rho.coding

rho.coding supplies coding tools with explicit execution semantics: file operations, Bash with a typed cross-platform resolution, isolated R evaluation in mirai, and opt-in evaluation in a caller-supplied current-session environment.

Isolated R evaluation

library(rho.async)
library(rho.ai)
library(rho.coding)

r_tool <- rho_tool_r()
result <- rho_execute_tool(
  r_tool,
  ToolCall(
    id = "readme-r-1",
    name = "r",
    arguments = list(code = "sum((1:6)^2)")
  ),
  context = NULL
) |>
  rho_await(timeout = 10000)

list(
  value = result@details$value,
  may_overlap = S7::S7_inherits(r_tool@overlap, ToolMayOverlap)
)
#> $value
#> [1] 91
#>
#> $may_overlap
#> [1] TRUE

The ordinary R tool is isolated and may overlap with another call. A RhoCurrentSessionREvaluator instead receives an explicit environment and requires exclusive scheduling. RhoRExpression is also a RhoOperation, and the chosen evaluator is recorded in a RhoREvaluationBinding. A remote NNG evaluator therefore adds evaluator methods rather than another agent execution path. Bash follows the same discipline: on Windows it resolves a real Bash implementation rather than translating model-generated Bash into another shell language, and on Unix it reports a typed unavailable value when Bash is absent.
