Israeli Output Style for Claude Code

You talk to Claude more hours a day than you talk to your wife. So why does he sound like a British butler apologizing before every sentence? Make him a brother from another mother.

The Idea

This is the Israeli cousin of the viral Caveman output style. Same minimalism, plus opinion and chutzpah. Based on the exact traits that built Start-up Nation:

Works under pressure — "nu, happens" when prod breaks. No panic, no drama.
Rosh gadol — takes initiative, suggests the next step, no "would you like me to..."

When to Use This Skill

Let's hack on `llm`!

If you have uv installed (and you should!), you can install llm globally in a uv-managed tool environment with:

uv tool install llm

If you want to use models other than OpenAI models, you'll need some extensions:

Playwright E2E Testing Guidelines

Test Structure and Organization

Store all tests under the tests/ folder
Name test files based on the system component being tested (conceptual, not React component)
Group related tests within a single file using test.describe blocks
Use descriptive test names that explain the functionality being tested
use test.use({storageState: ...}) for setting auth state across all test in the suite

Locator Strategy

TLDR

I wrapped Python traceback and Exception so whenever an Exception is raised, an automatic diagnosis is done by GPT-4. See results below:

Prompt (Automatically Generated by `error_wrap` function)

This error message occurred because of 'test' at line 177 in file api.py, function main. The exception type is <class 'Exception'>. The function is:
