用外链检测连接器的工具，在提交外链前查来源、上线后验收链接、给用户自己的外链做垃圾外链体检。用户说「这个目录站能不能交」「帮我查查这些外链来源」「这个页面链到我了吗」「外链体检」「有没有垃圾外链」「竞品的外链」「AI 概览引用了谁」时使用。.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 外链检测

按 Google 的链接垃圾政策，在提交前查外链来源、在上线后验收链接、给用户自己的外链做体检。工具从不替用户提交任何东西；每个结论是一组信号和它们的证据，不是 Google 的判定。

## 用哪个工具

| 用户要做的事 | 工具 | 费用 |
|---|---|---|
| 某个页面有没有链到他、传不传权重、链接在页面哪里 | `verify` | 免费 |
| 看他自己的提交记录和提醒 | `submissions` | 免费 |
| 提交前查一批外链来源（目录站、榜单、投稿站） | `vet` | `free=True` 免费；否则每站约 0.01 USD，另加每批约 0.16 USD；`deep` 每站再加约 0.19 USD；`newcomers=True` 再看它现在还收不收新站（免费，每站多 20 到 60 秒） |
| 在他的关键词上排名的页面，也就是该去哪里出现 | `find` | 每个关键词约 0.005–0.006 USD，另加 0.012 USD |
| 他自己的外链画像；落在死页面或跳转页面上的外链 | `audit`、`lost` | 约 0.12 USD（`deep` 约 0.16 USD）；约 0.06 USD |
| 竞品拿到了、他还没有的外链 | `competitors` | 每次调用约 0.025 USD，3 个竞品约 0.20 USD，不超过 `max_usd` |
| 新站怎么起步：竞品上线头 90 天拿到的外链，和他自己同期对比，再给一份发布清单 | `competitors`，`early=True` | 每个站约 0.06 USD（含用户自己的站），每个竞品再加一次查链接页面：一个竞品加用户约 0.08 USD，3 个竞品最多约 0.35 USD，不超过 `max_usd`（默认 0.50）；清单前 `vetted` 个（默认 10）免费 vet，要一两分钟 |
| Google AI 概览在他的关键词上引用了谁 | `cited` | 每个关键词 0.002–0.006 USD，不超过 `max_usd` |
| 买家会怎么问 AI；AI 搜了什么、引用了谁、提到了谁 | `questions`、`asked` | 约 0.01 USD；每个问题约 0.12 USD，不超过 `max_usd`（只有 AIsa key 能查） |

查来源时先用 `vet` 的 `free=True` 免费看一遍，用户想要垃圾分和搜索历史时再付费查。

How to install

The exact contents, by fingerprint

mdr add zhuyansen/agent-skills-hub/backlink-guard@sha256:e7d3cd0c285a7fb7

The line at the top of this page pins the label v0.11.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
