implementation-plan

description

Structured implementation planning skill that enhances Claude's plan mode with mandatory questioning, research, problem decomposition, goal-driven criteria-first planning, and multi-agent verification before any implementation begins. Use when the user asks to plan a task, create an implementation plan, think through an approach, or when Claude enters plan mode. Plans are goal-driven: for code tasks, every step follows TDD (tests specified before implementation); for non-code tasks, every step has observable acceptance criteria defined before the approach. Plans are held to Google/NASA- grade quality standards and must pass independent verification by 3+ specialized sub-agents (requirements traceability, technical rigor, security & threat analysis) before presentation. Handles any domain — software engineering, design, business, research, content — by adapting its questioning depth, research strategy, and plan detail to the task's complexity and type. Always explores the codebase for code tasks; uses web research for non-code tasks.

Implementation Plan

A navigable reference graph for creating thorough implementation plans. Enhances plan mode with mandatory questioning, research, context-efficient decomposition, and multi-agent verification to Google/NASA-grade quality standards.

Planning Process

Six-step process. Steps 0.5, 1–2, 4.5, and 5 are mandatory and must never be skipped:

0.5	Domain classification — classify the task first	references/planning-process/domain-classification.md
1	Clarification — mandatory questioning phase	references/planning-process/step-1-clarification.md
2	Research — codebase exploration or web research	references/planning-process/step-2-research.md
3	Decompose — recursive task breakdown	references/planning-process/step-3-decompose.md
4	Generate plan — create the structured plan with quality doctrine	references/planning-process/step-4-generate-plan.md
4.5	Multi-agent verification — independent sub-agents verify the plan	references/planning-process/step-4.5-verification.md

Goal-Driven Methodology

Criteria-first planning across all domains. For technical tasks: TDD. For non-technical tasks: acceptance-criteria-driven.
