io.github.NVIDIA/Model-Optimizer/deployment

Serve a quantized or unquantized LLM checkpoint as an OpenAI-compatible API endpoint using vLLM, SGLang, or TRT-LLM. Use when user says "deploy model", "serve model", "start vLLM server", "launch SGLang", "TRT-LLM deploy", "AutoDeploy", "benchmark throughput", "serve checkpoint", or needs an inference endpoint from a HuggingFace or ModelOpt-quantized checkpoint. Do NOT use for quantizing models (use ptq) or evaluating accuracy (use evaluation).

io.github.onyx-dot-app/onyx/browser

Core browser usage guide. Read this before running any browser commands. Covers the snapshot-and-ref workflow, navigating pages, interacting with elements (click, fill, type, select), extracting text and data, taking screenshots, managing tabs, handling forms and auth, waiting for content, running multiple browser sessions in parallel, and troubleshooting common failures. Use when the user asks to interact with a website, fill a form, click something, extract data, take a screenshot, log into a site, test a web app, or automate any browser task.

io.github.nukeop/nuclear/writing-plugins

Use when writing, scaffolding, or modifying Nuclear plugins. Covers plugin structure, manifest, entry point, provider types, available APIs, and publishing. Trigger phrases include "create a plugin", "write a plugin", "plugin scaffold", "streaming provider", "metadata provider".

io.github.redis/node-redis/maintainer-review

Review a GitHub issue or pull request URL as a node-redis maintainer, with a staged assessment of whether the claim is real, practically important, already solvable with supported functionality, correctly scoped, better served by another design, and worth maintainer and contributor effort. Use when assessing issue validity or severity, deciding whether an issue should be prioritized or closed, determining whether a requested feature represents an unmet need rather than a discoverability or usage gap, judging whether a PR is worth bringing to mergeable quality, comparing open PRs or alternative designs, separating code quality from repository readiness, or drafting a concise maintainer assessment. When closure, additional evidence, or code changes should be requested, also produce a polite, concise, complete, copy-paste-ready maintainer comment.

io.github.redis/ioredis/code-change-verification

Verify ioredis code changes before handoff. Use when an agent changes or reviews runtime TypeScript, Redis command support, generated typings, tests, docs tied to behavior, build tooling, release-sensitive files, or any task that needs choosing and running the right local validation commands.

io.github.sickn33/antigravity-awesome-skills/hugging-face-model-trainer

Train or fine-tune language and vision models using TRL (Transformer Reinforcement Learning) or Unsloth with Hugging Face Jobs infrastructure. Covers SFT, DPO, GRPO and reward modeling training methods, plus GGUF conversion for local deployment.

io.github.sickn33/antigravity-awesome-skills/code-simplification

Simplifies code for clarity. Use when refactoring code for clarity without changing behavior. Use when code works but is harder to read, maintain, or extend than it should be. Use when reviewing code that has accumulated unnecessary complexity.

io.github.sickn33/antigravity-awesome-skills/code-showcase-testing-patterns

Jest testing patterns, factory functions, mocking strategies, and TDD workflow. Use when writing unit tests, creating test factories, or following TDD red-green-refactor cycle.

io.github.sickn33/antigravity-awesome-skills/code-review-and-quality

Conducts multi-axis code review. Use before merging any change. Use when reviewing code written by yourself, another agent, or a human. Use when you need to assess code quality across multiple dimensions before it enters the main branch.

io.github.sickn33/antigravity-awesome-skills/styleseed-design-review

Reviews UI/frontend code and tells you exactly why it "looks AI-generated" — then how to fix it.

io.github.sickn33/antigravity-awesome-skills/review-swarm

Parallel read-only multi-agent review of a current git diff or explicit file scope to find behavioral regressions, security or privacy risks, performance or reliability issues, and contract or test coverage gaps.

io.github.sickn33/antigravity-awesome-skills/review-and-simplify-changes
