Feature: Cost reporting in plan status and session show CLI output
  As a user
  I want to see cost information in the plan status and session show commands
  So that I can track how much I've spent on plans and sessions

  Scenario: Plan status JSON output includes cost field
    Given a plan status CLI runner with mocked service
    And a plan exists with cost metadata
    When I run plan status --format json for the plan
    Then the JSON output contains a "cost" field
    And the cost field contains cost metadata

  Scenario: Session show JSON output includes estimated cost
    Given a session show CLI runner with mocked service
    And a session exists with token usage
    When I run session show --format json for the session
    Then the JSON output contains "estimated_cost" field
    And the estimated_cost is properly formatted as currency

  Scenario: Plan status rich output displays cost panel
    Given a plan status CLI runner with mocked service
    And a plan exists with cost metadata
    When I run plan status for the plan with cost reporting
    Then the output contains cost information
    And the cost information is properly formatted

  Scenario: Session show rich output displays cost information
    Given a session show CLI runner with mocked service
    And a session exists with token usage
    When I run session show for the session
    Then the output contains cost information
    And the cost information is properly formatted
