# Description Builder
## Purpose
Build the video description: opening line, timestamped chapters, CTA stack, link architecture, hashtags. The description is a secondary-but-load-bearing surface — primary CTAs (lead magnet, pinned VSL, application) live here.
## Decision Logic
Description's job: chapter the video for skim consumption + house the CTA stack + reinforce title-promise. The CTA stack is ordered: (1) lead magnet, (2) pinned VSL, (3) application, (4) newsletter, (5) social.
Series videos have a series-cross-link in the first line.
Hashtags: 3-5 max, channel-specific not generic.
## Tacit Principles
1. **First line is the hook duplicate.** Repeats the bound-promise from the title in slightly different words.
2. **Timestamps drive skim retention.** Chapters help the algorithm understand structure.
3. **CTA stack is ordered.** Lead magnet first, application last.
4. **Hashtags are not SEO magic.** 3-5 specific tags > 30 generic tags.
5. **Link UTM tracking is required.** All links carry UTMs for attribution.
6. **Banned vocab applies.**
## Process
### Step 0 — Gate check
distribution ≥ 30, offer ≥ 40.
### Step 1 — Load context
Title, script, series state, offer CTAs, lead magnet.
### Step 2 — Opening line
Restate title's bound-promise.
### Step 3 — Timestamped chapters
Per script section breaks.
### Step 4 — CTA stack
Lead magnet → pinned VSL → application → newsletter → social.
### Step 5 — Hashtags
3-5 specific.
### Step 6 — Series cross-link if applicabl
