What problem does it solve? Ambiguous engineering work often leads to risky, hard-to-review changes and plans that fall apart when a different person or agent implements them. This Skill turns vague development tasks into concrete, self-contained implementation plans with explicit scope, sequencing, validation, and amendment rules. ## Core Features & Use Cases - Structured Planning Workflow: Guides scope definition, change-surface analysis, success criteria, and low-risk increment slicing for features, refactors, migrations, and bug fixes. - Anti-Ambiguity Rules: Forces explicit decisions on naming, contracts, failure behavior, and ownership so a fresh implementer can execute without chat history. - Specialized Checklists: Loads reference guides for stateful systems, human maintainability, review alignment, and plan amendments when relevant. - Use Case: You need to migrate a background job queue to a new persistence layer. The Skill produces an ordered plan covering state ownership, retry and recovery behavior, validation steps, and explicit stop conditions if the codebase contradicts the plan. ## Quick Start Use the development-task-planner skill to turn this feature request into a step-by-step implementation plan with risks, validation, and amendment triggers.
