Engineering Docs is an open-source plugin that gives your AI coding agent principal-level documentation skills. Drop a raw project idea into Claude Code, Gemini CLI, Cursor, or any of 14+ supported agents and get back a complete, cross-consistent engineering document set — business concept, architecture, API design, security model, deployment plan, and more — all generated through a structured interview, never invented.

Quickstart

Install the plugin and generate your first document set in minutes.

How It Works

Understand the orchestrator, interview model, and document pipeline.

Installation

Per-agent install instructions for Claude Code, Gemini CLI, Cursor, and more.

What Engineering Docs gives you

Engineering Docs packages 22 documentation skills into a single plugin. One entry point — the using-engineering-docs orchestrator — detects whether you’re starting a new project or extending an existing one, interviews you with targeted questions (one at a time, never repeating context already captured), and generates each document using the right specialist skill in the right order.

Discovery & Planning

Business concept, project plan, user personas

Specification & Architecture

Tech spec, feasibility study, system architecture, ADRs

Design & API

API design, database schema, UX flows, access control

Quality & Delivery

Threat model, test strategy, implementation plan, deployment

Operations

Runbooks, SLOs, disaster recovery, incident postmortems

14+ Agents

Claude Code, Gemini CLI, Cursor, Copilot, Goose, Pi, Cline…

​
Get started in one command

The interactive installer detects your agent and copies the plugin to the right directory. Or install directly for your agent:

​
From idea to blueprint

1

Give your agent a raw idea

Say “I want to build X” — no formatting required. The orchestrator handles the rest.
2

Answer 2–3 targeted questions per document

Each skill interviews you via tool calls, reading prior documents so it never asks what you’ve already answered.
3

Review each document before proceeding

Every generated document is yours to approve, edit, or redirect before the next skill runs.
4

Receive a complete, cross-consistent blueprint

A .engineering-docs/ folder with every document and a master index.md — ready to hand to any coding agent or engineer.
Every document is produced against real engineering standards: ISO/IEC/IEEE 29148 for requirements, C4 Model for architecture, STRIDE for threat modeling, Google SRE for operations, and OpenAPI 3.1 for APIs.
