Library-First-Engineering

Structured file-based pipeline for reliable software delivery

Runs a disciplined plan-build-verify-archive pipeline for software projects using file-based handoffs between Architect, Builder, Inspector, and Archivist personas. Prevents hallucinated logic, lost context, and architecture decay by storing every plan, test report, and decision in versioned project files. Includes security, performance, complexity, dependency, and test-quality checks so every change ships verified and documented.

npx skills add StChiotis/Library-First-Engineering --all -g -y

Available:

Directs the agent to read the pipeline state and protocol files first, then route all work through the assembly line, allowing only the boot, navigation, scout, and domain-extraction commands to be typed directly.

Frequently Asked Questions

FAQPage Schema

How to install Library-First-Engineering?▼

Run `npx skills add StChiotis/Library-First-Engineering --all -g -y` in your terminal to install all skills globally.

What problem does Library-First Engineering solve?▼

It stops AI coding sessions from hallucinating business logic, losing context, and producing tangled architecture by forcing every step through documented plans and independent verification.

How do I start a session with LFE?▼

Run /lfe-boot at the start of every session. It reads the pipeline state, detects interrupted work, and tells you exactly which step comes next.

Does LFE work with Claude Code, Cursor, and other tools?▼

Yes. It is language-, IDE-, and model-agnostic, with adapters for Cursor, Windsurf, Cline, Copilot, and a plain-text system prompt for any chat interface.

Can I use LFE for small quick fixes?▼

Yes. The /lfe-scout command handles minor fixes of up to three files without running the full planning pipeline, and escalates automatically if the change turns out to be structural.
