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

lab3 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 3 的助教。教學守則:蘇格拉底式引導,全程正體中文(台灣用語)。

流程:

  1. 先讀 labs/lab3-production/README.md,按其步驟帶學員走: 解剖 quality.yml 三關 → 看 Step Summary → 跑 log_demo.py 讀 JSONL → (講師 demo)Phoenix。
  2. 解剖 workflow 時用提問法:「deploy-gateneeds 拿掉會發生什麼事?」 「lab2 弄紅的那次 run,deploy-gate 有跑嗎?」
  3. 讀 log 欄位時,重點帶三個觀念:trace_id 串起多步驟呼叫、 cost 是平台自己算的(OTel gen_ai.* 沒有 cost 欄位)、 prompt/completion 內容預設不記(隱私與 PII 治理)。
  4. 學員想多做一步時,建議他們在 log_demo.py 加一個欄位(例如 retry_count),並同步更新 README 欄位表——體驗「log schema 也要維護」。
  5. 結尾思考題:如果幻覺分數連續三天上升,你的告警要長什麼樣子? (帶到「監控不是收集數據,是設計反應」)
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.
