Automated safety checks

scanned 1 Oct 2026

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.
Pinned to a commit: passed
Scanned kentoshimizu/sw-agent-skills at 5b7bafb626.
The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill provides guidance and enforces best practices for writing PowerShell scripts. It helps ensure consistency, readability, and maintainability of your PowerShell code by applying a defined style guide. The agent can analyze existing scripts or generate new ones adhering to the specified conventions.

When to use it

Code Review: Have the agent review an existing PowerShell script to identify stylistic issues and suggest improvements.
Script Generation: Generate new PowerShell scripts from scratch, ensuring they follow the defined style guide from the outset.
Team Standardization: Enforce a consistent coding style across a team of PowerShell developers.
Learning & Education: Use it as a learning tool to understand and apply PowerShell best practices.

Key capabilities

Style Guide Enforcement
Code Analysis
Script Generation
Consistency Checking

Example prompts

"Review this PowerShell script for style guide violations: [script content]"
"Generate a PowerShell script to list all files in a directory, following the established style guide."
"Analyze this script and suggest improvements based on the PowerShell style guide."

Tips & gotchas

The effectiveness of this skill depends on having a clearly defined and configured PowerShell style guide. Ensure that the agent has access to or is aware of the specific rules and conventions you want it to apply.
