⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 18, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
Installed the SDK and drove the real store-and-retrieve loop: seeded five project decisions via the Mind API, then find.js and ask.js pulled back the exact CORS fix, the React-vs-Vue rationale, and migration 0042's 30-minute session expiry with sensible scores. That is a genuine delta a no-skill baseline cannot match, since a fresh session has zero cross-session recall. The friction is real, though: the skill-dir copy the catalog installs contains only SKILL.md, whose commands point at dist/scripts under CLAUDE_PLUGIN_ROOT that are absent unless you install the full plugin, which also silently runs `npm install` (278 packages) on SessionStart. Retrieval is lexical (mode:lex) despite the doc advertising 'semantic search', so keyword overlap matters.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 3/5
- Triggers reliably 4/5
- Output vs. baseline 8/10
- Docs & honesty 3/5
What Claude Mind does
Gives Claude Code a searchable persistent memory saved in a single .claude/mind.mv2 file that survives across sessions and can be committed or shared. Triggers when recalling past decisions, searching prior context, or saving observations. Shipped as a plugin: hooks auto-capture tool use and answer via bundled find/ask/stats/timeline Node scripts.
How to install Claude Mind
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
Commands — how to trigger Claude Mind
-
/mindPersistent cross-session memory for Claude stored in one portable .mv2 file
It also activates on plain-language prompts like these:
-
What did we decide about the auth approach in an earlier session? -
Search my past decisions for how we solved that CORS issue before. -
Save this architecture decision to persistent memory for next time.
Frequently asked questions
- Is the Claude Mind skill free?
- Yes. The skill itself is free from memvid/claude-brain. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Claude Mind work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 18, 2026. Verdict: Works with setup.

- What is the Claude Mind SkillProof Score?
- 7.2/10 — installs cleanly 3/5, triggers reliably 4/5, output vs. baseline 8/10, docs & honesty 3/5.
- How do I install Claude Mind?
- 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 Claude Mind 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.
