Spec Kit becomes the senior engineer you can't afford to hire.
Carry conventions
One constitution, every repo.
Your stack, your style, your naming — encoded once. Switch projects without reteaching the AI who you are.
Ship with discipline
Specify before you build.
A 10-minute spec saves a Saturday of rework. The agent stops guessing what "done" means.
Leverage
You review. Claude writes.
Rebuild a landing page or a CLI in a weekend. The spec is your project plan and your acceptance test.
