This skill provides the official guidelines, step-by-step workflow, and standard templates for adding new pages/posts to this blog. Follow these instructions precisely to ensure consistency, accessibility, and correct indexing.
2025/a-new-post/ for a post named "A new post".index.html): Initialize the post with the standard metadata, semantic tags, and JSON-LD schema. Ensure the index.html uses the same template/structure as the other existing pages on the blog.icon.svg, title.svg, title.png):
icon.svg square logo with a solid background (no transparency).title.svg social preview embedding the icon.svg content, with a solid background and descriptive typography.title.svg to an opaque title.png using the macOS sips utility.index.html): Register the new page at the top of the list in the root index.html using the new post's icon.svg image.atom.xml): Add a feed entry at the top, and update the feed's root <updated> timestamp to today's date/time.Every blog post must reside in its own folder under the directory of the current calendar year:
[root]
├── YYYY/
│ └── [post-slug]/
│ ├── index.html <-- Post content
│ ├── icon.svg <-- Square logo (responsive light/dark mode)
│ ├── title.svg <-- 1200x630 social preview mockup (SVG)
│ └── title.png <-- 1200x630 social preview mockup (PNG)
2025/a-new-post/ for a post named "A new post".index.html)Use the template below to create YYYY/[post-slug]/index.html. Replace all placeholder values (YYYY, post-slug, [Post Title], [Post Description], etc.) with today's date and actual post details:

<img> tags within the blog post must have a descriptive alt= attribute. Do not leave it blank.<time> tag within the page must use the YYYY-MM-DD format (e.g., YYYY-MM-DD for display, and YYYY-MM-DDT00:00:00Z in JSON-LD and the datetime attribute).icon.svg, title.svg, title.png)To maintain the premium look and feel of the blog, high-quality vector assets are required for each post.
icon.svg)The icon appears in the hexagonal list on the home page and as the tab icon.
icon.svg in the new post's folder. Make sure the SVG includes a solid background (e.g., using a <rect width="100%" height="100%" fill="..."> as the base layer) with no transparency so it is always compatible and readable on both black and white pages. Responsive light/dark styles can be achieved via media queries, but a solid background remains mandatory.Minimal icon.svg Boilerplate:
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512" width="512" height="512">
<style>
.bg { fill: #ffffff; }

.stroke-shape { stroke: #333333; stroke-width: 8; fill: none; }
@media (prefers-color-scheme: dark) {
.bg { fill: #121212; }
.text { fill: #eeeeee; }
.stroke-shape { stroke: #eeeeee; }
}

<!-- Solid background rect with no transparency -->

title.png)Social networks require a static raster image. Generate a PNG version of title.svg using the sips command on macOS:
sips -s format png title.svg --out title.png
Note: Because of the solid background in the SVG, this will result in an opaque PNG. Run this command inside the new post directory. Always verify that title.png was created successfully and is opaque.
<head> section of the new page must contain social media markup (e.g., Open Graph, Twitter cards) referencing the generated title.png image.After creating the post folder and generating assets, register it in the main listing and feed.
index.html RegistrationOpen the root index.html file, locate the <ol class="pages"> tag, and insert the new post's list item at the very top (directly after <ol class="pages">):
icon.svg image in the root index listing. <li>
<a href="YYYY/[post-slug]/">
<figure>
<img loading="lazy" src="YYYY/[post-slug]/icon.svg" alt="" title="[Post Title]">
<figcaption>
[Post Title]
</figcaption>
</figure>
</a>
</li>
atom.xml) RegistrationOpen the root atom.xml file:
<updated> tag of the atom feed (near line 16) to today's date/time:
<updated>YYYY-MM-DDT00:00:00Z</updated>
<entry> element at the very top of the entry list (directly under the feed <updated> tag):
<entry>
<title>[Post Title]</title>
<link href="https://labs.steren.fr/YYYY/[post-slug]/"/>
<updated>YYYY-MM-DDT00:00:00Z</updated>
<id>https://labs.steren.fr/YYYY/[post-slug]/</id>
<summary></summary>
</entry>
<content> tag for the new entry; use an empty <summary> tag instead (e.g., <summary /> or <summary></summary>).Before marking the task as completed, verify the following:
YYYY/[post-slug]/).icon.svg loads cleanly, has responsive dark/light styles, and has a solid background with no transparency.title.svg has an opaque background, contains a left-hand visual with right-hand text, and has zero text overlap.title.png was correctly compiled via sips, is non-transparent, and has standard dimensions of 1200x630.<head> metadata in the new post points to the absolute Twitter and Open Graph image URLs on https://labs.steren.fr/....alt= attribute.index.html features the new listing at the very top of <ol class="pages"> using icon.svg.atom.xml contains the new entry at the top, feed <updated> is bumped, and the entry's <summary> is empty.Once you have completed creating the article, generating assets, and updating root indexes, you must launch a local web server at the root of this repository so the human can preview and verify the changes:
python3 -m http.server 8080npx -y http-server -p 8080 or npx -y serve -l 8080
