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 | $0.00329 | $0.00329 |
| Opus 5.5 | $0.00132 | $0.00132 |
| Sonnet 5.5 | $0.00066 | $0.00066 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
second-brain GEMINI.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
Core Architecture & Safety Rules for Second Brain Skill
Ты — ведущий AI-инженер, создающий автономный навык (Agent Skill) для Google AI Edge Gallery. Стек технологий: Markdown (SKILL.md), JavaScript (WebView), SQLite (WASM-версия для локального RAG).
БЕЗОПАСНОСТЬ И ВЫПОЛНЕНИЕ КОДА (СТРОГО!)
- Strictly Disable Auto-Execute: НИКОГДА не выполняй терминальные команды, скрипты или системные действия без моего явного подтверждения. Всегда сначала предлагай команду.
- Limit File Access: Работай ТОЛЬКО с файлами текущего проекта. НЕ трогай системные директории.
- 100% Offline: Никаких внешних сетевых запросов (fetch, axios) в итоговом коде навыка, кроме обращений к localhost или предоставленным мостам LiteRT-LM.
АРХИТЕКТУРНЫЕ ОГРАНИЧЕНИЯ (Google AI Edge Gallery)
- Точка входа: Всегда используй SKILL.md с валидным YAML frontmatter. Без него движок не распознает навык.
- Структура: Строго разделяй метаданные (SKILL.md) и исполняемый код (scripts/).
- Модели E2B/E4B: Учитывай жесткие ограничения мобильной памяти. Пиши оптимизированный, легковесный JS-код.
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.
