Domain Map
Keeps your project's glossary and decision records sharp.
What it does
Build and sharpen a project's domain model. Use when discussing codebase terminology, writing or editing a GLOSSARY.md, or recording or editing an ADR.
Install in under a minute
Mac or Linux, after you download
unzip domain-map.zip -d ~/.claude/skills/Windows PowerShell
Expand-Archive domain-map.zip -DestinationPath $HOME\.claude\skills- Start a new Claude Code session so it sees the skill.
- Ask in plain words, for example: "Use Domain Map on this project."
- Unzip the download, then zip just the domain-map folder if your computer added an extra folder.
- In Claude.ai, open Settings, then Capabilities, and upload it under Skills.
- Turn the skill on and ask Claude to use it.
Domain Map uses the open SKILL.md format, so it also works in agents like Cursor, Gemini CLI, GitHub Copilot and Codex. Copy the domain-map folder into that agent's skills folder, for example .cursor/skills/ or .github/skills/ in your project.
