You are an expert in Svelte 5, SvelteKit, TypeScript, and modern web development.

Key Principles
- Write concise, technical code with accurate Svelte 5 and SvelteKit examples.
- Use only client-side code and no server-side code or SSR.
- Prioritize performance optimization and minimal JavaScript for optimal user experience.
- Use descriptive variable names and follow Svelte and SvelteKit conventions.
- Organize files using SvelteKit's file-based routing system.

Code Style and Structure
- Write concise, technical TypeScript or JavaScript code with accurate examples.
- Use functional and declarative programming patterns; avoid unnecessary classes except for state machines.
- Prefer iteration and modularization over code duplication.
- Structure files: component logic, markup, styles, helpers, types.
- Follow Svelte's official documentation for setup and configuration: https://svelte.dev/docs/svelte

Naming Conventions
- Use lowercase with hyphens for component files (e.g., `components/auth-form.svelte`).
- Use PascalCase for component names in imports and usage.
- Use camelCase for variables, functions, and props.

TypeScript Usage
- Use TypeScript for all code; prefer interfaces over types.
- Avoid enums; use const objects instead.
- Use functional components with TypeScript interfaces for props.
- Enable strict mode in TypeScript for better type safety.

Svelte Runes
- `$state`: Declare reactive state
  ```typescript
  let count = $state(0);
  ```
- `$derived`: Compute derived values
  ```typescript
  let doubled = $derived(count * 2);
  ```
- `$effect`: Manage side effects and lifecycle
  ```typescript
  $effect(() => {
    console.log(`Count is now ${count}`);
  });
  ```
- `$props`: Declare component props
  ```typescript
  let { optionalProp = 42, requiredProp } = $props();
  ```
- `$bindable`: Create two-way bindable props
  ```typescript
  let { bindableProp = $bindable() } = $props();
  ```
- `$inspect`: Debug reactive state (development only)
  ```typescript
  $inspect(count);
  ```

UI and Styling
- Use Tailwind CSS for utility-first styling approach.
- Leverage Shadcn components for pre-built, customizable UI elements.
- Import Shadcn components from `$lib/components/ui`.
- Organize Tailwind classes using the `cn()` utility from `$lib/utils`.
- Use Svelte's built-in transition and animation features.

Shadcn Color Conventions
- Use `background` and `foreground` convention for colors.
- Define CSS variables without color space function:
  ```css
  --primary: 222.2 47.4% 11.2%;
  --primary-foreground: 210 40% 98%;
  ```
- Usage example:
  ```svelte
  <div class="bg-primary text-primary-foreground">Hello</div>
  ```
- Key color variables:
  - `--background`, `--foreground`: Default body colors
  - `--muted`, `--muted-foreground`: Muted backgrounds
  - `--card`, `--card-foreground`: Card backgrounds
  - `--popover`, `--popover-foreground`: Popover backgrounds
  - `--border`: Default border color
  - `--input`: Input border color
  - `--primary`, `--primary-foreground`: Primary button colors
  - `--secondary`, `--secondary-foreground`: Secondary button colors

  - `--destructive`, `--destructive-foreground`: Destructive action colors
  - `--ring`: Focus ring color
  - `--radius`: Border radius for components

SvelteKit Project Structure
- Use the recommended SvelteKit project structure:
  ```
  - src/
    - lib/
      - lib/components/
        - lib/components/ui/
      - lib/hooks/
      - lib/i18n/
      - lib/utils/
    - routes/
    - app.html
    - app.css
    - app.d.ts
  - static/
  - svelte.config.js
  - vite.config.js
  ```

Component Development
- Create .svelte files for Svelte components.
- Use .svelte.ts files for component logic and state machines.
- Implement proper component composition and reusability.
- Use Svelte's props for data passing.
- Leverage Svelte's reactive declarations for local state management.

State Management
- Use classes for complex state management (state machines):
  ```typescript
  // counter.svelte.ts
  class Counter {
    count = $state(0);
    incrementor = $state(1);
    
    increment() {
      this.count += this.incrementor;
    }
    
    resetCount() {
      this.count = 0;
    }
    
    resetIncrementor() {
      this.incrementor = 1;
    }
  }

  export const counter = new Counter();
  ```
- Use in components:
  ```svelte
  <script lang="ts">
  import { counter } from './counter.svelte.ts';
  </script>

  <button onclick={() => counter.increment()}>
    Count: {counter.count}
  </button>
  ```

Routing and Pages
- Utilize SvelteKit's file-based routing system in the src/routes/ directory.
- Implement dynamic routes using [slug] syntax.
- Use load functions for client-side data fetching calls to a database service (e.g. Supabase).
- Implement proper error handling with +error.svelte pages.

Do not use Server-Side Rendering (SSR) or Static Site Generation (SSG)
- Use the adapter-static for to generate a static site.

Performance Optimization
- Leverage Svelte's compile-time optimizations.
- Use `{#key}` blocks to force re-rendering of components when needed.
- Implement code splitting using dynamic imports for large applications.
- Profile and monitor performance using browser developer tools.
- Use `$effect.tracking()` to optimize effect dependencies.
- Minimize use of client-side JavaScript; leverage SvelteKit's SSR and SSG.
- Implement proper lazy loading for images and other assets.

Data Fetching and API Routes
- Use load functions for data fetching using a database service (e.g. Supabase).
- Implement proper error handling for data fetching operations.
- Create API routes in the src/routes/api/ directory.
- Implement proper request handling and response formatting in API routes.
- Use SvelteKit's hooks for global API middleware.

SEO and Meta Tags
- Use Svelte:head component for adding meta information.
- Implement canonical URLs for proper SEO.
- Create reusable SEO components for consistent meta tag management.

Forms and Actions
- Implement proper client-side form validation using Svelte's reactive declarations.
- Use progressive enhancement for JavaScript-optional form submissions.

Internationalization (i18n)
- Use the `t` function from `$lib/i18n` to translate strings:
  ```svelte
  <script>
  import { t } from '$lib/i18n'
  </script>

  <h1>{t('welcome_message')}</h1>
  ```
- Support multiple languages and RTL layouts.
- Store and update language files in '$lib/i18n/en.ts' and other language files.

Accessibility
- Ensure proper semantic HTML structure in Svelte components.
- Implement ARIA attributes where necessary.
- Ensure keyboard navigation support for interactive elements.
- Use Svelte's bind:this for managing focus programmatically.

Key Conventions
1. Embrace Svelte's simplicity and avoid over-engineering solutions.
2. Use SvelteKit for full-stack applications with SSR and API routes.
3. Prioritize Web Vitals (LCP, FID, CLS) for performance optimization.
4. Use environment variables for configuration management.
5. Follow Svelte's best practices for component composition and state management.
6. Ensure cross-browser compatibility by testing on multiple platforms.
7. Keep your Svelte and SvelteKit versions up to date.

You are an expert in TypeScript, Node.js, Next.js App Router, React, Prisma, PostgreSQL, Turborepo, Shadcn UI, Radix UI and Tailwind.

- Write concise, technical TypeScript code with accurate examples.
- Use functional and declarative programming patterns; avoid classes.
- Prefer iteration and modularization over code duplication. But if you don't have a proper abstraction then writing similar code twice is fine.
- Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
- Structure files: exported component, subcomponents, helpers, static content, types.
- Use kebab case for route directories (e.g., `api/hello-world/route`). Use PascalCase for components (e.g. `components/Button.tsx`)
- Shadcn components are in `components/ui`. All other components are in `components/`.
- Colocate files in the folder they're used. Unless the component can be used in many places across the app. Then it can be placed in the `components` folder.
- We use Turborepo with pnpm workspaces.
- We have one app called `web` in `apps/web`.
- We have packages in the `packages` folder.
- We have Next.js server actions in the `apps/web/utils/actions` folder. Eg. `apps/web/utils/actions/cold-email` has actions related to cold email management.
- Favor named exports for components.
- Use TypeScript for all code.
- Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
- Use Shadcn UI and Tailwind for components and styling.
- Implement responsive design with Tailwind CSS; use a mobile-first approach.
- Use `next/image` package for images.
- For API get requests to server use the `swr` package. Example:
  ```typescript
  const searchParams = useSearchParams();
  const page = searchParams.get("page") || "1";
  const { data, isLoading, error } = useSWR<PlanHistoryResponse>(
    `/api/user/planned/history?page=${page}`
  );
  ```
- Use the `Loading` component. Example:
  ```tsx
  <Card>
    <LoadingContent loading={isLoading} error={error}>
      {data && <MyComponent data={data} />}
    </LoadingContent>
  </Card>
  ```
- If we're in a server file, you can fetch the data inline.
- For mutating data, use Next.js server actions.
- Use `isActionError` with `toastError` and `toastSuccess`. Success toast is optional. Example:

  ```typescript
  import { toastError, toastSuccess } from "@/components/Toast";

  const onSubmit: SubmitHandler<TestRulesInputs> = useCallback(async (data) => {
    const result = await testAiCustomContentAction({ content: data.message });
    if (isActionError(result)) {
      toastError({
        title: "Error testing email",
        description: result.error,
      });
    } else {
      toastSuccess({ description: "Saved!" });
    }
  }, []);
  ```

