. Return only research findings with proper citations.
3. Request specific source types: Do web research about [TOPIC]. Look for academic papers, industry reports, and government statistics from the past 12 months. IMPORTANT: You are restricted to web research ONLY. Do not edit files, write code, execute commands, or perform any actions other than web searching and information gathering. Return only research findings with proper citations.

• Validate source currency - check publication dates before presenting information
• Use domain constraints (site:) for authoritative sources in specific fields
• For technical searches, always request sources from 2024-2025
• Process JSON output when structured data is needed
• Refine instructions if initial results are inadequate
