+description: Create a new blog post in the feed
+---
+
+Create a new blog post with the following specifications:
+
+**Title**: $REMAINING_ARGS (all arguments)
+
+If no title is provided, prompt the user for a title interactively.
+
+**Steps to create the blog post:**
+
+1. Get the current date and time with `-07:00` timezone offset by running:
+
+   ```bash
+   TZ=America/Phoenix date +"%Y-%m-%d %H:%M:%S -07:00"
+   ```
+
+2. If no title was provided, ask the user: "What is the title for this blog post?"
+
+3. Generate a slugified directory name from the title:
+
+   - Convert to lowercase
+   - Replace spaces with hyphens
+   - Remove special characters (keep only alphanumeric and hyphens)
+   - Example: "My Great Post!" → "my-great-post"
+
+4. Create the directory at: `www/feed/<slugified-title>/`
+
+5. Create the file at: `www/feed/<slugified-title>/index.md`
+
+6. Populate the file with this frontmatter structure:
+
+   ```yaml
+   ---
+   tags:
+     - article
+   layout: article
+   author: eric
+   title: <user-provided title>
+   date: <datetime from step 1>
+   teaser: >-
+     <prompt user: "What is the teaser for this blog post?">
+   ---
+   ```
+
+7. After the frontmatter, add a blank line and a comment:
+
+   ```markdown
+   <!-- Write your blog post content here -->
+   ```
+
+8. Open the newly created file in the editor for the user to start writing.
+
+**Important notes:**
+
+- Each blog post gets its own directory under `www/feed/`
+- The main content file is always named `index.md`
+- The date MUST include the full timestamp with time, not just the date
+- Always use the `-07:00` timezone offset
+- The default layout is `article` but can be changed later if needed (e.g., `video`)
+- Additional frontmatter fields can be added later (e.g., `subhead`, `image`)
