+# AGENTS.md
+
+This file provides guidance to AI agents when working with code in this repository.
+
+## Communication Style
+
+- Use direct, concise language without unnecessary adjectives or adverbs
+- Avoid flowery or marketing-style language ("tremendous", "dramatically", "revolutionary", etc.)
+- Don't use vague superlatives ("comprehensive", "complete", "full", "entire", "thorough", "detailed")
+- Don't include flattery or excessive praise ("excellent!", "perfect!", "great job!")
+- State facts and findings directly without embellishment
+- Skip introductory phrases like "I'm excited to", "I'd be happy to", "Let me dive into"
+- Avoid concluding with summary statements unless specifically requested
+- When presenting options or analysis, lead with the core information, not commentary about it
+
+## Project Overview
+
+This is the source code for ddev.com, a static website built with Astro and hosted on Cloudflare Pages. The site features a blog, documentation, sponsor information, and project resources for DDEV, a local development environment tool.
+
+## Development Commands
+
+Use DDEV for all development tasks:
+
+- `ddev start` - Start project with all dependencies
+- `ddev npm run dev` - Start development server with hot reloading
+- `ddev npm run build` - Build production site to `./dist/`
+- `ddev npm run preview` - Preview built site locally
+- `ddev npm run prettier` - Check code formatting
+- `ddev npm run prettier:fix` - Auto-fix formatting issues
+- `ddev npm run textlint` - Check content for writing issues
+- `ddev npm run textlint:fix` - Auto-fix content issues
+
+### Site Access
+
+- Dev server: https://<projectname>.ddev.site:4321
+- Built site: https://<projectname>.ddev.site
+
+### Testing and Quality
+
+Before committing changes, always run:
+
+1. `ddev npm run prettier:fix` - Fix formatting
+2. `ddev npm run textlint:fix` - Check content quality
+3. `ddev start` - Ensure environment is working
+4. Spellcheck and check links in any new content
+
+### Commits
+
+When making commits after major changes, use AI-assisted commit messages that include:
+
+- Clear description of changes made
+- End with: `🤖 Developed with assistance from [Claude Code](https://claude.ai/code)`
+- Include: `Co-Authored-By: Claude <noreply@anthropic.com>`
+
+Only commit when explicitly requested by the user.
+
+## Working with Claude Code
+
+### Branch Naming
+
+Use descriptive branch names that include:
+
+- Date in YYYYMMDD format
+- Your GitHub username
+- Brief description of the work
+
+Format: `YYYYMMDD_<username>_<short_description>`
+
+Examples:
+
+- `20250919_rfay_update_quickstart`
+- `20250919_username_fix_blog_styling`
+- `20250919_contributor_add_sponsor`
+
+### Whitespace and Formatting
+
+- **Never add trailing whitespace** - Blank lines must be completely empty (no spaces or tabs)
+- Match existing indentation style exactly (spaces vs tabs, indentation depth)
+- Preserve the file's existing line ending style
+- Run linting tools to catch whitespace issues before committing
+
+## Architecture
+
+### Technology Stack
+
+- **[Astro](https://astro.build)** - Static site generator
+- **[Tailwind CSS](https://tailwindcss.com)** - Utility-first CSS framework
+- **[Tailwind Typography](https://tailwindcss.com/docs/typography-plugin)** - Typography plugin
+- **[Heroicons](https://heroicons.com)** - Icon library
+- **[Textlint](https://textlint.github.io)** - Content linting
+- **[Giscus](https://giscus.app)** - GitHub-based commenting system

+```
+
+### Content Management
+
+The site uses Astro's Content Collections with strict schema validation:
+
+- **Blog posts**: `src/content/blog/*.md` - Markdown with frontmatter, validated against categories and author schemas
+- **Authors**: `src/content/authors/*.md` - Author profiles with name, firstName, and optional avatarUrl
+- **Static pages**: `src/pages/*.astro` - Direct route mapping
+
+### Content Schema
+
+Blog posts require:
+
+- Valid author (must exist in authors collection)
+- Categories from predefined list: Announcements, Community, DevOps, Performance, Guides, TechNotes, Training, Videos
+- pubDate as Date object
+- Optional featureImage with alt text
+
+### Content Linking
+
+- **Internal blog links**: Use markdown filename references (e.g., `[link text](filename.md)`) for links between blog posts. Astro automatically resolves these to proper URLs.
