Consider impact of Claude subagents

Problem/Motivation

Today (at the time of writing this) Claude released version 1.0.60, which has the following release notes:

Version 1.0.60:
    • You can now create custom subagents for specialized tasks! Run /agents to get started

Subagents is documented by Anthropic here: https://docs.anthropic.com/en/docs/claude-code/sub-agents

One of the reasons why I'm writing this up as an issue in the AI module is that I'm not sure where else to put this idea. You see, this allows us to create a "drupal-export" sub-agent that listens to the conversation happening between the user and the ai agent and decides which sets of problems could be handled by the agent.

These agent files need to follow a lose set of requirements. I've attempted to create the markdown file describing the agent. This file just needs to be placed in you ~/.claude/agents folder order to be loaded in your next claude session

Can you all take a look and figure out ways to improve it? Also would it be beneficial if I just posted the contents of this file verbatim for review?
