Hugging Face Skills: The Revolutionary AI Agent Framework That's Standardizing ML Workflows Across All Major Coding Platforms with 4.5k+ Stars

In the rapidly evolving landscape of AI development, one of the biggest challenges developers face is the fragmentation of tools and workflows across different coding agents. Enter Hugging Face Skills – a groundbreaking repository that's revolutionizing how we approach AI/ML task definitions by creating a standardized format that works seamlessly across all major coding agent platforms.

With over 4,500 GitHub stars and growing rapidly since its launch in November 2025, this Apache 2.0 licensed project is solving a critical problem: making AI agent skills truly interoperable across OpenAI Codex, Anthropic's Claude Code, Google DeepMind's Gemini CLI, and Cursor.

What Are Hugging Face Skills?

Hugging Face Skills are standardized definitions for AI/ML tasks like dataset creation, model training, and evaluation. Think of them as reusable, self-contained packages that combine instructions, scripts, and resources for AI agents to execute specific use cases.

Each skill is structured as a folder containing:

• SKILL.md file with YAML frontmatter (name and description)
• Detailed guidance that your coding agent follows
• Supporting scripts and templates
• Resource files needed for execution

The genius of this approach lies in its universal compatibility. While different platforms use different terminology – Anthropic calls them "Skills," OpenAI uses "AGENTS.md" files, and Google Gemini uses "extensions" – Hugging Face Skills supports them all through a single, standardized format.

Cross-Platform Installation Guide

One of the most impressive aspects of Hugging Face Skills is how seamlessly it integrates across different coding agent platforms:

Claude Code Integration

# Register the repository as a plugin marketplace
/plugin marketplace add huggingface/skills

# Install a specific skill
/plugin install hugging-face-cli@huggingface/skills

OpenAI Codex Integration

# Codex automatically identifies skills via AGENTS.md
codex --ask-for-approval never "Summarize the current instructions."

Google Gemini CLI Integration

# Install locally
gemini extensions install . --consent

# Or install from GitHub URL
gemini extensions install https://github.com/huggingface/skills.git --consent

Cursor Integration

The repository includes Cursor plugin manifests with .cursor-plugin/plugin.json and .mcp.json configured with the Hugging Face MCP server URL. Simply install from the repository URL via Cursor's plugin flow.

Comprehensive Skill Library

The repository currently offers eight powerful skills that cover the entire ML workflow:

1. Hugging Face CLI Skill

Execute Hugging Face Hub operations including downloading models/datasets, uploading files, managing repositories, and running cloud compute jobs.

2. Hugging Face Datasets Skill

Create and manage datasets on Hugging Face Hub with support for initializing repos, defining configs, streaming row updates, and SQL-based dataset querying.

3. Hugging Face Evaluation Skill

Add and manage evaluation results in model cards, extract evaluation tables from README content, and run custom evaluations with vLLM/lighteval.

4. Hugging Face Jobs Skill

Run compute jobs on Hugging Face infrastructure, execute Python scripts, manage scheduled jobs, and monitor job status.

5. Hugging Face Model Trainer Skill

Train or fine-tune language models using TRL on Hugging Face Jobs infrastructure. Covers SFT, DPO, GRPO, and reward modeling training methods, plus GGUF conversion for local deployment.

6. Hugging Face Paper Publisher Skill

Publish and manage research papers on Hugging Face Hub, create paper pages, link papers to models/datasets, and generate professional markdown-based research articles.

7. Hugging Face Tool Builder Skill

Build reusable scripts for Hugging Face API operations, perfect for chaining API calls or automating repeated tasks.

8. Hugging Face Trackio Skill

Track and visualize ML training experiments with Trackio, log metrics via Python API, and create real-time dashboards synced to HF Spaces.

Using Skills in Practice

Once installed, using skills is incredibly intuitive. Simply mention the skill directly in your instructions to your coding agent:

• "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 to complete the task.

Contributing and Customizing Skills

The project encourages community contributions with a straightforward process:

1. Copy an existing skill folder and rename it
2. Add supporting scripts and templates
3. Update marketplace.json with a human-readable description
4. Run the publish script: ./scripts/publish.sh
5. Reinstall the skill bundle in your coding agent

Update the SKILL.md frontmatter:

---
name: my-skill-name
description: Describe what the skill does and when to use it
---

# Skill Title
Guidance + examples + guardrails

The Marketplace Ecosystem

The .claude-plugin/marketplace.json file creates a browsable marketplace of skills with human-readable descriptions. This dual-description system is clever: SKILL.md descriptions guide when Claude activates the skill, while marketplace descriptions help humans discover and understand available skills.

Technical Architecture and Innovation

What makes Hugging Face Skills truly revolutionary is its approach to standardization without sacrificing platform-specific optimizations. The repository includes:

• Universal compatibility files: AGENTS.md for Codex, gemini-extension.json for Gemini CLI
• Platform-specific manifests: .cursor-plugin/plugin.json and .mcp.json for Cursor
• Automated validation: CI that ensures skill names and paths match across all formats
• Regeneration scripts: Automated tools to keep all manifests in sync

Real-World Impact and Use Cases

The project is already showing significant impact in the AI development community:

• Standardization: Eliminating the need to rewrite skills for different platforms
• Productivity: Reducing setup time from hours to minutes
• Collaboration: Enabling teams to share skills across different tool preferences
• Innovation: Accelerating AI development by providing battle-tested workflows

Future Roadmap and Community Growth

With 13 active contributors and rapid growth since launch, the project shows strong momentum. The recent addition of Cursor plugin support (February 2026) demonstrates the team's commitment to staying current with emerging platforms.

The standardized Agent Skill format that Hugging Face Skills follows suggests this could become the de facto standard for AI agent task definitions across the industry.
