Base64 Tool

Encode or decode strings to and from base64 format upon user request.

Security Scan

The skill is coherent with its description (simple base64 encode/decode) and contains no network, file-exfiltration, or secret-access behavior.

Purpose & Capability

The skill's name, description, SKILL.md, and code all align: they implement base64 encode/decode. Minor inconsistency: the package metadata declares no required binaries, but the included implementation is a Python script — executing it requires a Python runtime that is not declared.

Instruction Scope

SKILL.md simply says to activate when the user requests base64 encoding/decoding. The code only reads CLI args and performs base64 operations; it does not read arbitrary files, network endpoints, or other environment variables.

Install Mechanism

There is no install spec (instruction-only). A small Python file is included but nothing is downloaded or installed from external URLs, so install risk is minimal.

Credentials

The skill requests no environment variables, credentials, or config paths. The code does not access anything sensitive.

Persistence & Privilege

always is false and the skill does not request elevated or persistent privileges or modify other skills' configs.

Assessment

This skill appears safe and does exactly what it says: a small base64 encoder/decoder. Two practical notes before installing: (1) the package metadata does not list any required binaries but the implementation is a Python script — make sure the agent environment provides a Python runtime if you expect the code to run; (2) the script prints messages in Chinese but otherwise contains no networking or secret access. If you want to be extra cautious, open the included base64_tool.py (it's short) to verify behavior yourself before enabling execution in an automated agent.
