SKILL: Social Media Manager
Goal
Automate the creation and scheduling of high-engagement social media content across any platform (TikTok, Instagram, X/Twitter, LinkedIn, Facebook, YouTube, and more) using AI generation and the Postiz API.
Supported Platforms
Postiz supports multi-platform publishing. Any platform you connect in Postiz can be targeted:
- TikTok — Slideshows, carousels, short videos
- Instagram — Reels, carousels, single-image posts
- X / Twitter — Text posts, image threads
- LinkedIn — Articles, image posts, carousels
- Facebook — Posts, stories, reels
- YouTube — Shorts, community posts
- Pinterest, Reddit, Threads, and more as Postiz adds integrations
Workflow
- Research & Ideation: Brainstorm hooks using the "Conflict Formula":
[Person] + [Conflict/Doubt] -> [AI Solution] -> [Resolution]. - Content Generation: Use AI to generate platform-appropriate content.
- Images/Slides: AI-generated visuals (e.g., Nano Banana Pro, gpt-image-1.5) at platform-optimal resolutions.
- Text: AI-written captions, threads, or articles tailored to each platform's tone and format.
- Video thumbnails: AI-generated cover images for video content.
- Platform Adaptation: Adjust content format per platform:
- TikTok/Instagram: Portrait 1024x1536, 6-slide carousels
- X/Twitter: Landscape/square images, concise text
- LinkedIn: Professional tone, landscape images
- YouTube Shorts: Portrait video thumbnails
- Consistency Check: Ensure "locked architecture" (same subject/theme, different styles).
- Critical: Write one detailed description of the subject and reuse it in EVERY prompt. Only change the style/lighting/context.
- Scheduling & Publishing: Upload and schedule via Postiz API.
- Draft mode (
SELF_ONLY) for review before publishing. - Scheduled posts for optimal engagement times.
- Cross-post the same content across multiple platforms simultaneously.
- Notification: Ping user with the caption and links to review/publish.
Postiz API Integration
Postiz acts as the universal publishing layer. One API handles all connected platforms.
Configuration
- API URL:
https://api.postiz.com/public/v1 - Auth Header:
Authorization: (No Bearer prefix). - Media Upload:
POST /upload first to get id and path. - Posting Method: Use
UPLOAD (Draft) for multi-image content. DIRECT_POST works for single-image/text posts.
Posting Structure
- Top level:
type ("now" or "schedule"), date (ISO 8601), posts (array). - Post level:
integration: { id: "..." }, value: [ { content: "...", image: [ { id, path } ] } ]. - Settings level: Platform-specific settings (e.g.,
__type: "tiktok", __type: "instagram", etc.).
Technical Specs
- Upload Media:
curl -X POST {API_URL}/upload -H "Authorization: {KEY}" -F "file=@path/to/file" - Create Post:
curl -X POST {API_URL}/posts -H "Authorization: {KEY}" -H "Content-Type: application/json" -d '{...}' - List Integrations:
curl {API_URL}/integrations -H "Authorization: {KEY}" — use this to discover connected platforms and their integration IDs.
Prompt Strategy
The Conflict Formula
Adaptable to any product, service, or brand:
[Person] + [Common Pain Point] -> [Your Solution] -> [Success/Resolution]- Identify 4-6 pain points per product for content variety.
- Each pain point becomes a unique content series.
Slide/Carousel Structure
- Slide 1: The "Before" or "Conflict" state + Hook Text Overlay
- Slides 2-5: The "Transformation" or style options
- Slide 6: The "Final Result" / Call to Action
Success Log
- 2026-02-14: Posted "Rejected TWICE" carousel (6 slides, Conflict Formula). Fixed API fields:
duet/stitch/comment (booleans), autoAddMusic ("yes"/"no"), brand_content_toggle/brand_organic_toggle (booleans). Top-level shortLink (bool) and tags (array) required. - 2026-02-13: Successfully transitioned to
UPLOAD method for TikTok slideshows. Confirmed that DIRECT_POST triggers ERROR state for multi-image sequences.
Failure Log
- 2026-02-13: API Authentication requires
Authorization: (no Bearer). - 2026-02-13: Postiz requires
content_posting_method and privacy_level in settings. - 2026-02-13: Draft upload via Postiz requires valid media URLs (uploads.postiz.com) and correct
posts array structure.
