How does this skill differ from simply asking a chatbot to write a description?

Unlike generic AI prompts, this skill enforces technical rules like mandatory 0:00 start times, minimum chapter durations, and hashtag limits to ensure your metadata actually functions and ranks.

What inputs do I need to provide to generate a complete description?

The skill requires a video title, primary keywords, a content summary, and your intended timestamps; it then outputs a formatted .txt file ready to copy into the YouTube Studio.

Does the tool handle legal disclosures for affiliate links?

Yes, the skill includes a dedicated link management feature that automatically appends required affiliate and sponsor disclosures to your resource lists to keep your channel compliant.

What technical environment is required to run the YouTube Description Builder?

This is a Python-based CLI tool that works with standard .txt and .csv files, making it easy to integrate into local workflows or automated content pipelines.

What is included in the purchase of this skill?

You receive the core Python script, documentation for input formatting, and a set of templates to ensure consistent branding across all your video uploads.

Can this skill automatically generate timestamps by watching my video?

The tool validates existing timestamps for formatting and duration rules, but it does not have the ability to listen to or transcribe audio to create timestamps from scratch.

About this skill

Writing YouTube descriptions that actually rank requires more than just a summary. Most creators lose clicks because their first 150 characters lack keywords or their timestamps fail to trigger video chapters.

What it does

Search optimization crafts keyword-rich opening sentences designed for the search results page snippet.
Chapter validation ensures timestamps meet YouTube requirements, including the 0:00 start and minimum duration rules.
Link management organizes resources and social links while appending necessary affiliate and sponsor disclosures.
Compliance checking monitors hashtag density to avoid the 15-tag penalty that causes YouTube to ignore metadata.
Template generation builds consistent layouts for credits, related playlists, and music attributions.

How it works

Provide the video title, primary keyword, and a raw summary of the content.
Input a list of timestamps or use the check command to validate an existing draft.
Supply links and specify which ones require affiliate disclosures.
Review the generated .txt file containing the formatted description and validated hashtags.

Frameworks & tools

This tool uses a Python CLI script and standard text files (.txt, .csv) for input, making it compatible with any local development environment or automated content pipeline.

Why this beats prompting it yourself

Generic prompts often hallucinate timestamps or forget to include mandatory affiliate disclosures. This skill enforces YouTube's specific technical constraints for chapters and hashtag limits every time.

Use cases

Generating SEO-optimized descriptions for technical tutorials or product reviews.
Auditing existing video metadata for broken chapter rules or excessive hashtags.
Standardizing descriptions across a large channel to maintain brand consistency.

Known limitations

Requires manual input of timestamps or a pre-generated chapter file. It does not transcribe video audio directly.
