## Features

- **🔄 All-or-nothing posting** - Automatic rollback on failures across all platforms
- **✅ Pre-validation** - Fail fast with comprehensive error reporting before posting
- **🧵 Threading support** - Native threading on Twitter and Bluesky, numbered series on LinkedIn
- **🎯 Stateless operations** - No persistent state between calls, perfect for AI agents
- **📱 Media support** - Images, videos, documents with platform-specific validation
- **🛡️ Robust error handling** - Detailed exception hierarchy with actionable guidance
- **🔌 Unified interface** - Same `post()` and `post_thread()` methods across platforms

## Platform Support

| Platform | Single Posts | Threading | Media Support | Rate Limits |
|----------|--------------|-----------|---------------|-------------|
| **Twitter/X** | ✅ | ✅ Reply chains | Images, videos | 500 posts/month (free) |
| **Bluesky** | ✅ | ✅ AT Protocol | Images, videos | More permissive |
| **LinkedIn** | ✅ | ⚠️ Numbered series* | Images, documents | 2s delays |
| **Reddit** | ✅ | ❌ No threading | None (deprecated) | Standard API limits |

_*LinkedIn "threading" creates separate, unconnected posts with numbers - not true threads._

## Installation

```bash
# From PyPI (when published)
pip install hydra-poster

# Development installation
git clone https://github.com/heysamtexas/hydra-poster
cd hydra-poster
make install
```

## Quick Start

```python
from hydra_poster import TwitterService, BlueSkyService, LinkedInService

# Basic posting
twitter = TwitterService("your_bearer_token")
result = twitter.post("Hello Twitter!")
print(f"Posted: {result.url}")

# Threading (platform-specific behavior)
bluesky = BlueSkyService("handle.bsky.social", "password")
messages = ["First post", "Second post", "Third post"]
thread_result = bluesky.post_thread(messages)
print(f"Thread: {thread_result.thread_url}")

# LinkedIn post series (NOT threading)
linkedin = LinkedInService("access_token", "person_urn")
series_result = linkedin.post_series(messages)  # Creates 3 separate posts
```

## Simple Examples

### Text Posts

```python
# Twitter
twitter = TwitterService("bearer_token")
result = twitter.post("Hello world! 🌍")

# Bluesky  
bluesky = BlueSkyService("username.bsky.social", "password")
result = bluesky.post("Testing from Python 🐍")

# LinkedIn
linkedin = LinkedInService("access_token", "urn:li:person:12345")
result = linkedin.post("Professional update 💼")
```

### Posts with Media

```python
from hydra_poster import MediaItem

# Single image
media = [MediaItem("/path/to/image.jpg", "image", alt_text="A beautiful sunset")]
result = twitter.post("Check this out!", media=media)

# Multiple images
media = [
    MediaItem("/path/to/img1.jpg", "image", alt_text="First image"),
    MediaItem("/path/to/img2.jpg", "image", alt_text="Second image")
]
result = bluesky.post("Photo gallery!", media=media)

# LinkedIn document
doc = [MediaItem("/path/to/doc.pdf", "document", alt_text="Report")]
result = linkedin.post("Quarterly report attached", media=doc)
```

### Reddit Posts

```python
from hydra_poster import RedditService, PostConfig

reddit = RedditService("access_token", "MyApp/1.0")

# Text post
config = PostConfig(metadata={
    "subreddit": "Python",
    "title": "Amazing Python Library!"
})
result = reddit.post("Check out this library...", config=config)

# Link post
config = PostConfig(metadata={
    "subreddit": "programming", 
    "title": "GitHub Project",
    "url": "https://github.com/username/repo"
})
result = reddit.post("Built something cool!", config=config)
```

## Advanced Examples

### Threading with Error Handling

```python
from hydra_poster.exceptions import ThreadPostingError

messages = [
    "🧵 Thread about AI development (1/3)",
    "The technology is advancing rapidly... (2/3)", 
    "What are your thoughts? (3/3)"
]

try:
    # Twitter creates reply chain
    result = twitter.post_thread(messages, rollback_on_failure=True)
    print(f"Thread created: {result.thread_url}")
    print(f"Individual post URLs: {[r.url for r in result.post_results]}")
    
except ThreadPostingError as e:
    print(f"Failed after posting {e.posted_count} messages")
    print(f"Rollback attempted: {e.rollback_attempted}")
    print(f"Error: {e}")
```

