Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Hugging FaceSkillhuggingface/OpenEnv/.claude/skills/alignment-review/SKILL.md
Review code changes for bugs and alignment with OpenEnv principles and RFCs. Use when reviewing PRs, checking code before commit, or when asked to review changes. Implements two-tier review model.

Hugging FaceSkillhuggingface/OpenEnv/.claude/skills/deploy-hf/SKILL.md
Deploy an OpenEnv environment to Hugging Face Spaces. Use when asked to deploy, push to Hugging Face, or update a space.

Hugging FaceSkillhuggingface/OpenEnv/.claude/skills/generate-openenv-env/SKILL.md
Generate OpenEnv environments from a concrete use case (for example, "generate an env for the library textarena"). Use when asked to design or implement a new environment under envs/ by researching a target library/API, selecting matching OpenEnv examples, asking key implementation questions, and building models/client/server/openenv.yaml. Do not use for model training or evaluation tasks.

Hugging FaceSkillhuggingface/OpenEnv/.claude/skills/hf-space-recovery/SKILL.md
Diagnose and recover failing or stuck Hugging Face Space deployments for OpenEnv environments. Use when deploying envs from `envs/` to the Hub (`openenv` namespace with version suffixes), when Spaces are in `BUILDING`/`APP_STARTING`/`RUNTIME_ERROR`, or when release collections need to be reconciled after targeted redeploys.

Hugging FaceSkillhuggingface/OpenEnv/.claude/skills/pre-submit-pr/SKILL.md
Validate changes before submitting a pull request. Run comprehensive checks including lint, tests, alignment review, and RFC analysis. Use before creating a PR, when asked if code is ready for review, or before pushing for PR.

Often used withcreate-agent-adapterdocumentation-consistency
Hugging FaceSkillhuggingface/OpenEnv/.claude/skills/rfc-check/SKILL.md
Determine if proposed changes require an RFC. Use when planning significant changes, before starting major work, or when asked whether an RFC is needed.

Hugging FaceDeletes or force-pushesSkillhuggingface/OpenEnv/.claude/skills/sprint/SKILL.md
Work on a batch of GitHub issues in parallel using Agent Teams. Creates one worktree per issue with TDD enforcement, coordinates via a lead agent, then produces stacked PRs.

Hugging FaceSkillhuggingface/OpenEnv/.claude/skills/update-docs/SKILL.md
Update documentation across the repo after API changes. Finds stale references in docs, examples, docstrings, and fixes them.

Hugging FaceSkillhuggingface/OpenEnv/.claude/skills/watch-pr/SKILL.md
Monitor a PR's CI checks and Greptile code review after submission. Polls CI status, auto-fixes failures via ralph-loop, waits for Greptile review, addresses comments, and iterates until green.

Hugging FaceSkillhuggingface/kernels/kernel-builder/skills/cpu-kernels/SKILL.md
Provides guidance for writing, optimizing, and benchmarking C++ CPU kernels with SIMD intrinsics (AVX2/AVX512) for the Hugging Face kernels ecosystem. Includes a two-phase workflow: Phase 1 correctness (generic → AVX2) and Phase 2 performance exploration (AVX512 with branching trial loop), runtime CPU dispatch, OpenMP threading, and brgemm integration for GEMM-heavy kernels.
Hugging FaceSkillhuggingface/kernels/kernel-builder/skills/cuda-kernels/SKILL.md
Provides guidance for writing and benchmarking optimized CUDA kernels for NVIDIA GPUs (H100, A100, T4) targeting HuggingFace diffusers and transformers libraries. Kernels must be kernel-builder/ABI3-compliant: no pybind11, no setup.py, TORCH_LIBRARY_EXPAND bindings only. Supports models like LTX-Video, Stable Diffusion, LLaMA, Mistral, and Qwen. Includes integration with HuggingFace Kernels Hub (get_kernel) for loading pre-compiled kernels. Includes benchmarking scripts to compare kernel performance against baseline implementations.
Hugging FaceSkillhuggingface/kernels/kernel-builder/skills/rocm-kernels/SKILL.md
Provides guidance for writing and benchmarking optimized Triton kernels for AMD GPUs (MI355X, R9700) on ROCm, targeting HuggingFace diffusers (LTX-Video, SD3, FLUX) and transformers. Core kernels: RMSNorm, RoPE 3D, GEGLU, AdaLN. Includes XCD swizzle, autotune, diffusers integration patterns, and LTX-Video pipeline injection.
Hugging FaceSkillhuggingface/kernels/kernel-builder/skills/triton-kernels/SKILL.md
This skill provides patterns and guidance for developing portable, optimized Triton kernels that run on NVIDIA and AMD GPUs without modification. For backend-specific tuning, see rocm-kernels (AMD) and xpu-kernels (Intel). Use this skill when: 1. **BLOCK_SIZE for reductions must cover the full reduction dimension.** Use triton.next_power_of_2(dim) in the Python wrapper. Never autotune BLOCK_SIZE when it controls the reduction axis — partial rows give wrong results silently. 2. Masked loads need a safe other value. Use other=0.0 for additive contexts (sum,…
Hugging FaceSkillhuggingface/kernels/kernel-builder/skills/xpu-kernels/SKILL.md
Provides guidance for writing, optimizing, and benchmarking Triton kernels for Intel XPU GPUs (Battlemage/Arc Pro B50) using the Xe-Forge optimization framework. Includes an LLM-driven trial-loop workflow (analyze, validate, benchmark, profile, finalize), XPU-specific patterns (tensor descriptors, GRF mode, tile swizzling), KernelBench fused kernels, and Flash Attention.

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
