Media Insertion for Changelogs

This skill teaches you how to properly insert media (images and videos) from Slack into changelog content.

Overview

When Slack messages include media files, the fetch_messages_from_channel tool downloads them to:

./docs/updates/media/YYYY-MM-DD/filename

You must insert references to these files in the markdown content so they appear in the final changelog.

Step 1: Identify Media from Slack Response

The Slack tool response includes processed_files for each message with media:

📝 Message 1:
   💬 Text: Check out this new feature!
   📎 Files (1):
      🖼️ Image: feature-screenshot_abc123.png
        Path: ./docs/updates/media/2025-11-06/feature-screenshot_abc123.png

Step 2: Insert Media References in Markdown

When writing the changelog content, insert the image reference right after describing the feature:

### New feature name

Description of the feature and what it does.

![Alt text describing the image](./media/2025-11-06/feature-screenshot_abc123.png)

More details about the feature...

Important:

• Use the local path format: ./media/YYYY-MM-DD/filename
• Write descriptive alt text that explains what the image shows (be specific, not generic)
• Place images where they make sense contextually (after introducing the feature)
• Only reference images that actually exist in the Slack response - check the file paths shown
• For videos (.mp4, .mov, .webm), use the same markdown syntax

Step 3: Verify Images Before Inserting

Before adding an image reference to your markdown:

1. Check the Slack tool response for the exact filename
2. Verify the path matches: ./docs/updates/media/YYYY-MM-DD/filename
3. Use that exact filename in your markdown reference: ./media/YYYY-MM-DD/filename

DO NOT insert image references for files that weren't downloaded or don't appear in the Slack response.

Step 4: Template Formatter Converts to Final Format

The template_formatter agent will later:

1. Verify each image file exists at ./docs/updates/media/YYYY-MM-DD/filename
2. Convert paths: ./media/YYYY-MM-DD/filename → /images/changelog/YYYY-MM-DD/filename
3. Wrap in Frame tags: <Frame><img src="/images/changelog/..." alt="..." /></Frame>
4. Convert video references to: <Frame><video src="/images/changelog/..." controls /></Frame>

Examples

Example 1: Single Image with Feature

Slack message:

• Text: "New planning mode UI with task list"
• Image: planning-mode_xyz789.png

Changelog content you write:

### Agent planning mode improvements

Agent now shows a clear task list in planning mode, making it easier to review and approve what will be built.

![Plan mode interface showing task list and Start building button](./media/2025-11-06/planning-mode_xyz789.png)

This improvement addresses feedback from users who wanted more visibility...

Example 2: Multiple Images for One Feature

Slack message:

• Text: "Redesigned settings page"
• Images: settings-before_abc123.png, settings-after_def456.png

Changelog content you write:

### Settings page redesign

We've redesigned the settings page with a cleaner layout and better organization.

![Previous settings page layout](./media/2025-11-06/settings-before_abc123.png)

The new design groups related settings together and uses clearer labels:

Example 3: Video Demo

Slack message:

• Text: "Agent can now stream responses"
• Video: streaming-demo_ghi789.mp4

Changelog content you write:

### Real-time Agent streaming

Agent responses now stream in real-time, showing you progress as it works.

This makes the experience feel faster and more interactive.

Best Practices

1. Always include media when available - If Slack downloaded a file, it's relevant to the update
2. Write descriptive alt text - Explain what the image shows, not just "screenshot"
3. Place strategically - Insert images after you introduce the concept they illustrate
4. Use local paths - Don't try to convert paths yourself, use ./media/YYYY-MM-DD/filename
5. One image per feature minimum - Visual updates should have visual proof

Common Mistakes to Avoid

❌ Don't skip images:

### New dashboard
We redesigned the dashboard.

✅ Do include them:

### New dashboard
We redesigned the dashboard with a modern layout.

❌ Don't use placeholder text:

✅ Do write descriptive alt text:
