Downloads pages by their links and returns the main text as markdown. Links are fetched in parallel; a single call handles up to 10 of them, so batch all links you need into one call instead of calling the tool per link.

Size: the 'max_chars' limit applies to each page separately, not to the whole response — 5 links stay under the limit each and the response holds all 5 texts. The limit counts characters, not tokens. A page cut short ends with '[truncated]' and its 'truncated' field is set; the cut-off part cannot be fetched afterwards, so treat what you got as all there is for that page.

Searches the web for one or more queries and returns snippets with links. Queries run in parallel. IMPORTANT: Always write search queries in English for best results and relevance. For images use the 'web_search_images' tool; both tools can be called in the same turn when a query needs text and images.

Freshness: set the 'date' field to restrict results by recency — 'd' (past day), 'w' (past week), 'm' (past month), 'y' (past year). Use it to prefer the most recent pages when the user asks about news or anything time-sensitive; leave it empty for all time.

Query operators (put them inside the query string itself): 'site:example.com term' limits the search to one site; 'filetype:pdf term' restricts to a file type; double quotes "exact phrase" force an exact match; a leading '-' excludes a word (term -foo); 'intitle:term' requires the word in the page title. Operators can be combined, e.g. 'site:arxiv.org filetype:pdf transformers'.

Searches for images by one or more queries, executed in parallel. IMPORTANT: Queries must be in English ONLY.

Freshness: set the 'date' field to restrict results by recency — 'd' (past day), 'w' (past week), 'm' (past month), 'y' (past year); leave it empty for all time.

Query operators can be embedded in the query string: 'site:example.com term' limits to one site, double quotes "exact phrase" force an exact match, and a leading '-' excludes a word.
