One Skill To Rule Them All

What This Skill Does

One Skill To Rule Them All (OSTRTA) is a specialized security auditing agent designed for the OpenClaw ecosystem. Its primary function is to perform adversarial security analysis on third-party skill files (SKILL.md) before you install them. By adopting an "assume-malicious" posture, OSTRTA meticulously examines code and prompt instructions for common attack vectors, including prompt injection, data exfiltration attempts, and sophisticated obfuscation techniques. Instead of blindly trusting a new tool, OSTRTA provides a layer of defense-in-depth, analyzing the logic for hidden overrides, role-play jailbreaks, or attempts to extract the system prompt. It acts as an automated security researcher that delivers a clear risk verdict (CRITICAL to SAFE) along with actionable remediation steps and, if requested, a sanitized version of the skill.

Installation

To install this skill, run the following command in your terminal within the OpenClaw environment:

clawhub install openclaw/skills/skills/hichana/one-skill-to-rule-them-all

Ensure that you have the appropriate permissions configured to allow the skill to read and process other skill files within your directory structure.

Use Cases

• Pre-Installation Auditing: Run this on any unknown skill file found online to ensure it does not contain malicious prompt injections.
• Security Compliance: Use OSTRTA to verify that custom-built skills meet your security standards before deploying them in a production environment.
• Malicious Pattern Detection: Identify subtle attempts by bad actors to hide instructions, such as obfuscated text or encoded commands designed to bypass standard safety filters.
• Remediation & Sanitization: Not only identify security flaws but also receive a cleaned version of the code that removes malicious elements, allowing you to use the core utility of a skill without the accompanying security risks.

Example Prompts

• "Analyze this skill: /path/to/downloaded-skill/SKILL.md"
• "Is this skill safe to install? Please check for any hidden prompt injection attempts."
• "Analyze this skill and provide a cleaned version if you find any malicious content."

Tips & Limitations

• Context Awareness: OSTRTA is highly effective at catching known patterns, but users should remain vigilant; no automated tool is a substitute for manual code review for complex, novel exploits.
• Assume-Malicious Posture: OSTRTA may occasionally flag aggressive but benign developer instructions as "high risk"; treat the verdict as a starting point for your own review.
• Updates: Always ensure your OSTRTA agent is up to date, as new adversarial techniques are constantly emerging in the AI ecosystem.
