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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00052 $0.00991
Opus 5.5 $0.00021 $0.00396
Sonnet 5.5 $0.00010 $0.00198

Security

Grade A, and why

lesson-quiz 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 2mo 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.

Lesson Quiz

这是一个针对单个 OpenCode lesson 的完整互动测验 skill,用于检查用户对某一课的理解程度。

Instructions

Step 1: 确认 lesson

如果用户提供了参数,就映射到 lesson 目录:

  • 01 / slash-commands / commands → 01-slash-commands
  • 02 / memory → 02-memory
  • 03 / skills → 03-skills
  • 04 / subagents / agents → 04-subagents
  • 05 / mcp → 05-mcp
  • 06 / hooks → 06-hooks
  • 07 / plugins → 07-plugins
  • 08 / checkpoints → 08-checkpoints
  • 09 / advanced-features / advanced → 09-advanced-features
  • 10 / cli → 10-cli

如果用户没提供参数,使用 AskUserQuestion 分 2-3 轮让用户选择 lesson。


Step 2: 读取 lesson 与题库

先读取:

  • <lesson-directory>/README.md
  • references/question-bank.md

优先使用题库中该 lesson 的预置题。
如果题库不足 8 题,可根据 lesson README 补充生成,但必须保持与 lesson 内容一致。


Step 3: 询问测验时机

用 AskUserQuestion 询问用户当前是在:

  1. Before (pre-test)
  2. During (progress check)
  3. After (mastery check)

不同 timing 会影响结果解读。


Step 4: 出题

  • 每次固定 8 题
  • 每轮 2 题,共 4 轮
  • 混合概念题和实践题
  • 每题使用 AskUserQuestion,提供 3-4 个选项

每题必须包含这些信息:

  • category
  • question
  • options
  • correct
  • explanation
  • review

记录用户答案,最后统一评分。


Step 5: 评分与结果输出

每题答对记 1 分,总分 8 分。

等级:

  • 8:Mastered
  • 6-7:Proficient
  • 4-5:Developing
  • 2-3:Beginning
  • 0-1:Not yet

输出格式必须包含:

## Lesson Quiz Results: [Lesson Name]

**Score: N/8** — [Grade]
**Quiz timing**: [Before / During / After]
**Question breakdown**: N conceptual correct, N practical correct

### Per-Question Results
| # | Category | Question (short) | Your Answer | Result |

### Incorrect Answers — Review These
**Q[N]: [Question]**
- Your answer:
- Correct answer:
- Explanation:
- Review:

### Timing-specific message
[根据 pre-test / progress check / mastery check 给不同反馈]

### Recommended Next Steps
- [继续下一课 / 回看哪一节 / 重测 / 深入解释]

Step 6: 根据 timing 解释结果

If pre-test
  • 把成绩解释为“学习前基线”
  • 强调用户接下来应重点关注哪些主题
If during
  • 把成绩解释为“阶段性进度检查”
  • 明确哪些点已经掌握、哪些点要补
If after
  • 把成绩解释为“lesson mastery check”
  • 如果分数高,建议进入下一课
  • 如果分数一般,列出明确回看点

Files

What ships with it

2 files 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.