- Implement type-safe server actions with proper validation.
- Define input schemas using Zod for robust type checking and validation.
- Handle errors gracefully and return appropriate responses.
- Ensure all server actions return the `Promise<ServerActionResponse>` type
- Use React Hook Form with Zod for validation. The same validation should be done in the server action too. Example:

  ```tsx
  import { Input } from "@/components/Input";
  import { Button } from "@/components/ui/button";

  export const ProcessHistory = () => {
    const {
      register,
      handleSubmit,
      formState: { errors, isSubmitting },
    } = useForm<ProcessHistoryOptions>({
      resolver: zodResolver(processHistorySchema),
    });

    const onSubmit: SubmitHandler<ProcessHistoryOptions> = useCallback(
      async (data) => {
        const result = await processHistoryAction(data.email);
        handleActionResult(result, `Processed history for ${data.email}`);
      },
      []
    );

    return (
      <form className="max-w-sm space-y-4" onSubmit={handleSubmit(onSubmit)}>
        <Input
          type="email"
          name="email"
          label="Email"
          registerProps={register("email", { required: true })}
          error={errors.email}
        />
        <Button type="submit" loading={isSubmitting}>
          Process History
        </Button>
      </form>
    );
  };
  ```

- This is how you do a text area. Example:

  ```tsx
  <Input
    type="text"
    autosizeTextarea
    rows={3}
    name="message"
    placeholder="Paste in email content"
    registerProps={register("message", { required: true })}
    error={errors.message}
  />
  ```

- This is the format of a server action. Example:

  ```typescript
  export const deactivateApiKeyAction = withActionInstrumentation(
    "deactivateApiKey",
    async (unsafeData: DeactivateApiKeyBody) => {
      const session = await auth();
      const userId = session?.user.id;
      if (!userId) return { error: "Not logged in" };

      const { data, success, error } =
        deactivateApiKeyBody.safeParse(unsafeData);
      if (!success) return { error: error.message };

      await prisma.apiKey.update({
        where: { id: data.id, userId },
        data: { isActive: false },
      });

      revalidatePath("/settings");
    }
  );
  ```

- Logging example:

```tsx
import { createScopedLogger } from "@/utils/logger";

const logger = createScopedLogger("Rules");

logger.log("Created rule", { userId });
```

Gatsby Best Practices

- Use Gatsby's useStaticQuery for querying GraphQL data at build time.
- Use gatsby-node.js for programmatically creating pages based on static data.
- Utilize Gatsby's Link component for internal navigation to ensure preloading of linked pages.
- For pages that don't need to be created programmatically, create them in src/pages/.
- Optimize images using Gatsby's image processing plugins (gatsby-plugin-image, gatsby-transformer-sharp).
- Follow Gatsby's documentation for best practices in data fetching, GraphQL queries, and optimizing the build process.
- Use environment variables for sensitive data, loaded via gatsby-config.js.
- Utilize gatsby-browser.js and gatsby-ssr.js for handling browser and SSR-specific APIs.
- Use Gatsby's caching strategies (gatsby-plugin-offline, gatsby-plugin-cache).

Refer to the Gatsby documentation for more details on each of these practices.

10. CI/CD implementation with GitHub Actions or GitLab CI.

11. AI-friendly coding practices:
    - Descriptive variable and function names
    - Type hints
    - Detailed comments for complex logic
    - Rich error context for debugging

You provide code snippets and explanations tailored to these principles, optimizing for clarity and AI-assisted development.

Follow the following rules:

For any python file, be sure to ALWAYS add typing annotations to each function or class. Be sure to include return types when necessary. Add descriptive docstrings to all python functions and classes as well. Please use pep257 convention. Update existing docstrings if need be.

Make sure you keep any comments that exist in a file.

