Install

Skills CLI

npx skills add itsmostafa/llm-engineering-skills

Asks which skills and agents to install. Just one: npx skills add itsmostafa/llm-engineering-skills --skill agents — add -g for every project.

Claude Code

git clone https://github.com/itsmostafa/llm-engineering-skillscp -r "llm-engineering-skills/skills/agents" ~/.claude/skills/

Copies the agents skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add itsmostafa/llm-engineering-skills

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • agents

    Patterns and architectures for building AI agents and workflows with LLMs. Use when designing systems that involve tool use, multi-step reasoning, autonomous decision-making, or orchestration of LLM-driven tasks.

    skills/agents/SKILL.md on GitHub (opens in a new tab)
  • context-engineering

    Strategies for managing LLM context windows effectively in AI agents. Use when building agents that handle long conversations, multi-step tasks, tool orchestration, or need to maintain coherence across extended interactions.

    skills/context-engineering/SKILL.md on GitHub (opens in a new tab)
  • lora

    Parameter-efficient fine-tuning with Low-Rank Adaptation (LoRA). Use when fine-tuning large language models with limited GPU memory, creating task-specific adapters, or when you need to train multiple specialized models from a single base.

    skills/lora/SKILL.md on GitHub (opens in a new tab)
  • mlx

    Running and fine-tuning LLMs on Apple Silicon with MLX. Use when working with models locally on Mac, converting Hugging Face models to MLX format, fine-tuning with LoRA/QLoRA on Apple Silicon, or serving models via HTTP API.

    skills/mlx/SKILL.md on GitHub (opens in a new tab)
  • prompt-engineering

    Crafting effective prompts for LLMs. Use when designing prompts, improving output quality, structuring complex instructions, or debugging poor model responses.

    skills/prompt-engineering/SKILL.md on GitHub (opens in a new tab)
  • pytorch

    Building and training neural networks with PyTorch. Use when implementing deep learning models, training loops, data pipelines, model optimization with torch.compile, distributed training, or deploying PyTorch models.

    skills/pytorch/SKILL.md on GitHub (opens in a new tab)
  • qlora

    Memory-efficient fine-tuning with 4-bit quantization and LoRA adapters. Use when fine-tuning large models (7B+) on consumer GPUs, when VRAM is limited, or when standard LoRA still exceeds memory. Builds on the lora skill.

    skills/qlora/SKILL.md on GitHub (opens in a new tab)
  • rlhf

    Understanding Reinforcement Learning from Human Feedback (RLHF) for aligning language models. Use when learning about preference data, reward modeling, policy optimization, or direct alignment algorithms like DPO.

    skills/rlhf/SKILL.md on GitHub (opens in a new tab)
  • transformers

    Loading and using pretrained models with Hugging Face Transformers. Use when working with pretrained models from the Hub, running inference with Pipeline API, fine-tuning models with Trainer, or handling text, vision, audio, and multimodal tasks.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
