A powerful new tool that allows executing multiple tools in a single request for improved performance:

  • Tool Name: BatchTool (displayed as "Call" to users)
  • Purpose: Run multiple independent tool operations at once to reduce context usage and latency
  • Execution: Tools are executed in parallel when possible, otherwise serially
  • Usage Example:
  claude> /call
  {
    "invocations": [
      {
        "tool_name": "Bash",
        "input": {
          "command": "git blame src/foo.ts"
        }
      },
      {
        "tool_name": "Glob", 
        "input": {
          "pattern": "**/*.ts"
        }
      },
      {
