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 | $0.00068 | $0.01565 |
| Opus 5 | $0.00034 | $0.00783 |
| Sonnet 5 | $0.00014 | $0.00313 |
| Haiku 4.5 | $0.00007 | $0.00156 |
Grade A, and why
clone 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.
How it starts
The opening of the file, as written. The whole thing — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Clone
Package your agent's full context for transfer to a new vault.
What gets cloned: Everything in the agent folder : MEMORY.md, MEMORY-INDEX.md, memory/, and CLONE.md once generated. Also includes onebrain.yml and the OneBrain plugin.
What does NOT get cloned: your notes, projects, areas, knowledge, resources, archive, and logs.
Usage: /clone
Files Included in Clone Package
05-agent/MEMORY.md05-agent/MEMORY-INDEX.md← include MEMORY-INDEX05-agent/memory/← all memory files (was: context/ + memory/ separately; now merged)onebrain.yml← include onebrain.yml (has recap config).claude/plugins/onebrain/
Session Log Handling
When cloning, preserve recapped: and topics: fields on all session logs.
Do NOT strip these fields — the new vault should not reprocess already-recapped logs.
Archive Folder Option
AskUserQuestion: "Include [archive_folder]/[agent_folder]/memory/ (deleted memory files)?"
Options: include / skip
include: copy06-archive/05-agent/memory/into clone package (full history)skip: omit archive folder (clean fresh-feeling vault)
Step 1: Regenerate CLONE.md
Write [agent_folder]/CLONE.md (overwrite if it exists):
---
tags: [agent-clone]
updated: YYYY-MM-DD
---
# Agent Clone Manifest
## Identity
- Source: [agent_folder]/MEMORY.md
- Agent name: [read from [agent_folder]/MEMORY.md `## Identity & Personality` section — value of **Agent:** field]
- Last updated: [TODAY'S DATE]
## Index
[If [agent_folder]/MEMORY-INDEX.md exists, include a note that MEMORY-INDEX.md is present. Otherwise write: (none)]
## Memory Notes
[For each .md file in agent_folder/memory/ (skip .gitkeep and non-.md files), list: - filename : first line of file body (after frontmatter). If no .md files exist, write: (none yet)]
Step 2: Display Clone Summary
Show the user what will be cloned:
──────────────────────────────────────────────────────────────
📦 Ready to Clone
──────────────────────────────────────────────────────────────
✅ [agent_folder]/MEMORY.md identity and personality

✅ onebrain.yml vault configuration
✅ .claude/plugins/onebrain/ OneBrain plugin
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

clone is a skill published in the GitHub repository onebrain-ai/onebrain (25 stars, last pushed 4d ago), licensed Apache-2.0. It adds 68 tokens to every session and 1,565 once invoked, about $0.0003 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.
