Struct WebSearchConfig 

pub struct WebSearchConfig {
    pub provider: WebSearchProvider,
    pub max_results: usize,
    pub timeout_secs: u64,
    pub cooldown_ms: u64,
    pub cache_ttl_secs: u64,
    pub session_max_requests: u32,
}

Web Search tool configuration.

VT Code only uses the keyless DuckDuckGo HTML endpoint. The defaults below are tuned to be polite to that endpoint and to keep the agent responsive under constrained network conditions:

• cooldown_ms: minimum gap between consecutive live requests on the same tool instance (avoids bursty hammering that triggers the DDG anti-bot challenge).
• cache_ttl_secs: how long successful results are served from memory before a fresh request is made.
• session_max_requests: hard cap on outbound requests per tool instance (defends against runaway loops).

Fields

provider: WebSearchProvider

Provider selection. The built-in backend is the keyless DuckDuckGo HTML endpoint; auto is retained as a compatibility alias.

max_results: usize

Default cap on the number of results returned per call. Hard-capped at 20 by the runtime to keep responses inline-friendly.

timeout_secs: u64

Per-request timeout in seconds. Capped at 60s by the runtime.

cooldown_ms: u64

Minimum gap between consecutive live requests, in milliseconds. Defaults to 3000ms (3s).

cache_ttl_secs: u64

How long successful search results are cached before a fresh request is made, in seconds. Defaults to 300s (5 min).

session_max_requests: u32

Hard cap on outbound network requests per tool instance. Defaults to 12 as a conservative VTCode budget; this is not a DuckDuckGo quota.
