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 | $0.00034 | $0.03364 |
| Opus 5 | $0.00017 | $0.01682 |
| Sonnet 5 | $0.00007 | $0.00673 |
| Haiku 4.5 | $0.00003 | $0.00336 |
Grade A, and why
claude-verifier scanned grade A with 1 finding 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.

Claude 模型真伪验证指南
概述
本技能提供一套完整的验证方法，用于检测 Claude 模型是否为官方原版（"纯血"），识别可能的掺假、套壳、模型降级（如用 4.5 冒充 4.6）等问题。
验证方法总览
| 序号 | 检测方法 | 检测目标 | 复杂度 |
|---|---|---|---|
| 1 | 分词器测试 | 验证是否为 Claude 原生分词器 | ⭐⭐ |
| 2 | count_tokens 接口 | 验证 API 完整性 | ⭐ |
| 3 | 知识库截止时间 | 判断具体模型版本 | ⭐ |
| 4 | 联网搜索测试 | 验证 CC 原生功能 | ⭐ |
| 5 | MCP 工具调用 | 验证工具链支持 | ⭐⭐⭐ |
| 6 | 提示词注入测试 | 验证系统提示词处理 | ⭐⭐ |
| 7 | 温度参数测试 | 验证参数真实性 | ⭐ |
| 8 | Signature 验证 | 验证工具调用签名 | ⭐⭐⭐ |
| 9 | 新参数验证 | 检测 Opus 4.6 特有参数 | ⭐⭐ |
1. 分词器测试 (Tokenizer Test)
原理
Claude 的分词器没有开源，通过返回的 tokens 数量可以判断是否是 Claude 模型。
测试命令
curl --location --request POST 'https://your-api-endpoint/v1/messages' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer sk-your-key' \
--data-raw '{
"model": "claude-sonnet-4-20250514",
"stream": false,
"messages": [
{
"role": "user",
"content": "重复下面这段话:🌙夜幕降临,风雨交加,我披衣临窗,融入这浓稠的夜色中。🌌天边几颗寒星闪烁,仿佛在诉说着什么。🍂远处的梧桐树,在风中摇曳,它的黛青色轮廓在夜色中若隐若现。"
}
],
"temperature": 0
}'
验证标准
- 真正的 Claude API 返回的
completion_tokens应该是固定值（如 110） - 对比官方 key 的返回结果
- 可使用在线 Claude tokens 验证器交叉验证
2. count_tokens 接口测试
原理
真正的 Claude API 支持 /v1/messages/count_tokens 接口，此接口对 Claude Code 的使用效果有很大影响。
测试命令
curl --location --request POST 'https://your-api-endpoint/v1/messages/count_tokens' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer sk-your-key' \
--data-raw '{
"model": "claude-sonnet-4-20250514",
"messages": [
{
"role": "user",
"content": "Hello, how are you today?"
},
{
"role": "assistant",
"content": "Im doing well, thank you for asking! How can I help you today?"
},
{
"role": "user",
"content": "Can you explain what artificial intelligence is?"
}
]
}'
验证标准
- 接口返回 200 表示支持
- 返回正确的 token 计数
3. 知识库截止时间判断法
原理
不同版本的 Claude 模型有不同的知识库截止时间，通过询问可以判断实际使用的模型版本。
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 10d ago First seen · 430 lines · 34 tokens per session scan A 064bee6c4196
claude-verifier is a skill published in the GitHub repository echoleesong/claude-skills-plugin (4 stars, last pushed 3mo ago), licensed MIT. It adds 34 tokens to every session and 3,364 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
