[Feature] Allow agents/skills to suggest or update thread titles with status indicators

Feature Request

It would be useful for Claude to suggest or update the thread title during a conversation to reflect the current status of the work — similar to how tools like Linear or Notion use status labels on tasks

Use Case

When working on discrete tasks across multiple sessions, it's hard to distinguish open, completed, and abandoned threads without manually renaming them each time.

Proposed Behavior

• At the start of a session, Claude suggests a descriptive thread title (e.g. [fix] <thread description>)
• As the session progresses, Claude can suggest updating the title with a status prefix:
• 🔄 [comment] Localize SearchSuggestions labels — in progress
• ✅ [comment] Localize SearchSuggestions labels — completed
• 🚫 [comment] Localize SearchSuggestions labels — abandoned
• The user can accept or dismiss the suggestion

This could be implemented as a new tool (e.g. SuggestThreadTitle) that Claude can call at key moments in a conversation.
