analyzing-security-headers
This skill analyzes HTTP security headers of a given domain to identify potential vulnerabilities and misconfigurations. It provides a detailed report with a grade, score, and recommendations for improvement. Use this skill when the user asks to "analyze security headers", "check HTTP security", "scan for security vulnerabilities", or requests a "security audit" of a website. It will automatically activate when security-related keywords are used in conjunction with domain names or URLs.
Best use case
analyzing-security-headers is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

## Overview This skill allows Claude to automatically analyze a website's HTTP security headers and provide a comprehensive report. It identifies missing or misconfigured headers and offers actionable recommendations to improve security posture. ## How It Works 1. **Receives URL**: Claude receives a URL or domain name from the user. 2. **Analyzes Headers**: The plugin fetches the HTTP headers from the specified URL and analyzes them against security best practices. 3. **Generates Report**: The plugin generates a detailed report, including a security grade, score, and specific recommendations for missing or misconfigured headers. ## When to Use This Skill This skill activates when you need to: - Analyze the security posture of a website. - Identify missing or misconfigured HTTP security headers. - Get recommendations for improving website security. - Audit a website for compliance with security best practices. ## Examples ### Example 1: Security Audit User request: "Analyze the security headers for example.com" The skill will: 1. Fetch the HTTP headers from example.com. 2. Analyze the headers for common security vulnerabilities. 3. Generate a report outlining the security grade, score, and any identified issues with recommendations. ### Example 2: Quick Security Check User request: "Check HTTP security for mywebsite.net" The skill will: 1. Fetch the HTTP headers from mywebsite.net. 2. Analyze the headers for common security vulnerabilities. 3. Generate a report outlining the security grade, score, and any identified issues with recommendations. ## Best Practices - **Prioritize HSTS**: Ensure HSTS is properly configured to prevent downgrade attacks. - **Implement CSP**: Start with a strict Content Security Policy to mitigate XSS vulnerabilities. - **Regularly Scan**: Schedule regular scans to identify new vulnerabilities and misconfigurations. ## Integration This skill can be used in conjunction with other security plugins to provide a more comprehensive security assessment. For example, it can be paired with a vulnerability scanner to identify both header-related and code-level vulnerabilities.

analyzing-system-throughput
This skill enables Claude to analyze and optimize system throughput. It is triggered when the user requests throughput analysis, performance improvements, or bottleneck identification. The skill uses the `throughput-analyzer` plugin to assess request throughput, data throughput, concurrency limits, queue processing, and resource saturation. Use this skill when the user mentions "analyze throughput", "optimize performance", "identify bottlenecks", or asks about system capacity. It helps determine limiting factors and evaluate scaling strategies.
checking-session-security
This skill enables Claude to check session security implementations within a codebase. It analyzes session management practices to identify potential vulnerabilities. Use this skill when a user requests to "check session security", "audit session handling", "review session implementation", or asks about "session security best practices" in their code. It helps identify issues like insecure session IDs, lack of proper session expiration, or insufficient protection against session fixation attacks. This skill leverages the session-security-checker plugin. Activates when you request "checking session security" functionality.
analyzing-text-sentiment
This skill enables Claude to analyze the sentiment of text data. It identifies the emotional tone expressed in text, classifying it as positive, negative, or neutral. Use this skill when a user requests sentiment analysis, opinion mining, or emotion detection on any text, such as customer reviews, social media posts, or survey responses. Trigger words include "sentiment analysis", "analyze sentiment", "opinion mining", "emotion detection", and "polarity".
performing-security-testing
This skill automates security vulnerability testing. It is triggered when the user requests security assessments, penetration tests, or vulnerability scans. The skill covers OWASP Top 10 vulnerabilities, SQL injection, XSS, CSRF, authentication issues, and authorization flaws. Use this skill when the user mentions "security test", "vulnerability scan", "OWASP", "SQL injection", "XSS", "CSRF", "authentication", or "authorization" in the context of application or API testing.
performing-security-audits
This skill allows Claude to conduct comprehensive security audits of code, infrastructure, and configurations. It leverages various tools within the security-pro-pack plugin, including vulnerability scanning, compliance checking, cryptography review, and infrastructure security analysis.
