Token cost

What it costs to keep this loaded

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.

Security

Grade C, and why

supsub-sub scanned grade C with 2 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.

supsub-sub Skill

List, add, remove subscription sources, and browse the articles inside each source. Sources are typed MP(微信公众号)、WEBSITE(网站)或 X(推特 / Twitter 平台账号)。

⚠️ 关于字母「X」的歧义(务必先读)

本文档里 X 有两种完全不同的含义,不要混淆:

  1. --type X —— 这是一个真实的 sourceType 枚举值,专指 推特 / Twitter / X 平台账号
  2. 占位符 X —— 用户口语里说「订阅 X」「取消订阅 X」「X 公众号最近的文章」时,这里的 X 通常只是一个占位代号,代指某个具体账号(可能是公众号、网站,也可能就是名字里带 X),与推特无关

判定规则:

  • 只有当用户**明确提到「推特 / Twitter / X 平台」**时,才使用 --type X
  • 用户说「订阅 X」「X 公众号」「看 X 的文章」而没有提到推特平台时,不要据此推断 --type X;这里的 X 是占位符,应按其真实类型(多为 MPWEBSITE)处理。

Prerequisites

  • 安装:curl -fsSL https://raw.githubusercontent.com/SupSub-AI/supsub-cli/master/scripts/install.sh | bash(native 安装,装到 ~/.local、支持后台自动更新);或包管理器 npm i -g @supsub/cli / pnpm add -g @supsub/cli
  • 已登录:supsub auth status 显示 Authenticated(首次使用先 supsub auth login
  • 未授权(exit 2 / UNAUTHORIZED)时不要止步于「你未登录」:直接运行 supsub auth login 为用户打开浏览器授权(命令会自动打开浏览器并阻塞等待授权,请用足够长的超时,如 10 分钟;用户只需在浏览器点确认,无需在终端输入任何内容),授权成功后重试原命令。无浏览器 / 无头环境再回退为提示用户 SUPSUB_NO_BROWSER=1 supsub auth login

Commands

List subscriptions

supsub sub list [--type <MP|WEBSITE|X>]
Flag Default Description
--type — (all) 过滤来源类型:MP(公众号)/ WEBSITE(网站)/ X(推特)

Each row includes: sourceId, sourceType, name, img, description, unreadCount。表格模式下 类型 列会把 sourceType 显示为中文:MP→公众号、WEBSITE→网站、X→推特。

# 列出全部订阅
supsub sub list

# 仅看公众号
supsub sub list --type MP

# 仅看网站
supsub sub list --type WEBSITE

# 仅看推特(X 平台账号)
supsub sub list --type X

# 导出 JSON
supsub sub list -o json

JSON shape: {"success":true,"data":[{"sourceType":"MP","sourceId":12345,"name":"...","img":"...","description":"...","unreadCount":3}, ...]}


Add a subscription

sub add 有两条互斥入口,对应两种"拿到的 ID 形态":

# A) 全局搜索 / 已收录源 → 用内部正整数 sourceId
supsub sub add --source-id <id> --type <MP|WEBSITE|X> [--group <gid>]...

# B) mp search 发现的微信原生公众号 → 用 base64 字符串 mpId
supsub sub add --mp-id <mpId> [--type MP] [--group <gid>]...

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.