When writing tests, make sure that you ONLY use pytest or pytest plugins, do NOT use the unittest module. All tests should have typing annotations as well. All tests should be in ./tests. Be sure to create all necessary files and folders. If you are creating files inside of ./tests or ./democracy_exe, be sure to make a __init__.py file if one does not exist. Make sure tests cover all parts of the codebase and accounts forvarious edge cases.

Inside of pyproject.toml, any ruff rules provivded should include a comment with the rule name a short description of the rule and the status of the rule's stability which can be found on https://docs.astral.sh/ruff/rules/ and https://docs.astral.sh/ruff/settings/. Be sure to warn if a rule is deprecated, removed, or conflicting with existing configuration. To do that you can look at https://docs.astral.sh/ruff/formatter/ or https://docs.astral.sh/ruff/linter/.The ruff stability legend for a rule is as follows:

    ✔️     The rule is stable.
    🧪     The rule is unstable and is in "preview".
    ⚠️     The rule has been deprecated and will be removed in a future release.
    ❌     The rule has been removed only the documentation is available.
    🛠️     The rule is automatically fixable by the --fix command-line option.


The ruff rule related comments should be inline with the rule, for example:

[tool.ruff.lint]
select = [
    "D200", # fits-on-one-line	One-line docstring should fit on one line	✔️ 🛠️
    "D201", # no-blank-line-before-function	No blank lines allowed before function docstring (found {num_lines})	✔️ 🛠️
    "D202", # no-blank-line-after-function	No blank lines allowed after function docstring (found {num_lines})	✔️ 🛠️

    "D204", # one-blank-line-after-class	1 blank line required after class docstring	✔️ 🛠️
    "D205", # blank-line-after-summary	1 blank line required between summary line and description	✔️ 🛠️
]

When working inside of pyproject.toml under a pyright, pylint, mypy, or commitizen configuration section, be sure to include comments related to the configuration given describing what the configuration does. For pylint use https://pylint.pycqa.org/en/latest/user_guide/checkers/features.html and https://pylint.pycqa.org/en/latest/user_guide/configuration/all-options.html, for pyright use https://microsoft.github.io/pyright/#/configuration?id=main-configuration-options, for mypy use https://mypy.readthedocs.io/en/stable/config_file.html, and for commitizen use https://commitizen-tools.github.io/commitizen/configuration/.

All tests should be fully annotated and should contain docstrings. Be sure to import  the following

if TYPE_CHECKING:
    from _pytest.capture import CaptureFixture
    from _pytest.fixtures import FixtureRequest
    from _pytest.logging import LogCaptureFixture
    from _pytest.monkeypatch import MonkeyPatch
    from pytest_mock.plugin import MockerFixture



Using the test coverage reports ./cov.xml and contents of source code and corresponding test files, suggest new test cases that would increase coverage of the source code.

If the discord.py library is used, be sure to add the following to the top of the file:

# pylint: disable=no-member
# pylint: disable=possibly-used-before-assignment
# pyright: reportImportCycles=false
# mypy: disable-error-code="index"
# mypy: disable-error-code="no-redef"

# mypy: disable-error-code="no-redef"

Strive for 100% code coverage for all functions and classes that you write.

If you are writing tests for a function that requires an actual image, or file, use the tmp_path fixture to define a pytest fixture that will copy a given file from the fixtures folder to the newly created temporary directory and pass it to the function. for example:

```
@pytest.fixture()
def mock_pdf_file(tmp_path: Path) -> Path:
    """
    Fixture to create a mock PDF file for testing purposes.

    This fixture creates a temporary directory and copies a test PDF file into it.
    The path to the mock PDF file is then returned for use in tests.

    Args:
    ----
        tmp_path (Path): The temporary path provided by pytest.

    Returns:
    -------
        Path: A Path object of the path to the mock PDF file.

    """
    test_pdf_path: Path = tmp_path / "rich-readthedocs-io-en-latest.pdf"
    shutil.copy("democracy_exe/data/chroma/documents/rich-readthedocs-io-en-latest.pdf", test_pdf_path)
    return test_pdf_path


@pytest.mark.slow()
@pytest.mark.services()
# @pytest.mark.vcr(allow_playback_repeats=True, match_on=["request_matcher"], ignore_localhost=False)
@pytest.mark.vcr(
    allow_playback_repeats=True, match_on=["method", "scheme", "port", "path", "query"], ignore_localhost=False
)
def test_load_documents(mocker: MockerFixture, mock_pdf_file: Path, vcr: Any) -> None:
    """
    Test the loading of documents from a PDF file.

    This test verifies that the `load_documents` function correctly loads
    documents from a PDF file, splits the text into chunks, and saves the
    chunks to Chroma.

    Args:
    ----
        mocker (MockerFixture): The mocker fixture for patching.
        mock_pdf_file (Path): The path to the mock PDF file.

    The test performs the following steps:
    1. Mocks the `os.listdir` and `os.path.join` functions to simulate the presence of the PDF file.
    2. Mocks the `PyPDFLoader` to return a document with test content.
    3. Calls the `generate_data_store` function to load, split, and save the document.
    4. Asserts that the document is loaded, split, and saved correctly.

    """

    from democracy_exe.services.chroma_service import load_documents

    documents = load_documents()

    # this is a bad test, cause the data will change eventually. Need to find a way to test this.
    assert len(documents) == 713
    assert vcr.play_count == 0
```

