Struct ToolFilterConfig 

pub struct ToolFilterConfig {
    pub enabled: bool,
    pub top_k: usize,
    pub always_on: Vec<String>,
    pub min_description_words: usize,
}

Dynamic tool schema filtering configuration (#2020).

When enabled, only a subset of tool definitions is sent to the LLM on each turn, selected by embedding similarity between the user query and tool descriptions.

Fields

enabled: bool

Enable dynamic tool schema filtering. Default: false (opt-in).

top_k: usize

Number of top-scoring filterable tools to include per turn. Set to 0 to include all filterable tools.

always_on: Vec<String>

Tool IDs that are never filtered out.

min_description_words: usize

MCP tools with fewer description words than this are auto-included.
