Maintainer review activity heatmap
Maintainer Strategy: Maintainer Sweet Spot: PRs under 150 lines merge in ~26 hours (96% approval). Large PRs (>500 lines) take ~195 hours (45% approval). Keep your diff compact for rapid review.
Description As the project grows with community contributions, we need automated linting and formatting to keep the "Zero Bloat" code clean and readable. Tasks Add a basic .eslintrc and .prettierrc. Add a lint script to package.json (or instructions in README for those not using npm).
Description Currently, users have to click a small avatar icon in the top right to enter their API key. This is counter-intuitive for new users. Tasks Create a dedicated, prominent "Settings" view, and simplify the clutter of icons around there. Add a first-time setup wizard for users who haven't entered an API key yet. Improve the layout and styling of the renderSettingsModal function in script.js.
Description The Git icon is present in the activity bar, but clicking it does nothing. We need a way to view diffs and perform basic Git operations within the WebContainer. Tasks Create a "Source Control" view tab in the sidebar. (will need logic for tab switching from the file exporer and vice versa). Implement git status and git diff visualization. (not desperately needed, but would make a big "diff" ;) ) Able to commit changes and push to remotes.
Description The top menubar items (File, Edit, etc.) are currently static placeholders. Basic IDE functionality like "Save," "Search," and "New File" should be accessible from these menus. Tasks All options, etc.: wire "File > Save" to the saveActiveFile() function in script.js. Or implement a global "Search" modal (Edit > Find). Or add "New File" and "New Folder" functionality to the File menu. etc... there are a LOT of options in antigravity, but I guess they don't ALL need adding.
Description The model is currently hardcoded as gemini-3.1-pro-preview in agent.js. The dropdown in the UI toolbar is a visual placeholder and does not actually switch models. Tasks Link the toolbar model dropdown to AgentManager.model. Ensure the selected model persists in localStorage. Dynamically fetch/list available models based on the selected API provider.
