gt_wasm_cook_batch · Claude Flow MCP: Risk & Policy

WHAT IT DOES

What gt_wasm_cook_batch does on Claude Flow

AI agents invoke gt_wasm_cook_batch to trigger actions in Claude Flow. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why gt_wasm_cook_batch needs a policy

This tool runs WebAssembly (WASM) code to evaluate/execute multiple formulas in batch. Executing WASM constitutes code execution with potentially broad side effects depending on formula content. The batch nature amplifies blast radius.

From the tool's definition "Batch cook multiple formulas using WASM" — executes WASM (WebAssembly) code to process multiple formulas in batch
