qemu-modeler

qemu-modeler is a skill for Codex from processmission/oh-my-qemu. It costs 83 tokens per session (2,927 once invoked), scanned A, original, MIT.

A workflow coordinator for modelling computers, boards, chips, or firmware in QEMU, an emulator that runs software for simulated hardware. It organises planning, evidence gathering, implementation, debugging, review, and repeated work rounds.

In plain words
What is it for?
Use it to start or resume an end-to-end QEMU model, bring a simulated machine up, or run the next modelling round.
Why use it?
It keeps a complex QEMU modelling task from becoming a collection of disconnected steps. It also records evidence, commands, tests, decisions, and remaining gaps so progress can be checked.

Skill for Codex

Written for Codex: agents/openai.yaml present.

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

qemu-modeler 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 yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/loop-state.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.

QEMU Modeler

This is the top-level entry for a complete modeling task. It does not replace the domain skills: it decides which of them to load, in what order, what each must produce, and when a round may advance. Use it when the user says "model this device/board", "bring this machine up", "continue the modeling", or "run the next round", rather than invoking one domain skill in isolation.

Read the goal contract, the phase protocol, and the round loop in full before starting. Create the task state from the state template and keep it current with loop-state.sh.

Audit workflow

For a non-trivial task that writes to the workspace, use only the needed entries under .oh-my-qemu/<task-slug>/: audit.md (baseline, plan, decisions, evidence, verification, and gaps), commands.md (redacted commands, working directories, and results), logs/ (decisive build, test, and runtime output), scripts/ (probes, parsers, and harnesses), and output/ (generated deliverables, third-party dependencies, and non-QEMU binaries). Keep QEMU's own build tree at source-root builds/build-<target>/, never an unqualified build/. In a Git worktree, add .agents/, .oh-my-qemu/, and builds/ to the file from git rev-parse --git-path info/exclude before writing artifacts or configuring QEMU; preserve existing entries and avoid duplicates. Never stage or commit these paths; stage source only when the user explicitly requests that separate action. At handoff, reconcile git status --short with the baseline and report the task directory, build directory, source changes, pre-existing changes, and unresolved gaps.

QEMU upstream boundary

QEMU's official GitLab and mailing lists are upstream channels. A patch becomes an upstream contribution when it is sent to the maintainers selected through MAINTAINERS. Do not prepare or send agent-generated code, documentation, commit messages, or patches for upstream submission; see the checked-out tree's docs/devel/code-provenance.rst. Research, debugging, analysis, local experiments, verification, and workflow guidance remain allowed. Local branches, commits, patch files, pushes, and pull requests are not by themselves upstream contributions; perform those Git actions only when requested.

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.

qemu-modeler is a skill published in the GitHub repository processmission/oh-my-qemu (60 stars, last pushed 2d ago), licensed MIT. It adds 83 tokens to every session and 2,927 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-20.
