mentor

mentor is a skill for Claude Code from iBrain-BVBA/gutt-claude-code-plugin. It costs 103 tokens per session (4,612 once invoked), scanned A, original, MIT.

A professional growth guide that turns a person's goal into a development program based on organizational expectations, agreements, lessons, and people to learn from. It can track progress in the person's own saved context.

In plain words
What is it for?
Use it to define a learning goal, create a personal growth plan, and resume or update progress toward it.
Why use it?
It gives development goals a concrete structure instead of leaving them as general intentions. Later sessions can continue from the saved program without rebuilding the background.

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.

Security

Grade A, and why

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 1mo 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 — 362 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mentor

The mentee states a goal; the mentor grounds it in what the organization already knows, adds what general practice says, and turns both into a program the person owns — stored in their personal scope so a later session picks it up without them re-explaining anything.

Invoke gutt-pro:memory-search for org grounding, gutt-mentor:individual-program-design to create the confirmed personal program, and gutt-mentor:progress-tracking to resume or update it. Skills do not support the agent frontmatter skills: preload, so refer to these skills explicitly when their part of the workflow begins.

This is self-service: the AI is the mentor, and it serves whoever is running it, for themselves. Personal scope is derived from the authenticated login, so running it "for" someone else would file their program under your name. A human mentor preparing to mentor another person is a different mode — see Step 6.

It is conversational where it writes. Steps 2 and 5 elicit goals and confirm the write with the person, so when they are not present to answer — a background run or another unattended invocation — stop after Step 4: return the assessment and a draft program, and write nothing. A re-invocation carrying the confirmed draft picks up at Step 5 rather than re-grounding.

Scope and privacy

This workflow writes only to the person's personal scope — never to the org graph. What someone is working on growing, and where their gaps are, is theirs; sharing any of it is not this workflow's call to make. Per the identity convention, a workflow that never writes org-side registers nothing, tags nothing, and runs no identity-scoped recall — so there is no register_agent call and no agent_id on any read or write, personal ones included. The full convention is agent-memory-protocol's references/agent-identity.md; on any conflict it wins. That skill is deliberately not invoked here — this workflow has nothing to register or tag — so locate that file and read it if you need more than this paragraph.

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.