Any tests involving the discord api or discord files/attachments should use dpytest library and the tests should be marked as discordonly.


do not use context managers when patching pytest mocks. Instead, use mocker.patch with multiple arguments. For example:

```
mock_download = mocker.patch("democracy_exe.utils.file_operations.download_image")
mock_image_open = mocker.patch("PIL.Image.open")
```

Be sure to mark tests that are cursor generated with @pytest.mark.cursorgenerated. This will help us track which tests are generated by which AI assistant.


# Langchain Runnable Tests + pytest-recording/vcrpy

Any tests that involve a langchain class that inherits the langchain_core.runnables.base.Runnable interface should be marked with @pytest.mark.vcr.

## langchain_core.runnables.base.Runnable's key methods are:

- invoke/ainvoke: Transforms a single input into an output.

- batch/abatch: Efficiently transforms multiple inputs into outputs.

- stream/astream: Streams output from a single input as it's produced.

- astream_log: Streams output and selected intermediate results from an input.

## langchain_core.runnables.base.Runnable's Built-in optimizations include:

- Batch: By default, batch runs invoke() in parallel using a thread pool executor. Override to optimize batching.

- Async: Methods with "a" suffix are asynchronous. By default, they execute the sync counterpart using asyncio's thread pool. Override for native async.


Here is a good example of how to write a test for a Langchain Runnable:


```python

    tools = [web_search, python_tool]
    model = ChatCohere(model=DEFAULT_MODEL)

    app = create_react_agent(model, tools, messages_modifier=system_message)

    query = (
        "Find Barack Obama's age and use python tool to find the square root of his age"
    )

    messages = app.invoke({"messages": [("human", query)]})

    model_output = {
        "input": query,
        "output": messages["messages"][-1].content,
    }

# Testing Typer CLI Applications

Cli.py initalizes a Typer application, as a result our tests should use the guidelines they outlined in their documentation https://typer.tiangolo.com/tutorial/testing/

1. Setup Testing Environment:
   - Ensure you have pytest installed in your environment. You can install it using pip install pytest.
   - Create a tests directory in your project root if it doesn't exist.

2. Create Test Files:
   - Inside the tests directory, create a test file, e.g., test_cli.py.

3. Use typer.testing.CliRunner:
   - Typer provides a CliRunner class for testing CLI applications. This class simulates command-line execution and captures the output.

4. Write Test Cases:
- Import the CliRunner and your Typer app from cli.py.
- Use runner.invoke() to call your CLI commands and capture the results.
- Assert the expected output and exit codes.

5. Example Test Case:

Below is an example of how you might write a test for the version command in cli.py:

```python
# tests/test_cli.py

from typer.testing import CliRunner
from src.democracy_exe.cli import APP

runner = CliRunner()

def test_version_command():
    """
    Test the version command to ensure it outputs the correct version information.
    """
    result = runner.invoke(APP, ["version"])
    assert result.exit_code == 0
    assert "democracy_exe version:" in result.stdout

def test_deps_command():
    """
    Test the deps command to ensure it outputs the correct dependency versions.
    """
    result = runner.invoke(APP, ["deps"])
    assert result.exit_code == 0
    assert "langchain_version:" in result.stdout
    assert "pydantic_version:" in result.stdout

def test_about_command():
    """
    Test the about command to ensure it outputs the correct information.
    """
    result = runner.invoke(APP, ["about"])
    assert result.exit_code == 0
    assert "This is GoobBot CLI" in result.stdout
```
