SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manual project planning is time-consuming, prone to oversight, and often lacks multi-perspective validation. This Skill automates the creation of detailed, validated project plans, ensuring clarity and adherence to standards.

Core Features & Use Cases

  • Method Clarity Assessment: Automatically judges if your project idea has a clear implementation method, guiding you to refine it if needed.
  • Four-Path Adaptive Workflow: Adapts planning based on whether your method is clear or unclear, and if you prefer interactive or fully automated execution.
  • Multi-Model Validation (Automated Mode): For unclear methods in automation mode, it uses an AI chain (Gemini, Codex, GPT-5) to enrich and validate the implementation approach.
  • Structured Plan Generation: Produces a comprehensive plan.md with milestones, tasks, dependencies (Mermaid diagrams), risks, and standards compliance.
  • Use Case: Ask Claude "Develop a user authentication feature." The plan-down skill will generate a detailed plan.md outlining all steps, dependencies, and risks, ensuring your project starts on a solid, validated foundation.

FAQPage Schema
How do I convert a vague project idea into a detailed implementation plan?

plan-down automates conversion of vague planning requests into a complete plan.md by assessing method clarity, applying adaptive workflow logic, and generating structured plans with milestones, dependencies, risks, and standards compliance.

What's the best way to decompose complex tasks across multiple phases?

Task decomposition happens through a four-phase workflow: method clarity assessment, clarification or enrichment, task decomposition via planner, and final plan.md generation, with support for both interactive and fully automated execution modes.

Can I validate project approaches using multiple AI models before planning?

Yes. In automated mode with unclear methods, plan-down chains multiple models for multi-model validation to enrich and validate implementation approaches before generating the final structured plan.

How do I ensure my project plan adheres to team standards and context?

plan-down reads context from CLAUDE.md and PROJECTWIKI.md files to embed existing standards, then generates plan.md output with explicit compliance and path selection aligned to your project environment.

Does plan-down handle both feature development and complex migrations?

Yes. The Skill applies to feature development, project roadmaps, migrations, and complex task decomposition, with adaptive workflow that adjusts based on method clarity and execution preference.

What happens if my project method is unclear or poorly defined?

plan-down detects unclear methods and either routes you to interactive clarification or applies multi-model AI validation in automation mode to enrich and refine the approach before plan generation.
