Transformers Practitioner Skill

Guides Claude through Hugging Face Transformers work: Hub model loading, pipeline inference, text generation, and Trainer fine-tuning on transformers 5.x.

What it does

  • Gives Claude concrete rules for pipeline, AutoModel, AutoTokenizer, and TrainingArguments under transformers 5.x (PyTorch-only).
  • Supplies pinned install commands plus optional vision (timm, pillow) and audio (librosa, soundfile) extras, and a version check snippet.
  • Covers Hub authentication for gated/private models with token hygiene: no hardcoding, narrowest scope, HF_HUB_DISABLE_IMPLICIT_TOKEN, cache env vars.
  • Provides three canonical patterns (quick pipeline inference, manual model+tokenizer loading, Trainer fine-tuning) and points to detailed reference docs.

Who it's for

  • ML engineers and researchers prototyping NLP, vision, audio, or multimodal models.
  • Teams migrating from transformers v4 to v5 who need API-change awareness.
  • MLOps folks handling HF tokens safely in CI or on servers.

Examples

  1. "Write a text-generation script with Qwen2.5-1.5B" → pipeline code using max_new_tokens correctly.
  2. "Fine-tune a classifier on my CSV dataset" → TrainingArguments + Trainer training script with sensible epochs/batch size.
  3. "I get a 401 loading a gated model" → walks through hf auth login, HF_TOKEN, and license acceptance.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/K-Dense-AI/scientific-agent-skills/HEAD/skills/transformers/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/transformers folder from the GitHub repo K-Dense-AI/scientific-agent-skills into my ~/.claude/skills/transformers/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/K-Dense-AI/scientific-agent-skills.git && mkdir -p ~/.claude/skills && cp -r scientific-agent-skills/skills/transformers ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and clone the repo: git clone https://github.com/K-Dense-AI/scientific-agent-skills.git
  2. Create the skills directory: mkdir -p ~/.claude/skills
  3. Copy just this skill: cp -r scientific-agent-skills/skills/transformers ~/.claude/skills/
  4. Verify ~/.claude/skills/transformers/SKILL.md and its references/ folder exist.
  5. In a Python 3.10+ environment install dependencies: uv pip install "transformers[torch]==5.12.0" huggingface_hub==1.19.0 datasets==5.0.0 accelerate==1.14.0
  6. If you need gated or private models, run hf auth login.
  7. Restart Claude Code and test with a prompt like "use the transformers skill to write pipeline inference code".
