minecraft-agent-skills: Instructions file for Codex

AGENTS.md

minecraft-agent-skills AGENTS.md is an instructions file for Codex, OpenCode from Jahrome907/minecraft-agent-skills. It costs 333 tokens per session, scanned A, original, MIT.

Repository rules for minecraft-agent-skills, a bundle of 13 skills that help AI assistants work with Minecraft projects and versions.

In plain words
What is it for?
Use it when editing Minecraft-related skills, syncing their Codex and Claude Code copies, checking JSON and documentation, or maintaining support for different Minecraft versions.
Why use it?
It identifies the canonical files and synchronization checks, which helps prevent mirrored skill copies from drifting apart. It also keeps version-specific Minecraft and Java guidance explicit.

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

This is Jahrome907/minecraft-agent-skills's own configuration. It tells Codex and OpenCode how to work on minecraft-agent-skills itself, so it is not a mod to install elsewhere.

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

minecraft-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 2d 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

minecraft-agent-skills

This repo is a skills bundle, not a Minecraft project. It ships 13 Minecraft skills and a dual-target Codex/Claude Code plugin.

Editing

  • Treat .agents/skills/ as canonical.
  • After canonical changes, run npm run sync:skills to refresh .codex/skills/, .claude/skills/, and plugins/minecraft-codex-skills/skills/.
  • Do not hand-edit mirrored skill trees.
  • Run npm run check before publishing changes.

Skill standards

  • Keep entrypoints focused on routing, version boundaries, and the requested outcome. Load substantial examples from local references only when relevant.

  • Preserve the user's project, version pins, and authorized scope. A sample workflow is not a requirement to migrate, publish, or add extra deliverables.

  • Verify changing APIs against primary documentation for the exact version. Distinguish static helper checks from compilation and in-game validation.

  • Target current stable Minecraft 26.x and Java 25 for new work. Preserve explicit legacy lanes for Minecraft 1.21.x on Java 21 and Forge 1.20.1 on Java 17 with ForgeGradle 6.

  • Keep platform-specific patterns clear and examples runnable.

  • Keep JSON valid and formatted with 2-space indentation.

  • Do not create cross-skill dependencies.

Repository boundaries

  • Do not run Minecraft, Gradle, or Paper server commands here.
  • Keep helper scripts self-contained inside the skill that uses them.
  • Do not add unstable Minecraft features or version guidance.

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.
