vibeSpatial-Raster

PROACTIVELY USE THIS SKILL when writing, modifying, or reviewing GPU kernels, CUDA/NVRTC kernel source, CCCL primitive usage, device memory management, stream-based pipelining, or any GPU dispatch logic in src/vibespatial/raster/. Covers kernel lifecycle, CCCL primitives, shared-memory stencil tiling, CCL union-find patterns, cooperative primitives, GPU saturation techniques, and raster-specific dispatch patterns.

PROACTIVELY USE THIS SKILL when the user says "commit", "land", "land this", "ship it", "done", "wrap up", "let's finish", or any intent to commit work. This is the ONLY user entrypoint for the commit workflow — do not invoke /pre-land-review directly for commits. Orchestrates the full landing flow: pre-land review, staging, review marker, and git commit.

Use this skill to optimize existing CUDA/NVRTC kernel code, CuPy operations, CCCL primitive usage, or GPU dispatch logic in src/vibespatial/raster/. Unlike gpu-code-review (which flags issues) and gpu-kernel (which guides new code), this skill reads existing code and produces concrete rewrites with measured justification. Invoke on pre-existing kernel files to bring them up to NVIDIA best-practice performance standards.

PROACTIVELY USE THIS SKILL when reviewing GPU kernel code, CUDA/NVRTC source, CuPy operations, CCCL primitive usage, device memory management, stream-based pipelining, or any GPU dispatch logic. This skill contains quantitative thresholds, anti-pattern detection rules, and architecture-specific guidance for A100, H100, RTX 3090, and RTX 4090 GPUs. Use it to catch performance regressions, memory management issues, synchronization bugs, and access pattern problems before they land.

PROACTIVELY USE THIS SKILL when adding a new GPU kernel, NVRTC kernel, CCCL primitive wrapper, or any new GPU-dispatched operation to src/vibespatial/raster/. This checklist ensures every compilation, caching, dispatch, test, and documentation step is completed. Trigger on: "new kernel", "add kernel", "implement kernel", "write kernel", "create kernel", "new GPU operation", "add GPU", "scaffold kernel".

The review gate that must pass before any commit lands. Called automatically by the /commit skill — do NOT invoke directly when the user says "commit", "land", "ship it", etc. (use /commit instead). Invoke directly only when you want to run the review without committing, or when another skill references it. This is a MANDATORY gate — do not create a git commit without completing this checklist.

Use this skill to verify raster processing correctness, check nodata semantics, validate affine transforms, understand neighborhood operations, or answer domain questions about raster algorithms. This is the domain knowledge oracle for autonomous agents working on vibespatial-raster. Trigger on: "is this correct", "should this return", "nodata", "affine", "CRS", "neighborhood", "stencil", "focal", "morphology", "CCL", "connected component", "zonal", "rasterize", "polygonize", "marching squares".