### Media Validation and Error Recovery

```python
from hydra_poster.exceptions import MediaValidationError

try:
    # This will validate before posting
    large_media = [MediaItem("/path/to/huge_file.mp4", "video")]
    result = twitter.post("My video", media=large_media)
    
except MediaValidationError as e:
    print(f"Media validation failed: {e}")
    print("Fix suggestions:")
    for suggestion in e.suggestions:
        print(f"  - {suggestion}")
        
    # Retry with smaller file
    small_media = [MediaItem("/path/to/small_vid.mp4", "video")]
    result = twitter.post("My video (compressed)", media=small_media)
```

### Cross-Platform Posting

```python
services = {
    'twitter': TwitterService("bearer_token"),
    'bluesky': BlueSkyService("handle", "password"),
    'linkedin': LinkedInService("token", "urn")
}

message = "Exciting announcement! 🚀"
results = {}
failed_platforms = []

for platform, service in services.items():
    try:
        result = service.post(message)
        results[platform] = result.url
        print(f"✅ {platform}: {result.url}")
    except Exception as e:
        failed_platforms.append(platform)
        print(f"❌ {platform}: {e}")

# Handle partial failures
if failed_platforms:
    print(f"Failed platforms: {failed_platforms}")
    # Implement retry logic or notification
```

## For AI Coding Agents

### Installation Verification
```python
# Always verify installation first
try:
    from hydra_poster import TwitterService
    print("✅ Library installed correctly")
except ImportError as e:
    print(f"❌ Installation failed: {e}")
    exit(1)
```

### Pre-Post Checklist

1. **✅ Credentials Check**
   ```python
   import os
   
   # Verify environment variables exist
   bearer_token = os.getenv('TWITTER_BEARER_TOKEN')
   if not bearer_token:
       raise ValueError("TWITTER_BEARER_TOKEN not found")
   ```

2. **✅ Content Validation**
   ```python
   message = "Your content here"
   
   # Twitter: 280 characters max
   if len(message) > 280:
       raise ValueError(f"Twitter message too long: {len(message)} chars")
   
   # LinkedIn: 3000 characters max  
   if len(message) > 3000:
       raise ValueError(f"LinkedIn message too long: {len(message)} chars")
   ```

3. **✅ Media Validation**
   ```python
   from pathlib import Path
   
   if media_path:
       path = Path(media_path)
       if not path.exists():
           raise FileNotFoundError(f"Media file not found: {path}")
       
       # Check file size (5MB limit for most platforms)
       if path.stat().st_size > 5 * 1024 * 1024:
           raise ValueError("Media file too large (>5MB)")
   ```

4. **✅ Always Use Error Handling**
   ```python
   from hydra_poster.exceptions import SocialMediaError
   
   try:
       result = service.post(message)
       if not result.success:
           print(f"Post failed: {result.error}")
   except SocialMediaError as e:
       print(f"Platform error: {e}")
       # Handle specific error types
   ```

### DO NOT ❌

- **Create service instances in loops** - Reuse instances
- **Post without error handling** - Always wrap in try/except
- **Assume credential format** - Always validate first
- **Retry 429 errors immediately** - Implement exponential backoff
- **Mix up LinkedIn threading** - Use `post_series()` instead

### Recovery Procedures

| Error Type | Solution |
|------------|----------|
| `AuthenticationError` | Check API tokens/credentials |
| `RateLimitError` | Wait and retry with exponential backoff |
| `MediaValidationError` | Check file size/format/existence |
| `ThreadPostingError` | Check if partial posts need cleanup |
| `NetworkError` | Implement retry with timeout |

## Platform-Specific Details

### Twitter/X - Native Reply Chains
- **Connection**: Each post replies to the previous post
- **UI**: Native thread interface with expand/collapse
- **Rollback**: Deletes tweets in reverse order
- **Limits**: 500 posts/month (free tier), 280 chars/post
- **Media**: Images (5MB), videos (512MB), up to 4 per post

### Bluesky - AT Protocol Threading  
- **Connection**: Posts linked via URI and CID references
- **UI**: Native thread interface with proper root/parent structure
- **Rollback**: AT Protocol delete operations
- **Limits**: More permissive than Twitter
- **Media**: Images and videos, platform-specific limits

### LinkedIn - Numbered Post Series ⚠️
- **Connection**: NONE - Posts are completely independent
- **UI**: No thread interface - posts scattered in feed
- **Behavior**: Like posting manually with added numbers
- **Method**: Use `post_series()` not `post_thread()`
- **Limits**: 3000 chars/post, 2s delays between posts
- **Media**: Images, documents (PDFs, Word docs)

### Reddit - Text and Link Posts
- **Threading**: Not supported
- **Required**: Subreddit and title for all posts
- **Media**: No longer supported (deprecated)
- **Types**: Text posts or link posts (with URL)
