SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill generates a comprehensive, file-by-file implementation plan by researching a codebase and related Trellis issues, providing precise guidance before coding.

Core Features & Use Cases

  • Research-driven planning: analyzes the repository structure and existing patterns to produce exact file changes and dependencies.
  • Issue-aligned rollout: creates plan segments tied to Trellis issues, outlining tasks across files, modules, and interfaces.
  • Actionable outputs: outputs a detailed list of modified, added, or removed files with concrete change descriptions and rationale.

Quick Start

Use this skill to generate an implementation plan for a Trellis issue, detailing every file change required to implement the described feature.

FAQPage Schema
How do I generate a file-by-file implementation plan from a codebase?

To generate a file-by-file implementation plan, this skill researches your repository structure and existing patterns to output a detailed list of modified, added, or removed files with concrete change descriptions and rationale.

What is issue-aligned codebase planning for cross-file refactors?

Issue-aligned codebase planning for cross-file refactors analyzes repository context and issue details to produce a structured list of file changes, dependencies, and implementation steps before coding begins.

Can I use this to plan feature integration across multiple modules?

Yes, you can plan feature integration across multiple modules. It applies to software engineering tasks requiring cross-file changes, refactors, or feature integration described in your issues.

Do I need a Trellis issue to generate an implementation plan?

Yes, you need a Trellis issue. The skill generates a detailed implementation plan by researching the target codebase and applying it to software engineering tasks described in Trellis issues.

What's the best way to outline exact file changes and dependencies before coding?

The best way to outline exact file changes and dependencies is using research-driven planning that analyzes repository structure to produce actionable outputs tied to your issue tracking.

When do I need a detailed implementation plan for a Trellis issue?

You need a detailed implementation plan for a Trellis issue when you face software engineering tasks requiring cross-file changes, refactors, or feature integration and require precise guidance before coding.
