SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the complexity of breaking down roadmap phases into manageable implementation plans, automating the decomposition process and recommending specialized agents for each plan.

Core Features & Use Cases

  • Automated Roadmap Decomposition: Converts high-level phase descriptions into detailed implementation plans based on dependencies and task ordering.
  • Agent Recommendation: Assigns specialist agents to each plan to ensure specialized attention and efficiency.
  • Plan Generation: Generates PLAN.md files for each decomposition that detail the scope, objectives, and expected outputs.

Quick Start

Generate a phase decomposition plan using the /legion:plan command with the 'phase-decomposer' skill.

FAQPage Schema
How do I break down a project roadmap into actionable phases automatically?

Automated roadmap decomposition converts high-level phase descriptions into detailed implementation plans based on dependencies and task ordering. It analyzes your roadmap file and outputs structured plans with defined scopes and objectives.

What is the best way to assign specialized agents to complex project management tasks?

Specialized agent assignment recommends expert agents for each decomposed implementation plan to ensure focused attention and efficiency. This automated allocation matches specific project phases with dedicated specialist agents.

How do I generate a detailed implementation plan from a high-level roadmap file?

Roadmap phase decomposition generates PLAN.md files for each phase that detail the scope, objectives, and expected outputs. You execute the planning command with your roadmap file to produce these structured implementation plans.

Can I use automated decomposition for complex project management scenarios with multiple dependencies?

Automated decomposition applies to complex project management scenarios by utilizing extended reasoning models for analysis. It processes task ordering and dependencies within your roadmap file to structure implementation plans effectively.

Do I need a specific input format to start roadmap planning and phase decomposition?

Roadmap planning and phase decomposition require a roadmap file as input for analysis. The process utilizes this file to automate task structuring, dependency resolution, and specialized agent allocation for your project phases.

What are the limitations of using automated tools for phase management and task structuring?

Automated phase management relies on extended reasoning models and requires a valid roadmap file, meaning poorly structured input or highly ambiguous phase descriptions may limit the accuracy of generated implementation plans and agent recommendations.
