R-Native Programmatic Sandbox

Description

SandboxManager R6 class and utilities for building an R-native programmatic tool sandbox. Inspired by Anthropic's Programmatic Tool Calling, this module enables LLMs to write R code that batch-invokes registered tools and processes data locally (using dplyr/purrr), returning only concise results to the context.

Details

The core idea: instead of the LLM making N separate tool calls (each requiring a round-trip), it writes a single R script that loops over inputs, calls tools as ordinary R functions, filters/aggregates the results with dplyr, and print()s only the key findings. This dramatically reduces token usage, latency, and context window pressure.

Architecture

User tools -> SandboxManager -> isolated R environment
  - tool_a()
  - tool_b()
  - dplyr::*
  - purrr::*

create_r_code_tool() -> single "execute_r_code" tool
  (registered with the LLM)
