GOAL
Set up an empty Node.js project to build a library that detects and monitors light/dark system theme across macOS, Windows and Linux (GNOME/KDE/Wayland/X11), starting with an AGENTS.md brief and a detailed MVP plan.
- +0Prompt · +0Create a Node.js library to read/detect system theme (light/dark) on macOS, Windows, Linux (GNOME/KDE/Wayland/X11). Support poll mode (getSystemTheme()) and monitor mode with fallback. Research each OS first, then write AGENTS.md and a detailed 0-to-1 plan in .agents/plans/00-initial-setup.md.
- +0mAgent did · +0mRan a long series of web/perplexity searches and page fetches to research how each OS exposes and notifies theme changes: macOS AppleInterfaceStyle/AppleInterfaceThemeChangedNotification, Windows AppsUseLightTheme registry key + RegNotifyChangeKeyValue/WM_SETTINGCHANGE, GNOME gsettings color-scheme, KDE kdeglobals/kreadconfig5, XDG desktop portal Settings interface, and X11 XSETTINGS.
- +2mAgent did · +2mChecked existing package.json and folder structure, then wrote AGENTS.md with the project brief (scope, API requirements, platform targets, MVP principles) and .agents/plans/00-initial-setup.md with a detailed phased plan (foundation, per-OS providers, monitoring, tests, docs, support matrix, risks).
- +4mAgent did · +4mRe-read both created files to verify content, then checked git status and found the folder isn't yet a git repository.
- +4mOutcome · +4mSession ended with AGENTS.md and .agents/plans/00-initial-setup.md created, laying out the API, platform detection/monitoring strategy, and phased MVP implementation plan; no code written yet, no git repo initialized.
VERDICT
I'd start the next prompt by also asking it to init git and scaffold the package structure (src/, providers/) alongside the docs, since it noticed there was no git repo at the end but didn't act on it. The research-first approach worked well and gave the plan solid grounding in real OS APIs (registry keys, dbus portal, gsettings) rather than guesses, so I'd keep that step.
