📝 Walkthrough

Walkthrough

@KJLdefeated is added as a co-owner to multiple path rules in .github/CODEOWNERS, covering /rl_engine/kernels/**, its CUDA/PyTorch/Triton ops subdirectories, /csrc/**, and specific C++/CUDA source subpaths. The /rl_engine/kernels/ops/rocm/ rule is left unchanged.

CODEOWNERS Ownership Expansion

Layer / File(s)	Summary
Kernel and csrc ownership rules .github/CODEOWNERS	Adds @KJLdefeated to /rl_engine/kernels/** and its ops subdirectory rules (CUDA, PyTorch, Triton), and to /csrc/** and specific CUDA source subpaths, while preserving all existing owners and leaving /rl_engine/kernels/ops/rocm/ unchanged.

Poem

🐇 A new name joins the kernel crew,
Paths and rules get owners too.
CODEOWNERS grows, a wider net,
For every CUDA line we've set.
Hop along, the diff is small —
One reviewer added to all! 🌟

12-29: ⚡ Quick win

Approve CODEOWNERS path updates; flag auto-reviewer workflow gap.

The CODEOWNERS changes look correct and consistent:

• @KJLdefeated is properly added across all kernel paths (lines 12–21) and C++/CUDA source paths (lines 25–29).
• The intentional exclusion of /rl_engine/kernels/ops/rocm/ from the update (line 22) suggests the change scope is deliberate, likely reflecting @KJLdefeated's NVIDIA/CUDA expertise.
• Path specificity and override precedence are correct.

However, the .github/workflows/auto-reviewer.yml workflow hardcodes a reviewer list and does not consult CODEOWNERS. Even though @KJLdefeated is now a codeowner for kernel and C++/CUDA paths, they will not be automatically requested for reviews unless added to the workflow's candidateReviewers list. Consider updating auto-reviewer.yml line 16 to include 'KJLdefeated' to ensure review requests align with the new ownership rules.
