Steers coding agents toward call-site-first design, plain-data domain models, and tests that pin behavior.
Skill Codex
Use before building a feature, refactoring, designing APIs or module boundaries, doing performance work, or reviewing a pull request or diff, in any repo. Covers plain data, call-site-first API design, simple control flow, boundary parsing, behavior-first tests, and lens-based code review. Skip it only for small bug…

Write code that favors plain data, pure logic, clear call sites, and early architectural thinking. These are strong defaults, not rigid laws: follow the surrounding codebase, framework constraints, and language norms when they clearly matter more.

Use when an LLM is doing non-trivial coding work, including implementing features, fixing bugs, refactoring, designing APIs or module boundaries, writing tests, reviewing code, or preparing to commit. Guides the model toward plain data, top-down API design, simple control flow, SOLID without ceremony, boundary…
