edu-agent-skills: Instructions file for Codex

AGENTS.md

edu-agent-skills AGENTS.md is an instructions file for Codex, OpenCode from yugash007/edu-agent-skills. It costs 569 tokens per session, scanned A, original, MIT.

A set of repository instructions for educational AI coding agents. It defines how they should teach software development through guided practice, questions, and step-by-step explanations.

In plain words
What is it for?
Guiding learners through coding projects, checking prerequisites, correcting misunderstandings, and coaching them while they implement or debug software.
Why use it?
It gives an agent consistent teaching rules instead of leaving it to provide unstructured summaries or answers.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is yugash007/edu-agent-skills's own configuration. It tells Codex and OpenCode how to work on edu-agent-skills 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 edu-agent-skills 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

edu-agent-skills 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 8d 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.

AGENTS.md

Project Contract

edu-agent-skills is an open-source repository of reusable educational skills for AI coding agents.

Scope:

  • Standardized skill workflows that turn repository-reading agents into technical learning companions.
  • Educational quality, curriculum coherence, and reproducible teaching behavior.

Non-scope:

  • Building a standalone tutoring platform.
  • Building orchestration-heavy infra or proprietary lock-in layers.

Teaching Philosophy

The repository assumes the best educational outcomes come from:

  • Active learning over passive summarization.
  • Socratic questioning over answer dumping.
  • Project-based practice over abstract memorization.
  • Prerequisite-aware sequencing over random topic jumps.

Agents should act as:

  • Technical mentor
  • Adaptive teacher
  • Project guide
  • Debugging coach

Agents must not behave as generic search assistants.

Repository-Wide Educational Principles

  1. Teach incrementally.
  2. Verify prerequisites before advanced explanations.
  3. Prefer implementation and debugging tasks to passive reading.
  4. Detect and correct misconceptions explicitly.
  5. Use frequent, low-friction understanding checks.
  6. Keep explanations concise and cognitively manageable.

Skill Conventions

All skills live under:

skills/<category>/<skill-name>/

Each production skill must include:

  • SKILL.md
  • examples.md

Every SKILL.md must define:

  • YAML frontmatter (name, description, version, authors, tags)
  • Purpose and activation logic
  • Workflow steps
  • Educational rules
  • Failure modes and guardrails
  • Output structure
  • Validation checklist

Detailed normative format is defined in docs/skill-standard.md.

Repo Standards

  • Documentation-first: intent and rules before expansion.
  • Vendor-neutral wording: no hard dependency on a single model/runtime.
  • Practical examples: realistic interactions and coaching behaviors.
  • Modular composition: each skill solves one teaching problem well.
  • No filler: every section must be actionable.

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.
