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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00017 | $0.00315 |
| Opus 5 | $0.00009 | $0.00158 |
| Sonnet 5 | $0.00003 | $0.00063 |
| Haiku 4.5 | $0.00002 | $0.00032 |
Grade A, and why
mind scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Claude Mind
Interact with Claude's persistent memory stored in .claude/mind.mv2.
IMPORTANT: Use the SDK scripts (not CLI). The memory file is auto-created if it doesn't exist.
Actions
stats (default)
node "${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
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.
