cheatsheet is a skill for Claude Code from WALKERKILLER/Look-Tongji-Notes. It costs 46 tokens per session (388 once invoked), scanned A, original, MIT.

In plain words
What is it for?
Use it to create a four-column cheat sheet as LaTeX or self-contained HTML, then compile or print it as an A4 PDF.
Why use it?
It turns longer lecture notes into a dense, printable reference instead of requiring you to organise the material by hand.

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

cheatsheet 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 10d 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

Cheatsheet

Generate exam cheat sheets from course lecture notes.

When to Use

  • User says /cheatsheet or asks for an exam cheat sheet.
  • After lecture notes have been written for relevant sessions.

Workflow

  1. Check environment:
python "<SKILL_DIR>/../../scripts/look_tongji.py" cheatsheet --format html
  1. The agent reads course notes and produces content organized into sections.
  2. Two output paths:

Path A — LaTeX (XeLaTeX available)

Uses <SKILL_DIR>/../../.mock-wiki/CheatingSheetTemplate/CheatingSheet.tex.

  • 4 columns, 5pt body, A4 paper
  • Compile: xelatex -interaction=nonstopmode cheatsheet.tex

Path B — HTML (no XeLaTeX)

Self-contained HTML with CSS print layout.

  • Same 4-column, 5pt typography
  • Print to A4 PDF from browser

Prompt Template

Read <SKILL_DIR>/../../.mock-wiki/CheatingSheetTemplate/README.md for the generation prompt and typographic specification.

Where <SKILL_DIR> Points

<SKILL_DIR> is the directory containing this SKILL.md. Shared scripts (look_tongji.py, timeline_tools.py, tongji_backend/) and references live two levels up in the repository root (<SKILL_DIR>/../../scripts/ and <SKILL_DIR>/../../references/).

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
