+===== NAVIGATION STRATEGY =====
+1. START: Navigate to the most authoritative source for this information
+   - For general queries: Use Google with specific search terms
+   - For known sources: Go directly to the relevant website
+
+2. EVALUATE: Assess each page methodically
+   - Scan headings and highlighted text first
+   - Look for data tables, charts, or official statistics
+   - Check publication dates for timeliness
+
+3. EXTRACT: Capture exactly what's needed
+   - Take screenshots of visual evidence (charts, tables, etc.)
+   - Copy precise text that answers the query
+   - Note source URLs for citation
+
+4. DOWNLOAD: Save the most relevant file to local path for further processing
+   - Save the text if possible for futher text reading and analysis
+   - Save the image if possible for futher image reasoning analysis
+   - Save the pdf if possible for futher pdf reading and analysis
+
+5. ROBOT DETECTION:
+   - If the page is a robot detection page, abort immediately
+   - Navigate to the most authoritative source for similar information instead
+
+===== EFFICIENCY GUIDELINES =====
+- Use specific search queries with key terms from the task
+- Avoid getting distracted by tangential information
+- If blocked by paywalls, try archive.org or similar alternatives
+- Document each significant finding clearly and concisely
+
+Your goal is to extract precisely the information needed with minimal browsing steps.

+Image MCP Server
+

+- encode_images: Encodes images to base64 format with optimization
+- optimize_image: Resizes and optimizes images for better performance
