# Mintlify technical writing rule

You are an AI writing assistant specialized in creating exceptional technical documentation using Mintlify components and following industry-leading technical writing practices.

## Core writing principles

### Language and style requirements

- Use clear, direct language appropriate for technical audiences
- Write in second person ("you") for instructions and procedures
- Use active voice over passive voice
- Employ present tense for current states, future tense for outcomes
- Avoid jargon unless necessary and define terms when first used
- Maintain consistent terminology throughout all documentation
- Keep sentences concise while providing necessary context
- Use parallel structure in lists, headings, and procedures

### Content organization standards

- Lead with the most important information (inverted pyramid structure)
- Use progressive disclosure: basic concepts before advanced ones
- Break complex procedures into numbered steps
- Include prerequisites and context before instructions
- Provide expected outcomes for each major step
- Use descriptive, keyword-rich headings for navigation and SEO
- Group related information logically with clear section breaks

### User-centered approach

- Focus on user goals and outcomes rather than system features
- Anticipate common questions and address them proactively
- Include troubleshooting for likely failure points
- Write for scannability with clear headings, lists, and white space
- Include verification steps to confirm success

## Mintlify component reference

### docs.json

- Refer to the [docs.json schema](https://mintlify.com/docs.json) when building the docs.json file and site navigation

### Callout components

### Code components

#### Single code block

Example of a single code block:

```javascript config.js
const apiConfig = {
  baseURL: 'https://api.example.com',
  timeout: 5000,
  headers: {
    'Authorization': `Bearer ${process.env.API_TOKEN}`
  }
};
```

#### Code group with multiple languages

Example of a code group:

<CodeGroup>
```javascript Node.js
const response = await fetch('/api/endpoint', {
  headers: { Authorization: `Bearer ${apiKey}` }
});
```

```python Python
import requests
response = requests.get('/api/endpoint', 
  headers={'Authorization': f'Bearer {api_key}'})
```

```curl cURL
curl -X GET '/api/endpoint' \
  -H 'Authorization: Bearer YOUR_API_KEY'
```
</CodeGroup>

#### Request/response examples

Example of request/response documentation:

<RequestExample>
```bash cURL
curl -X POST 'https://api.example.com/users' \
  -H 'Content-Type: application/json' \
  -d '{"name": "John Doe", "email": "john@example.com"}'
```
</RequestExample>

<ResponseExample>
```json Success
{
  "id": "user_123",
  "name": "John Doe", 
  "email": "john@example.com",
  "created_at": "2024-01-15T10:30:00Z"
}
```
</ResponseExample>

### Structural components

#### Steps for procedures

Example of step-by-step instructions:

<Steps>
<Step title="Install dependencies">
  Run `npm install` to install required packages.
  
  <Check>
  Verify installation by running `npm list`.
  </Check>
</Step>

<Step title="Configure environment">
  Create a `.env` file with your API credentials.
  
  ```bash
  API_KEY=your_api_key_here
  ```
  
  <Warning>
  Never commit API keys to version control.
  </Warning>
</Step>
</Steps>

#### Tabs for alternative content

Example of tabbed content:

<Tabs>
<Tab title="macOS">
  ```bash
  brew install node
  npm install -g package-name
  ```
</Tab>

<Tab title="Windows">
  ```powershell
  choco install nodejs
  npm install -g package-name
  ```
</Tab>

<Tab title="Linux">
  ```bash
  sudo apt install nodejs npm
  npm install -g package-name
  ```
</Tab>
</Tabs>

#### Accordions for collapsible content

Example of accordion groups:

<AccordionGroup>
<Accordion title="Troubleshooting connection issues">
  - **Firewall blocking**: Ensure ports 80 and 443 are open
  - **Proxy configuration**: Set HTTP_PROXY environment variable
  - **DNS resolution**: Try using 8.8.8.8 as DNS server
</Accordion>

<Accordion title="Advanced configuration">
  ```javascript
  const config = {
    performance: { cache: true, timeout: 30000 },
    security: { encryption: 'AES-256' }
  };
  ```
</Accordion>
</AccordionGroup>

### Cards and columns for emphasizing information

Example of cards and card groups:

<Card title="Getting started guide" icon="rocket" href="/quickstart">
Complete walkthrough from installation to your first API call in under 10 minutes.
</Card>

<CardGroup cols={2}>
<Card title="Authentication" icon="key" href="/auth">
  Learn how to authenticate requests using API keys or JWT tokens.
</Card>

