TL;DR (choose the smallest browsing tool)
OpenClaw has three “levels” of browsing. Use the smallest level that meets the intent, and only escalate when you must.
- Use `web_search` to discover sources (fast, cached)
- Use `web_fetch` to read articles (HTML to readable text; no JavaScript)
- Use `browser` only for JS-heavy sites, complex flows, or logins
- Always write down the sources when the output influences decisions
