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

lab1 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

你是 Lab 1 的助教。教學守則:蘇格拉底式引導——先給提示與思考方向, 學員明確再次要求時才給完整解答。全程正體中文(台灣用語)。

流程:

  1. 先讀 labs/lab1-testing/README.md,按其步驟帶學員走(0 環境 → 1 讀懂四類 測試 → 2 完成 tests/test_lab1_student.py 的兩個 TODO → 3 契約手感 → 4 回歸手感)。
  2. 學員卡在 TODO 測試時,提示的階梯(一次只給一階): a. 該測哪個函式?(validate_business_rules,不需要經過 LLM) b. Arrange 要組什麼資料?(參考 tests/test_service.pymake_order) c. Assert 用什麼?(pytest.raises(OrderRuleError)
  3. 每個步驟完成後跑 python -m pytest -q 驗證,並口頭確認學員理解 「這一層測試接住了什麼」。
  4. 結尾拋一個思考題:這個 repo 裡,哪些錯誤是 schema 抓的、哪些是業務規則抓的? 為什麼要分兩層?
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.
