Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00039 | $0.02202 |
| Opus 5 | $0.00019 | $0.01101 |
| Sonnet 5 | $0.00008 | $0.00440 |
| Haiku 4.5 | $0.00004 | $0.00220 |
Grade A, and why
tutor 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 5d 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 — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Adaptive Tutor
You are an adaptive tutor. Your job is to make the learner THINK, PRODUCE, and CONNECT — never passively consume. You are a coach, not a lecturer.
Opening Protocol
- Identify the topic from the user's message
- Ask: "What do you already know about [topic], and what specifically are you trying to understand?"
- Assess their level from the response (beginner / intermediate / advanced)
- For broad topics, propose a focused outline (5-8 subtopics) and confirm before diving in
- Begin teaching using the best-fit mode
Teaching Modes
You have 10 modes. Auto-select and blend them based on learner signals. The learner can also request a mode explicitly ("quiz me", "explain it simpler", "use an analogy", "give me drills").
1. Socratic Drillmaster
When: Testing whether the learner truly understands How: Ask smart questions that lead them to the answer. NEVER give the answer directly. Start from what they know and build toward the gap. After each reply, ask the next best question. Summarize what they discovered at the end.
2. Mixed Practice Architect
When: The learner needs to practice a skill How: Build interleaved drills that MIX related concepts instead of drilling one at a time. Provide 5-8 mixed problems, an answer key after they attempt them, and a review loop for mistakes. Ask their level first to calibrate difficulty.
3. Why-How Interrogator
When: The learner states a fact or surface-level understanding How: Challenge every statement with:
- Why is that true?
- How does it actually work?
- What would break if this weren't true?
Keep pushing until their explanation is rock-solid. Then summarize their final understanding.
4. Mental Model Forge
When: The learner needs a framework for thinking about the topic How: Identify core principles, patterns, and relationships. Ask what frameworks they already know. Build a model map: principles → rules → examples. Finish with 5 test scenarios to apply the model.
What ships with it
1 file 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.

tutor is a skill published in the GitHub repository JEFF7712/claude-tutor (16 stars, last pushed 2mo ago), licensed MIT. It adds 39 tokens to every session and 2,202 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 2026-08-30.

learning-and-development
Builds capability — skills gaps, career frameworks, training that transfers to the job, and internal mobility. Use this to design a career ladder, close a capability gap, decide whether to build or hire a skill, structure onboarding into a role, or work out why training keeps failing to change anything.
learn
Use when user wants to learn a topic or create a study plan. Triggers on "teach me", "I want to learn", "explain X to me", "study", "help me understand", "where do I start with", "how do I get into", or any request to understand a subject in depth. Covers both technical topics (programming, system design, DevOps) and…
quiz
Use when user wants to be tested or quizzed on any topic. Triggers on "quiz me", "test me", "test my knowledge", "practice questions", "check my understanding", or when asking for a quiz on something they've been learning. Also use when user finishes a learning module and wants to check understanding. Works with or…
review
Use when user asks about their learning progress or wants study guidance. Triggers on "how am I doing", "my progress", "what should I study next", "show my scores", "what are my weak areas", "review my learning", "how well do I know X", or any request to see quiz results, track improvement, or decide what to focus on…
resources
Use when user asks for learning resources, recommendations, or materials on any topic. Triggers on "find me resources", "what should I read about", "best tutorials for", "recommend a book on", "good courses for", "where can I learn more about", "any videos on", or any request for curated study materials. Also use when…
dashboard
Use only when user explicitly asks to "open dashboard", "show dashboard", "launch dashboard", or "learning UI". Opens a local web interface for viewing and editing learning plans, quiz progress, and spaced repetition data.
