Missing 'action_name' (or 'tool_slug') for execute

Error message

Missing 'action_name' (or 'tool_slug') for execute

What it means

Execute-path guard: neither tool_slug nor action_name was supplied (or they were not strings), so there is no Composio action to execute. The security gate for composio.execute has already passed at this point.
