Spec Kit

What it does

Spec Kit turns loose prompting into a repeatable process. You describe what you want in a specification, and the agent follows a fixed flow: spec, technical plan, task list, then implementation. Each step writes a file you can review.

Why it is useful

• The agent builds from an agreed spec instead of guessing, so large features drift less.
• The spec and the plan stay in the repo as living documentation.
• It works with many coding agents, not only one vendor.

How to use it

Install the specify CLI as shown in the README, then run specify init in your project. Use the slash commands it adds to move from spec to plan to tasks.

Watch out for

• The process adds overhead. It pays off on multi-day features, less on small fixes.
• Version 1.0.0 shipped in August 2026. Older blog posts may show outdated commands.
