Struct WorkbookToolHandler 

pub struct WorkbookToolHandler { /* private fields */ }

One served MCP tool per output Table (WBV2-04): validate → seed via cell_map → re-run the embedded IR → project ONLY this tool’s outputs (finite) → stamp.

Each handler advertises a per-tool I/O schema: an inputSchema carrying ONLY this tool’s DAG-derived input_keys, and a non-empty outputSchema over this tool’s own outputs (TypedToolWithOutput). The generic single calculate is retired (§4 — an LLM selects a NAMED tool per output Table).

Implementations

impl WorkbookToolHandler

pub fn new(bundle: Arc<WorkbookBundle>, tool: Tool) -> Self

Build over the shared verified bundle + this tool’s projection.

pub fn registered_name(&self) -> Result<String, WorkbookToolError>

The sanitized MCP tool name (the registered name + the metadata name — ONE source so they cannot drift).

Errors

Returns Err if this tool’s raw name is unmappable to the MCP charset.
