Description
cross-platform rar and winrar command-line archive handling for windows and linux. use when chatgpt needs to compress or extract archives with rar or winrar,...
Usage Guidance
This skill appears coherent for rar/winrar command-line help. Before installing or invoking it: (1) verify the download URLs are acceptable (they point to win-rar.com in the instructions); (2) avoid supplying passwords on the command line when possible because -p exposes secrets to process listings and logs — prefer interactive supply or other secure mechanisms; (3) persistent PATH edits and running installers will change system state and may require admin rights — only allow those actions if you trust the source and intend the change; (4) if you do not want an agent to autonomously download or install software, disable autonomous invocation or confirm actions before proceeding; (5) if uncertain, run commands in an isolated VM or container first.
Capability Analysis
Type: OpenClaw Skill
Name: rar-archive-helper
Version: 1.0.1
The skill provides instructions for an AI agent to manage RAR archives, but it includes high-risk behaviors such as persistently modifying the system PATH environment variable using 'setx' and downloading/executing installers from external URLs (win-rar.com). These instructions, found in SKILL.md and references/winrar-quick-reference.md, are plausibly intended for the stated purpose but represent significant security risks and potential system instability (e.g., PATH truncation via setx) if executed by an automated agent.
Capability Assessment
Purpose & Capability
Name and description match the runtime instructions: detect rar/winrar, repair PATH, run extraction/compression commands, handle multipart and passworded archives, and fall back to official downloads. The declared requirements (none) are proportionate to an instruction-only helper.
Instruction Scope
Instructions stay focused on archive handling and related troubleshooting. Two things to be aware of: (1) examples show passing passwords on the command line (rar -p...), which can expose secrets in process lists, logs, or transcripts; (2) the skill suggests persistent PATH edits and downloading official installers — both are reasonable for this purpose but can change system state and may require elevated privileges. The SKILL.md does not instruct reading unrelated files or exfiltrating data.
Install Mechanism
This is instruction-only (no install spec, no code files). The only external endpoints mentioned are official-looking WinRAR download URLs on win-rar.com rather than unknown shorteners or personal servers, which is proportionate for the stated fallback behavior.
Credentials
No environment variables or credentials are requested by the skill metadata. Password handling is user-provided and shown in examples, but the skill does not demand or store secrets itself.
Persistence & Privilege
always:false and normal autonomous invocation. The skill recommends persistent PATH changes (setx) and possibly running installers, which can alter system state and require admin privileges — this is coherent with its goal but is a system-impacting action users should permit explicitly.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install rar-archive-helper - After installation, invoke the skill by name or use
/rar-archive-helper - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.1
## rar-command-helper 1.0.1 Changelog
- Renamed the skill from "rar-archive-helper" to "rar-command-helper".
- Expanded and clarified descriptions to emphasize cross-platform (Windows and Linux) command-line support.
- Updated execution flow: detection, PATH repair, command execution, and single evidence-based retry if failure cause is clear.
- Standardized reporting with a clear `[Goal] → [Detect] → [Fix PATH] → [Run] → [Verify] → [Result]` template.
- Improved platform detection logic and reinforced the use of official download links as a fallback.
- Refined troubleshooting and retry rules, including encoding and multipart archive handling.
- Focused instructions on operational reliability and minimized nonessential prose.
v1.0.0
Initial skill release for rar-archive-helper.
- Guides users to use `rar` or `winrar` from the command line on Windows or Linux for extracting, creating, and troubleshooting archives.
- Detects OS, finds the appropriate executable, and repairs the path if needed before proceeding.
- Provides shell commands for extraction (with or without paths), archive creation, split volumes, and password protection.
- Handles multipart extraction, special character paths, encoding issues, and common errors.
- Always checks environment and verifies steps with minimal, executor-friendly output per a standard template.
- Supplies official download links if the rar utility is missing.
