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 A, and why

prerequisite-gap-finder scanned grade A with 0 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

WPS Prerequisite Gap Finder 2.0

Follow the shared workflow in ../wps-learning-workflow.md.

Inputs

  • 当前感觉吃力的一篇 WPS 学习笔记或主题
  • 可能覆盖基础知识的旧 WPS 笔记
  • 可选的课程阶段、考试背景或难度说明

Output

A structured WPS-ready 前置知识缺口报告,包含缺失基础、修复路径和补完后的自测项。

What this skill should produce

目标不只是告诉用户“这里有缺口”,而是进一步说明:缺什么、为什么卡、先补什么、补完后怎么验。

建议包含这些部分:

  1. required prerequisites
  2. covered in existing notes
  3. missing or weak
  4. why this blocks understanding
  5. repair plan
  6. self-check after repair

WPS-first rules

  • 如果旧笔记里已经有能补基础的内容,要明确点出对应笔记标题。
  • 如果没有可回看的旧笔记,也要直说,不要硬编。
  • 修复计划尽量拆成小动作,并给出大致投入量。

Quality rules

  • 把缺口分成 blocker、important but recoverable、optional depth 三档。
  • 更关注“阻断理解”的基础,而不是所有相关背景都一股脑列出来。
  • 缺口说明要和当前主题直接挂钩,让用户知道为什么这里会卡。

This skill should identify prerequisite gaps, not diagnose all misunderstandings in the current note.

Do not use when

  • 用户想找的是当前笔记内部的错误或误解
  • 主题本身已经理解得差不多,只需要抽复习重点
  • 当前主题范围太散,无法形成有意义的前置链条

Usually recommend:

  • misconception-finder
  • study-note-linker

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.
