Downloads pages by their links and returns the main text as markdown. Use this to read a page in full after 'web_search' found it; snippets alone are often not enough. Links are fetched in parallel, up to 10 per call, so batch all links into one call.

Size: 'max_chars' is a per-page character limit (not tokens). A page cut short ends with '[truncated]' and has 'truncated' set; the rest cannot be fetched afterwards.

Results are reported per URL with a 'status' field (success, failed or timeout). A failed URL does not fail the others; the call errors only if every URL fails. Target sites may block or rate-limit the request, which shows up as a failed URL.

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. Use this to find sources; then call 'web_scrape' to read a full page, or 'web_search_images' when you need pictures (both can be called in the same turn).

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'.

Results are reported per query with a 'status' field (success, failed or timeout). A failed query does not fail the others; the call errors only if every query fails. The upstream search engines may rate-limit or block requests, which shows up as a failed or timed-out query - retry later or rephrase.

Searches for images by one or more queries, executed in parallel. IMPORTANT: Queries must be in English ONLY. Use this only when you need pictures; use 'web_search' for text answers and links, and 'web_scrape' to read a page.

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.

Results are reported per query with a 'status' field (success, no relevant, failed or timeout). A failed query does not fail the others; the call errors only if every query fails. The upstream image search may rate-limit or block requests, which shows up as a failed or timed-out query.
