  "description": "Coder writes, fixes and reviews code. It builds websites, web apps, mobile apps and AI agents after up to three quick questions, with complete files and steps to run them. It finds and fixes bugs from error messages or broken code, and reviews, explains and converts code. Its tools supply the exact values that code needs: a color theme from your brand color with readable text in light and dark mode, color contrast checks, timestamp, date and time zone conversion, and cron schedules explained with their next run times.",

        "longDescription": "Coder writes, fixes and reviews code, from a first website to a working app.\n\nWhat you can do:\n- Build a website, landing page or portfolio: answer up to three quick questions and get a complete one-file website you can open in any browser.\n- Build a web app, a mobile app (React Native with Expo) or an AI agent, with every file written in full and the steps to run it.\n- Get a matching look from one color: Coder turns your brand color into a full theme for light and dark mode, with text sizes and spacing, in which every text and background pair is measured for readability.\n- Fix bugs: paste an error message or broken code and get the cause, the line it is on and the corrected code.\n- Review, explain, refactor or convert code to another language.\n- Check color contrast against the WCAG AA and AAA levels, and get the closest color that passes.\n- Convert Unix timestamps, dates and time zones, add or subtract time, and count the days and weekdays between two dates.\n- Understand a cron schedule: what it means in plain words, common mistakes in it, and when it runs next in your time zone.\n\nWho it is for: beginners who want something that works, makers and small business owners building a site or an app, students, and developers who want exact answers for colors, dates and schedules.\n\nHow it works: Coder writes, fixes and reviews the code in the chat. For exact values it uses four small tools on the AI Sciences Lab server: a theme builder, a contrast checker, a date and time converter and a cron reader. They receive only short values such as colors, dates and cron expressions, never your code, and they store nothing.\n\nLimitations: Coder does not run your code, so test what you build. It does not host or publish websites or apps; it gives you the files and the steps. Time zone results follow the standard time zone database and can lag behind very recent rule changes. Coder is an independent plugin by AI Sciences Lab.",
