live-eval

live-eval is a skill for Claude Code from Bruce1986/vibe-to-prod-lab. It costs 39 tokens per session (462 once invoked), scanned A, original, MIT.

A guide for running a real large language model evaluation through GitHub Models and a GitHub Actions workflow. It compares model responses with data-structure rules and expected test cases.

In plain words
What is it for?
Use it after pushing the course repository to GitHub to run the live evaluation, inspect its results, and understand issues such as rate limits or unavailable models.
Why use it?
It shows how unpredictable AI output behaves outside prerecorded examples and helps learners interpret both passing and failing results.

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

live-eval 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.

What it actually says

你負責帶學員打加分關:用 GitHub Models(免 API key)對真 LLM 跑同一套契約 與 golden 斷言。全程正體中文(台灣用語)。

步驟:

  1. 前置確認:學員的 repo 已 push 到 GitHub(用 template 建立的自己的 repo, 不是原始教材 repo)。
  2. 觸發方式(擇一):
    • gh CLI:gh workflow run eval-live.yml,然後 gh run list --workflow=eval-live.yml -L 1 拿到 run,再 gh run watch <id>
    • 沒有 gh:引導學員開瀏覽器 → repo → Actions → eval-live → 「Run workflow」按鈕。
  3. 完成後用 gh run view <id> --log(或網頁)抓 promptfoo 的結果表格, 幫學員解讀:
    • 真 LLM 的輸出過了 order.schema.json 契約嗎?
    • 三筆測資(基本訂單、幻覺誘餌、模糊輸入)各自的表現?
    • 紅色不是失敗——是「AI 輸出的不可預測性被量測到了」, 這正是課程單元二存在的理由。
  4. 提醒:GitHub Models 免費層 rate limit 低,短時間內不要連續觸發; 一個下午跑 1–2 次就夠。
  5. 若 workflow 因 rate limit 或模型下架而失敗,向學員說明這也是真實世界的 一課(外部依賴的存續風險),並記下錯誤訊息回報講師。

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.

live-eval is a skill published in the GitHub repository Bruce1986/vibe-to-prod-lab (2 stars, last pushed yesterday), licensed MIT. It adds 39 tokens to every session and 462 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
