Spec Coding

Spec Coding is a method for building software that focuses on defining exactly what the software should do and what it shouldn't do before any code is written. It helps make sure that everyone involved understands the requirements clearly. This approach uses clear criteria to guide AI tools, making sure the code they create works correctly and as intended.

Benefits

Writing down the specifications first helps prevent mistakes and saves time later. It ensures that everyone agrees on what needs to be built, and these agreements can easily be turned into tests. This means the code produced, especially with AI help, is more likely to be right the first time.

Use Cases

Spec Coding involves three main steps. First, you clearly define the main goal, what's not included, and the specific conditions the software must meet. This includes thinking about tricky situations like missing information or when many things happen at once. Second, you break down the plan into smaller parts and write tests for them. Third, you use the defined specifications as the main guide for AI coding tools. This keeps the AI focused on the task and prevents it from adding extra features or making changes that weren't planned. Spec Coding also provides templates for different types of specifications, like for features, APIs, or databases, to help standardize the process.

Spec Coding is especially helpful for solo developers or small teams because it keeps everyone on the same page, even when work is interrupted. It helps save time by focusing on the most important details that prevent the most problems. When using AI for coding, these specifications act as important guidelines to ensure the AI stays on track.
