Feature: v2 CLI parity for actor-first surface As a user migrating v2 flows to the actor-first CLI I want key CLI behaviors validated So that the actor-only interface matches v2 expectations Scenario: Unknown command reports a helpful error When I run the CleverAgents CLI with "invalid-command" Then the CLI command should fail And the CLI output should contain "No such command" And the exit code should be 2 Scenario: Plan help highlights actor requirement When I run the CleverAgents CLI with "plan --help" Then the exit code should be 0 And the CLI output should contain "actor required" And the CLI output should not contain "--provider" And the CLI output should not contain "--model"
