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(NHW)	Tile-based culling to O(N*tile_area)
Excessive synchronization	Pipeline stalls	Overlap computation and memory transfer

3. Training Pipeline

Adaptive Density Control (ADC)

Clone threshold: Verify gradient-based clone decision (grad threshold)
Split threshold: Verify position-based split decision (scale threshold)
Prune: Check opacity pruning threshold (typically α < 0.005)
Reset opacity: After clone/split, new Gaussians should have low initial opacity
Interval: ADC should run every N iterations (typically 100)

Loss Function

L1 loss: Standard pixel-wise L1 between rendered and ground truth
D-SSIM loss: Structural dissimilarity on patches (window size typically 11)
Lambda balance: Typical λ_DSSIM = 0.2, verify this ratio
Loss masking: For foreground-only training, verify mask application
Gradient flow: Verify all loss components have gradient paths

Training Schedule

Learning rate: Official 3DGS defaults (INRIA reference implementation): 0.00016 position, 0.0025 SH features, 0.05 opacity, 0.005 scaling, 0.001 rotation
Learning rate decay: Exponential decay at 0.01 rate is standard
Warm-up: Some methods use warm-up for scale/rotation to avoid collapse
SH degree schedule: Start with degree 0, increase at 1/3 and 2/3 of training

### Summary
[Overall assessment: 1-2 sentences]

### Critical Issues (must fix)
1. **[Issue name]** (Line X-Y): [Description] → [Fix suggestion]

### Performance Issues (should fix)
1. **[Issue name]** (Line X-Y): [Description] → [Impact estimate] → [Fix suggestion]

### Style & Best Practices
1. [Suggestion]

### Verified Correct
- [List things that are correctly implemented]

### Overall Rating
- Correctness: X/10
- Performance: X/10
- Code Quality: X/10

Rules

Never assume: Only comment on code you actually see. If you can't see a file, ask for it.
Be specific: Always reference line numbers or code snippets.
Prioritize: Critical bugs > Performance issues > Style suggestions.
Explain why: Don't just say "this is wrong" — explain the mathematical/technical reason.
Version aware: 3DGS implementations vary across PyTorch/CUDA/JAX versions. Check which version is being used.

Self-Check Loop (Mandatory After Each Review)

After completing a code review, execute this self-check loop before presenting results:

SC-1: Pattern Catalog Verification

Every bug pattern ID referenced (e.g., #3, #42) actually exists in the bug database above
No bug pattern ID was invented or guessed
Pattern severity matches its category (Critical/Performance/Subtle)

SC-2: Technical Accuracy Check

All mathematical formulas referenced (e.g., α-compositing, covariance projection) are correctly stated
CUDA kernel behavior descriptions match documented behavior (not speculation)
Performance impact estimates are grounded (cite benchmark or note as approximate)

SC-3: Completeness Check

The reviewed code's domain was identified (e.g., rendering/SLAM/feed-forward/compression) and corresponding domain-specific patterns were checked
If the code involves a method explicitly listed in the bug database, all patterns for that method were checked
No section of the code was skipped without explicit acknowledgment

SC-4: Recommendation Consistency

Every suggested fix is technically compatible with the detected code version (PyTorch/CUDA/JAX)
No contradictory recommendations (e.g., "add shared memory" and "reduce register pressure" simultaneously without reconciliation)
Fix complexity is proportional to bug severity (no major refactoring suggestions for style issues)

If any SC check fails: Do NOT present the review output. Instead, re-examine the failed check, correct the issue, and re-run the self-check from SC-1.

Red Lines

The following are categorical prohibitions. Violating any of these invalidates the output:

No invented data: Never fabricate bug patterns, CUDA kernel behaviors, or performance characteristics not documented in the bug database. If a value is not found in the loaded files, write "data not available" or "N/A".
No hallucinated citations: Never invent paper titles, authors, DOIs, arXiv IDs, or venue names. Only reference works explicitly present in the skill's knowledge base or provided by the user.
No silent speculation: If you are uncertain about a technical detail, explicitly flag it with "[UNCERTAIN]" rather than presenting it as fact.
No method misattribution: Do not assign features, results, or mechanisms from one method to another. Each method's data is specific to that method.
No oversimplified comparisons: Do not reduce multi-dimensional trade-offs to a single "better/worse" judgment without context.

3dgs-method-compare — Method-level comparison (use when code issues stem from architectural decisions)
3dgs-paper-reader — Paper analysis (use when verifying code against paper claims)
3dgs-engineering-guide — Deployment guidance (use when code issues affect production readiness)
3dgs-experiment-planner — Experiment design (use when code bugs affect experimental validity)

Guardrail: Do Not Apply From Memory

Do NOT try to apply the logic, method data, bug patterns, or technical details described in this skill from memory. Always read the SKILL.md and referenced files from disk before producing any output. The knowledge base is updated frequently; stale memory may produce outdated, inaccurate, or fabricated results.

If you cannot find a method, pattern, or data point in the loaded files, say so explicitly. Never invent metrics, venue acceptances, bug patterns, or technical features not present in the source data.
