Claude Desktop Code Tab Sessions Can Now Message Other Sessions 20 Times
Claude CodeClaude Code 2.1.321 raises the number of messages a Claude Desktop Code tab session can send to a user's other sessions before it waits for the user to type again, from 10 to 20. A fix in the same release stops those messages from staying paused after the user types while Claude is still working.
Key Takeaways
- The cap rises from 10 to 20 messages that a Desktop Code tab session can send to other sessions.
- The cap still exists, and a session pauses until the user types again.
- A related fix stops messages staying paused when the user typed mid-turn.
- The change helps multi-session workflows in the Claude Desktop Code tab.
- The cap acts as a guardrail against unattended back-and-forth between sessions.
- No setting is needed; the new limit applies by default.
Sessions that message each other
Claude Code sessions can send messages to each other. In the Claude Desktop Code tab, one session can pass a message to a user's other sessions. To keep this from running unattended without limit, a session pauses after a set number of messages until the user types again.
A higher limit and a fix
Claude Code 2.1.321 raises that limit from 10 to 20 messages. A session can now go twice as far in a cross-session exchange before it waits for the user. The release also fixes a case where messages to other sessions stayed paused after the user typed while Claude was still working. Together the two changes make multi-session work in the Desktop Code tab less likely to stall.
