Problem Statement

Feature request: expose a rename_session tool to Claude in Code Cloud / Desktop

Currently the assistant cannot rename the session it's running in. The only
session-affecting tool exposed is mark_chapter, which adds a divider in
the timeline but doesn't change the title shown at the top of the page.

This blocks integrations where an external system (e.g. an internal ticket
tracker, CRM, project tool) wants to feed Claude a context prompt and have
the session adopt a deterministic name like #1007 Issue title for later
retrieval.

Workaround today: the prompt asks Claude to call mark_chapter with the
desired name, then asks the user to manually click the session title and
type it in. This works but adds a step for every session.

Proposed:

A tool rename_session(name: string) available to Claude in Code Cloud
(and ideally Desktop), that updates the session's display title.

Use cases:

• Ticket tracker → "open Claude session for ticket #1007" button copies

a prompt; pasted prompt makes the session self-name

• CRM → similar (lead/account ID)
• PM tool → similar (issue key)

Why now: integrations like the above are easy to build with
navigator.clipboard.writeText() from any web app, but the rename step
is the only thing that breaks the loop. Adding the tool unblocks the
whole pattern with zero infra on either side.

Thanks!
