3dgs-code-reviewer

3dgs-code-reviewer is a skill for Claude Code from jaccen/Awesome-Gaussian-Skills. It costs 110 tokens per session (2,715 once invoked), scanned A, original, Apache-2.0.

A code-review guide for implementations of 3D Gaussian Splatting, a method for rendering 3D scenes from collections of small translucent shapes. It focuses on rendering code, CUDA GPU kernels, training loops, and loss calculations.

In plain words
What is it for?
Use it to review rasterisation order, transparency calculations, tile-based rendering, Gaussian bounds, background handling, loss functions, and training pipelines.
Why use it?
It helps detect correctness errors, performance problems, and rendering mistakes that can produce wrong images or inefficient training.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

3dgs-code-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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 (108+ known bug 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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

3dgs-code-reviewer is a skill published in the GitHub repository jaccen/Awesome-Gaussian-Skills (150 stars, last pushed 6d ago), licensed Apache-2.0. It adds 110 tokens to every session and 2,715 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
