Overview

This is a Markdown-only guide for creating and publishing skills, and its commands are disclosed examples aligned with that purpose.

Before installing, treat this as a guide that may lead an agent to suggest ClawHub publish, install, or update commands. Run broad update or publish commands only when you intend to change installed skills or publish content, and review generated skills for secrets before publishing.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

SkillSpector

Vulnerability Patterns

• Rogue Agent: Self-Modification, Session Persistence
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code

Self-Modification

• Category: Rogue Agent

Content

clawhub publish ./skills/my-skill/
clawhub publish ./skills/my-skill/ --dry-run  # Validate without publishing

# Update skills
clawhub update                          # Update all installed skills
clawhub update financial-analysis-agent  # Update specific skill
clawhub outdated                         # List skills with available updates

• Confidence: 85% confidence
• Finding: Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.
