oh-my-qemu: Instructions file for Codex

AGENTS.md

oh-my-qemu AGENTS.md is an instructions file for Codex, OpenCode from processmission/oh-my-qemu. It costs 734 tokens per session, scanned A, original, MIT.

Repository rules for developing and maintaining skills related to QEMU. They explain the boundary between local work and contributions to the official QEMU project.

In plain words
What is it for?
Use them when adding or changing QEMU skills, following the repository’s file layout, recording work, and deciding whether an action is only local or an upstream contribution.
Why use it?
They clarify which files, workflows, and Git actions are allowed, helping contributors keep each skill independent and avoid treating local changes as upstream submissions.

Instructions file for CodexOpenCode

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

This is processmission/oh-my-qemu's own configuration. It tells Codex and OpenCode how to work on oh-my-qemu 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 oh-my-qemu 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

oh-my-qemu 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.

QEMU Skill Repository Agent Guide

This file governs development of this repository. It is not installed into QEMU. Each installed skill must contain its own runtime rules and must not depend on or cite this file.

QEMU upstream boundary

QEMU's official GitLab and mailing lists are upstream channels. A patch becomes an upstream contribution only when it is sent to the mailing-list recipients selected through QEMU's MAINTAINERS.

  • Do not prepare or send agent-generated code or documentation for upstream submission. Follow QEMU's current docs/devel/code-provenance.rst.
  • Local branches, commits, patch files, pushes, and pull requests are not by themselves upstream contributions. Perform Git actions only when requested.
  • Research, debugging, analysis, local experiments, verification, and workflow guidance are allowed.

Changes to this repository follow its local Git policy.

Skill rules

  • Put skills in skills/<skill-name>/SKILL.md.
  • Keep each skill independently installable. Do not depend on another skill, repository file, installer behavior, or plugin hook.
  • Inside YAML frontmatter, put the Process Mission copyright and MIT SPDX comments immediately after the opening --- and before the data fields. Keep data fields to name and description.
  • Include matching agents/openai.yaml with quoted display_name, short_description, and $skill-name default_prompt.
  • Keep SKILL.md concise. Put long material in one-level references/, scripts/, or assets/.
  • Do not require checkpoint commits. Stage or commit only when requested.
  • Require explicit approval for external writes such as gh issue create.

Every skill must include the compact audit contract. For a non-trivial task that writes to QEMU, use only the needed entries under:

.oh-my-qemu/<task-slug>/
├── audit.md
├── commands.md
├── logs/
├── scripts/
└── output/

Keep temporary tooling in scripts/, generated or third-party artifacts in output/, and QEMU build output in a named source-root directory such as builds/build-aarch64/—never build/ or task output/. Change source files only when they are the requested deliverable.

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.
