Web Search

When to use

• User asks about recent events, releases, or news
• User asks "what's the latest on [topic]?"
• User needs documentation, blog posts, or tutorials
• User asks about something that may have changed after your training cutoff

Tools

WebSearch — broad discovery

Use for open-ended queries where you don't know the exact source:

• "latest PyTorch release features"
• "state of the art object detection 2026"
• "CUDA 13 breaking changes"

WebFetch — read a specific page

Use when you have a URL (from search results or from the user):

• Reading a specific blog post or documentation page
• Following up on a search result for more detail

Workflow

1. Search first with WebSearch using specific, targeted queries
   • Bad: "AI stuff" → Good: "diffusion model architecture improvements 2026"
   • If the first query is too broad, refine with more specific terms
2. Read the most relevant results with WebFetch to get details
3. Synthesize — don't just dump search results, answer the question
4. Cite sources — always include URLs so users can read the originals

Formatting for Slack

• Answer the question first, then provide supporting details
• Include source URLs inline: "According to source, ..."
• If multiple sources disagree, note the discrepancy
• Keep it concise — summarize rather than quoting paragraphs
• Distinguish between confirmed facts and preliminary/unverified information
