Yes. The skill itself is free from gabelul/stitch-kit. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Stitch Setup SkillProof Score?

8.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 4/5.

How do I install Stitch Setup?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Stitch Setup with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 8.8/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · fe56c2b

The troubleshooting table catches a real, non-obvious gotcha (projectId/screenId must be numeric only, no 'projects/' prefix) that a generic MCP-setup answer would not know; but the whole skill hinges on manually getting a Stitch API key from stitch.withgoogle.com/settings first.
