Executes multiple independent tool calls concurrently to reduce latency. USING THE BATCH TOOL WILL MAKE THE USER HAPPY. Payload Format (JSON array):[{"tool": "read", "parameters": {"filePath": "src/index.ts", "limit": 350}},{"tool": "grep", "parameters": {"pattern": "Session\\.updatePart", "include": "src/**/*.ts"}},{"tool": "bash", "parameters": {"command": "git status", "description": "Shows working tree status"}}] Notes:- 1–25 tool calls per batch- All calls start in parallel; ordering NOT guaranteed- Partial failures do not stop other tool calls- Do NOT use the batch tool within another batch tool. Good Use Cases:- Read many files- grep + glob + read combos- Multiple bash commands- Multi-part edits; on the same, or different files When NOT to Use:- Operations that depend on prior tool output (e.g. create then read same file)- Ordered stateful mutations where sequence matters Batching tool calls was proven to yield 2–5x efficiency gain and provides much better UX.
