SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill acts as a personal engineering coach, converting development sessions into structured learning that highlights workflow improvements, missed or applied software principles, and architectural insights to build a durable playbook over time.

Core Features & Use Cases

  • Analyze sessions to extract actionable workflow improvements and identify engineering principles demonstrated or missed.
  • Surface architectural insights and compile them into a reusable personal playbook that grows with each project.
  • Provide a repeatable retrospective workflow including LESSONS.md and CLAUDE.md integration for ongoing learning.

Quick Start

Invoke a retrospective on this session to generate a structured summary and entry for your engineering playbook.

FAQPage Schema
How do I turn a development session into a structured engineering playbook?

You can capture architectural insights by reviewing cross-project patterns and evaluating applied or missed software engineering principles. This identifies durable workflow improvements and compiles them into a reusable personal engineering playbook.

What is the best way to track missed software engineering principles during a project?

Tracking missed software engineering principles involves running a retrospective on your development session to identify gaps in your approach. It surfaces these missed concepts and queues them as actionable lessons and study items for ongoing learning.

How do I document cross-project patterns for long-term software architecture learning?

Document cross-project patterns by summarizing development sessions to surface recurring architectural insights. Compiling these insights into a personal playbook creates a durable reference that grows with each project and informs future architecture decisions.

Can I integrate development session lessons into LESSONS.md and CLAUDE.md files?

You can integrate session lessons into LESSONS.md and CLAUDE.md files by generating structured retrospective outputs. This workflow provides actionable lessons and playbook updates formatted specifically for seamless integration into these documentation files.

Does a retrospective workflow help identify actionable workflow improvements for software engineering?

A retrospective workflow helps identify actionable workflow improvements by systematically analyzing your development sessions. It extracts specific process bottlenecks and architectural insights, converting them into a structured engineering playbook for continuous improvement.
