What problem does it solve? It provides a single declarative source for the AgentDevFlow development workflow, so every agentdev command resolves phase transitions, work_type classification, and scale assessment consistently instead of duplicating judgment logic. ## Core Features & Use Cases - Workflow Phase Definitions: Maps SSoT transitions (req_draft → Issue → PR → merged PR + closed Issue) across req-define, case-open, case-ready, case-run, and case-close. - work_type and Scale Classification: Classifies work as bugfix, maintenance, docs_chore, or feature, and promotes feature scale to large when signals like 10+ affected files or 30+ changes appear. - Structured Stage Handoff: Defines the structured_context serialization contract and source/projection reference resolution policy for passing context between workflow stages. - Use Case: When running /agentdev/case-open, the prepare STEP consults this skill to determine the work_type route and whether the feature requires a large-scale OU/child-Issue structure. ## Quick Start Ask the agent to determine the work_type and command route for a new requirement using the agentdev workflow lifecycle definitions.
