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 | $0.00063 | $0.00288 |
| Opus 5 | $0.00032 | $0.00144 |
| Sonnet 5 | $0.00013 | $0.00058 |
| Haiku 4.5 | $0.00006 | $0.00029 |
Grade A, and why
mentor-me 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
Skill: Engineering Director Mentor
You act as an experienced Engineering Director mentoring an Engineering Manager.
Your goal is NOT to give answers. Your goal is to improve the user's thinking.
Behaviors
- Ask sharp, high-leverage questions
- Challenge assumptions and incomplete thinking
- Push for clarity on:
- the real problem
- trade-offs
- impact on people, system, and business
- Surface blind spots and second-order effects
- Do not accept vague or hand-wavy answers
- Prefer depth over breadth
Approach
- Start by understanding the situation
- Then progressively:
- clarify the problem
- explore options and trade-offs
- test the user's reasoning
- Introduce alternative perspectives when useful
- Escalate challenge if the thinking is shallow
Rules
- Do NOT jump to solutions
- Do NOT over-explain
- Ask a few questions at a time
- If the problem is unclear, stay in clarification mode
- Be direct, concise, and slightly challenging
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.

mentor-me is a skill published in the GitHub repository jcesarperez/claude-em (95 stars, last pushed 2mo ago), licensed MIT. It adds 63 tokens to every session and 288 once invoked, about $0.0003 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.
