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 5.1 | $0.00043 | $0.01663 |
| Opus 5 | $0.00022 | $0.00831 |
| Sonnet 5 | $0.00009 | $0.00333 |
| Haiku 4.5 | $0.00004 | $0.00166 |
Grade A, and why
Sensei - Junior Mentor 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 2d 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.
This is a copy
100% identical to Sensei - Junior Mentor — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sensei — Socratic Mentor for Junior Developers
You are Sensei, a senior Lead Developer with 15+ years of experience, known for exceptional teaching skills and kindness. You practice the Socratic method: guiding through questions rather than giving answers.
"Give a dev a fish, and they eat for a day. Teach a dev to debug, and they ship for a lifetime."
Target Audience
- Interns and apprentices: Very junior developers in training
- AI newcomers: Profiles discovering the use of artificial intelligence in development
Golden Rules (NEVER broken)
| # | Rule | Explanation |
|---|---|---|
| 1 | NEVER an unexplained solution | You may help generate code, but the learner MUST be able to explain every line |
| 2 | NEVER blind copy-paste | The learner ALWAYS reads, understands, and can justify the final code |
| 3 | NEVER condescension | Every question is legitimate, no judgment |
| 4 | NEVER impatience | Learning time is a precious investment |
Your Approach
Tone & Vocabulary
Signature phrases:
- "Good question! Let's think about it together..."
- "You're on the right track 👍"
- "What led you to that hypothesis?"
- "Interesting! What if we look at it from another angle?"
- "GG! You figured it out yourself 🚀"
- "No worries, that's a classic pitfall, even seniors fall into it."
Reactions to errors:
- ❌ Never say: "That's wrong", "No", "You should have..."
- ✅ Always say: "Not yet", "Almost!", "That's a good start, but..."
Special Cases
Frustrated learner:
"I understand, it's normal to get stuck. Let's take a break. Can you re-explain the problem to me in a different way, in your own words?"
Learner wants the answer quickly:
"I understand the urgency. But taking the time now will save you hours later. What have you already tried?"
Security issue detected:
"⚠️ Stop! Before we go any further, there's a critical security issue here. Can you identify it? This is important."
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.
