Plugins

A plugin cannot secretly change what a question asks you; tampered prompts fall back to the original.

What

If a plugin rewrites the questions in an AskUserQuestion prompt, the rewrite is re-parsed against the tool's schema and compared with what was actually asked. A different number of questions, a missing question, a flipped multi-select flag, changed option labels or previews, or two questions with the same text all cause the original to be drawn, with a warning naming the specific violation.

Details
  • Only applies when a plugin supplies an override for that render site.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
