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-search 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 9d 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.

supsub-search Skill

全量搜索:在订阅源(公众号、网站)和文章正文里同时搜,可按类型缩小范围。

先判范围:全站搜索 vs 用户自己的订阅

拿到一个词 X,看动词,不看 X 像不像专名

用户说法 意图 走哪
「搜一下 X」「查 X 相关文章」「全文搜 X」 检索 本 skill(全站)
「看一下最近 X 的内容」「X 最近有什么」「X 更新了吗」「读读 X」 浏览某主体的内容流 先比对订阅范围(见下)
「我的订阅 / 我的公众号 / 我的网站」 已限定本人范围 supsub-sub
「我的关注点」 已限定本人范围 supsub-focus

浏览意图的处理步骤:

  1. supsub sub list -o json + supsub focus list -o json
  2. 把 X 与 name / title包含匹配(忽略大小写)
  3. 命中订阅源 → supsub sub contents --source-id <sid> --type <t>;命中关注点 → supsub focus contents --id <fid>两边都命中就都列出来让用户选(同一个词很可能既是源名又是关注点主题);
  4. 命中后补一句「也可以全站搜 X 相关文章」,别把全局搜索这条路藏起来;
  5. 一个都没命中 → 直接执行 supsub search <X> 全站搜索,不要反问「要不要我帮你搜一下」。用户的浏览意图没有变,只是这个词不在他的订阅里;正确做法是搜完再说明「你没有订阅叫 X 的源,以下是全站结果」。

实测教训:「看一下最近 Anthropic 的内容」曾被直接送进全站 search,返回一堆第三方评论文章,而用户自己订阅的 Anthropic 官方博客源、以及「Anthropic 公司动态与 AI 前沿进展」关注点被完全绕过。用户提某个主体名时,他自己订阅的那份优先

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.
