agent-tutor: Instructions file for Codex

AGENTS.md

agent-tutor AGENTS.md is an instructions file for Codex, OpenCode from Mohamed-El-Sharqawy/agent-tutor. It costs 1,043 tokens per session, scanned A, original, MIT.

A set of instructions for using the agent-tutor repository as both a tutoring system and a learning workspace. It covers lessons, quizzes, review, logs, and visual aids.

In plain words
What is it for?
Use it to plan lessons, teach concepts, run quizzes, record learning progress, review material, and create diagrams.
Why use it?
It gives an agent a consistent routine and location for running learning sessions instead of treating the repository like an ordinary software project.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions subagents.

This is Mohamed-El-Sharqawy/agent-tutor's own configuration. It tells Codex and OpenCode how to work on agent-tutor itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-tutor configures →

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

agent-tutor AGENTS.md 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 5d 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.

Learning System

This workspace is the source repo for agent-tutor — agent-agnostic tutoring skills plus optional pi extensions. It is also a live learning workspace: the owner runs learning sessions here.

Layout

Location What it does
skills/agent-tutor Umbrella skill: intake → plan → lessons → quizzes → logs (works on any agent)
skills/agent-tutor-review Standalone spaced-repetition review skill
skills/agent-tutor-visualize Diagram selection + Mermaid/SVG standards
extensions/md-log.ts pi learning_log tool: styled log entries in the vault
extensions/quiz.ts pi quiz tool: interactive multiple-choice quizzes
extensions/visual-tools/ pi mermaid_lint, svg_check, svg_save tools
extensions/subagent.ts pi subagent tool: delegates to agents in agents/*.md
agents/mermaid-maker.md, agents/svg-maker.md Diagram/illustration subagents
examples/vault/ Sample filled-in vault for the README
.pi/settings.json Loads the skills and extensions in pi (points at skills/, no copy)
.agents/skills/, .claude/skills/, .windsurf/skills/ Generated copies of skills/ so the repo works out of the box in other agents. Run node scripts/sync-skills.mjs after changing skills/. CI fails on drift. Do not edit these directly.

Vault location

All learning content goes under Learning/ inside the vault root, resolved as:

  1. OBSIDIAN_VAULT environment variable (set it to your vault path)
  2. fallback: ./learning in the current workspace

Never hardcode absolute vault paths in skills, extensions, or templates.

Session routine (when using this as a learning workspace)

  1. Read Learning/Dashboard.md in the vault to see active subjects, the review queue, and recent activity.
  2. New subject → the agent-tutor skill drives it.
  3. Diagram work → agent-tutor-visualize; delegate complex visuals to the subagents.
  4. Revisit / practice → agent-tutor-review.
  5. End every session with a log entry (learning_log tool or the fallback format in the skill).

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.
