What it does

Cloud Uploader is an agent skill from bitwize-music-studio/claude-ai-music-skills. Uploads promo videos and content to Cloudflare R2 or AWS S3. Use when the user wants to host promo content for social media or distribution.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Video production. It works with Amazon S3, Cloudflare R2 and Python. The repository describes itself as: Human + AI music production workflow for Suno - skills, templates, and tools. The licence is CC0-1.0.

When your agent uses it

  • The user wants to host promo content for social media
  • Tasks that involve Video production

Example prompts

  • “Use the cloud-uploader skill to upload promo videos and content to Cloudflare R2 or AWS S3”
  • “/cloud-uploader”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Read, Bash, Glob

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  6. Report Results

What it can do on your machine

Read from SKILL.md and the folder at commit 58f32c2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pip
    • aws

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use pip and aws, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cloud Uploader loads about 2.1k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 625 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Bash, Glob

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:

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 ${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
bash
# 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:

bash
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:

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

If missing:

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.

PYTHON="{python from get_python_command}"
PLUGIN_DIR="{plugin_root from get_python_command}"
3. Preview Upload (Dry Run)

Preview first:

bash
$PYTHON "$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):

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

Upload only track promos:

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

Upload only album sampler:

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

Upload with public access:

bash
$PYTHON "$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
## 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:

LocationPath Structure
Local content{content_root}/artists/{artist}/albums/{genre}/{album}/
Local audio{audio_root}/artists/{artist}/albums/{genre}/{album}/
Cloud{artist}/{album}/ (no genre!)

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

OptionDescription
--type promosUpload only track promo videos
--type samplerUpload only album sampler
--type allUpload both (default)
--dry-runPreview without uploading
--publicSet files as public-read
--audio-root PATHOverride audio_root from config

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)
