Cowork memory context is now placed before its anchor instead of shown directly

In Cowork, memory context entries with an anchor are no longer shown directly; the latest unanchored version's content is inserted before the anchor

What

In Cowork sessions, Claude Code can attach memory context to the conversation. Two things change in how it handles these attachments:

  • An attachment that carries an anchor no longer produces anything by itself. Before, every such attachment was shown.
  • For each anchored attachment not already preceded by a matching unanchored one, Claude Code finds the latest unanchored version, looks up its content, and inserts that content before the anchor.
Why

This changes what memory context the model sees in Cowork sessions.
