bevy-skills: Instructions file for Codex

AGENTS.md

bevy-skills AGENTS.md is an instructions file for Codex, OpenCode from chrisgliddon/bevy-skills. It costs 409 tokens per session, scanned A, original, MIT.

A collection of Agent Skills that teaches AI coding tools how to write Bevy 0.19 code, where Bevy is a Rust game engine. The guide explains how to use or edit these skills and how to validate their code examples.

In plain words
What is it for?
Use it when installing the skills correctly, editing their SKILL.md files, checking required metadata, or running the documented lint and Rust validation steps.
Why use it?
It prevents agents from treating the repository checkout as an automatically loaded skill and documents the checks needed to keep each skill compatible with Bevy 0.19.

Instructions file for CodexOpenCode

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

This is chrisgliddon/bevy-skills's own configuration. It tells Codex and OpenCode how to work on bevy-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 bevy-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

bevy-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 6d 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 · 28 lines

What it actually says

AGENTS.md

You are an AI coding agent that has landed in the bevy-skills repository.

What this repo is

A collection of Agent Skills (SKILL.md files) that teach AI agents how to write correct Bevy 0.19 code. Targets Claude Code, OpenCode, Cursor, Codex, Pi, and any other Agent Skills consumer.

If you are HERE TO USE the skills

You are in the wrong place. Skills load automatically from your agent's skill directory (e.g. ~/.claude/skills/). See README.md for install instructions, then close this checkout and let the skills load via your normal workflow.

If you are HERE TO EDIT the skills

Read CLAUDE.md. It is the authoritative editor guide. Highlights:

  • Every skill is a folder under skills/ with a SKILL.md (YAML frontmatter + body) and optional references/.
  • Frontmatter must pass scripts/lint-skills.py — name regex ^[a-z0-9]+(-[a-z0-9]+)*$ matching the directory, description 1–1024 chars, keys limited to name/description/license/compatibility/metadata.
  • Every code snippet must cargo check against bevy = "0.19" in the companion bevy-skills-tester crate (not in this repo — see CLAUDE.md).
  • Pin Bevy 0.19 explicitly in every current skill's description. Historical migration skills pin their own target with metadata.target_version; no guidance is unversioned.
  • Use dex for persistent project work. Repository-local tasks live in .dex/tasks.jsonl and automatically sync root tasks to GitHub Issues.

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.
