## What it is
Agent OS is a lightweight, open-source system for documenting coding standards from your codebase and injecting them into AI coding agents like Claude Code and Cursor. It also provides enhanced spec-shaping workflows for spec-driven development with AI.

## Use cases
- document coding standards from an existing codebase
- inject team conventions into AI coding agent prompts
- write better specs for spec-driven AI development
- keep AI agents aligned with team patterns and architecture
- onboard legacy codebases to AI-powered development
- standardize agentic workflows across a team

## When to choose
- you use AI coding agents like Claude Code or Cursor and want them to follow your team's conventions
- you want to extract and document tribal knowledge from an existing codebase
- your team wants a consistent spec-driven development process with AI

## When to avoid
- you need a fully automated code generation tool rather than a standards and workflow system
- you don't use AI coding assistants in your development process
- you want strict enforcement or linting of standards rather than context injection

## Facets
- artifact type: framework
- maturity: active
- function: developer-tools, documentation, workflow-automation, prompt-engineering
- domain: developer-tools, artificial-intelligence
- platform: cli, cross-platform
- tags: ai-coding-agents, spec-driven-development, coding-standards, claude-code, cursor, context-injection, automation
