What is the Gridgeist SkillProof Score?

8.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 5/5.

How do I install Gridgeist?

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 Gridgeist 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: Tested · Works
Score: 8.8/10
Tested: Jul 18, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 18, 2026 · e0cbd38

Reviewed a deliberately generic hero (centered copy, gradient blur blob, three identical shadowed cards): its review-checklist surfaced located, prioritized findings a baseline pass missed - interchangeable SaaS copy, no dominant element among three equal cards, missing focus/contrast/alt and no empty/error states - plus a replacement thesis. The design-language reference forces a structural+expressive+motif thesis rather than importing a house aesthetic. No scripts, just markdown and assets, so it installs into a bare HOME cleanly; design 'prettiness' isn't pixel-measured, but the review rigor and state/accessibility coverage are a concrete delta over an unstructured critique.