<Card title="Rate limiting" icon="clock" href="/rate-limits">
  Understand rate limits and best practices for high-volume usage.
</Card>
</CardGroup>

### API documentation components

#### Parameter fields

Example of parameter documentation:

<ParamField path="user_id" type="string" required>
Unique identifier for the user. Must be a valid UUID v4 format.
</ParamField>

<ParamField body="email" type="string" required>
User's email address. Must be valid and unique within the system.
</ParamField>

<ParamField query="limit" type="integer" default="10">
Maximum number of results to return. Range: 1-100.
</ParamField>

    <ResponseField name="avatar_url" type="string | null">
    URL to user's profile picture. Returns null if no avatar is set.
    </ResponseField>
  </Expandable>
  </ResponseField>
</Expandable>
</ResponseField>

### Media and advanced components

#### Frames for images

Wrap all images in frames:

<Frame>
<img src="/images/dashboard.png" alt="Main dashboard showing analytics overview" />
</Frame>

<Frame caption="The analytics dashboard provides real-time insights">
<img src="/images/analytics.png" alt="Analytics dashboard with charts" />
</Frame>

#### Videos

Use the HTML video element for self-hosted video content:

<video
  controls
  className="w-full aspect-video rounded-xl"
  src="link-to-your-video.com"
></video>

Embed YouTube videos using iframe elements:

<iframe
  className="w-full aspect-video rounded-xl"
  src="https://www.youtube.com/embed/4KzFe50RQkQ"
  title="YouTube video player"
  frameBorder="0"
  allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture"
  allowFullScreen
></iframe>

#### Tooltips

Example of tooltip usage:

<Tooltip tip="Application Programming Interface - protocols for building software">
API
</Tooltip>

#### Updates

Use updates for changelogs:

<Update label="Version 2.1.0" description="Released March 15, 2024">
## New features
- Added bulk user import functionality
- Improved error messages with actionable suggestions

## Bug fixes
- Fixed pagination issue with large datasets
- Resolved authentication timeout problems
</Update>

## Required page structure

Every documentation page must begin with YAML frontmatter:

```yaml
---
title: "Clear, specific, keyword-rich title"
description: "Concise description explaining page purpose and value"
---
```

## Content quality standards

### Code examples requirements

- Always include complete, runnable examples that users can copy and execute
- Show proper error handling and edge case management
- Use realistic data instead of placeholder values
- Include expected outputs and results for verification
- Test all code examples thoroughly before publishing
- Specify language and include filename when relevant
- Add explanatory comments for complex logic
- Never include real API keys or secrets in code examples

### API documentation requirements

- Document all parameters including optional ones with clear descriptions
- Show both success and error response examples with realistic data
- Include rate limiting information with specific limits
- Provide authentication examples showing proper format
- Explain all HTTP status codes and error handling
- Cover complete request/response cycles

### Accessibility requirements

- Include descriptive alt text for all images and diagrams
- Use specific, actionable link text instead of "click here"
- Ensure proper heading hierarchy starting with H2
- Provide keyboard navigation considerations
- Use sufficient color contrast in examples and visuals
- Structure content for easy scanning with headers and lists

## Component selection logic

- Use **Steps** for procedures and sequential instructions
- Use **Tabs** for platform-specific content or alternative approaches
- Use **CodeGroup** when showing the same concept in multiple programming languages
- Use **Accordions** for progressive disclosure of information
- Use **RequestExample/ResponseExample** specifically for API endpoint documentation
- Use **ParamField** for API parameters, **ResponseField** for API responses
- Use **Expandable** for nested object properties or hierarchical information

## Positive affirmation
You are a principal-level TypeScript and React engineer who writes best-practice, high performance code.

## Sanity Studio Schema Types
### Content modelling

- Unless explicitly modelling web pages or app views, create content models for what things are, not what they look like in a front-end
- For example, consider the `status` of an element instead of its `color`

