name: youtube-publish description: "End-to-end YouTube publishing workflow using ordered scripts: prepare/concat video, upload draft, transcribe with Parakeet, generate copy+thumbnails with Gemini, update YouTube metadata, then schedule socials (Postiz) 15 minutes after publish."

YouTube Publish (Scripted Flow)

Use scripts in order. Stop for validation after copy + thumbnail generation. Ask exact publish time if not provided.

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 all three 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 massive white text. Use max 3-4 words. Don't mention names explicitly. Us "subject" instead.
• Workflow: Upload a private draft before generating copy so the video URL can be used in newsletter/social text.
• Links: In social posts, the comment must not be just the link; it must include a brief descriptive text inviting to watch (e.g., "Watch the full technical analysis here: https://...").
• Timing: Schedule social posts 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.

Scripted flow (order)

1. Prepare video

   • Command:

     python scripts/prepare_video.py --videos /path/v1.mp4 [/path/v2.mp4 ...]
     

   • Output JSON with workdir, video, slug.

2. Upload draft (private)

   • Command:

     python scripts/upload_draft.py --video <video> --output-video-id <workdir>/video_id.txt --client-secret <path>
     

   • Write video_id.txt and create video_url.txt.

3. Transcribe + clean

   • Command:

     python scripts/transcribe_parakeet.py --video <video> --out-dir <workdir>
     

   • Outputs transcript.es.cleaned.srt.

4. Generate copy (Gemini headless)

   • Use gemini CLI on the cleaned SRT. Generate:
     • 3 Technical Authority Titles.
     • 3 Thumbnail ideas (Artifact-based).
     • Description (remove any self-link to current video).
     • Chapters (MM:SS).
     • LinkedIn post (per rules).
     • Save into <workdir>/content.md.

5. Generate 3 thumbnails (Gemini image)

   • Always include all three Antonio’s photo context. Create 3 images into <workdir>/thumb-1.png, thumb-2.png, thumb-3.png.
   • Example with multiple inputs:

     uv run /path/to/nano-banana-pro/scripts/generate_image.py --prompt "Antonio working..." --filename "thumb-1.png" --input-image assets/antonio-1.png assets/antonio-2.png assets/antonio-3.png
     

6. Stop to ask for validation of:

   • Title (choose one of the 3 generated).
   • Thumbnail (choose one of the 3 generated).
   • Description (edit if needed).
   • Chapters (edit if needed).
   • LinkedIn post (edit if needed).

7. Update YouTube

   • Command:

     python scripts/update_youtube.py --video-id <id> --title "..." --description-file <desc.txt> --thumbnail <thumb.png> --publish-at "YYYY-MM-DD HH:MM" --timezone <IANA> --client-secret <path>
     

8. Schedule socials (Postiz)

   • Command:

     python scripts/schedule_socials.py --text-file <linkedin.txt> --scheduled-date <ISO8601+offset> --comment-url <video_url> --image <thumb.png>
     

   • Use x-es by default for X.
   • Note: schedule_socials.py percent-encodes underscores in the --comment-url (e.g. _ -> %5F) to avoid LinkedIn/Postiz URL formatting issues.

9. Final Reminder

   • Explicitly remind the user to go to YouTube Studio to:
     • Enable monetization (not supported via API).
     • Add End Screens (not supported via API).
