Struct ToolInputMinimizer 

pub struct ToolInputMinimizer { /* private fields */ }

Strips sensitive or unnecessary content from tool call arguments.

Before a tool call is executed, the minimizer removes:

• System prompt fragments (e.g., “You are a …”, “Your instructions are …”)
• Prompt injection attempts embedded in tool arguments
• Excessive whitespace and padding
• PII (email, phone, SSN patterns) when configured
• Content exceeding the maximum input length

Implementations

impl ToolInputMinimizer

pub fn new() -> Self

Create a new minimizer with default patterns and settings.

Default maximum input length is 10,000 characters. PII stripping is enabled by default.

pub fn with_max_input_length(self, max: usize) -> Self

Set the maximum input length (in characters).

pub fn with_strip_pii(self, strip: bool) -> Self

Set whether PII should be stripped from tool inputs.

pub fn minimize( &self, input: &str, _tool_context: &ToolContext, ) -> MinimizeResult

Minimize tool input by stripping sensitive and unnecessary content.

Returns a MinimizeResult containing the cleaned text and metadata about what was removed.
