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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.01960 |
| Opus 5 | $0.00046 | $0.00980 |
| Sonnet 5 | $0.00018 | $0.00392 |
| Haiku 4.5 | $0.00009 | $0.00196 |
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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lesson Quiz
Interactive quiz that tests understanding of a specific Claude Code lesson with 8-10 questions, provides per-question feedback, and identifies areas to review.
Instructions
Step 1: Determine the Lesson
If the user provided a lesson as an argument (e.g., /lesson-quiz hooks or /lesson-quiz 03), map it to the lesson directory:
Lesson mapping:
01,slash-commands,commands→ 01-slash-commands02,memory→ 02-memory03,skills→ 03-skills04,subagents,agents→ 04-subagents05,mcp→ 05-mcp06,hooks→ 06-hooks07,plugins→ 07-plugins08,checkpoints,checkpoint→ 08-checkpoints09,advanced,advanced-features→ 09-advanced-features10,cli→ 10-cli
If no argument was provided, present a selection prompt using AskUserQuestion:
Question 1 (header: "Lesson"): "Which lesson do you want to quiz on?" Options:
- "Slash Commands (01)" — Custom commands, skills, frontmatter, arguments
- "Memory (02)" — CLAUDE.md, memory hierarchy, rules, auto memory
- "Skills (03)" — Progressive disclosure, auto-invocation, SKILL.md
- "Subagents (04)" — Task delegation, agent config, isolation
Question 2 (header: "Lesson"): "Which lesson do you want to quiz on? (continued)" Options:
- "MCP (05)" — External integration, transport, servers, tool search
- "Hooks (06)" — Event automation, PreToolUse, exit codes, JSON I/O
- "Plugins (07)" — Bundled solutions, marketplace, plugin.json
- "More lessons..." — Checkpoints, Advanced Features, CLI
If "More lessons..." is selected, present:
Question 3 (header: "Lesson"): "Select your lesson:" Options:
- "Checkpoints (08)" — Rewind, restore, safe experimentation
- "Advanced Features (09)" — Planning, permissions, print mode, thinking
- "CLI Reference (10)" — Flags, output formats, scripting, piping
Step 2: Read the Lesson Content
Read the lesson README.md file to refresh context:
- Read file:
<lesson-directory>/README.md
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.
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.

lesson-quiz is a skill published in the GitHub repository eitelcj/Claude-Weekend (2 stars, last pushed 5mo ago), licensed MIT. It adds 91 tokens to every session and 1,960 once invoked, about $0.0005 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.

hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".

Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context.
