Setup Instructions

1. Add the function to ~/.zshrc

Copy the function from the file above and paste it into your ~/.zshrc, then run:

source ~/.zshrc

2. Create a Claude Code skill

Tell your Claude Code agent:

Create a custom skill called my-custom-guidelines at ~/.claude/skills/my-custom-guidelines/SKILL.md with the following content:

---
name: my-custom-guidelines
description: Fetch and apply custom AI guidelines from the TurkHosting repo to the current project
disable-model-invocation: true
allowed-tools: Bash(mkdir *), Bash(gh *)
---

Fetch the custom guidelines file from the TurkHosting/my-custom-guidelines-for-ai-agents repo and save it to the current project directory.

Run the following steps:
1. Create the `.ai/guidelines/` directory if it does not exist: `mkdir -p .ai/guidelines`
2. Download the guidelines: `gh api repos/TurkHosting/my-custom-guidelines-for-ai-agents/contents/.ai/guidelines/my-custom-guidelines.md --jq '.content' | base64 -d > .ai/guidelines/my-custom-guidelines.md`
3. Confirm to the user that the file was saved to `.ai/guidelines/my-custom-guidelines.md`

If `gh` is not installed or not authenticated, inform the user to run `brew install gh` and `gh auth login`.

After that, you can use /my-custom-guidelines inside Claude Code to fetch the latest guidelines into any project.
