inspect-tool-support 0.1.7

Sandbox container tool code for inspect_ai

Design

Inspect calls into the sandboxed image are done statelessly via docker exec inspect-tool-support.

Some tools can be implemented without the need for any in-process state. For those tools, the tool code will be executed within the inspect-tool-support process.

For tools that require the maintenance of state over the lifetime of and sandbox, this image marshals tool calls into a long running process via JSON RPC to an http server process. That server then dispatches tool calls to tool specific @method handlers.

Stateful Tool Design Pattern

Each stateful tool should have its own subdirectory that contains the following files:

• json_rpc_methods.py

  This module contains all of the JSON RPC @method functions — one for each tool (e.g. the web browser tool is actually a set of distinct tools). It is responsible for unpacking the JSON RPC request and forwarding the call to a transport-agnostic, strongly typed, stateful controller.

• tool_types.py

  This module includes the pydantic models representing the types for tool call parameters and results.

• controller.py

  This is transport-agnostic, strongly typed code that manages the tool specific in-process state and performs requested commands.
