What documentation is required as input for this skill?

This skill specifically targets the 11 reverse-engineering documents generated during Gear 2 of the StackShift pipeline, found in the docs/reverse-engineering directory.

What is the GitHub Spec Kit?

The GitHub Spec Kit is a framework for defining software features through structured specifications, implementation plans, and tasks to improve development clarity and AI assistance.

Where are the generated specification files stored?

By default, all output is saved to a .specify/ directory in your project root, though a custom output location can be configured.

Does this support existing (brownfield) projects?

Yes, it is designed to handle both greenfield (new) and brownfield (existing) repositories to help document and plan feature gaps.

Can I choose the level of detail generated?

Yes, you can configure the thoroughness to generate just specifications, specs with implementation plans, or a complete roadmap including granular tasks.

Learning & Documentation

Transforms reverse-engineering documentation into structured GitHub Spec Kit specifications with automated planning and task breakdowns.

This skill automates the transition from raw reverse-engineering analysis to a structured development roadmap using the GitHub Spec Kit framework. By processing documentation into a standardized .specify/ directory, it generates feature specifications, project constitutions, implementation plans, and granular task lists. It supports three levels of thoroughness to match project needs, ensuring that legacy codebases or complex requirements are translated into actionable, AI-ready implementation paths for spec-driven development.

Key Features

011 GitHub stars

02Built-in error recovery and manual fallback paths for complex documentation sets

03Three thoroughness levels: Specs-only, Specs + Plans, or Specs + Plans + Tasks

04Automatic generation of project 'Constitution' and feature-specific spec files

05Automated transformation of reverse-engineering docs into GitHub Spec Kit format

06Parallel subagent dispatch for high-speed plan and task generation

Use Cases

01Automating the creation of a comprehensive project roadmap and implementation backlog

02Standardizing documentation across teams using the GitHub Spec Kit framework

03Migrating legacy codebases by generating modern specifications from reverse-engineered analysis
