# HuggingFace Spaces Deployment Checklist

Quick checklist for deploying Writing Studio to HuggingFace Spaces.

## Pre-Deployment

- [ ] HuggingFace account created
- [ ] Reviewed [HF Spaces documentation](https://huggingface.co/docs/hub/spaces)
- [ ] Decided on Space name
- [ ] Chosen visibility (Public or Private)

## Required Files

Ensure these files are ready to upload:

- [ ] `app.py` - HF Spaces entry point
- [ ] `requirements.txt` - Python dependencies
- [ ] `src/writing_studio/` - Complete source directory
  - [ ] `core/` - Core modules
  - [ ] `services/` - Service layer
  - [ ] `utils/` - Utilities

## Optional Files

Recommended for better UX:

- [ ] `README_HF_SPACES.md` - User documentation with YAML config (rename to README.md)
- [ ] `LICENSE` - License file

## Configuration

- [ ] Review default settings in `app.py`
- [ ] Choose model (default: distilgpt2)
- [ ] Set hardware tier (default: CPU Basic - Free)
- [ ] Configure environment variables (if needed)

### Recommended Settings for Free Tier

The README_HF_SPACES.md file includes optimized settings:

```yaml
---
sdk: gradio
sdk_version: 4.0.0
app_file: app.py
suggested_hardware: cpu-basic
suggested_storage: small
---
```

For environment variables (optional), add in Space Settings:
```
DEFAULT_MODEL=distilgpt2
ENABLE_CACHE=true
```

## Deployment Steps

### Method 1: Direct Upload

- [ ] Go to [huggingface.co/new-space](https://huggingface.co/new-space)
- [ ] Fill in Space details:
  - [ ] Space name
  - [ ] License: MIT
  - [ ] SDK: Gradio
  - [ ] Visibility: Public/Private
- [ ] Click "Create Space"
- [ ] Upload files:
  - [ ] `app.py`
  - [ ] `requirements.txt`
  - [ ] `src/` folder (entire directory)
  - [ ] `.space_config.yml`
  - [ ] README.md (from README_HF_SPACES.md)
- [ ] Wait for build to complete
- [ ] Test the Space

### Method 2: Git Clone

- [ ] Create Space on HuggingFace
- [ ] Clone repository:
  ```bash
  git clone https://huggingface.co/spaces/USERNAME/SPACE_NAME
  ```
- [ ] Copy files to repository
- [ ] Commit and push:
  ```bash
  git add .
  git commit -m "Initial deployment"
  git push
  ```
- [ ] Monitor build in Logs tab
- [ ] Test the Space

## Post-Deployment Testing

- [ ] Space builds successfully
- [ ] App loads without errors
- [ ] Model loads correctly
- [ ] Test with sample text:
  ```
  The quick brown fox jumps over the lazy dog. This is a sample
  text to test the writing analysis features.
  ```
- [ ] Check all prompt packs work:
  - [ ] General
  - [ ] Literature
  - [ ] Tech Comm
  - [ ] Academic
  - [ ] Creative
- [ ] Verify rubric scoring displays:
  - [ ] Clarity score
  - [ ] Conciseness score
  - [ ] Organization score
  - [ ] Evidence score
  - [ ] Grammar score
- [ ] Check diff highlighting works
- [ ] Test error handling (submit empty text)
- [ ] Verify caching (same input twice should be instant)

## Performance Testing

- [ ] First load time acceptable (~30-60s)
- [ ] Subsequent loads faster (~5-10s)
- [ ] No memory errors
- [ ] No timeouts
- [ ] Cache working (check logs)

## Documentation

- [ ] README.md clear and helpful
- [ ] Examples provided
- [ ] Usage instructions included
- [ ] Troubleshooting section added
- [ ] Links to GitHub repo included

## Settings & Configuration

- [ ] Hardware tier selected (if not free)
- [ ] Environment variables set (if customizing)
- [ ] Sleep mode settings configured (for paid tiers)
- [ ] Analytics enabled (optional)
- [ ] Custom domain configured (optional)

## Optional Enhancements

- [ ] Add authentication (if needed)
- [ ] Set up custom domain
- [ ] Add usage examples in README
- [ ] Create demo video/GIF
- [ ] Add to HuggingFace Papers
- [ ] Share on social media

## Monitoring

- [ ] Check Logs tab regularly
- [ ] Monitor usage statistics
- [ ] Set up alerts (for paid tiers)
- [ ] Review error logs
- [ ] Track performance metrics

## Maintenance

- [ ] Schedule regular updates
- [ ] Monitor for new model releases
- [ ] Update dependencies periodically
- [ ] Review and respond to user feedback
- [ ] Check for security updates

## Troubleshooting Checklist

If Space doesn't work:

- [ ] Check Logs tab for errors
- [ ] Verify all files uploaded correctly
- [ ] Confirm file structure:
  ```
  SPACE_NAME/
  ├── app.py
  ├── requirements.txt
  └── src/
      └── writing_studio/
          ├── core/
          ├── services/
          └── utils/
  ```
- [ ] Review requirements.txt syntax
- [ ] Try factory reboot (Settings)
- [ ] Check model name spelling
- [ ] Verify hardware tier sufficient

## Common Issues

### Build Fails
- [ ] Check requirements.txt syntax
- [ ] Ensure app.py exists
- [ ] Verify Python version compatibility
- [ ] Check for missing dependencies

### Out of Memory
- [ ] Switch to smaller model (distilgpt2)
- [ ] Reduce cache size
- [ ] Upgrade hardware tier
- [ ] Limit text length

### Slow Performance
- [ ] Use distilgpt2 instead of larger models
- [ ] Ensure caching enabled
- [ ] Upgrade hardware tier
- [ ] Reduce generation length

### Model Not Found
- [ ] Check model name spelling
- [ ] Verify model exists on HuggingFace
- [ ] Check internet connectivity
- [ ] Try default model
