Security & Testing Agent Skills

Scale Game Architecture Testing

Exposes hidden architectural weaknesses and scalability bottlenecks by simulating system behavior at extreme scales.

Secret Scanner

Identifies and remediates exposed API keys, passwords, and sensitive credentials within your codebase using pattern matching and entropy analysis.

Security Agent

Conducts automated security audits to identify vulnerabilities like SQL injection, XSS, and insecure dependencies.

Hypothesis Property-Based Testing

Automates edge case discovery and invariant validation using property-based testing with the Hypothesis framework.

Code Readability Reviewer

Optimizes code clarity and minimizes cognitive load using Miller's Law and readable code principles.

Claude Hookify: Custom Guardrails

Enforce custom safety rules and coding standards in Claude Code using declarative hooks and automated triggers.

Smart Test Tier Selection

Optimizes development workflows by automatically recommending the appropriate test tier based on the scope and impact of code changes.

Python Testing with pytest

Simplifies Python test suite creation and maintenance using pytest, mocking, and comprehensive coverage analysis.

Advanced Pytest Testing

Implements sophisticated Python testing patterns including scoped fixtures, parallel execution, and async support for robust application suites.

Spec Validation & Repair

Ensures the structural integrity and consistency of Spec-Driven Development (SDD) JSON files through comprehensive validation and automated fixing.

Property-Based Testing

Automates test case generation and edge-case discovery using fast-check for TypeScript and Hypothesis for Python.

Code Review Checklist

Automates structured code reviews by evaluating security, performance, correctness, and maintainability against industry best practices.

Test Quality Analysis

Analyzes test suites to detect anti-patterns, improve coverage, and eliminate flaky tests for more reliable software delivery.

Claude Security Settings

Configures granular security permissions, shell operator protections, and project-level access controls for Claude Code.

Code Quality & Static Analysis

Validates code integrity by performing automated linting and type checking to ensure high-quality, production-ready implementations.

Binary Analysis & Reverse Engineering

Analyzes binary files and firmware to extract strings, identify file signatures, and explore raw data using industry-standard tools.

Async API Testing Suite

Automates comprehensive API testing using pytest and httpx to ensure robust backend service reliability through asynchronous request handling.

Code Quality Assurance

Ensures codebase integrity through automated type checking, linting, and formatting within the Claude Code environment.

Rust Code Coverage (cargo-llvm-cov)

Generates precise Rust code coverage reports using LLVM-based instrumentation and integrates with CI/CD pipelines.

Mutation Testing Expert

Validates test suite effectiveness by introducing deliberate code mutations to identify weak assertions and untested logic paths.

Playwright Testing

Automates end-to-end web testing across multiple browsers using the Playwright framework for reliable UI and API verification.

Debugging Methodology

Implements a systematic approach to diagnosing and resolving complex software bugs using advanced system tracing and memory analysis tools.

Security Fundamentals

Implements robust security measures and follows OWASP Top 10 guidelines to protect applications from common vulnerabilities and data breaches.

Python Dead Code Detection

Identifies and prunes unused Python functions, classes, and variables to maintain clean and efficient codebases.

Elixir Discipline

Enforces a mandatory pre-response checklist and quality gates for all Elixir and Phoenix development tasks to ensure best practices and code correctness.

LimaCharlie Test Sensor Deployment

Deploys a temporary LimaCharlie EDR agent to local Linux or macOS environments for rapid security testing and detection rule validation.

Testing Strategy Selection

Optimizes test suite composition by applying test pyramid principles and coordinating specialized testing agents for unit, integration, and end-to-end coverage.

Code Anti-patterns Analysis

Identifies and resolves complex code smells, anti-patterns, and security vulnerabilities across multiple programming languages using structural pattern matching.

Vitest Testing

Streamlines unit and integration testing for JavaScript and TypeScript projects using the high-performance Vitest runner.

AI Writing Detector

Analyzes text for AI authorship markers using linguistic patterns, structural red flags, and model-specific fingerprints.
