rapid-domain-mastery: Instructions file for Codex

AGENTS.md

rapid-domain-mastery AGENTS.md is an instructions file for Codex, OpenCode from Emily2040/rapid-domain-mastery. It costs 340 tokens per session, scanned A, original, MIT.

Repository instructions for a reusable learning workflow called rapid-domain-mastery. The workflow helps an AI coding agent study a subject by auditing sources, mapping concepts, finding assumptions, planning prerequisites, and creating study or tutoring activities.

In plain words
What is it for?
Use it when maintaining this repository, improving the canonical skill, syncing mirrored versions, or checking that wrappers preserve the same learning workflow.
Why use it?
Changes made in one vendor-specific wrapper can drift away from the canonical workflow. These instructions identify the source of truth and keep adaptations aligned.

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

rapid-domain-mastery 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 9d 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

Repository Purpose

This repository packages a portable, source-heavy learning workflow for AI coding agents.

The core capability is rapid-domain-mastery, a reusable skill for:

  • corpus audit
  • field mapping
  • mental model extraction
  • debate mapping
  • assumption mining
  • prerequisite planning
  • diagnostic questioning
  • oral-exam tutoring
  • compressed study sprints

Source of truth

Treat these as canonical:

  • AGENTS.md
  • .agents/skills/rapid-domain-mastery/
  • support/support-matrix.json

All vendor-specific wrappers should stay semantically aligned with the canonical skill.

How to work in this repo

  1. Prefer editing the canonical skill under .agents/skills/rapid-domain-mastery/.
  2. After semantic changes, sync mirrored skill folders.
  3. Do not silently change behavior in one wrapper and not the others.
  4. Keep wrappers thin. They should adapt placement and host format, not rewrite the workflow.
  5. Keep support claims conservative. If vendor docs are unclear, mark the adapter as manual or compatibility-based.

Guidance for agents

When asked to improve this pack:

  • first update the canonical skill
  • then update references, templates, and validation scripts
  • then update wrappers
  • then update the support matrix

When asked whether a client is supported:

  • check VERIFIED-SUPPORT-MATRIX.md
  • distinguish official-docs vs directory-listed vs manual
  • never claim that one file layout works everywhere if the docs do not say that

Editing rule

Do not turn AGENTS.md into a giant workflow dump. Persistent guidance belongs here. Deep procedures belong in the skill.

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.
