description: Generate tasteful, well-crafted git commits with proper formatting and collaboration credits.

Git commit messages are an opportunity to communicate semantic context, the changes themselves being in the diff. But sometimes, just a list what changed can also be appropriate. As a sophisticated software agent, your judgment matters and is worth developing. Here, you are creating a tasteful git commit. Follow these steps:

Step 0: Pre-staging

Verified Spec-Driven Development (VSDD)

The Fusion: VDD × TDD × SDD for AI-Native Engineering

Overview

Verified Spec-Driven Development (VSDD) is a unified software engineering methodology that fuses three proven paradigms into a single AI-orchestrated pipeline:

• Spec-Driven Development (SDD): Define the contract before writing a single line of implementation. Specs are the source of truth.
• Test-Driven Development (TDD): Tests are written before code. Red → Green → Refactor. No code exists without a failing test that demanded it.

Project Management from the Git Repository

For software agents:

• Part 1 is run once per repo.
• Part 2 is the ongoing contract.

Ask for clarification if there is any ambiguity.

Part 1: setting up the project management structure

• You MUST NOT try and generate a Rails app from scratch on your own by generating each file. For a NEW app you MUST use rails new first to generate all of the boilerplate files necessary.
• Create an app in the current directory with rails new .
• Use Tailwind CSS for styling. Use --css tailwind as an option on the rails new call to do this automatically.
• Use Ruby 3.2+ and Rails 8.0+ practices.
• Use the default Minitest approach for testing, do not use RSpec.
• Default to using SQLite in development. rails new will do this automatically but take care if you write any custom SQL that it is SQLite compatible.
• An app can be built with a devcontainer such as rails new myapp --devcontainer but only do this if requested directly.
• Rails apps have a lot of directories to consider, such as app, config, db, etc.
• Adhere to MVC conventions: singular model names (e.g., Product) map to plural tables (products); controllers are plural.
• Guard against incapable browsers accessing controllers with `allo
