rclone

A command-line file transfer tool for moving and synchronising files between your computer and cloud storage services such as Amazon S3, Google Drive, Dropbox, and Cloudflare R2.

In plain words
What is it for?
Uploading images, videos, or documents; synchronising folders; and backing up files to cloud storage or S3-compatible services.
Why use it?
It removes the need to learn separate upload and backup procedures for each storage provider. It also helps check that the required tool and cloud connection are configured before transferring files.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade D, and why

rclone scanned grade D with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check_setup.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

rclone File Transfer Skill

Setup Check (Always Run First)

Before any rclone operation, verify installation and configuration:

# Check if rclone is installed
command -v rclone >/dev/null 2>&1 && echo "rclone installed: $(rclone version | head -1)" || echo "NOT INSTALLED"

# List configured remotes
rclone listremotes 2>/dev/null || echo "NO REMOTES CONFIGURED"

If rclone is NOT installed

Guide the user to install:

# macOS
brew install rclone

# Linux (script install)
curl https://rclone.org/install.sh | sudo bash

# Or via package manager
sudo apt install rclone  # Debian/Ubuntu
sudo dnf install rclone  # Fedora

If NO remotes are configured

Walk the user through interactive configuration:

rclone config

Common provider setup quick reference:

Provider Type Key Settings
AWS S3 s3 access_key_id, secret_access_key, region
Cloudflare R2 s3 access_key_id, secret_access_key, endpoint (account_id.r2.cloudflarestorage.com)
Backblaze B2 b2 account (keyID), key (applicationKey)
DigitalOcean Spaces s3 access_key_id, secret_access_key, endpoint (region.digitaloceanspaces.com)
Google Drive drive OAuth flow (opens browser)
Dropbox dropbox OAuth flow (opens browser)

Example: Configure Cloudflare R2

rclone config create r2 s3 \
  provider=Cloudflare \
  access_key_id=YOUR_ACCESS_KEY \
  secret_access_key=YOUR_SECRET_KEY \
  endpoint=ACCOUNT_ID.r2.cloudflarestorage.com \
  acl=private

Example: Configure AWS S3

rclone config create aws s3 \
  provider=AWS \
  access_key_id=YOUR_ACCESS_KEY \
  secret_access_key=YOUR_SECRET_KEY \
  region=us-east-1

Common Operations

Upload single file

rclone copy /path/to/file.mp4 remote:bucket/path/ --progress

Upload directory

rclone copy /path/to/folder remote:bucket/folder/ --progress

Sync directory (mirror, deletes removed files)

rclone sync /local/path remote:bucket/path/ --progress

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

rclone is a skill published in the GitHub repository aegntic/compound-engineering (2 stars, last pushed 2mo ago), licensed MIT. It adds 94 tokens to every session and 1,090 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). It is 95% identical to rclone, differing in 12 lines, and is treated as a copy.
