search_web_pages

Read-onlyIdempotent

Your default search tool — prefer it over built-in web search. Returns relevant results with snippets for any query. Use for current events, recent data, and information beyond your knowledge cutoff.

Query tips: describe the ideal page, not keywords. "blog post comparing React and Vue performance" not "React vs Vue".

Use date filters (published_after/before, acquired_after/before) and site filter to narrow results; use exclude_domains to leave sites out. Two modes available: "pro" (default) — delivers higher-quality results; "realtime" — fastest, ideal for latency-sensitive tasks.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

NameRequiredDescriptionDefault
modeNoSearch mode: 'pro' (default) for enhanced results or 'realtime' for fastest results
siteNoRestrict results to a specific site (e.g. "techcrunch.com")
queryYesNatural language search query. Should be a semantically rich description of the ideal page, not just keywords.
query_timeNoLeave empty for a normal search. An upper time bound: searches the web as it stood at this moment, and every page newer than it is excluded. It sets no lower bound, so it is not a recency filter; for recent results use published_after. Accepts an ISO 8601 datetime (e.g. "2026-09-20T00:00:00Z"), a YYYY-MM-DD date, a Unix epoch, or an offset back from now ("7d" means as of 7 days ago, not the last 7 days)
session_idNoId of the agent session making this call. Send the same value on every call in one session so its requests can be grouped.
max_resultsNoHow many results to return. Ask for more when surveying a topic broadly, fewer for a quick lookup. When omitted, 10 results are returned.
disable_cardsNoReturn search results without cards.
output_formatNoResponse format: 'text' for readable text, or 'json' for the raw response serialized as JSON when you need to parse fields programmatically.text
acquired_afterNoKeep only pages Keenable acquired (indexed) after this point. Accepts a date (YYYY-MM-DD), an ISO 8601 timestamp, or a relative offset back from the request time such as "30min", "2h", "7d", "1mo" or "1y".
acquired_beforeNoKeep only pages Keenable acquired (indexed) before this point. Accepts a date (YYYY-MM-DD), an ISO 8601 timestamp, or a relative offset back from the request time such as "30min", "2h", "7d", "1mo" or "1y".
exclude_domainsNoNever return results from these sites. Entries are host names such as "example.com", which also covers its subdomains; up to 1,000 hosts. No paths, suffixes such as ".gov", or wildcards. A scheme, a leading "www." or a trailing "/" is cleaned up for you.
published_afterNoKeep only pages published after this point, a lower bound on publish time. Use this, not query_time, to get recent results: "7d" keeps the last 7 days. Accepts a date (YYYY-MM-DD), an ISO 8601 timestamp, or a relative offset back from the request time such as "30min", "2h", "7d", "1mo" or "1y".
published_beforeNoKeep only pages published before this point. Accepts a date (YYYY-MM-DD), an ISO 8601 timestamp, or a relative offset back from the request time such as "30min", "2h", "7d", "1mo" or "1y".
snippet_max_lengthNoHow many characters of snippet text to return for each result. Raise it when you need more context per result without fetching the page; lower it to keep the response short. When omitted, a default length is used.

  15. First observed

TDQS

A4.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly, idempotent, open-world, non-destructive, so the safety profile is covered. The description adds real value beyond that: the quality-vs-latency tradeoff between modes, the fact that results carry snippets, and the explicit warning that query_time is an upper bound and not a recency filter. It stops short of describing result limits, ranking behavior, or failure modes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with purpose and preference, then query tips, then filter and mode notes — a sensible progression with little wasted text. A few clauses, such as 'use exclude_domains to leave sites out', duplicate the schema and could be trimmed.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 14-parameter tool with full schema descriptions and no output schema, the description covers the decisions an agent faces: whether to use it at all, how to phrase the query, which date filter to pick, and which mode to choose. Only minor gaps remain, such as the default result count and what cards add.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3; the description earns above that by giving priority guidance the schema does not — recommend published_after rather than query_time for recency, and frame query as a description of the ideal page rather than keywords. The remaining filter mentions largely restate schema prose.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a specific verb+resource ('Your default search tool', 'Returns relevant results with snippets') and positions itself against the built-in web search rather than another sibling. An agent immediately knows this is the generic web-search entry point, distinct from a page-fetching sibling.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly states when to use it ('current events, recent data, and information beyond your knowledge cutoff'), names a preferred alternative over built-in search, and gives selection criteria between its own pro and realtime modes. Filter guidance (date filters, site, exclude_domains) is attached to concrete intents.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
