Summary
In claude.ai/code, the @ picker that lets you reference another session only opens when @ is the first character of the message. Typed anywhere later in the message it does nothing, so there is no way to complete the mention in the middle of a sentence.
Steps to reproduce
- Open a session on claude.ai/code.
- Type
@as the first character of an empty composer — the picker of existing conversations opens, and choosing one inserts a mention like@"assembly task". - Now type any text first, e.g.
are you and, then@. Nothing opens; the@is just a literal character.
Expected
@ should open the picker anywhere it is a valid mention position — normally at the start of a word, i.e. after whitespace — which is how mention inputs usually behave.
Impact
Minor but constant: to mention a session inside a sentence you have to type the mention first while the composer is empty and then build the sentence around it.
Observed on claude.ai/code; I haven't checked whether the CLI or desktop clients behave the same way.
