# 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:**
```bash
cd ~/social-posting-api
source venv/bin/activate
```

**Required env vars in `.env`:**
- `POSTFORME_API_KEY` - Primary provider ([PostForMe](https://postforme.dev))
- `LATE_API_KEY` - Fallback provider ([LATE](https://getlate.dev))

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

---

## Quick Commands

### Check Connected Accounts
```python
from social_posting import SocialPostingClient
from dotenv import load_dotenv
load_dotenv()

client = SocialPostingClient()
print("Providers:", client.available_providers)
for acc in client.get_accounts():
    print(f"  {acc.platform}: {acc.username}")
```

### Post Text Only
```python
result = client.post(
    content="Your post content here",
    platforms=["twitter", "linkedin"]
)
print(f"Success: {result.success}, Provider: {result.provider}")
```

### Post with Images
```python
result = client.post(
    content="Check out these photos!",
    platforms=["instagram"],
    media_urls=[
        "https://example.com/image1.jpg",
        "https://example.com/image2.jpg"
    ]
)
```

### Schedule a Post
```python
from datetime import datetime

result = client.post(
    content="Scheduled post",
    platforms=["linkedin"],
    scheduled_for=datetime(2025, 1, 15, 9, 0)  # UTC
)
```

## Complete Posting Script

```python
#!/usr/bin/env python
"""Post to social media platforms."""

import sys
sys.path.insert(0, '~/social-posting-api')  # Update this path

from social_posting import SocialPostingClient
from dotenv import load_dotenv
load_dotenv('~/social-posting-api/.env')  # Update this path

def post_to_social(content: str, platforms: list, media_urls: list = None):
    """Post content to specified platforms."""
    client = SocialPostingClient()

    # Check which platforms are connected
    accounts = client.get_accounts()
    connected = [a.platform for a in accounts]

    # Filter to only connected platforms
    valid_platforms = [p for p in platforms if p in connected]

    if not valid_platforms:
        print(f"No connected accounts for: {platforms}")
        print(f"Connected: {connected}")
        return None

    # Post
    result = client.post(
        content=content,
        platforms=valid_platforms,
        media_urls=media_urls
    )

    if result.success:
        print(f"✅ Posted via {result.provider}")
        print(f"   Post ID: {result.post_id}")
    else:
        print(f"❌ Failed: {result.error}")

    return result
```

## Workflow for Posting

### Step 1: Check Connected Accounts

Always check what's connected first:
```bash
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

```bash
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}')
"
```

## Connecting New Accounts

2. Click "Connect Account"
3. Select platform and authorize

### Via LATE (Fallback)

2. Connect social accounts
3. API key in `.env` will auto-detect new accounts

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

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