Orchestrate end-to-end feature development from requirements to production deployment: [Extended thinking: This workflow orchestrates specialized agents through comprehensive feature development phases - from discovery and planning through implementation, testing, and deployment. Each phase builds on previous outputs, ensuring coherent feature delivery. The workflow supports multiple development methodologies (traditional, TDD/BDD, DDD), feature complexity levels, and modern deployment strategies including feature flags, gradual rollouts, and observability-first development. Agents receive detailed context from previous phases to maintain consistency and quality throughout the development lifecycle.] ## Use this skill when - Coordinating end-to-end feature delivery across backend, frontend, and data - Managing requirements, architecture, implementation, testing, and rollout - Planning multi-service changes with deployment and monitoring needs - Aligning teams on scope, risks, and success metrics ## Do not use this skill when - The task is a small, isolated backend change or bug fix - You only need a single specialist task, not a full workflow - There is no deployment or cross-team coordination involved ## Instructions 1. Confirm feature scope, success metrics, and constraints. 2. Select a methodology and define phase outputs. 3. Orchestrate implementation, testing, and security validation. 4. Prepare rollout, monitoring, and documentation plans. ## Safety - Avoid pro...
