Execute Batch
[data] 【複数ツール連続の前に検討】tools:[{id,tool,args}] で MCP ツールを最大10件順次実行。{{stepId.field}} で前ステップ結果を参照。関連ツール3〜5本を個別呼び出しすると往復3〜5回+ツール呼び出しオーバーヘッドが重複するが、execute_batch で1回にまとめコンテキスト消費を大幅削減(概算)。Examples: (1) 今日の日時→祝日→為替 tools:[{id:now,tool:datetime.get_current_datetime,args:{timezone:Asia/Tokyo}},{id:holiday,tool:datetime.is_holiday,args:{country:JP,date:{{now.date}}}},{id:rate,tool:network.get_exchange_rate,args:{from:USD,to:JPY}}] (2) JSON検証→マージ→統計 tools:[validate:data.validate_json,merge:data.merge_json,stats:data.calc_stats] (3) スラッグ→Base64→HMAC tools:[slug:text.generate_slug,b64:convert.base64,hmac:security.generate_hmac]。詳細は tool-catalog の execute_batch_presets 参照 / Prefer before chaining MCP tools: run up to 10 tools via tools:[{id,tool,args}] with {{stepId.field}} refs. Calling 3-5 related tools individually costs ~3-5 round trips plus repeated tool-call overhead; execute_batch combines them into one call, cutting context usage significantly (approx.). Ex1 today→holiday→rate: tools:[{id:now,tool:datetime.get_current_datetime,args:{timezone:Asia/Tokyo}},{id:holiday,tool:datetime.is_holiday,args:{country:JP,date:{{now.date}}}},{id:rate,tool:network.get_exchange_rate,args:{from:USD,to:JPY}}].
