OpenAI Codex Skills

Autonomously simplifies code in your working changes or targeted files. Detects staged or unstaged git changes, analyzes for simplification opportunities following clean code and clean architecture principles, applies improvements directly, runs tests to verify nothing broke, and shows a structured summary with reasoning. Triggers on "simplify this", "refactor this", "clean up my changes", "absolute-simplify", "simplify my code", "make this cleaner", "tidy this up", "reduce complexity", "flatten this", "remove dead code", or when code needs clarity improvements, nesting reduction, or redundancy removal. Language-agnostic at base with deep opinions for JS/TS/React, Python, and Go.

End-to-end, phase-gated software development lifecycle for AI agents. Turns a ticket, task, plan, or migration into a validated design, a dependency-graphed task board, and verified code. Triggers on "build this end-to-end", "plan and build", "break this into tasks", "pick up this ticket", "grill me on this", "run this migration", "absolute-work this", or any multi-step development task. Relentlessly interviews to a shared design, writes a reviewed spec, decomposes into atomic tasks on a persistent markdown board, then peels tasks one safe wave at a time with test-first verification. Handles features, bugs, refactors, greenfield projects, planning breakdowns, and migrations.

Use this skill when building user interfaces that need to look polished, modern, and intentional - not like AI-generated slop. Triggers on UI design tasks including component styling, layout decisions, color choices, typography, spacing, responsive design, dark mode, accessibility, animations, landing pages, onboarding flows, data tables, navigation patterns, and any question about making a UI look professional. Covers CSS, Tailwind, and framework-agnostic design principles.
