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

  • /mind Persistent 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.
