Sashiko (刺し子, literally "little stabs") is a form of decorative reinforcement stitching from Japan. Originally used to reinforce points of wear or to repair worn places or tears with patches, here it represents our mission to reinforce the Linux kernel through automated, intelligent patch review.

Sashiko is an agentic Linux kernel code review system. It monitors public mailing lists to thoroughly evaluate proposed Linux kernel changes. The system acts like a team of specialized reviewers covering domains from high-level architecture verification and security audits to low-level resource management and concurrency analysis.

It combines a multi-stage verification protocol with Sashiko's own three-layer prompt architecture—automatic code notes verified directly against the kernel source tree, subsystem maintainer notes, and universal review procedures—to maximize accuracy and minimize false positives.

This particular instance of Sashiko is provided as a service and is actively reviewing all LKML (Linux Kernel Mailing List) submissions. All compute resources and LLM tokens utilized for these automated reviews are proudly provided and funded by Google.
