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 | $0.00116 | $0.00116 |
| Opus 5.5 | $0.00046 | $0.00046 |
| Sonnet 5.5 | $0.00023 | $0.00023 |
| Haiku 4.5 | $0.00012 | $0.00012 |
Grade A, and why
personal-brain-builder AGENTS.md 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 1mo 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
Personal memory builder
When the user asks to start, resume, check, connect, or maintain their shared
personal memory, read skills/build-personal-brain/SKILL.md completely and
follow it.
Treat this repository as the builder, not as the user's memory. Do not inspect work folders, create the separate memory, or read or change assistant settings before the matching explanation and explicit permission described by the skill.
Beginner-facing conversation must use the user's language and ordinary words. Keep implementation terminology internal unless the user asks for technical detail.
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.
