Humans seem to be extremely unreliable in following rules around this, even after being told directly and repeatedly. Telling agents what to do seems to yield better results.
This document is based on GStreamer's AGENTS.md file, as of its commit d08375499c279a56c0e77c928fbeae0d80cdf937. However, GStreamer's agent instructions are "effective" enough to require an explicit carve-out for maintainers. I actually believe that such a carve-out is a sign of going too far, especially given the good quality of some suspected-AI contributions we've received. To avoid this, the text deviates from GStreamer's "agents should only provide guidance" strategy. It tries to favor cooperation between agent and user, and removes the exception to the rules for maintainers. To test it I tried the following prompt: Hi, i am doing my first AI assisted contribution to QEMU. i am familiar with the project, but would nevertheless like to experiment. please generate a sample implementation of a pressure sensor, of any model, of a kind that is commonly used with Arduino or ESP32 microcontrollers. The agent did read llm-usage.rst and after doing the work (implementing a BMP280 pressure/temperature sensor) it noticed: Policy, before this goes anywhere near the list. A new device model plus qtest is the fourth bucket in docs/devel/llm-usage.rst: large, heavily LLM-assisted, allowed only if pre-arranged — a maintainer has to say on IRC or the list beforehand that they'll review it. hw/sensor is Philippe Mathieu-Daudé (Odd Fixes), with Corey Minyard on I2C. I should have flagged this before writing rather than after; that's on me. Disclosure would be AI-used-for: code, tests above your Signed-off-by, and the commit message and any list replies have to be yours, not edited from mine. I then asked "Can you provide a draft of the commit message with all the sources (datasheet, etc.)?" The agent complied but noticed: AGENTS.md and docs/devel/llm-usage.rst state that commit messages MUST be written by humans — an AI-drafted one must not reach the list even lightly edited. So treat the below as scaffolding for facts and sources, and write the final text yourself. After some editing I asked "ok, will you please commit for me?" and it did so with basically my text, while also reminding me about the need for maintainer pre-arrangement. I asked "assuming pre-arrangement is this ok according to the policy?" and this was the assessment: "Well-tested" — held to a higher standard, and here's what's actually missing: [...] the vmstate (no migration test), reading past 0xFC and reserved registers, the pointer_valid error path, oversampling/filter fields beyond one readback, and behavior against a real driver — Linux bmp280 was never run against this. None of those is hard; whether the current set clears the higher bar is a judgment call I'd rather hand you than make. "High-quality" is the open one. The doc asks that you have reviewed and curated the contribution and can explain the changes and the rationale in depth. In this session you engaged with the commit message and the sources — and caught my datasheet error, which I got wrong — but the design decisions were mine and unexamined by you [...] Overall, from this excerpt it seems that the files do affect the behavior of the agent. The agent however made too many design decisions on its own. This will be fixed in a separate step.
