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 5.1 | $0.00013 | $0.00252 |
| Opus 5 | $0.00006 | $0.00126 |
| Sonnet 5 | $0.00003 | $0.00050 |
| Haiku 4.5 | $0.00001 | $0.00025 |
Grade A, and why
gbrain-maintain 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 9d 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
Maintain Skill
Workflow
- Check stale pages with
gbrain list --limit 50and read candidates that have not been touched recently. - Compare compiled truth against
gbrain timeline <slug>to catch pages whose state no longer matches newer evidence. - Use
gbrain backlinks <slug>to find orphans and weakly connected pages. - Review tag consistency with
gbrain tags <slug>andgbrain stats. - Refresh semantic recall with
gbrain embed --staleafter material page updates.
Output
Write the maintenance pass back into the brain as a dated source page, for example:
cat report.md | gbrain put sources/maintenance-$(date +%Y-%m-%d)
Rules
- Fix contradictions in compiled truth, not by adding a second conflicting paragraph.
- Delete nothing unless you are certain it is duplicate or broken.
- Maintenance is allowed to create follow-up tasks, but it should not invent facts.
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.

gbrain-maintain is a skill published in the GitHub repository laozhong86/gbrain (8 stars, last pushed 5mo ago), licensed MIT. It adds 13 tokens to every session and 252 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.
