What problem does it solve? Turning a vague feature idea or bug report into a well-structured, review-ready requirement document is slow and error-prone. This Skill controls the full req-define workflow of the AgentDevFlow plugin, guiding an AI agent through dialogue, existing-requirement matching, decision analysis, and draft generation so requirements are captured consistently and resumably. ## Core Features & Use Cases - 11-Step Workflow Control: Runs session-context detection, interactive requirement dialogue (HITL), existing REQ matching, requirement expansion, Decision judgment, draft-data generation, work_type/Scale classification, adversarial review, draft saving, and completion reporting. - Structured Draft Output: Produces .agentdev/drafts/req-draft-{topic-slug}.md in a structured draft-data YAML format containing operation_units, artifact_actions, test_strategy, and review_dispositions, consumed downstream by case-open, case-ready, and case-revise. - Resumable State Management: Persists agreed content into durable draft state so interrupted sessions resume from saved progress rather than conversation history. - Use Case: A developer describes a new feature in natural language; the Skill interviews them, checks existing REQ documents for APPEND/UPDATE candidates, derives boundary risks and a test strategy, runs an adversarial review, and saves a requirement draft ready for case-open. ## Quick Start Invoke the /agentdev/req-define command with a description of your feature or bug fix and let the workflow guide you through requirement definition.
