Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned qodex-ai/ai-agent-skills at 6ea9f00885.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill provides a comprehensive guide for fine-tuning Large Language Models (LLMs) to adapt them for specific tasks or domains. It covers the entire workflow from data preparation and model selection to training execution and evaluation, ensuring models align with unique organizational needs.

When to use it

  • You need to customize a pre-trained LLM to understand industry-specific jargon or proprietary workflows.
  • You want to reduce hallucinations by training the model on verified, high-quality datasets relevant to your use case.
  • You are building an AI agent that requires distinct behavioral patterns or output formats not covered by base models.
  • You need a structured approach to iterate through hyperparameter tuning and loss function optimization for better convergence.

Key capabilities

  • Data Preparation: Guidance on cleaning, formatting, and splitting datasets for effective training.
  • Model Selection: Advice on choosing the right base architecture (e.g., Llama, Mistral) for your specific resource constraints.
  • Training Configuration: Instructions on setting up learning rates, batch sizes, and epochs for optimal performance.
  • Evaluation Metrics: Methods to assess model accuracy, perplexity, and task-specific success rates post-training.

Example prompts

  • "Generate a step-by-step plan to fine-tune an LLM using a custom dataset of medical case studies."
  • "What are the best practices for preparing JSON-formatted data before starting the fine-tuning process?"
  • "Explain how to evaluate the performance of a fine-tuned model against its base version using specific metrics."

Tips & gotchas

Ensure your training dataset is high-quality and representative; poor data leads directly to degraded model performance regardless of configuration. Start with smaller batch sizes if you have limited GPU memory, as this prevents out-of-memory errors during the initial training phase.
