Use them to give a substantive review.\n\nReview this PR and produce a single comment. Format:\n\n1.

Mention file names and what you see in the diff. Look for:\n   - Bugs or logic errors in the changed code\n   - Security issues (SQL injection, path traversal, XSS, command injection)\n   - Missing error handling or edge cases\n   - Breaking changes to existing APIs or behavior\n   - If UI text was added/changed, check if all 7 translation files (en, es, fr, ja, pt, ru, zh) in src/i18n/locales/ were updated\n   - If Tauri commands were added/removed, the unused-commands test in lib.rs needs updating\n3. **Suggestions** - Concrete improvements if any. Skip if the PR looks good.\n\nRules:\n- Be substantive. Review the actual diff, not just the description.\n- Do NOT nitpick formatting or style — the project has automated linting (biome + clippy + rustfmt).\n- Do NOT just summarize the PR description back to the user — they wrote it, they know what it says.\n- If the PR is good, say so briefly.\n- Never exceed 20 lines.")

-# Instructions for AI Agents

- 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.
+> **IMPORTANT**: CLAUDE.md and AGENTS.md must always be identical. If you update one, update the other.
+> After significant changes (new modules, renamed files, new directories), re-evaluate the Repository Structure below and update it if needed.

+
+## 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`

 ## 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

 ## UI Theming

- When modifying the UI, don't add random colors that are not controlled by `src/lib/themes.ts`
+- 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`

 ## Development Setup

-### Using Nix
-
-If you have [Nix](https://nixos.org/) installed, you can skip the manual setup below and simply run:
+### Using Nix (recommended)

 ```bash
-nix develop
-# or if you use direnv
-direnv allow
+nix run .#setup     # Install dependencies
+nix run .#tauri-dev  # Start development server
+nix run .#test       # Run all checks
 ```

-This will provide Node.js, Rust, and all necessary system libraries.
+Or enter the dev shell: `nix develop`

 ### Manual Setup

-Ensure you have the following dependencies installed:
-
- Node.js (see `.node-version` for exact version)
- pnpm package manager
- Latest Rust and Cargo toolchain
- [Tauri prerequisites guide](https://v2.tauri.app/start/prerequisites/).
-
-## Run Locally
-
-After having the above dependencies installed, proceed through the following steps to setup the codebase locally:
-
-1. **Fork the project** & [clone](https://docs.github.com/en/repositories/creating-and-managing-repositories/cloning-a-repository) it locally.
-
-2. **Create a new separate branch.**
-
-   ```bash
-   git checkout -b feature/my-feature-name
-   ```
-
-3. **Install frontend dependencies**
-
-   ```bash
-   pnpm install
-   ```
-
-4. **Start the development server**
-
-   ```bash
-   pnpm tauri dev
-   ```
-
-This will start the app for local development with live reloading.
-
-## Code Style & Quality
-
-We use several tools to maintain code quality:
-
- **Biome** for JavaScript/TypeScript linting and formatting
- **Clippy** for Rust linting
- **rustfmt** for Rust formatting
-
-### Before Committing
-
-Run these commands to ensure your code meets our standards:
+Requirements:
+- Node.js (see `.node-version`)
+- pnpm
+- Rust + Cargo (latest stable)
+- [Tauri v2 prerequisites](https://v2.tauri.app/start/prerequisites/)

 ```bash
-# Format and lint frontend code
-pnpm format:js
-
-# Format and lint Rust code
-pnpm format:rust
-
-# Run all linting
-pnpm lint
+git checkout -b feature/my-feature-name
+pnpm install
+pnpm tauri dev
 ```

-## Building
+## Quality Checks

-It is crucial to test your code before submitting a pull request. Please ensure that you can make a complete production build before you submit your code for merging.
+Run before every commit:

 ```bash
-# Build the frontend
-pnpm build
-
-# Build the backend
-cd src-tauri && cargo build
-
-# Build the Tauri application
-pnpm tauri build
+pnpm format && pnpm lint && pnpm test
 ```

-Make sure the build completes successfully without errors.
+This runs:
+- **Biome** — JS/TS linting and formatting
+- **Clippy + rustfmt** — Rust linting and formatting
+- **typos** — Spellcheck (allowlist in `_typos.toml`)
+- **CodeQL** — Security analysis (JS, Actions, Rust) — runs in CI
+- **Unit tests** — 330+ Rust tests
+- **Integration tests** — proxy, sync e2e

-## Testing
+### Running CodeQL locally

- Always test your changes on the target platform
- Verify that existing functionality still works
- Add tests for new features when possible
+```bash
+# Install: brew install codeql
+codeql pack download codeql/javascript-queries codeql/rust-queries
+
+# JavaScript
+codeql database create /tmp/codeql-js --language=javascript --source-root=.
+codeql database analyze /tmp/codeql-js --format=sarifv2.1.0 --output=/tmp/js.sarif codeql/javascript-queries
+
+# Rust
+codeql database create /tmp/codeql-rust --language=rust --source-root=.
+codeql database analyze /tmp/codeql-rust --format=sarifv2.1.0 --output=/tmp/rust.sarif codeql/rust-queries
+```
+
+## Key Rules
+
+- **Translations**: Any UI text changes must be reflected in all 7 locale files (`src/i18n/locales/`)
+- **Tauri commands**: If you modify Tauri commands, the `test_no_unused_tauri_commands` test will catch unused ones
+- **No hardcoded colors**: Use theme CSS variables (see `src/lib/themes.ts`), never Tailwind color classes like `text-red-500`
+- **No lock file changes**: Don't update `pnpm-lock.yaml` or `Cargo.lock` unless updating dependencies is the purpose of the PR
+- **AGPL-3.0**: This project is AGPL-licensed. Derivatives must be open source with the same license

 ## Pull Request Guidelines

-🎉 Now that you're ready to submit your code for merging, there are some points to keep in mind:
+- Fill the PR description template
+- Reference related issues (`Fixes #123` or `Refs #123`)
+- Include screenshots/videos for UI changes
+- Ensure "Allow edits from maintainers" is checked
