Feature: Load Context from File CLI Feature
  As a user of CleverAgents
  I want to load context from a JSON file via the CLI
  So that I can quickly restore a saved context state

  Background:
    Given I have a temporary test directory for contexts
    And I have a test configuration file

  Scenario: Load context transiently with run command
    Given I have a context JSON file with sample data
    When I run the CLI with --load-context pointing to the JSON file
    Then the command should execute successfully
    And the global context should be applied to the app
    And the context should not be persisted after the run

  Scenario: Load context into named context with run command
    Given I have a context JSON file with sample data
    And I have a target context name "test_import_context"
    When I run the CLI with both --load-context and --context flags
    Then the command should execute successfully
    And the JSON context should be imported into the named context
    And the named context should be persisted
    And changes during the run should be saved to the named context

  Scenario: Load context with interactive command
    Given I have a context JSON file with messages and global context
    When I start an interactive session with --load-context
    Then the interactive session should start successfully
    And the loaded context should be available in the session
    And the context should be transient (not persisted after exit)

  Scenario: Verify global context is applied from loaded file
    Given I have a context JSON file with specific global context values
    When I run the CLI with --load-context
    Then the application should have access to the global context values
    And the global context keys should be available during execution

  Scenario: Load context file that doesn't exist
    Given I specify a non-existent context file path
    When I try to run the CLI with --load-context
    Then the command should fail with an appropriate error
    And the error should indicate the file was not found

  Scenario: Load invalid JSON context file
    Given I have a malformed JSON context file
    When I try to run the CLI with --load-context
    Then the command should fail with a JSON parsing error

  Scenario: Load context replaces existing named context
    Given I have an existing named context "replace_test"
    And the existing context has different data
    And I have a new context JSON file
    When I run the CLI with --load-context and --context "replace_test"
    Then the named context should be replaced with the new data
    And the old data should no longer be present

  Scenario: Load context with messages and state
    Given I have a context JSON file with messages, state, and metadata
    When I run the CLI with --load-context and --context "full_context_test"
    Then all context components should be imported
    And the messages should be accessible
    And the state should be accessible
    And the metadata should be preserved

  Scenario: Transient load doesn't create context directory
    Given I have a context JSON file
    When I run the CLI with only --load-context (no --context)
    Then the command should complete successfully
    And no context directory should be created
    And changes should not persist after the run

  Scenario: Load context file matches export format
    Given I have an existing context "export_test"
    When I export the context to a file
    And I delete the original context
    And I load the exported file into a new context "import_test"
    Then the new context should match the original data
    And all fields should be preserved
