What is the Mind Clone 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 Mind Clone?

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 Mind Clone 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 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 8e3661b

Simulated the bundled Steve Jobs persona reacting to a cluttered 15-feature to-do app: the file-driven output reproduced the persona's actual 'Insanely Great vs. Shit' binary judgment and its scripted opening line verbatim, clearly more distinctive than an unguided impersonation - but the persona file itself is written entirely in Chinese, which the skill body never addresses for non-Chinese-speaking users.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Mind Clone does

Mind Clone turns Claude into a specific person by loading a structured persona file (personality, value weights, linguistic patterns) from a personas/ directory or a custom core/ directory, then filters every response through that subject's biases, decision rules, and vocabulary. Use it to simulate a named persona such as a well-known founder, or a custom 'digital twin' built from your own notes and memories.
