Security Scan

The skill is a local, instruction-only copy/rsync reference that ships a readable bash script; its requirements and behavior match the description and nothing in the package requests unexpected credentials, installs, or network access.

Purpose & Capability

The name/description (copy/rsync/CoW reference) match the included SKILL.md and the bundled scripts. No unrelated credentials, binaries, or config paths are requested.

Instruction Scope

SKILL.md tells the agent to run scripts/script.sh with a small set of documented subcommands. The bundled script's visible code prints guidance text and examples rather than executing remote or system-altering operations. The instructions do not request reading unrelated files or exfiltrating data.

Install Mechanism

No install spec is provided (instruction-only plus a local script). Nothing is downloaded or written to disk beyond the included script, so install risk is minimal.

Credentials

The skill declares no required environment variables or credentials. SKILL.md documents an optional COPY_DIR variable (a harmless config), which is proportionate to the skill's purpose.

Persistence & Privilege

The skill is not flagged always:true and uses default agent invocation settings. It does not request persistent system-wide changes or access to other skills' configs.

Assessment

This skill appears internally consistent and safe: it provides documentation via a bundled bash script and does not request credentials or external installs. Before enabling, quickly review the full scripts/script.sh to ensure there are no hidden commands beyond printed guidance (the provided portion only emits help text). If you allow the agent to invoke skills autonomously, remember that the skill contains shell examples (cp, rsync, dd, rm-like patterns in docs) — those are just examples, but avoid giving the agent untrusted inputs that could cause destructive file operations on your system. If you need stricter control, run the skill manually or in a sandboxed environment first.

Copy — File & Data Copy Operations Reference

Quick-reference skill for file copy strategies, rsync patterns, copy-on-write, and cross-platform synchronization.

When to Use

• Duplicating files or directory trees with specific filters
• Setting up rsync-based backups or mirrors
• Understanding copy-on-write (CoW) behavior
• Implementing efficient copy strategies for large datasets
• Troubleshooting copy failures and permission issues
