Developer Foundations
Created by CodeCraft LLCv1.0.0 · updated 2026-10-16Free, complete starting points - SQL, CSS layout, unit testing, READMEs and writing your own skills.
Anyone learning a new area or wanting their agent to cover the basics properly: first SQL queries, first layouts with Flexbox and Grid, first unit tests, a project's first README, or a first skill for the marketplace.
Each skill is complete on its own, not a teaser: the core rules with their reasons, the common bugs mapped from symptom to cause, and worked examples in deep-dive references. They are free so every account gets a solid baseline.
