Image Writer

Image Writer

This skill creates new "image" entries - visual content with brief captions that appear in the homepage feed alongside your thoughts, ideas, and articles.

File Locations

• Content files: src/content/images/
• Physical images: /public/images/

Order of Operations:

1. First, place the physical image file in /public/images/
2. Then, create the content entry in src/content/images/

If the user provides an image path that doesn't exist yet, ask them to place the image first or help them do so.

Filename Format

Use the format YYMMDD.md where:

• YY = 2-digit year (e.g., 25 for 2025)
• MM = 2-digit month (e.g., 01, 12)
• DD = 2-digit day (e.g., 05, 31)

Example: 260114.md for January 14, 2026

Image File Naming

For the physical image in /public/images/, use descriptive names like:

• YYMMDD_description.ext (e.g., 260114_dashboard.png)
• YYMMDD_screenshot.ext (e.g., 260114_terminal.png)
• YYMMDD_photo.ext (e.g., 260114_conference.jpg)

This keeps things organized and makes images easy to find.

Frontmatter Schema

---
date: YYYY-MM-DD              # required
imageUrl: /images/filename.ext  # required (path from /public/images/)
draft: false                   # optional, defaults to false
author: Nikola Balić           # optional, defaults to Nikola Balić
---

Field details:

• date: Required, YYYY-MM-DD format.
• imageUrl: Required, path to image in /public/images/. Must start with /images/.
• draft: Optional, defaults to false.
• author: Optional, defaults to "Nikola Balić".

Content Style Guidelines

Image captions should be brief and contextual:

• Length: 1-2 sentences typical (can be longer if needed)
• Purpose: Contextualize what the image shows
• Style: Conversational, can include links and emojis
• Content: Explain the "why" behind the image, not just "what" it is

Examples

Social media mention:

---
date: 2025-05-19
imageUrl: /images/250523_oreillyandkentbeck.jpeg

Apparently, @timoreilly considered it [noteworthy to highlight](https://www.oreilly.com/radar/takeaways-from-coding-with-ai/) that I agree with @KentBeck 🤷‍♂️ honored and humbled!

Dashboard visualization:

When to Use Images vs Other Content Types

How It Works

• Images appear on the homepage (/) in the main feed
• Integrated with search at /search
• Displayed with image and caption together
• Sorted chronologically (newest first)

Process

When the user wants to add an image:

1. Confirm the image file exists in /public/images/
2. Get the image filename for the imageUrl field
3. Determine today's date for the filename (YYMMDD.md) and frontmatter (YYYY-MM-DD)
4. Ask what context/caption they want to add
5. Draft the caption following the style guidelines
6. Create the file in src/content/images/
7. Confirm creation with the user

Important Reminders

• Always verify the physical image exists in /public/images/ first
• The imageUrl must start with /images/ (not /public/images/)
• Image files can be any format: .jpg, .png, .jpeg, .gif, .webp, etc.
• Keep captions brief - this isn't a blog article, just context for the visual
