Simple File Backup

Create a timestamped backup copy of a file in the same directory. Use when the user wants to save a copy of a file before making changes.

Security Scan

The skill does what it says — a small, local file-backup helper using cp and date with no network, credentials, or surprising behavior.

Purpose & Capability

Name/description match the artifacts. The skill only requires cp and date, which are exactly what the described functionality needs. The included run.sh implements the stated behavior (timestamped copy).

Instruction Scope

SKILL.md shows a single cp command using date; run.sh implements the same steps and only reads the specified file path and optional backup directory. It does not reference other files, environment variables, or external endpoints.

Install Mechanism

No install spec; this is instruction/code-only and does not download or extract external artifacts. The included shell script is small, readable, and self-contained.

Credentials

No environment variables, credentials, or config paths are requested. The script only uses standard POSIX tools (cp, date) and only accesses the file path(s) supplied by the caller.

Persistence & Privilege

Skill does not request persistent presence (always: false) and does not modify other skills or system-wide settings. It only performs an on-demand local file copy.

Assessment

This skill is coherent and small. If you plan to run it, review run.sh (already short and readable) to confirm it meets your expectations. Note: the script copies files locally and will overwrite only when a timestamp collision occurs (unlikely); it does not send data anywhere. Consider whether you need preservation of ownership/permissions/extended attributes (cp options like -p or -a) or handling of symlinks — the current script uses plain cp. If you need different behavior, modify the script accordingly before use.

File Backup

Create a timestamped backup copy of any file with a single command.

Usage

cp <FILE_PATH> <FILE_PATH>.bak.$(date +%Y%m%d_%H%M%S)

Arguments:

#	Name	Description
1	FILE_PATH	Path to the file to back up

Example

cp /home/user/config.yaml /home/user/config.yaml.bak.$(date +%Y%m%d_%H%M%S)

Output:

(no output on success)

The backup file is created as: ORIGINAL_NAME.bak.YYYYMMDD_HHMMSS

Example: config.yaml → config.yaml.bak.20260328_143022

Success / Failure

• Success: No output, exit code 0. Backup file created in same directory.
• Failure: Error message from cp (exit code non-zero, e.g. file not found)

Verify Backup

To confirm the backup was created:

ls -la <FILE_PATH>.bak.*
