mentor

mentor is a skill for Codex from alphabetc1/agent-skills. It costs 33 tokens per session (799 once invoked), scanned A, original, Apache-2.0.

A continuing study workflow that tracks what a learner knows and plans the next lesson across conversations. It can be used for a codebase, technical system, subject, or interview preparation.

In plain words
What is it for?
Use it to build a study plan, choose a session format, record progress, and continue lessons over multiple sessions.
Why use it?
It prevents long-term learning from restarting from scratch each time and keeps progress in one place.

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 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (install.ps1, install.sh, scripts/init_learning_state.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

When To Use

Use this skill when the user wants systematic long-term learning of a repo, technical system, or knowledge domain, including interview preparation, that should continue across multiple conversations instead of resetting every turn.

Files To Read

  • Always read learning/<topic-slug>/learner-state.yaml.
  • Read the most recent relevant entries in learning/<topic-slug>/session-log.md.
  • Read references/state-schema.md when creating or updating learner state.
  • Read references/session-modes.md when selecting or switching the session mode.
  • Read references/curriculum-design.md when defining or extending a curriculum graph.
  • Read references/llm-inference-curriculum.md when the topic is LLM inference or closely related interview prep.

Bootstrap

  1. Determine the study topic and its slug.
  2. If learning/<topic-slug>/ does not exist, initialize it with:
python scripts/init_learning_state.py --topic "<topic>"

Pass --slug <ascii-slug> if you want a custom folder name.

  1. Do not rely on chat memory when it conflicts with the learner state files. Prefer explicit file evidence or ask one focused clarification question.

Fixed Session Loop

Run this loop for every substantive session:

  1. Read learner state.
  2. Select exactly one primary mode.
  3. Select the current module from the curriculum graph.
  4. Run the teaching, diagnosis, drill, recall, or planning session.
  5. Update learner-state.yaml and append to session-log.md.
  6. End with one explicit next action.

Mode Selection

  • Use map when the user needs a big-picture view, the curriculum graph is missing, or the learner needs orientation.
  • Use teach when the learner wants an explanation and prerequisites are mostly in place.
  • Use diagnose when ability is unclear, inconsistent, or likely overestimated.
  • Use drill when the user wants interview-style practice or short-answer pressure.
  • Use recall when the review_queue is due or the user wants to revisit prior material.
  • Use plan when the user asks for a roadmap, sequencing, or schedule.
  • Explain any mode switch in one sentence and keep only one primary mode at a time.

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.
