stats

A command that reports statistics about Claude’s persistent memory file, including its size, number of memories, and recent activity.

In plain words
What is it for?
Use it to inspect memory storage and activity, including after the file is first created.
Why use it?
It gives you a quick view of how much stored memory exists and whether the file has been used recently.

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.

Per session 6 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 123 The whole file, excluding the scripts and references it only reads on demand.

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

stats 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 2d 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

Memory Statistics

Show statistics about Claude's persistent memory file including total memories, storage size, and recent activity.

Usage: /mind:stats

Execute the stats script:

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

Response Format

  • 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.

stats is a command published in the GitHub repository memvid/claude-brain (574 stars, last pushed 7mo ago), licensed MIT. It adds 6 tokens to every session and 123 once invoked, about $0.0000 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 2026-08-30.
