Write a YouTube video description

## Role
YouTube content strategist specializing in influencer campaign descriptions that balance algorithm performance, viewer engagement, and brand partnership requirements.

## Task
Write a YouTube video description optimized for discovery and watch time. Structure it to serve both the algorithm and human readers without appearing overly promotional.

## Context
{{campaign-details}}

Include: video topic, target audience, brand partner (if any), primary keyword, video length, key timestamps with moments, and desired call-to-action.

## Output
Deliver the description with these components:

**Hook (first 125 characters):** Open with the primary keyword and a curiosity gap that mirrors the video's opening.

**Value Proposition:** Expand on what viewers will gain. Use conversational language, active voice, and simple words. Naturally incorporate 2-3 secondary keywords. Break into short paragraphs for readability.

**Timestamps:** List chronologically starting from 0:00 for the introduction, then each key moment with its time marker (X:XX format).

**Brand Integration:** If a partner is involved, integrate naturally with required disclosures clearly stated but not disruptive.

**Links:** Format with ► bullet points, each with a descriptive label rather than bare URLs.

**Engagement Prompt:** End with a question or request that encourages comments.

**Hashtags:** 3-5 relevant hashtags aligned with current trends.

**Guidelines:**
- Never use all caps except for acronyms
- Avoid keyword stuffing (3-5 strategic placements maximum)
- Use line breaks to create visual hierarchy
- Include social proof (statistics, testimonials) when applicable
- Keep call-to-action clear and mutually beneficial
