Gemini Search Plugin
Advanced web search plugin using the Gemini CLI in headless mode with google_web_search tool restriction, providing caching, analytics, content extraction, and validation for Claude Code.
Important: This plugin uses the Gemini CLI with the google_web_search tool exclusively via headless mode (gemini -p with --yolo flag). It does NOT:
- Trigger Claude's internal web search functionality
- Use direct web scraping or crawling
- Bypass the Gemini CLI in any way
The plugin restricts the Gemini CLI to only use the google_web_search tool through the .gemini/settings.json configuration.
Features
💎 Key Features
- Gemini CLI Headless Mode - Uses
gemini -p with --yolo flag for automated web search
- Tool Restriction -
.gemini/settings.json limits Gemini to only google_web_search tool
- Grounded Results - All search results come from Google's web search via Gemini
- Subagent Architecture - Context isolation for 39% better token savings
- Smart Caching - 1-hour TTL with MD5 keying
- Auto-retry Logic - Exponential backoff on failures
- Dynamic Content Extraction - Extract and parse content from websites using Gemini
- False Positive Validation - Validate search results for relevance
- Comprehensive Logging - Detailed logging for debugging and monitoring
- 3 Slash Commands -
/search, /search-stats, /clear-cache
- 2 Hooks - Error detection and pre-edit suggestions
- Complete Analytics - Track usage and token savings
- Production Ready - Error handling, logging, validation
- No Web Scraping - Zero direct HTTP requests or HTML parsing
Commands
/search [query]
Perform a web search using multiple search engines with smart caching and result validation.
/search-stats
View usage statistics including cache hit rate, top queries, and token savings.
/clear-cache
Clear the search result cache and reset analytics data.

Advanced Features
Dynamic Content Extraction
- Extracts clean text content from web pages
- Removes HTML tags, scripts, and styling
- Validates content relevance to search query
- Handles multiple content sources with fallback methods
False Positive Validation
- Validates search results against original query
- Calculates relevance scores for each result
- Filters out irrelevant or low-quality content
- Provides warnings for potentially irrelevant results
Comprehensive Error Handling
- Retry logic with exponential backoff
- Multiple search engine fallbacks
- Network error handling and recovery
- Graceful degradation when services are unavailable
Logging System
- Detailed logging of search operations
- Error logging with context information
- Performance metrics tracking
- Audit trail for compliance and debugging
Getting Started
Prerequisites
-
Install Gemini CLI:
npm install -g @google/gemini-cli
-
Verify Installation:
gemini --version
-
Configure API Key (optional):
gemini config set apiKey YOUR_GOOGLE_AI_API_KEY
Usage
- Install the plugin in your Claude Code environment
- The
.gemini/settings.json file is automatically used to restrict tools
- Use
/search [your query] to perform web searches via Gemini
- Check
/search-stats to monitor usage and cache effectiveness
- Use
/clear-cache if you need to reset cached results
Configuration
The plugin can be configured through environment variables:
CACHE_TTL: Cache time-to-live in seconds (default: 3600)MAX_RETRIES: Number of retry attempts on failure (default: 3)RETRY_DELAY: Initial delay between retries in seconds (default: 1)BACKOFF_BASE: Exponential backoff base (default: 2)LOG_FILE: Path to main log file (default: /tmp/gemini-search.log)ERROR_LOG_FILE: Path to error log file (default: /tmp/gemini-search-errors.log)SUGGESTIONS_LIMIT: Number of suggestions to generate (default: 5)CONTEXT_WINDOW: Number of previous messages to consider (default: 10)TIMEOUT_SECONDS: Content extraction timeout (default: 15)MAX_CONTENT_SIZE: Maximum content size to process (default: 100000)
Performance Notes
- Results are cached for 1 hour to reduce API calls
- Context isolation helps save tokens by isolating search operations
- Cache hit rate is tracked to measure effectiveness
- Error handling with exponential backoff ensures reliability
- Content extraction is optimized to focus on relevant information
- Relevance validation prevents false positive results
Performance Metrics:
- Cached searches: <1 second (97% faster)
- First searches: 8-20 seconds
- Cache hit rate: 60-85% (typical usage)
- Memory usage: <50MB
- Token savings: 39% via context isolation
For detailed benchmarks and optimization strategies, see docs/PERFORMANCE.md
Examples:
Troubleshooting
- If searches fail, check the error logs at the configured LOG_FILE location
- Use
/search-stats to see if cache hit rate is improving performance
- If getting rate limited, consider extending the time between searches
- Use
/clear-cache if cached results seem outdated
- Check content extraction logs if web content isn't being parsed correctly
- Monitor validation warnings for potentially irrelevant results
Security Considerations
- Content extraction is limited to prevent processing oversized responses
- URLs are validated to prevent malicious inputs
- All external requests are made with appropriate timeouts
- Error messages don't expose sensitive system information
