A patch adding AGENTS.md to the Linux kernel tree draws objections in review

Sources: primary, report, discussion
Summary: Sasha Levin posted the patch on 2026-09-24, one line adding a top-level AGENTS.md symlink to README, which already points at Documentation/process/coding-assistants.rst. The commit message gives the test that motivated it. Asked to rename the Makefile release string, one agent without the file added a Signed-off-by for the human submitter on its own and used its own attribution trailer instead of Assisted-by, and a second added no attribution, while with the symlink in place both used Assisted-by and neither forged a sign-off.
Comments: The thread is unresolved as of 2026-09-26, and three replies read in full object to the patch. Theodore Tso objects on token cost. Bradley Morgan replies NAK and proposes agent memories and a MEMORY.md file instead. Antheas Kapenekakis, replying on 2026-09-26, objects that tracking the file in mainline dirties trees that carry a local one, and proposes a gitignore entry plus a template.
Why it matters: Only the human submitter can certify the Developer Certificate of Origin, so an agent fabricating a Signed-off-by is the concrete failure the patch is meant to prevent.
Follow-up: Track whether the symlink is merged, replaced by a gitignore entry and template, or dropped.