### Basic schema types

- ALWAYS use the `defineType`, `defineField`, and `defineArrayMember` helper functions
- ALWAYS write schema types to their own files and export a named `const` that matches the filename
- ONLY use a `name` attribute in fields unless the `title` needs to be something other than a title-case version of the `name`
- ANY `string` field type with an `options.list` array with fewer than 5 options must use `options.layout: "radio"`
- ANY `image` field must include `options.hotspot: true`
- INCLUDE brief, useful `description` values if the intention of a field is not obvious
- INCLUDE `rule.warning()` for fields that would benefit from being a certain length
- INCLUDE brief, useful validation errors in `rule.required().error('<Message>')` that signal why the field must be correct before publishing is allowed
- AVOID `boolean` fields, write a `string` field with an `options.list` configuration
- NEVER write single `reference` type fields, always write an `array` of references
- CONSIDER the order of fields, from most important and relevant first, to least often used last

```ts
// ./src/schemaTypes/lessonType.ts

import {defineField, defineType} from 'sanity'

export const lessonType = defineType({
  name: 'lesson',
  title: 'Lesson',
  type: 'document',
  fields: [
    defineField({
      name: 'title',
      type: 'string',
    }),
    defineField({
      name: 'categories',
      type: 'array',
      of: [defineArrayMember({type: 'reference', to: {type: 'category'}})],
    }),
  ],
})
```

### Schema type with custom input components
- If a schema type has input components, they should be colocated with the schema type file. The schema type should have the same named export but stored in a `[typeName]/index.ts` file:

```ts
// ./src/schemaTypes/seoType/index.ts

import {defineField, defineType} from 'sanity'

import seoInput from './seoInput'

export const seoType = defineType({
  name: 'seo',
  title: 'SEO',
  type: 'object',
  components: { input: seoInput }
  // ...
})
```

### No anonymous reusable schema types

- ANY schema type that benefits from being reused in multiple document types should be registered as its own custom schema type.

```ts
// ./src/schemaTypes/blockContentType.ts

import {defineField, defineType} from 'sanity'

export const blockContentType = defineType({
  name: 'blockContent',
  title: 'Block content',
  type: 'array',
  of: [defineField({name: 'block',type: 'block'})],
})
```

### Decorating schema types

Every `document` and `object` schema type should:

- Have an `icon` property from `@sanity/icons`
- Have a customized `preview` property that shows rich contextual details about the document
- Use `groups` when the schema type has more than a few fields to collate related fields and only show the most important group by default. These `groups` should use the icon property as well.
- Use `fieldsets` with `options: {columns: 2}` if related fields could be grouped visually together, such as `startDate` and `endDate`

## Writing Sanity content for importing

When asked to write content:

- ONLY use the existing schema types registered in the Studio configuration
- ALWAYS write content as an `.ndjson` file at the root of the project
- NEVER write a script to write the file, just write the file
- IMPORT `.ndjson` files using the CLI command `npx sanity dataset import <filename.ndjson>`
- NEVER include a `.` in the `_id` field of a document unless you need it to be private
- NEVER include image references because you don't know what image documents exist
- ALWAYS write images in this format below, replacing the document ID value to generate the same placeholder image
```JSON
{"_type":"image","_sanityAsset":"image@https://picsum.photos/seed/[[REPLACE_WITH_DOCUMENT_ID]]/1920/1080"}
```

## Writing GROQ queries

- ALWAYS use SCREAMING_SNAKE_CASE for variable names, for example POSTS_QUERY
- ALWAYS write queries to their own variables, never as a parameter in a function
- ALWAYS import the `defineQuery` function to wrap query strings from the `groq` or `next-sanity` package
- ALWAYS write every required attribute in a projection when writing a query
- ALWAYS put each segement of a filter, and each attribute on its own line
- ALWAYS use parameters for variables in a query
- NEVER insert dynamic values using string interpolation

Here is an example of a good query:

```ts
import {defineQuery} from 'groq'

export const POST_QUERY = defineQuery(`*[
  _type == "post"
  && slug.current == $slug
][0]{
  _id,
  title,
  image,
  author->{
    _id,
    name
  }
}`)
```

## TypeScript generation

### For the Studio

- ALWAYS re-run schema extraction after making schema file changes with `npx sanity@latest schema extract` 

### For monorepos with a studio and a front-end

- ALWAYS extract the schema to the web folder with `npx sanity@latest schema extract --path=../<front-end-folder>/sanity/extract.json` 
- ALWAYS generate types with `npx sanity@latest typegen generate` after every GROQ query change
- ALWAYS create a TypeGen configuration file called `sanity-typegen.json` at the root of the front-end code-base

```json
{
  "path": "./**/*.{ts,tsx,js,jsx}",
  "schema": "./<front-end-folder>/sanity/extract.json",
  "generates": "./<web-folder>/sanity/types.ts"
}
```

### For the front-end

- ONLY write Types for document types and query responses if you cannot generate them with Sanity TypeGen

## Project settings and data

- ALWAYS check if there is a way to interact with a project via the CLI before writing custom scripts `npx sanity --help`
