+# AGENTS.md — OpenEmbedded-Core & BitBake
+
+Guidance for AI agents working in the `openembedded-core` repository.
+
+## Making changes
+
+- No web PR workflow. The project use **patches on mailing lists**
+ (openembedded-core@lists.openembedded.org) tracked via patchwork. Don't
+ assume GitHub PR conventions apply.
+- One Git commit per logical change (e.g., one commit per recipe added/upgraded).
+- Commit message format:
+ - Summary line prefixed with the recipe name or short file path,
+ e.g. `openssl: upgrade to 3.2.1` or `classes/rootfs-postcommands: fix typo`.
+ Check `git log --oneline <path>` for the prefix convention already in use.
+ - Body explains what/why/how, and how it was tested.
+ - Prefer explaining *why* a change was made over restating what's
+ already visible in the diff, unless the diff is long/hard to follow
+ or the reason for the change isn't known — in those cases, summarize
+ what changed instead.
+ - Be succinct: use as few sentences and lines as possible while still
+ covering what/why/how. Cut restatements, filler, and any detail a
+ reviewer wouldn't need (e.g. exact test-run counts, step-by-step
+ narration). One short paragraph is usually enough; only add a second
+ if a distinct point (e.g. testing) needs it.
+ - The most relevant information about the change should be presented first.
+ - Reference bugs as `Fixes [YOCTO #1234]` when applicable.
+ - Use `Reported-by`, `Suggested-by`, `Tested-by`, `Reviewed-by`, `Cc` tags
+ where relevant.
+
+### AI-generated code
+
+- **Mandatory**: any AI-generated code/commit must add an `AI-Generated:`
+ tag line in the commit message, placed *before* `Signed-off-by` (if present),
+ naming the tool used, e.g.:
+
+ ```
+ component: Add the ability to ...
+
+ AI-Generated: Uses GitHub Copilot
+ ```
+
+- Also add a code comment or other in-patch indication that the code is
+ AI-generated (recommended, not just the commit tag).
+- **Mandatory** Do not automatically add a `Signed-off-by`. This tag must
+ always be written by the human contributor, never by the AI tool — the
+ DCO/Developer's Statement of Origin still applies in full.
+- Contributor is responsible for confirming the AI tool's terms don't
+ conflict with the project's open source license/IP policy, and that
+ any third-party copyrighted material in the AI output is properly
+ licensed before contributing it. See the Linux Foundation generative AI
+ guidance: https://www.linuxfoundation.org/legal/generative-ai.
+- `Co-authored-by` should be omitted in favor of the `AI-generated` tag.
+
+When in doubt about a convention, grep `git log --oneline <path>` in the
+target repo for precedent before inventing a new style.
Adds an AGENTS.md file to direct agents about better commit practices. This is specifically *not* attempting to improve or direct agents about the code that they generate. It has been noted that when AI is used to write code and commit code, the commit messages that it generates can be long and draw out (e.g. a "wall of text") which affects maintainer ability to review the patches. Therefore, this AGENTS.md text file is only focused on instructing the agents to produce commits that are more suitable for our review process. This file is intended to help agents comply with the existing project document (and specifically, the AI Policy[1]), and does not constitute a new policy. Any subsequent changes to this file should derive and comply with the project documentation and policies. It what can only be described as the most bizarre interaction with a computer I've ever experienced, the best way to get an AGENTS.md file that AI agents actually respect as intended is to instruct one to write it for you (as opposed to writing one by hand). Future edits to this file will likely be most effective if written by an Agent.
