wtf

The user did not follow something. Explain it the way you would to a smart colleague who was not in the room.

Done: the user can say what the source means and what, if anything, they need to decide or do, without going back to the source.

What to explain

The text the user passed with the invocation decides the target:

• Nothing passed: your most recent message.
• A file path or a link: read it, then explain it.
• A pasted passage: that passage.
• A short pointer such as "the migration part" or "step 3": only that part of the conversation.

If the target is still unclear, ask one short question instead of guessing.
