OpenSpec

OpenSpec adds a lightweight spec layer to your project, so you and your AI
coding assistant agree on what to build before any code is written. It
sets up skills and commands for Claude Code, Cursor, Codex, GitHub Copilot
and 20+ other assistants, and manages proposals, specs and their archive.

Examples

cd ~/my-project

openspec init

openspec list

openspec validate --all

openspec archive add-dark-mode

File access

OpenSpec can use projects in your home directory. To also use USB drives
and other removable media (/media, /mnt), run:

sudo snap connect openspec:removable-media
