  ## What's included

  ### New blog post (`src/routes/blog/trackers-implemented-in-rust/`)
  - Covers 4 actively maintained trackers: aquatic, Torrust Tracker, Torrust-Actix, UNIT3D-Announce
  - Covers 5 historical/abandoned trackers: UDPT, Tyto, Rotten, bittorrent-client-tracker, Torshare
  - Each entry includes: repository, stars, license, status, key features, and implemented BEPs
  - Comparison table with columns: Project, Protocols, BEPs, License, Stars, Status
  - Trackers ordered by GitHub star count within each section
  - Neutral conclusion with no promotional language

  ### Banner image
  - `static/images/posts/trackers-implemented-in-rust/banner-rust-bitorrent-trackers.webp`

  ### Bug fix
  - Updated Torrust-Actix link in `src/lib/constants/constants.ts` and the blog post from `gbitt.info` to `https://www.torrust-actix.com/`

  ### Tooling / docs
  - `AGENTS.md`: improved blog post authoring instructions, fixed Markdown lint violations (MD010, MD036, MD001)
  - `.prettierrc.cjs`: added `*.md` override to prevent hard tabs in Markdown files

 **File Structure:**
 
-- Blog posts are in `src/routes/blog/[post-slug]/` directories
-- Each post has:
-  - `+page.svelte` - Main content (MDsveX)
-  - `+page.server.ts` - Server-side data loading
-  - `metadata.ts` - Post metadata export
-
-**Front Matter (YAML):**

+Blog posts live in `src/routes/blog/[post-slug]/`. Each post directory contains exactly three files:
+
+| File              | Purpose                                                        |
+| ----------------- | -------------------------------------------------------------- |
+| `metadata.ts`     | Typed post metadata (title, date, tags, etc.)                  |
+| `+page.server.ts` | Server-side data loader (identical boilerplate for every post) |
+| `+page.svelte`    | Post content written as a Svelte component                     |
+
+**`metadata.ts` format:**
+
+```typescript
+export const metadata = {
+  title: 'Post Title',
+  slug: 'post-slug', // must match the directory name
+  contributor: 'Author Name',
+  contributorSlug: 'author-slug', // matches a directory under src/routes/contributor/
+  date: '2024-01-15T12:00:00.000Z', // ISO 8601
+  coverImage: '/images/posts/post-slug/cover.webp',
+  excerpt: 'Brief description for listings and SEO.',
+  tags: ['Rust', 'BitTorrent'] // title-case tags
+};
 ```
 
-Optional fields:
+**`+page.server.ts` boilerplate** (copy verbatim for every post):
 
-- `updated`: "2024-01-20" - Last update date
-- `tags`: ["rust", "tracker"] - Additional tags
+```typescript
+import { getMetadata } from '$lib/data/metadata';
+import type { PageServerLoad } from './$types';
 
-**Workflow:**
+export const load: PageServerLoad = async ({ url }) => {
+  const slug = url.pathname.split('/').filter(Boolean).pop();
+  if (!slug) throw new Error('Slug could not be determined.');
 
-1. Use Front Matter VS Code extension for easier management
-2. Create post directory: `src/routes/blog/my-new-post/`
-3. Add front matter and content
-4. Place images in `static/images/posts/my-new-post/`
-5. Reference images: `/images/posts/my-new-post/image.png`
-6. Use `<Image />` component for automatic optimization
-7. Run `npm run dev` to preview
-8. Metadata is auto-generated during build
+  const metadata = await getMetadata();
+  const currentPost = metadata.find((post) => post.slug === slug);
 
-**Supported Content:**
+  if (!currentPost) throw new Error(`Post not found: ${slug}`);
 
-- Standard Markdown syntax
-- Svelte components inline
-- Code blocks with syntax highlighting
-- Images with automatic optimization
-- Links with automatic external link handling
+  return { currentPost, allPosts: metadata };
+};

+
+**`+page.svelte` structure:**
+
+```svelte
+<script lang="ts">
+  import BlogPreview from '$lib/components/molecules/BlogPreview.svelte';
+  import Toc from '$lib/components/atoms/Toc.svelte';
+  import Post from '$lib/components/organisms/Post.svelte';

+          <BlogPreview post_data={post} />
+        </a>

+  </div>
+</Post>
+
+<style lang="scss">
+  @use '$lib/scss/breakpoints.scss' as bp;
+  /* styles here */
+</style>
+```
+
+Look at an existing post (e.g. `src/routes/blog/vortex-rust-bittorrent-client-review/`) as a full reference implementation.
+
+**Heading IDs for the Table of Contents:**
+
+The `<Toc />` component auto-generates a table of contents from `<h2>` and `<h3>` elements inside the `id="toc-contents"` div. Every heading must have a matching `id` attribute:
+
+```svelte
+<h2 id="my-section">My Section</h2>
+```
+
+**Supported content components:**
+
+| Component     | Import                                       | Usage                                                                     |
+| ------------- | -------------------------------------------- | ------------------------------------------------------------------------- |
+| `<Callout>`   | `$lib/components/molecules/Callout.svelte`   | `<Callout type="info">...</Callout>` (types: `info`, `warning`, `danger`) |
+| `<CodeBlock>` | `$lib/components/molecules/CodeBlock.svelte` | Fenced code with syntax highlighting                                      |
+| `<Image>`     | `$lib/components/atoms/Image.svelte`         | Optimised images (preferred over `<img>`)                                 |
+
+**Images:**
+
+- Place images in `static/images/posts/my-new-post/`
+- Reference them as `/images/posts/my-new-post/image.png`
+- Use `<Image src="..." alt="..." />` for automatic WebP/AVIF optimisation
+- Cover image should be named `cover.webp` and placed in the same folder
+
+### ⚠️ Critical: regenerate metadata during development
+
+`static/blogMetadata.json` drives the blog listing page and search. It is generated automatically by `npm run build`, but during development you must run it manually after adding or modifying a post's `metadata.ts`:
+
+```bash
+npx tsx scripts/generateMetadata.ts
+```
+
+Without this step the new post will not appear at `/blog`.
