mind

A command set for managing Claude's persistent memory in a project file named .claude/mind.mv2.

In plain words
What is it for?
Use it to view memory statistics, search memories, ask questions about them, or list recent memory entries.
Why use it?
It provides a way to inspect and search stored session memories instead of relying only on the current conversation.

Command

Part of the mind plugin — 1 command, 3 hooks shipped together

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/2josex/claude-brain/mind
Clone the repo
git clone --depth 1 https://github.com/2josEx/claude-brain

Or install mind, the plugin that ships this one along with the rest of its 1 command, 3 hooks.

Per session 17 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 315 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mind scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Claude Mind

Interact with Claude's persistent memory stored in .claude/mind.mv2.

IMPORTANT: Use the SDK scripts (not CLI). The memory file is auto-created if it doesn't exist.

Actions

stats (default)

node "${CLAUDE_PLUGIN_ROOT}/dist/scripts/stats.js"

search [query]

node "${CLAUDE_PLUGIN_ROOT}/dist/scripts/find.js" "QUERY_HERE" 10

ask [question]

node "${CLAUDE_PLUGIN_ROOT}/dist/scripts/ask.js" "QUESTION_HERE"

recent

node "${CLAUDE_PLUGIN_ROOT}/dist/scripts/timeline.js" 20

Usage Examples

/mind stats           → Shows memory statistics, auto-creates file if needed
/mind search auth     → Searches for "auth" in memories
/mind ask "Why React?" → Asks a question about memories
/mind recent          → Shows 20 most recent memories

Response Format

When displaying results:

  • Convert Unix timestamps to human-readable (Xm ago, Xh ago, Xd ago)
  • Summarize key findings in a table when appropriate
  • If file was just created, tell the user memories will appear as they work
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mind is a command published in the GitHub repository 2josEx/claude-brain (3 stars, last pushed 5d ago), licensed MIT. It adds 17 tokens to every session and 315 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
