Hugging Face Skills

This repository contains skills for your coding agent to use when working with Hugging Face. It's compatible Claude Code, Google Gemini, and OpenAI Codex.

Skills are self-contained folders that package instructions, scripts, and resources. Each folder includes a SKILL.md file with YAML frontmatter (name and description) followed by the guidance your coding agent follows while the skill is active.

Note

'Skills' is actually an Anthropic term used within Claude Code and not adopted by other agent tools, but we love it! OpenAI Codex uses an AGENTS.md file to define the instructions for your coding agent. Google Gemini uses 'extensions' to define the instructions for your coding agent in a gemini-extension.json file.

Humanity's Last Hackathon (of 2025)

December 2025 — We're kicking off this skills library with a community hackathon. Use coding agents to ship real contributions: evaluate models, build datasets, fine-tune LLMs, and earn XP on a community leaderboard.

Week	Quest	Skill
1	Evaluate a Hub Model	hf_model_evaluation/
2	Publish a Hub Dataset	hf_dataset_creator/
3	Supervised Fine-Tuning	hf-llm-trainer/

Get started: Join the hackathon org → Read apps/quests/01_start.md → Pick a quest

Installation

Hugging Face skills are compatible with Claude Code, Codex, and Gemini CLI. With integrations Cursor, Windsurf, and Continue, on the way.

Claude Code

1. Register the repository as a plugin marketplace:

/plugin marketplace add huggingface/skills

2. To install a skill, run:

/plugin install <skill-folder>@huggingface-skills

For example:

/plugin install hf-llm-trainer@huggingface-skills

Codex

1. Codex will identify the skills via the AGENTS.md file. You can verify the instructions are loaded with:

codex --ask-for-approval never "Summarize the current instructions."

2. For more details, see the Codex AGENTS guide.

Gemini CLI

1. This repo includes gemini-extension.json to integrate with the Gemini CLI.

2. Install locally:

gemini extensions install . --consent

or use the GitHub URL:

gemini extensions install https://github.com/huggingface/skills.git --consent

4. See Gemini CLI extensions docs for more help.

Skills

This repository contains a few skills to get you started. You can also contribute your own skills to the repository.

Available skills

Skill Folder	Description	Documentation
hf_dataset_creator/	Prompts, templates, and scripts for creating structured training datasets.	SKILL.md
hf_model_evaluation/	Instructions plus utilities for orchestrating evaluation jobs, generating reports, and mapping metrics.	SKILL.md
hf-llm-trainer/	Comprehensive training skill with SKILL.md guidance, helper scripts (e.g., train_sft_example.py, convert_to_gguf.py, cost estimators).	SKILL.md
hf-paper-publisher/	Tools for publishing and managing research papers on Hugging Face Hub. Index papers from arXiv, link papers to models/datasets, generate professional research articles from templates, and manage paper authorship.	SKILL.md

Using skills in your coding agent

Once a skill is installed, mention it directly while giving your coding agent instructions:

• "Use the HF LLM trainer skill to estimate the GPU memory needed for a 70B model run."
• "Use the HF model evaluation skill to launch run_eval_job.py on the latest checkpoint."
• "Use the HF dataset creator skill to draft new few-shot classification templates."
• "Use the HF paper publisher skill to index my arXiv paper and link it to my model."

Your coding agent automatically loads the corresponding SKILL.md instructions and helper scripts while it completes the task.

Contribute or customize a skill

1. Copy one of the existing skill folders (for example, hf_dataset_creator/) and rename it.
2. Update the new folder’s SKILL.md frontmatter:

   ---
   name: my-skill-name
   description: Describe what the skill does and when to use it
   ---
   
   # Skill Title
   Guidance + examples + guardrails

3. Add or edit supporting scripts, templates, and documents referenced by your instructions.
4. Reinstall or reload the skill bundle in your coding agent so the updated folder is available.
