Missing 'action' parameter

Error message

Missing 'action' parameter

What it means

Guard in the composio tool's argument dispatch: the 'action' argument is missing (or not a recognized string), so the tool cannot decide between list/connect/execute. Unknown or missing action deliberately routes to the write path and requires an explicit value.

Solutions

1. Pass action as one of "list", "connect", or "execute"
2. Use the dedicated composio tools for each action instead of relying on the generic action switch
