SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Coordinates a repeatable RETRO-driven workflow to perform retrospective formalization of Lean 4 projects, enabling consistent governance, cross-skill alignment, and documentation.

Core Features & Use Cases

  • RETRO protocol execution for Refactor-Extract-Test-Refine-Optimize across project scales (Solo to Large)
  • Cross-skill orchestration with related SKILLs (LEAN enforcement, zettelkasten, doc feedback, review council)
  • Embedded RALPH loop and per-phase governance templates with references to the lean-retro-methodology-handbook

Quick Start

Start a corpus retrospective session using the RETRO protocol with Lean 4 project alignment.

FAQPage Schema
What is retrospective formalization for Lean 4 projects?▼

Retrospective formalization applies a structured workflow to existing Lean 4 codebases using the RETRO protocol, which systematically refactors, extracts, tests, refines, and optimizes code for consistency and documentation.

How do I run a RETRO protocol session on a Lean 4 codebase?▼

Start a corpus retrospective session using the RETRO protocol to align Lean 4 projects, executing the Refactor-Extract-Test-Refine-Optimize phases with governance templates and embedded loops for consistent formalization.

Can I apply this retrospective formalization workflow to large-scale codebases?▼

Yes, the RETRO protocol scales across solo to large-scale Lean 4 codebases, providing per-phase governance templates and cross-skill orchestration to manage formalization and alignment effectively.

How does cross-skill alignment work during Lean 4 formalization?▼

Cross-skill alignment orchestrates related workflows like Lean enforcement, zettelkasten, documentation feedback, and review councils using a routing contract and handoffs to ensure consistent governance across projects.

What is the RALPH loop in the context of Lean project formalization?▼

The RALPH loop is an embedded iteration mechanism within the RETRO protocol that drives continuous refinement and optimization during the retrospective formalization of Lean 4 projects.

Do I need specific dependencies to use this Lean 4 RETRO workflow?▼

No specific dependencies are required to run the workflow, but it references a methodology handbook and integrates with related skills like Lean enforcement and zettelkasten for full cross-skill orchestration.
