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 | $0.00339 | $0.00339 |
| Opus 5.5 | $0.00136 | $0.00136 |
| Sonnet 5.5 | $0.00068 | $0.00068 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
kyvault 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 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.
What it actually says
AGENTS.md — AI 助手工作守则
这是什么
kyvault —— AI 时代的开发者密钥与资产台账管理器（Rust）：AES-256-GCM 加密存本机， 工具凭别名取用，agent 不接触明文。核心承诺：减少明文密钥进入模型上下文。
关键文件
rust/：主程序源码（rust/src）与测试（rust/tests）。homebrew/：Homebrew tap 配方；packaging/：各平台打包。SKILL.md：agent skill 定义 —— agent 侧的用法口径以它为准。SECURITY.md：安全上报通道；密钥与加密相关改动前必读。docs/：设计文档与提案（outreach / proposals）。
常用命令
cd rust && cargo build # 构建
cd rust && cargo test # 测试
约定（安全红线）
- 任何改动不得把明文密钥打进日志、错误信息或 stdout；解密后的值只在注入目标进程时短暂存在。
- 加密实现（算法、nonce 生成、KDF）的任何改动都必须带测试与迁移说明，不允许静默换格式。
- 本仓库自己不用密钥做 CI 测试 —— 测试一律用 fixture 假值。
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.

kyvault AGENTS.md is an instructions file published in the GitHub repository webkubor/kyvault (4 stars, last pushed yesterday), licensed MIT. It adds 339 tokens to every session, about $0.0014 per session on Opus 5.5. 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 2026-10-26.
