Feature: LSP Tool Adapter uncovered-line coverage
  Exercise runtime-handler branches, workspace-symbols paths,
  missing-argument guards, and the None-config check in
  LspToolAdapter.generate_tool_specs (tool_adapter.py lines
  126-153 and 198).

  Scenario: ltacov generate_tool_specs raises ValueError when config is None
    Given ltacov an LspToolAdapter with no runtime
    When ltacov generate_tool_specs is called with None config
    Then ltacov a ValueError with message "config must not be None" is raised

  Scenario: ltacov workspace-symbols handler returns error when query is empty
    Given ltacov a mock LspRuntime
    And ltacov a runtime handler for workspace_symbols capability
    When ltacov the handler is called with no query argument
    Then ltacov the result is an error dict saying "query is required"

  Scenario: ltacov workspace-symbols handler raises LspNotAvailableError with valid query
    Given ltacov a mock LspRuntime
    And ltacov a runtime handler for workspace_symbols capability
    When ltacov the handler is called with query "MyClass"
    Then ltacov an LspNotAvailableError is raised mentioning "workspace_symbols"

  Scenario: ltacov runtime handler returns error when file_path is missing
    Given ltacov a mock LspRuntime
    And ltacov a runtime handler for diagnostics capability
    When ltacov the handler is called with no file_path argument
    Then ltacov the result is an error dict saying "file_path is required"

  Scenario: ltacov runtime handler delegates diagnostics to runtime
    Given ltacov a mock LspRuntime
    And ltacov the runtime get_diagnostics returns sample items
    And ltacov a runtime handler for diagnostics capability
    When ltacov the handler is called with file_path "src/main.py"
    Then ltacov the result contains a "diagnostics" key with the sample items

  Scenario: ltacov runtime handler delegates completions to runtime
    Given ltacov a mock LspRuntime
    And ltacov the runtime get_completions returns sample items
    And ltacov a runtime handler for completions capability
    When ltacov the handler is called with file_path "src/main.py" line 10 column 5
    Then ltacov the result contains a "completions" key with the sample items

  Scenario: ltacov runtime handler raises LspNotAvailableError for unimplemented capability
    Given ltacov a mock LspRuntime
    And ltacov a runtime handler for hover capability
    When ltacov the handler is called with file_path "src/main.py"
    Then ltacov an LspNotAvailableError is raised mentioning "hover"
