A mentoring guide that helps an Engineering Manager think through leadership, product, team, or technical situations from an Engineering Director's perspective.

Use it when seeking advice or thinking through an unclear or difficult management situation.

It challenges vague assumptions and surfaces trade-offs, risks, and effects on people, systems, and the business.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00063	$0.00288
Opus 5.5	$0.00025	$0.00115
Sonnet 5.5	$0.00013	$0.00058
Haiku 4.5	$0.00006	$0.00029

Security

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 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.

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

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.
