/install powershell-safe-chain
功能描述
Chain PowerShell commands safely without &&. Use try/catch, ErrorAction, and proper sequencing for reliable Windows execution.
安全使用建议
This skill is a set of PowerShell best-practice instructions and appears coherent and low-risk. Before using: review the SKILL.md examples and any commands you plan to run against your system (the verification commands search *.ps1 in the working directory), and avoid blindly executing scripts from untrusted sources. Note the skill has no homepage or known author — if you need higher assurance, prefer guidance from a vetted documentation source or a trusted PowerShell style guide.
功能分析
Type: OpenClaw Skill
Name: powershell-safe-chain
Version: 1.0.0
The skill bundle provides instructions and examples for writing safe PowerShell scripts, focusing on proper error handling and command chaining without using `&&`. The `SKILL.md` content is purely educational and prescriptive, offering best practices and verification criteria for PowerShell code. There are no commands intended for malicious execution, data exfiltration, persistence, or prompt injection against the agent. All examples and verification steps are benign and align with the stated purpose of promoting secure scripting.
能力评估
Purpose & Capability
Name/description (safe PowerShell chaining) align with the content: the SKILL.md contains patterns, examples, and checks that are relevant to writing and verifying PowerShell scripts. No unrelated binaries, credentials, or config paths are requested.
Instruction Scope
The runtime instructions are limited to coding patterns, try/catch, ErrorAction, splatting, and a few verification commands (Select-String against *.ps1). Those checks operate on PowerShell scripts (reasonable for this skill). The doc does not instruct reading unrelated system secrets or sending data externally.
Install Mechanism
No install spec and no code files — instruction-only. This minimizes disk writes and external downloads; low installation risk.
Credentials
No environment variables, credentials, or config paths are required. The doc merely advises how to reference env vars in PowerShell when appropriate (using $env:VAR) and to use SecureString for passwords — proportionate to the topic.
Persistence & Privilege
Skill is not marked always:true and does not request persistent presence or modify other skills/settings. It is user-invocable and may be invoked autonomously (platform default), which is expected for skills.
