Question

cosh_tools::question

Struct Question 

Source 
pub struct Question {
    pub description_ask: ToolDescription,
}
Expand description

Tool for asking structured questions to the user.

Use the ask method to present questions and collect answers. The tool is stateless — the TUI layer is responsible for showing the dialog and capturing user input.

Fields§

§description_ask: ToolDescription

MCP Tool description for ask_questions.

Implementations§

Source§

impl Question

Source

pub fn new() -> Self

Create a new Question with the tool description pre-configured.

Source

pub fn ask(&self, input: &QuestionInput) -> Result<QuestionOutput, String>

Present questions to the user and collect their answers.

Returns the user’s answers as a structured QuestionOutput. The TUI layer intercepts the tool call, renders the dialog, captures user input, and returns it as the tool result.

Single-select questions are normalized: the recommended option (the option carrying a " (Recommended)" label suffix, per the market convention) is stripped, badged, and moved to the top.

§Errors

Validation only rejects what cannot be rendered sensibly:

  • The questions array is empty.
  • A choice question has zero options.
  • A single-select option collides with the reserved types::CUSTOM_RESPONSE_LABEL (the TUI renders that label as its own virtual row, so such an option would be unreachable).

Everything else is normalized: empty options on a free-text question are cleared, and a types::RECOMMENDED_SUFFIX label naming an option that no longer exists is dropped.

Source

pub fn validate_and_normalize( input: &QuestionInput, ) -> Result<Vec<QuestionItem>, String>

Validate input and return the normalized questions.

Normalization: derive the per-question kind and stable ids, strip types::RECOMMENDED_SUFFIX labels into the internal recommended badge, clear empty option lists on free-text questions, drop recommendations that name no option, and move the recommended single-select option to position 0. Shared by Self::ask and the harness agent loop so both paths see identical validation and ordering.

§Errors

Same error contract as Self::ask.
