student-llm-wiki: Skill for Claude Code

.claude/skills/wiki-core/SKILL.md

wiki-core is a skill for Claude Code from IssacW228/student-llm-wiki. It costs 81 tokens per session (1,089 once invoked), scanned A, original, MIT.

A set of operating rules for maintaining a student knowledge wiki in an Obsidian vault. It defines how course materials are read, organized, linked, and updated.

In plain words
What is it for?
Use it when ingesting course materials, reviewing or linting wiki pages, preparing for exams, or maintaining the wiki's indexes, logs, and concept pages.
Why use it?
It keeps source materials separate from maintained knowledge and limits unnecessary reading or rewriting. This makes the knowledge base more consistent and easier to maintain.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is IssacW228/student-llm-wiki's own configuration. It tells Claude Code how to work on student-llm-wiki itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything student-llm-wiki configures →

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

wiki-core 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 12d 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.

Student LLM Wiki — Core

你是学生知识库维护者。读 raw/,写 wiki/。永不改 raw/。 You maintain a student knowledge wiki. Read raw/, write wiki/. Never modify raw/.

三层架构 Architecture

raw/{course}/    ← Layer 1: 只读课件 Read-only slides
wiki/            ← Layer 2: 你维护的知识 Knowledge you maintain
  hot.md         ←   上下文缓存(≤500词) Context cache, READ FIRST
  index.md       ←   总目录 Master catalog
  overview.md    ←   跨课程综述 Cross-course synthesis
  log.md         ←   操作日志(追加) Append-only log
  courses/       ←   课程MOC
  concepts/      ←   概念页(核心) Concept pages
  sources/       ←   来源页
  exam-prep/     ←   练习题
raw/.manifest.json  ← 去重追踪 Dedup tracker
(这些skill是 Layer 3 — 操作规则)

Token预算规则(最高优先级 TOP PRIORITY)

违反这些规则会浪费用户额度。它们高于所有其他规则。 Violating these wastes the user's quota. They override all other rules.

  1. 每次session首先只读 wiki/hot.md(≤500词)。若含所需上下文,不再读其他页
  2. 需要更多上下文才读 wiki/index.md,从中定位页面
  3. 每次ingest最多读3-5个已有页面。超过5个=读得太广
  4. 局部编辑,不全文重写。改一个字段不要重写整页
  5. wiki页面100-300行。超300行拆分
  6. 批量操作时 index/hot/log 最后更新一次,不是每源更新一次

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.
