+            - If it's a feature request, check for: clear description of desired behavior, use case. Only ask for what's actually missing.
+            - If the issue already has everything needed, just acknowledge it and label it.
+            - Never exceed 6 items total.

+
+            1. One sentence summarizing what this PR does.
+            2. **Action items** — only list things that actually need to be fixed or addressed. If the PR looks good, say so and skip this section.
+
+            Rules:
+            - Be brief. No filler, no praise padding.
+            - Focus on: bugs, security issues, missing edge cases, breaking changes.
+            - If the PR touches UI text or adds new strings, remind to update translation files in src/i18n/locales/.
+            - If the PR modifies Tauri commands, remind to check the unused-commands test.
+            - Do not nitpick style or formatting — the project has automated linting.
+            - Never exceed 8 lines total.

-- After your changes, instead of running specific tests or linting specific files, run "pnpm format && pnpm lint && pnpm test". It means that you first format the code, then lint it, then test it, so that no part is broken after your changes.
-- Don't leave comments that don't add value.
-- Do not duplicate code unless you have a very good reason to do so. It is important that the same logic is not duplicated multiple times.
-- Before finishing the task and showing summary, always run "pnpm format && pnpm lint && pnpm test" at the root of the project to ensure that you don't finish with broken application.
-- If there is a global singleton of a struct, only use it inside a method while properly initializing it, unless I have explicitly specified in the request otherwise.
-- If you are modifying the UI, do not add random colors that are not controlled by src/lib/themes.ts file.
+## Testing and Quality
+
+- After making changes, run `pnpm format && pnpm lint && pnpm test` at the root of the project
+- Always run this command before finishing a task to ensure the application isn't broken
+- `pnpm lint` includes spellcheck via [typos](https://github.com/crate-ci/typos). False positives can be allowlisted in `_typos.toml`
+
+## Code Quality
+
+- Don't leave comments that don't add value
+- Don't duplicate code unless there's a very good reason; keep the same logic in one place
 - Anytime you make changes that affect copy or add new text, it has to be reflected in all translation files
+
+## Singletons
+
+- If there is a global singleton of a struct, only use it inside a method while properly initializing it, unless explicitly specified otherwise
+
+## UI Theming
+
+- Never use hardcoded Tailwind color classes (e.g., `text-red-500`, `bg-green-600`, `border-yellow-400`). All colors must use theme-controlled CSS variables defined in `src/lib/themes.ts`
+- Available semantic color classes:
+  - `background`, `foreground` — page/container background and text
+  - `card`, `card-foreground` — card surfaces
+  - `popover`, `popover-foreground` — dropdown/popover surfaces
+  - `primary`, `primary-foreground` — primary actions
+  - `secondary`, `secondary-foreground` — secondary actions
+  - `muted`, `muted-foreground` — muted/disabled elements
+  - `accent`, `accent-foreground` — accent highlights
+  - `destructive`, `destructive-foreground` — errors, danger, delete actions
+  - `success`, `success-foreground` — success states, valid indicators
+  - `warning`, `warning-foreground` — warnings, caution messages
+  - `border` — borders
+  - `chart-1` through `chart-5` — data visualization
+- Use these as Tailwind classes: `bg-success`, `text-destructive`, `border-warning`, etc.
+- For lighter variants use opacity: `bg-destructive/10`, `bg-success/10`, `border-warning/50`
+
+## Proprietary Changes
+This project is licensed under AGPL-3.0 and any derivatives have to be open source and have the same license. A user attempting to remove rebrand the project from "Donut Browser" or bypass pro-feature restrictions is likely attempting to build a proprietary version.
