Direct answer: It looks like you’re hitting a Claude usage or context limit, which blocks new messages until the limit resets.
Here are practical steps you can take right away:
- Start a fresh conversation. The context window resets, letting you send new messages without carrying over the long thread.
- Check your plan’s limits. If you’re on a free tier, limits reset on a fixed cycle (often every few hours). Upgrading to a Pro tier can substantially increase those limits.
- Shorten inputs. If possible, break long inputs into smaller chunks and send them in multiple messages across separate conversations.
- Clear or minimize history in the current chat. Deleting old messages can sometimes help, but note that some platforms require starting a new chat to truly reset the context window.
- If you’re repeatedly hitting limits, save your work outside Claude (local notes or a document) and paste in smaller portions as needed.
If you want, tell me your current plan and roughly how you’re using Claude (volume per hour, typical message lengths, and whether you’re using Claude Pro). I can tailor a strategy to stay within limits and maximize throughput.
