Social post

Social Posting Skill

Post to multiple social media platforms via a unified social posting API with automatic provider fallback.

---

Setup

Location: ~/social-posting-api/ (configurable — point to wherever you cloned your posting API)

Environment:

cd ~/social-posting-api
source venv/bin/activate

Required env vars in .env:

• POSTFORME_API_KEY - Primary provider (PostForMe)
• LATE_API_KEY - Fallback provider (LATE)

You only need one provider to get started. PostForMe is recommended as the primary.

Workflow for Posting

Step 1: Check Connected Accounts

Always check what's connected first:

cd ~/social-posting-api
source venv/bin/activate && python -c "
from social_posting import SocialPostingClient
from dotenv import load_dotenv
load_dotenv()
client = SocialPostingClient()
for acc in client.get_accounts():
    print(f'{acc.platform}: {acc.username}')
"

Step 2: Prepare Content

• Twitter: Keep under 280 chars
• LinkedIn: Can be longer, professional tone
• Instagram: Needs at least 1 image
• Xiaohongshu: Use xhs-image-gen skill for carousel content

Step 3: Execute Post

source venv/bin/activate && python -c "
from social_posting import SocialPostingClient
from dotenv import load_dotenv
load_dotenv()

client = SocialPostingClient()
result = client.post(
    content='''Your content here''',
    platforms=['platform1', 'platform2'],
    media_urls=['https://example.com/image.jpg']  # Optional
)
print(f'Success: {result.success}')
print(f'Provider: {result.provider}')
print(f'Post ID: {result.post_id}')
"

Error Handling

Error	Cause	Solution
"No connected accounts"	Platform not linked	Connect via provider dashboard
"Instagram requires media"	Text-only post	Add at least 1 image URL
"HTTP 401"	Invalid API key	Check .env file
"All providers failed"	Both providers down	Try again later

Cross-Posting Strategy

For open source announcements:

result = client.post(
    content="🚀 Just open-sourced my project!\n\nGitHub: https://github.com/yourusername/your-repo",
    platforms=["twitter", "linkedin"]
)

For visual content:

# Multi-image post
result = client.post(
    content="Behind the scenes 🔧",
    platforms=["instagram"],
    media_urls=[
        "https://example.com/image1.jpg",
        "https://example.com/image2.jpg",
    ]
)
