+We are building workflow automations. There are many blocks in a workflow. Generate a summary for the following block to help the user understand what the block is planning to do.

+{{ block }}

+Respond with the following JSON format:
+```
+{
+    "summary": str // Be concise and to the point. Summarize the block in one sentence with no more than 20 words. Use languages like "Will do something", "Planning to do something", "Going to do something" and replace the "do something" with the actual action the block is planning to do.
