KSDD — for Claude Code, Codex, opencode, Antigravity & Copilot
From raw brainstorm to an implementable design system.
Slash commands that guide every product step with a human approval checkpoint between stages.

9 commands. One method.
Each command reads the previous artifact, asks structured questions, and stops before advancing.
Where it runs
One method, five coding agents.
Install once and run KSDD in Claude Code, OpenAI Codex, opencode, Google Antigravity, or GitHub Copilot — the same commands, invoked the way each agent expects.
Install for every agent at once
ksdd install --codex --opencode --antigravity --copilotOr add only the ones you use — each target has its own flag and KSDD_WITH_* env var.
How you invoke a command
The same command, three naming styles. Example: the start command.
| Claude Code | OpenAI Codex | opencode · Antigravity · Copilot |
|---|---|---|
/ksdd:start | /prompts:ksdd-start | /ksdd-start |
Why it matters
Why it matters
Human approval between stages
Not 'agent decides everything'. You review, adjust, and only then advance.
Cumulative artifacts
SPEC.md references brainstorm.md; architecture.md and DESIGN.md reference both.
Stack agnostic
The method doesn't pick your tools. Your team and your codebase do.
