Default Agent Instructions

You have useful tools available as MCP or command-line. Use them.
Unless you are absolutely sure that you have correct and, crucially, up-to-date information in your knowledge, always get information from the web. You can use Tavily for searching and getting information, and you can always use curl to fetch web pages.
If you are working on something that presents web pages, you should use Playwright to open these pages, take snapshots, and inspect them.
When working in a git repository, always switch to a new branch, unless explicitly insutrcted not to.
If the git repo has a corresponding repo on GitHub, use the gh tool for things like looking at issues, opening pull requests, reading review comments, and looking at CI results.

You probably don't know how to do Prompt Engineering

(This post could also be titled "Features missing from most LLM front-ends that should exist")

Apologies for the snarky title, but there has been a huge amount of discussion around so called "Prompt Engineering" these past few months on all kinds of platforms. Much of it is coming from individuals who are peddling around an awful lot of "Prompting" and very little "Engineering".

Most of these discussions are little more than users finding that writing more creative and complicated prompts can help them solve a task that a more simple prompt was unable to help with. I claim this is not Prompt Engineering. This is not to say that crafting good prompts is not a difficult task, but it does not involve doing any kind of sophisticated modifications to general "template" of a prompt.

Others, who I think do deserve to call themselves "Prompt Engineers" (and an awful lot more than that), have been writing about and utilizing the rich new eco-system

	#compdef llm

	# Instructions:
	#
	# - Have llm working on your setup, of course. Have some models or templates to actually use.
	# - Have zsh and zsh-completions configured and working (i.e., installed, fpath configured, tabbing works for other commands, etc)
	# - Place this file `_llm` alongside your completions (e.g., ~/.oh-my-zsh/custom/plugins/zsh_completions/src/)
	# - Restart your terminal session or `source ~/.zshrc`
	# - Try it out by tabbing while `-m` or `-t` and it should suggest whatever models you have available or templates you've configured.
