Cloud Uploader

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

Copy code
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:

yamlCopy code
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 ${CLAUDE_PLUGIN_ROOT}/reference/cloud/setup-guide.md for detailed setup instructions.

Required Files

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

Python Dependencies

bashCopy code
# If using the shared venv (recommended)
~/.bitwize-music/venv/bin/pip install -r ${CLAUDE_PLUGIN_ROOT}/requirements.txt

# Or install separately
pip install boto3

The upload script uses ~/.bitwize-music/venv if available, otherwise falls back to system Python.

Workflow

1. Verify Prerequisites

Check config:

bashCopy code
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:

bashCopy code
ls {audio_root}/artists/{artist}/albums/{genre}/{album}/promo_videos/
ls {audio_root}/artists/{artist}/albums/{genre}/{album}/album_sampler.mp4

If missing:

Copy code
Error: Promo videos not found.

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

2. Get Python Command

Call get_python_command() first to get the venv Python path and plugin root. Use these for all bash invocations below.

Copy code
PYTHON="{python from get_python_command}"
PLUGIN_DIR="{plugin_root from get_python_command}"

3. Preview Upload (Dry Run)

Preview first:

bashCopy code
$PYTHON "$PLUGIN_DIR/tools/cloud/upload_to_cloud.py" {album} --dry-run

Output shows:

• Provider and bucket
• Files to upload
• S3 keys (paths in bucket)
• File sizes

4. Upload Files

Upload all (promos + sampler):

bashCopy code
$PYTHON "$PLUGIN_DIR/tools/cloud/upload_to_cloud.py" {album}

Upload only track promos:

bashCopy code
$PYTHON "$PLUGIN_DIR/tools/cloud/upload_to_cloud.py" {album} --type promos

Upload only album sampler:

bashCopy code
$PYTHON "$PLUGIN_DIR/tools/cloud/upload_to_cloud.py" {album} --type sampler

Upload with public access:

bashCopy code
$PYTHON "$PLUGIN_DIR/tools/cloud/upload_to_cloud.py" {album} --public

5. 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

Copy code
## 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:

Copy code
{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:

Copy code
/bitwize-music:cloud-uploader my-album

Preview only:

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

Upload promos only:

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

Upload with public access:

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

Error Handling

"Cloud uploads not enabled"

• Add cloud.enabled: true to config
• See ${CLAUDE_PLUGIN_ROOT}/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}/artists/{artist}/albums/{genre}/{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)
