Generate showcase from video

Overview

This skill automates the creation of high-quality Flutter case studies from video interviews or presentations. It fetches the transcript, analyzes the business and technical impact, and formats a blog post suitable for the official Flutter showcase.

Workflow

1. Extract transcript

Prompt the user for a YouTube URL if one hasn't been provided.

Execute the transcript extraction script:

dart run tool/get_video_transcript.dart "<youtube_url>"

2. Analyze & generate

Analyze the transcript to identify:
- Customer/Company name: Used for the final filename.
- Goal: The problem they were solving (this content should be part of the introductory paragraphs without a header).
- Why Flutter: Reasons for choosing Flutter.
- Their solution: Technical implementation details (mapped to the Their solution header).
- Key metrics: Quantifiable wins (Velocity, Reuse, FPS, Team size, etc. - mapped to the Results header).
CRITICAL: DO NOT use Markdown headers (e.g. # Header) in the content. Use Bold Text for the section titles as specified in references/blog-format.md.
Use the detailed structure and tone guidelines in references/blog-format.md.

3. Generate image assets

MANDATORY: Request an image (logo or app icon) from the user directly using the chat UI. The user can drag and drop or attach the image to the chat.
PROHIBITION: DO NOT use browser tools, search engines, or external websites to find the logo yourself. You must always wait for the user to provide the official asset.
Image naming: Image filenames (logo and card) MUST use underscores to separate words, even if the directory or slug uses hyphens (e.g., global_citizen_logo.png).
Once the image is attached, copy it to content/showcase/images/third_party/case_studies/<customer_name>/<customer_name_underscored>_logo.png.

Run the automatic padding script to generate a perfectly fitted 1450x1080 Showcase Card with a white background:

dart run tool/generate_showcase_card.dart "content/showcase/images/third_party/case_studies/<customer_name>/<customer_name_underscored>_logo.png" "content/showcase/images/third_party/case_studies/<customer_name>/<customer_name_underscored>_card.png"

4. Output Markdown & update YAML
