YouTube Publish (Scripted Flow - AI Expert Edition)

Use scripts in order. No interactive pauses. The agent decides final values and passes them to scripts.

Behavior rules for the agent

• Tone & Authority: Strictly avoid clickbait terms ("Fácil", "Rápido", "Secreto"). Titles and copy must focus on engineering, architecture, and solving developer friction.
• Title Derivation: Do not ask for a title hint; derive it from the video stem and the technical density of the SRT.
• Scheduling: If the user provides a publish time, resolve to exact YYYY-MM-DD HH:MM using system time and pass --publish-at + --timezone. Always determine and pass --timezone.
• Thumbnail Generation: Generate 3 thumbnails by default using Antonio’s photo context (assets/antonio-1.png, antonio-2.png, antonio-3.png). Style: Dark mode, minimalist, cinematic lighting (cyan/purple), featuring a "Technical Artifact" (logo, code snippet, or nodes), or the person working in a dark office, server bunker, architect drafting table. Check what fits better to tell the story of the video. Bold white text. Use max 3-4 words.
• Workflow: Upload a private draft before generating copy so the video URL can be used in newsletter/social text.
• Links: In the newsletter, include a markdown link to the video with descriptive text. In social posts, say “Link en el primer comentario.”
• Timing: Schedule social posts + newsletter 15 minutes after the YouTube publish time.

Content Styles

LinkedIn Post Style

• Length/Format: 600–900 characters, 3–6 short paragraphs, 1–2 emojis.
• Strategy: 1 central idea focused on technical authority. No digressions.
• Closing: Final line “Link en el primer comentario.” followed by a short question or CTA.
• Restrictions: No hashtags.

Newsletter Style

• Tone: Long-form (220–320 words), conversational, same tone as DevExpert.
• Prefix: Campaign name and subject must be prefixed with: “🧑‍💻 [DEV]”.
• Greeting: Always start with: “¡Hola DevExpert!”.
• Structure:
• Greeting + context.
• 2–3 development paragraphs (Technical insight/problem solved).
• “En el vídeo verás:” + 2–4 bullets.
• Markdown link with descriptive text (e.g., [Ver la clase de arquitectura](https://...)).
• Closing + CTA to comment.
• Optional P.S.
• Sign-off: Must be “Un abrazo,” (blank line) “Antonio.”
• Variety: Vary the opening and pacing; avoid repetitive templates.

Don't include the title in the content of the newsletter.
