Modern Csharp Coding Standards

aaronontheweb/dotnet-skills
1.8k installs1.1k stars
Summary

Aaron Namba's skill pushes you toward modern C# idioms that actually matter: records for immutable types, pattern matching over verbose conditionals, and CancellationToken parameters everywhere async happens. The performance guidance is practical, not theoretical. Use Span<T> and ArrayPool<T> where allocations hurt, skip AutoMapper for explicit mapping, and handle business errors with Result types instead of exceptions. It includes four reference files covering value objects, API design, composition patterns, and reflection anti-patterns. If you're still writing C# like it's 2015 or cargo-culting patterns from Stack Overflow, this will modernize your instincts without the usual enterprise architecture bloat.

cupynumeric-migration-readiness

nvidia/skills

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

netlify-config

netlify/context-and-tools

Reference for netlify.toml configuration and site environment variables. Use when configuring build settings, redirects, rewrites, headers, deploy contexts, the `[dev]` block that controls `netlify dev` (command, port, targetPort, framework), or any site-level configuration — and when managing environment variables or secrets with the Netlify CLI, including scoping values to specific deploy contexts. Covers the complete netlify.toml syntax including redirects with splats/conditions, headers, deploy contexts, functions config, edge functions config, and the `[dev]` block (including when `framework` must be `"#custom"` — required when both a custom `command` and `targetPort` are set).

physical-ai-defect-image-generation

nvidia/skills

Use when the user wants to orchestrate defect image generation with NVIDIA Cosmos AnomalyGen (Cosmos-Predict2-derived) on OSMO for PCBA, metal surface, and glass inspection. The Day 0 path handles cold-start with USD-to-ROI, image-edit augmentation, and AnomalyGen to create initial PCBA datasets. The Day 1 path performs inference and labeling on real images. This skill helps with first-time asset setup, creation of finetuning checkpoints, and configuring deployment. Trigger keywords: defect image generation, dig workflow, dig pipeline, defect image detection workflow, aoi pipeline, aoi anomalygen, usd2roi anomalygen, day 0 pcba, day 1 pcba, day 1 real-photo alignment, day 1 manual roi, metal surface anomaly, glass defect, anomalygen finetune, setup_pcb, setup_metal, setup_glass, setup_pretrained, dig setup, dig datasets, dig pretrained checkpoint, dig image-edit endpoint, cosmos defect generation, cosmos-predict2 defect, cosmos-anomalygen, cosmos predict2 finetune.
