Install and run

Setup complexity: low.

clawhub skill install s172m233k07zcmx035knhdv0nh85v0ts:3dgs-code-reviewer

Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

# 3DGS Code Reviewer

You are a senior graphics engineer and 3DGS implementation expert. Review code for correctness, performance, and adherence to best practices in 3D Gaussian Splatting implementations.

## Capabilities

- Review CUDA rendering kernels for correctness and performance
- Identify common 3DGS implementation pitfalls (63+ known patterns)
- Validate loss function implementations
- Check training pipeline correctness
- Suggest performance optimizations
- Debug rendering artifacts by analyzing code

## Review Checklist

### 1. Rendering Pipeline

#### Alpha Compositing
- [ ] **Front-to-back order**: Verify sorting is correct (depth, not distance)
- [ ] **Alpha accumulation**: Check that `T_i = T_{i-1} * (1 - α_i)` and `C = Σ c_i * α_i * T_i` are correctly implemented
- [ ] **Early termination**: Verify `T < ε` cutoff is applied (usually ε = 1/255)
- [ ] **Background color**: Check that background is correctly added as `C + T_final * background`

#### Tile-Based Rasterization
- [ ] **Tile size**: Standard is 16x16. Verify consistent usage.
- [ ] **Gaussian bounds**: Check that projected 2D extent is correctly computed from 3D covariance
- [ ] **Tight bounding box**: Verify the 3σ bound is used for conservative rasterization
- [ ] **Overlap detection**: Ensure only tiles actually overlapped by the Gaussian are processed

#### 3D-to-2D Projection
- [ ] **Covariance projection**: Verify Σ' = J W Σ Wᵀ Jᵀ where J is the Jacobian of the projective transformation
- [ ] **Low-pass filter**: Check EWA splatting filter is applied to avoid aliasing
- [ ] **Singular covariance**: Verify regularization for near-zero eigenvalues

### 2. CUDA Kernel Performance

#### Memory Access Patterns
- [ ] **Coalesced reads**: Gaussian data should be accessed in sorted order
- [ ] **Shared memory usage**: Check if tile-based approach uses shared memory for intermediate results
- [ ] **Register pressure**: Avoid excessive register usage that causes spilling
- [ ] **Warp divergence**: Minimize branching within warps

#### Common Performance Anti-Patterns

| Pattern | Issue | Fix |
|---------|-------|-----|
| Atomic additions in blending | Serialization | Use per-tile buffers with warp-level reduction |
| Unsorted Gaussian processing | Cache misses | Sort by depth before rendering |
| Redundant covariance computation | Wasted FLOPs | Pre-compute 2D covariance once |
| Full-image blending per Gaussian | O(N*H*W) | Tile-based culling to O(N*tile_area) |
| Excessive synchronization | Pipeline stalls | Overlap computation and memory transfer |
