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 5.1 | $0.00147 | $0.03163 |
| Opus 5 | $0.00073 | $0.01581 |
| Sonnet 5 | $0.00029 | $0.00633 |
| Haiku 4.5 | $0.00015 | $0.00316 |
Grade A, and why
mb-wiki 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 10d 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 — 377 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Wiki Skill
Create and maintain personal wikis with atomic notes, WikiLinks, and auto-deploy.
Need help? Type /mb-help + your question anytime. If conversation compacts, /mb-help reloads fresh context.
Pull Latest Updates (Always)
See references/pull-engine-updates.md for the standard Main Branch update check. Run it at the start of every /mb-wiki invocation.
Where Files Go
Wiki files go to YOUR WIKI REPO, not your business repo or the Main Branch engine.
your-wiki-repo/ <- Files saved here
├── src/content/notes/ <- Atomic notes (/mb-wiki add)
├── src/content/research/ <- Full research docs (/mb-wiki research)
└── src/content/updates/ <- Auto-generated updates (/mb-wiki recent)
~/.mainbranch/mb-wiki.json <- Config pointing to wiki repo
mainbranch/ (engine) <- Never modified by /mb-wiki
└── .claude/skills/mb-wiki/ <- This skill lives here
The skill reads ~/.mainbranch/mb-wiki.json to find your wiki repo location.

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.