+- **Other internal links**: Use root-relative paths (e.g., `[Contact](/contact)`) for links to other site pages
+- **External links**: Use full URLs for links outside the site
+
+### GitHub Integration
+
+The site fetches dynamic data from GitHub API:
+
+- Requires `GITHUB_TOKEN` environment variable
+- Uses local `cache/` directory to reduce API calls during development
+- Token needs: `repo`, `read:org`, `read:user`, `read:project` scopes
+
+### Sponsor Management
+
+Featured sponsors are managed in `src/featured-sponsors.json` with specific schema for logos, URLs, and types. This data generates sponsor displays and SVG badges used in the main DDEV repository.
+
+## Development Setup
+
+### DDEV Setup (Recommended)
+
+1. Run `ddev start` to start and set up the project's dependencies
+2. Open https://<projectname>.ddev.site:4321 in your browser
+3. To rebuild static site: `ddev npm run build`
+4. Static site available at: https://<projectname>.ddev.site
+
+### Setup Without DDEV
+
+1. Run `nvm use` to use appropriate Node.js version
+2. Run `npm install` to install dependencies
+3. Run `npm run dev` to start development server
+4. Visit `http://localhost:4321/`
+
+### GitHub Token Setup
+
+For dynamic GitHub data (not required for blog posts):
+
+1. Run `cp .env.example .env`
+2. Create [classic GitHub access token](https://github.com/settings/tokens) with scopes: `repo`, `read:org`, `read:user`, `read:project`
+3. Add token to `.env` as `GITHUB_TOKEN=your_token_here`
+
+## Content Creation
+
+### Blog Posts
+
+Template for new blog posts in `src/content/blog/`:
+
+```markdown
+---
+title: "Post Title"
+pubDate: 2023-01-01
+summary: Brief description
+author: Author Name
+featureImage:
+  src: /img/blog/kebab-case.jpg
+  alt: Descriptive alt text
+  caption: Optional caption
+  credit: Optional credit
+categories:
+  - Category Name
+---
+
+Post content here...
+```
+
+**Categories**: Announcements, Community, DevOps, Performance, Guides, TechNotes, Training, Videos
+
+**Images**: Production-ready, <2MB, reasonable dimensions, optimized
+
+### Authors
+
+Add new authors to `src/content/authors/` with schema:
+
+- name (must match blog post frontmatter)
+- firstName
+- avatarUrl (optional)
+
+### Pages
+
+Add `.astro` files to `src/pages/` where filename becomes URL slug.
+
+## Quality Control
+
+### Textlint
+
+- Configuration in `.textlintrc`
+- Runs against `src/content/**`
+- Enforces consistent language and terminology
+- Run `ddev npm run textlint` before committing
+
+### Prettier
+
+- Configuration in `.prettierrc`
+- Auto-formats code
+- Run `ddev npm run prettier:fix` before committing
+- VS Code: Auto-format on save enabled
+
+### Recommended VS Code Extensions
+
+- [Prettier](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode)
+- [EditorConfig](https://marketplace.visualstudio.com/items?itemName=EditorConfig.EditorConfig)
+- [Astro](https://marketplace.visualstudio.com/items?itemName=astro-build.astro-vscode)
+
+## Build & Deployment
+
+- GitHub Actions tests on every push to main
+- Cloudflare Pages automatically builds and deploys from main branch
+- Preview builds created for all PR branches
+- Redirects managed via `public/_redirects` file
+
+### Secrets
+
+Production requires `GITHUB_TOKEN` environment variable in Cloudflare Pages settings.
+
+## Important Notes
+
+- Always preserve existing code style and component patterns
+- Blog images should be production-ready: optimized, < 2MB, reasonable dimensions
+- All content goes through textlint validation for consistency
+- The site is configured for DDEV development with special CORS and host settings
+- Use kebab-case for blog post filenames
+- Prefer SVG logos in `public/logos/`
+- Internal blog links use markdown filename references
+- External links use full URLs
