## Findings

No check matched anything in these tool definitions.


## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `audit_cn_citability`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
审计一个网站/页面能否被中文 AI 搜索（豆包、DeepSeek、文心、Kimi 等）抓取、解析与引用。

    一次抓取完成六层检查：可抓取（含中国爬虫矩阵与边缘层拦截实测）、可解析、可引用、
    实体一致、分发、可信可自验；返回 0-100 分与 A-F 等级、逐项证据、优先修复清单。
    用途场景：客户站点体检、上线前自检；传 compare_with 可做竞品对比（逐层与逐项差异）。
    注意：只做确定性检查，不调用大模型；评分口径见 scoring_version。
    
```

### `plan_fixes`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
按缺口生成优先修复计划（可直接交给客户或工程执行）。

    两种用法：① 传 fail_ids（逗号分隔的自查项编号，如 "L1-3,L2-4"）；② 传 url，工具先审计再出计划。
    返回：按权重排序的修复项、每项「为什么」「怎么补」「验收方式」。
    
```

### `probe_source_pool`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
探测一个中文问题在信源池里的实际占位分布，并判断你的品牌/域名是否在池子里。

    原理：AI 答案只能引用「已进入检索池」的来源。若目标问题下主流信源被平台型站点
    （知乎/公众号转载站/百家号/CSDN 等）占满而你不在其中，再好的站内优化也不会被引用。
    返回：结果域名分布、平台归类、是否命中你的品牌/域名、同题竞品域名清单、建议动作。
    参数：question 用户真实会问的问题原话；brand 品牌词（如「合尘猫」）；domain 你的域名（如 savantcat.cn）。
    
```

### `score_visibility`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
按五大核心指标 + 语义角色分权，计算 AI 搜索可见度并输出可自验的测量报告。

    输入 samples 为 JSON 字符串：
    {"brand":"合尘猫","domain":"savantcat.cn","baseline_negative":3,
     "fact_points":["服务范围","交付周期","定价方式"],
     "samples":[{"question":"Q1","platform":"DeepSeek","run":1,"answer":"原文回答……",
                 "role":"independent|joint|citation_only|none",
                 "sentiment":"positive|neutral|negative",
                 "facts":"accurate|partial|wrong|unverifiable",
                 "facts_found":["服务范围"],"as_of":"2026-09-19"}]}
    口径：每题建议多轮（同一问题重复 7-8 次）；role 分级对应语义角色权重；
    返回五大指标、语义角色加权分、逐题明细与「原文摘录」（便于客户自验）。
    verify_citations=True 时会实测 AI 回答里引用的 URL 是否真的可访问（幻觉守卫）；
    extract_claims=True 时会把回答中的数字声明单独列出并标记为未核验。
    
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `diff_observations`

- The name "diff_observations" says "diff": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
对比某 identity 的**最近两次观测**，判定提升/退化/中性（带阈值与样本门槛说明）。

    判定门槛：相对变化 >= 20% **且** 绝对变化 >= 0.05 才算"显著"（severity: rise / sharp_drop）。
    样本 n < 20 一律返回 severity=low_n，**不给出升降结论**——这是防误报的硬门。

    Args:
        identity: 品牌名或域名
        kind: 观测类型，留空取全部
        series: 题集/口径标识，留空取全部
    
```

### `list_signals`

- The name "list_signals" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
列出**已检测到的变化信号**（visibility 提升/退化等），带生命周期（first_seen / resolved_at）。

    Args:
        status: open（未解决，默认）/ resolved（已解决）/ all
        limit: 最多返回条数
    
```

### `query_history`

- The name "query_history" says "query": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
查某个品牌/域名在**历史观测**中的时序（多次采样的轨迹）。

    数据来自本工作室按周期采样的记录（写入走 CLI，服务本身只读）。
    **只在同一 series（同一题集/同一口径）内纵向比较**，不同 series 的值不可直接比大小。

    Args:
        identity: 品牌名或域名，如 "合尘猫" / "savantcat.cn"
        kind: 观测类型，留空取全部。常用：mention_rate(提及率) / citation_rate(引用率) /
              visibility_score(可见度分) / rank(排名) / robots_policy / llms_txt
        series: 题集/口径标识，留空取全部
        limit: 每条 series 最多返回的最新点数
    
```
