Skill Security Analyzer
A specialized tool designed to evaluate Claude skills for security vulnerabilities, risks, and safety concerns before deployment through comprehensive security assessment and risk categorization.
This skill is essential for skill developers and library maintainers who need to ensure their skills are secure before deployment and want to identify potential security risks.
Core Purpose
The Skill Security Analyzer performs comprehensive security assessments to:
- Scan for vulnerabilities across all skill components
- Categorize risks with severity ratings
- Evaluate safety before deployment
- Conduct security audits with evidence-based findings
Security Assessment Functions
Vulnerability Scanning
Comprehensive examination of skill components:
- Metadata review and validation
- Instruction analysis for security patterns
- Script inspection for risky operations
- Asset evaluation for potential threats
Risk Categorization
Severity ratings across multiple levels:
- CRITICAL - Immediate security threats requiring urgent action
- HIGH - Significant risks that should be addressed promptly
- MEDIUM - Moderate concerns that need attention
- LOW - Minor issues for consideration
- POSITIVE - Security best practices identified
Pre-Deployment Safety
Evaluation protocols before skill release:
- Safety concern identification
- Third-party skill assessment
- Pattern matching against security anti-patterns
- Context-aware risk evaluation
Systematic Analysis Workflow
Three-Step Process:
- Extract - Gather skill contents and components
- Review - Analyze metadata, instructions, and scripts
- Cross-reference - Match patterns against security guidelines
Analysis Scope
The tool examines multiple dimensions of security:
- Data Exfiltration Risks - Unauthorized data transmission
- Network Access Patterns - External connection analysis
- Prompt Injection Vulnerabilities - Input validation checks
- File System Operations - Read/write permission review
- Command Execution - Shell and system command inspection
- Credential Handling - Secret and token management
- Third-Party Dependencies - External library risks
- Privilege Escalation - Permission boundary checks
- Resource Consumption - DoS and abuse potential
- Privacy Concerns - Data handling practices
Evidence-Based Findings
Analysis Principles:
- Cite specific code locations and references
- Distinguish legitimate functionality from security overreach
- Maintain context-aware evaluation
- Provide actionable remediation guidance
- Avoid assumptions without evidence
Structured Output Format
Security analysis results include:
- Executive Summary - High-level risk assessment
- Detailed Findings - Specific vulnerabilities with evidence
- Security Checklists - Compliance verification
- Severity Ratings - Categorized risk levels
- Remediation Guidance - Specific fix recommendations
- Code References - Exact locations of concerns
Activation Triggers
The analyzer activates when you request:
- Security analysis of skills
- Vulnerability assessments
- Security audits
- Safety evaluations
- Risk identification
- Pre-deployment security checks
Common trigger phrases:
- "analyze security"
- "security risks"
- "security audit"
- "is this skill safe"
