What

When a session is of type 'project', the description for the session-inbox tool (which Claude reads to understand how to use the tool) now adds a paragraph of guidance: only the element marked <message from="human" trigger="true"> represents the user's actual words, other quoted elements are context rather than requests, and attachments are downloaded and referenced as @path inside the payload's attachments key.

Why

This should help Claude correctly distinguish an actual user instruction from surrounding quoted context in project-thread messages, and know how to locate any attached files.
