"implement core feature <name>", "build the <component> core feature", "next core feature", "next core", "continue building core", "core-builder" — this skill implements a specific feature from a core-blueprint outline (requires core-outline.md in the project). Generates working simplified Java source code, unit/integration tests, and a 10-section tutorial chapter with Mermaid diagrams and ★ Insight blocks, all verified to compile and pass. The source project may be in any language — the output is always simplified Java. Uses the inside-out approach starting from the integration point.
