What's Wrong?

The /plugin-dev:agent-creator generated the content but the files weren't actually written.

What Should Happen?

The /plugin-dev:agent-creator generates the content and writes the files to disk.

Error Messages/Logs

I see the issue - the agent-creator generated the content but the files weren't actually written.
  Let me write them now using the Write tool. I'll extract the content from the agent-creator's
  output and create the files:

⏺ Write(agents/bootstrap-component-generator.md)
  ⎿  Wrote 152 lines to agents/bootstrap-component-generator.md

Steps to Reproduce

Use the /plugin-dev:create-plugin command, get to the point in the routine where it runs /plugin-dev:agent-creator.
