Cloud Uploader Skill

Upload promo videos and other album content to cloud storage (Cloudflare R2 or AWS S3).

Purpose

After generating promo videos with /bitwize-music:promo-director, upload them to cloud storage for:
- Hosting on websites
- Sharing via direct links
- CDN distribution
- Backup and archival

When to Use

• After promo videos generated, user wants to upload to cloud
• User says "upload promos to R2" or "upload to S3"
• User says "upload promo videos for [album]"
• Manual invocation only (not automatic)

Position in Workflow

Generate → Master → Promo Videos → **[Cloud Upload]** → Release

Optional step after promo-director, before release-director.

Prerequisites

Cloud Configuration

Cloud credentials must be configured in ~/.bitwize-music/config.yaml:

cloud:
  enabled: true
  provider: "r2"  # or "s3"

  # For Cloudflare R2
  r2:
    account_id: "your-account-id"
    access_key_id: "your-access-key"
    secret_access_key: "your-secret-key"
    bucket: "promo-videos"

  # For AWS S3
  s3:
    region: "us-west-2"
    access_key_id: "your-access-key"
    secret_access_key: "your-secret-key"
    bucket: "promo-videos"

See /reference/cloud/setup-guide.md for detailed setup instructions.

Required Files

• Promo videos generated (run /bitwize-music:promo-director first)
• Located at: {audio_root}/{artist}/{album}/promo_videos/
• Album sampler at: {audio_root}/{artist}/{album}/album_sampler.mp4

Python Dependencies

python3 -m venv ~/.bitwize-music/cloud-env
source ~/.bitwize-music/cloud-env/bin/activate
pip install -r {plugin_root}/requirements-cloud.txt

Always use the venv — activate it before running the upload script.

Workflow

1. Verify Prerequisites

Check config:

cat ~/.bitwize-music/config.yaml | grep -A 20 "cloud:"

Verify:
- cloud.enabled: true
- Provider credentials configured (r2 or s3)
- Bucket name set

Check promo videos exist:

ls {audio_root}/{artist}/{album}/promo_videos/
ls {audio_root}/{artist}/{album}/album_sampler.mp4

If missing:

Error: Promo videos not found.

Generate with: /bitwize-music:promo-director {album}

2. Preview Upload (Dry Run)

Always activate the venv and preview first:

source ~/.bitwize-music/cloud-env/bin/activate
cd {plugin_root}
python3 tools/cloud/upload_to_cloud.py {album} --dry-run

Output shows:
- Provider and bucket
- Files to upload
- S3 keys (paths in bucket)
- File sizes

3. Upload Files

Upload all (promos + sampler):

cd {plugin_root}
python3 tools/cloud/upload_to_cloud.py {album}

Upload only track promos:

python3 tools/cloud/upload_to_cloud.py {album} --type promos

Upload only album sampler:

python3 tools/cloud/upload_to_cloud.py {album} --type sampler

Upload with public access:

python3 tools/cloud/upload_to_cloud.py {album} --public

4. Verify Upload

For R2:
- Check Cloudflare dashboard → R2 → Your bucket
- Files should appear under {artist}/{album}/

For S3:
- Check AWS Console → S3 → Your bucket
- Or use AWS CLI: aws s3 ls s3://{bucket}/{artist}/{album}/

5. Report Results

## Cloud Upload Complete

**Provider:** R2 (or S3)
**Bucket:** {bucket}
**Album:** {album}

**Uploaded Files:**
- {artist}/{album}/promos/01-track_promo.mp4
- {artist}/{album}/promos/02-track_promo.mp4
- ...
- {artist}/{album}/promos/album_sampler.mp4

**Total:** 11 files, 125.4 MB

**Next Steps:**
1. Verify files in cloud dashboard
2. If public: Test URLs work
3. Continue to release: /bitwize-music:release-director {album}

Upload Path Structure

IMPORTANT: Cloud paths are FLAT - no genre folder.

The cloud path structure is different from the local content structure:

Files are organized in the bucket as:

{bucket}/
└── {artist}/
    └── {album}/
        └── promos/
            ├── 01-track_promo.mp4
            ├── 02-track_promo.mp4
            ├── ...
            └── album_sampler.mp4

Example for album "my-album" by "bitwize" in rock genre:
- Local: ~/music/artists/bitwize/albums/rock/my-album/
- Cloud: bitwize/my-album/promos/ (NOT bitwize/albums/rock/my-album/)

Command Options

Invocation Examples

Basic upload:

/bitwize-music:cloud-uploader my-album

Preview only:

/bitwize-music:cloud-uploader my-album --dry-run

Upload promos only:

/bitwize-music:cloud-uploader my-album --type promos

Upload with public access:

/bitwize-music:cloud-uploader my-album --public

Error Handling

"Cloud uploads not enabled"
- Add cloud.enabled: true to config
- See /reference/cloud/setup-guide.md

"Credentials not configured"
- Add credentials to config file
- For R2: account_id, access_key_id, secret_access_key
- For S3: access_key_id, secret_access_key

"Album not found"
- Check album exists in {audio_root}/{artist}/{album}/
- Verify artist name in config matches

"No files found to upload"
- Generate promo videos first: /bitwize-music:promo-director {album}

"Access Denied"
- Check credentials are correct
- For R2: Verify API token has write permissions
- For S3: Verify IAM policy allows s3:PutObject

"Bucket not found"
- Create bucket first in cloud dashboard
- Verify bucket name in config

Security Notes

• Credentials stored in config file (ensure proper file permissions)
• Config file should be gitignored in user's content repo
• Default: Files uploaded as private (not public)
• Use --public flag only for files intended for public access
• Consider using environment variables for CI/CD (future enhancement)
