/**
 * assertion-generation.skill.ts
 *
 * Generates an ordered list of compact flow steps with ready-to-use Playwright
 * assertion expressions for each element found on the page.
 *
 * This skill runs as part of the generate_test flow. It builds a CompactStep[]
 * array that covers the full user journey:
 *   - Navigation and page load verification
 *   - Popup/modal dismissal if needed
 *   - Navigation link visibility checks
 *   - Form field fill steps with value assertions
 *   - Button click steps with enabled/visible assertions
 *   - Table visibility checks
 *   - Final heading/state verification
 *
 * The resulting steps are then compressed by ContextCompressor and embedded
 * into the spec-generation prompt for Claude. Each assertion is a complete
 * expect() expression Claude can copy verbatim into the test.
 *
 * Role in the overall flow:
 *   SkillOrchestrator.autoExecute() → AssertionGenerationSkill.execute()
 *   → CompactStep[] → buildSpecPrompt() → Claude writes spec
