Some basic rules

Fork develop and branch off it. Pull requests MUST be directed to the develop branch.
For customisation and extensions, see the documentation. For adding built-in engines or bang commands, follow the patterns in src/server/extensions/engines and src/server/extensions/commands/builtins.
If you use AI, ensure your code is reviewed, meets the coding standards below, and is not overly engineered.

Coding standards

Functions that return a value - use arrow functions (e.g. const getX = () => value).
Functions that do not return (side-effect only) - use regular function declarations.
Internal / private helpers - prepend with _ (e.g. _parseQuery, _formatDate).
CSS - Reuse existing app classes where possible (see Styling for a list). Must use SCSS/CSS variables (e.g. $primary or var(--text-primary)) so themes and light/dark mode keep working wel.
Structure - Keep things modular; follow the existing folder structure (e.g. one folder per plugin, one file or folder per engine).
