What problem does it solve? Jumping into code without a plan leads to scope creep, missed edge cases, and rework. This Skill enforces a disciplined pre-coding workflow covering requirements analysis, repository research, risk assessment, and estimation. ## Core Features & Use Cases - Structured Planning Process: A five-step flow from requirements analysis through repo research, option analysis, risk assessment, and plan creation. - Risk Analysis Templates: Categorized risk tables (technical, dependency, time, scope, integration) with probability/impact ratings and mitigation plans. - Implementation Plan Template: Ready-to-use Markdown template covering scope, file changes, dependencies, timeline, and test strategy, plus T-shirt size estimation guidelines. - Use Case: Before adding a new API endpoint to an existing codebase, use this Skill to inspect current architecture patterns, list clarifying questions, evaluate two design alternatives, and produce a reviewed implementation plan. ## Quick Start Ask the agent to create an implementation plan for your feature, including repo research, risk analysis, and effort estimation before writing any code.
