qemu-board-modeling

qemu-board-modeling is a skill for Codex from processmission/oh-my-qemu. It costs 50 tokens per session (1,501 once invoked), scanned A, original, MIT.

A guide for modeling the virtual boards and machines that QEMU emulates. It covers processors, memory maps, boot paths, device connections, firmware data, and interrupts.

In plain words
What is it for?
Use it to define or inspect a QEMU board or system-on-chip model, verify memory and device layouts with qtest, and check representative device connections.
Why use it?
It helps check that an emulated machine is wired and mapped as intended before testing software on it.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Memory Poisoning · line 66
    Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.
    Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.

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-board-modeling 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 12d 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 Board and Machine Modeling

Audit workflow

For non-trivial workspace writes, use a stable .oh-my-qemu/<task-slug>/ directory and create only needed entries:

.oh-my-qemu/<task-slug>/
├── audit.md      # Baseline, scope, decisions, evidence, verification, and gaps
├── commands.md   # Redacted commands, working directories, and results
├── logs/         # Decisive build, test, runtime, or diagnostic logs
├── scripts/      # Temporary scripts, probes, parsers, and harnesses
└── output/       # Generated deliverables, dependencies, and non-QEMU binaries

Before changing source or mutable artifacts, record the workspace root, revision, git status --short, pre-existing changes, goal, scope, and acceptance checks in audit.md. Log exact redacted commands and results in commands.md; record revisions, configurations, tool versions, and hashes when they affect reproducibility. Separate observations from inferences and edit source only when requested.

Keep QEMU builds under source-root builds/build-<target>/; put third-party dependencies and non-QEMU binaries in task output/. Before writing audit artifacts or configuring QEMU in a Git worktree, add .agents/, .oh-my-qemu/, and builds/ to the repository-local file from git rev-parse --git-path info/exclude; preserve existing entries and avoid duplicates. Never stage or commit those directories. At handoff, verify them absent from git status --short. Report the task directory and unresolved gaps.

Workflow

  1. Freeze the board contract, allowed paths, and observable acceptance checks.
  2. Inspect the current machine, nearby boards, tests, boot ABI, and authoritative hardware sources before changing code.
  3. Work in small reviewable source-change rounds and record each round's paths, verification, review result, and gaps in audit.md.
  4. Build the affected target and add or extend board qtests for machine creation, memory-map probes, and representative IRQ/device wiring.
  5. Use boot or workload evidence only as a supplemental integration gate and state exactly what it proves.

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.
