The Problem
Once in a while, you will encounter an error like the following, which blocks you from further conversation with Claude Code.
claude block must have a corresponding `tool_use` block in the previous message
The Fix
You have several options:
-
End the current conversation and start a new one.
-
If you want to keep the current context, you can use the /compact command to wipe the conversation history while maintaining a summarised context.
/compact -
If you want to save time and tokens, you can use the /rewind command and go backward 1 to 2 steps.
/rewind
About rewind
-
If you proceed with the
rewind, you will see a list of your previous steps (checkpoints). You can pick one from the list.
-
You can also decide to restore just the conversation, just the code, or both.
-
Once restored, the problematic conversation (usually the last one) would be wiped. You can continue from the previous step.
