Spec mode guidelines

You are a senior software engineer assisting a user in defining and planning a new feature. Your goal is to guide the user through a structured process, resulting in a clear set of documents that can be handed off for implementation.

Guiding principles

Planner, not doer:
- Your primary role is to create planning artifacts (requirements.md, design.md, tasks.md).
- You MUST NOT write the implementation code yourself.
Phased approach:

Stop letting Aider code blindly - try this first

Using Aider's /ask and /architect commands to approach larger tasks.

Aider is one of the best AI coding tools available today (in my opinion!). It's a brilliant AI coding assistant that integrates with any LLM, in any code editor.

However, Aider can often feel very eager to make changes. It jumps right into coding after I type anything. I noticed a pattern:

I would describe what I wanted
Aider would start coding right away

Test storybook stories in Vitest + React testing library

Let's say you have these files:

Chat.tsx
Chat.stories.tsx
Chat.test.tsx

The test file can be written to use Storybook stories:

JavaScript without npm?
A dive into Rails 7's importmap approach

Using JavaScript in Rails has a very long history. With Rails 7, the latest approach has been to move away from the tools from the JavaScript community like npm, yarn, and Webpack. Instead, Rails 7 introduces importmap-rails as a solution that “embraces the platform” and uses native JavaScript modules (also known as “ES Modules” or “ESM”).

What’s Importmap-rails?

Importmap-rails is touted as a gem that “let you import JavaScript modules directly from the browser” ¹. The documentation claims that “this frees you from needing Webpack, Yarn, npm, or any other part of the JavaScript toolchain.”

At first, I felt like those claims are a bit ambiguous and a bit of marketing hype. After exploring importmap-rails a bit more, I think I have another way of looking at it. importmap-rails is a replacement for npm for app builders. That is: take away npm’s authoring tools (like `

	#!/usr/bin/env bash
	# Generates a prompt for a PR summary and copies it to clipboard.
	#
	# Usage: prompt-pr.sh 1234
	#
	# Paste into Claude and watch it generate a PR summary.
	#
	# Try following up with these questions:
	#
	# - given the PR description and this plan, is there anything in this PR that may need changing?
