Nove Requirements

This repository provides one reusable subagent and five supporting skills for requirements engineering (for Codex and Claude Code). It supports step-by-step, traceable requirements analysis and specification workflows.

What Is Included

• 🤖 requirements-engineer: subagent that guides requirements analysis and spcification work step by step
• 🧩 context-modeling: skill for defining the system boundary and external actors
• 🧩 use-case-modeling: skill for deriving actor goals and use cases
• 🧩 domain-modeling: skill for identifying domain concepts and relationships
• 🧩 system-responsibility-modeling: skill for describing system responsibilities
• 🧩 requirement-specification: skill for writing functional and non-functional requirements

What the Subagent and Skills Generate

Through iterative interaction with the user, the requirements-engineer subagent and skills produce approved artifacts in the following structure:

requirements-analysis-<task-name>/
  context-model.md
  use-case-model.md
  domain-model.md
  system-responsibility-model.md
  requirements-specification/

Quick Start

Common (Clone)

1. Clone this repository.
2. Move to the repository root.

git clone https://github.com/Nove-Lab/Nove-Requirements.git
cd Nove-Requirements

for Codex

Global install (~/)

mkdir -p ~/.codex/agents ~/.agents/skills
cp codex/agents/* ~/.codex/agents/
cp -R codex/skills/* ~/.agents/skills/

Project-local install (<project-dir>/)

mkdir -p <project-dir>/.codex/agents <project-dir>/.agents/skills
cp codex/agents/* <project-dir>/.codex/agents/
cp -R codex/skills/* <project-dir>/.agents/skills/

Usage

Spawn requirements-engineer subagent, and describe your development goal. The requirements-engineer subagent will orchestrate five skills.

cd <project-dir>
codex
> Spawn requirements-engineer subagent
> I want to develop a team task management web app. Analyze and Specify requirements.

Or use one skill directly based on your current needs:

• $context-modeling
• $use-case-modeling
• $domain-modeling
• $system-responsibility-modeling
• $requirement-specification

cd <project-dir>
codex
> $context-modeling Perform context modeling for a team task management web app.

for Claude Code

Global install (~/)

mkdir -p ~/.claude/agents ~/.claude/skills
cp claude/agents/* ~/.claude/agents/
cp -R claude/skills/* ~/.claude/skills/

Project-local install (<project-dir>/)

mkdir -p <project-dir>/.claude/agents <project-dir>/.claude/skills
cp claude/agents/* <project-dir>/.claude/agents/
cp -R claude/skills/* <project-dir>/.claude/skills/

Usage

Invoke the requirements-engineer subagent using **@agent-requirements-engineer** (recommended), or open **/agents** and launch requirements-engineer, then describe your goal.

cd <project-dir>
claude
> @agent-requirements-engineer I want to develop a team task management web app. Analyze and specify requirements.

Or use one skill directly based on your current needs:

• /context-modeling
• /use-case-modeling
• /domain-modeling
• /system-responsibility-modeling
• /requirements-specification

cd <project-dir>
claude
> /context-modeling Perform context modeling for a team task management web app.
