Security & Testing Habilidades de Claude

Defense-in-Depth Validation

Implements multi-layered data validation across system boundaries to make software bugs structurally impossible.

Root Cause Tracing

Systematically traces bugs backward through the call stack to identify and resolve original triggers rather than just treating symptoms.

Defense-in-Depth Validation

Implements multi-layered data validation patterns across system boundaries to eliminate structural bugs and ensure system reliability.

Testing Anti-Pattern Prevention

Enforces best practices in software testing by preventing mock reliance, production code pollution, and incomplete test doubles.

Systematic Debugging

Implements a rigorous four-phase framework to identify root causes and ensure stable bug fixes before implementation.

Condition-Based Waiting

Eliminates flaky tests by replacing arbitrary delays with intelligent condition polling and state verification.

Verification Before Completion

Enforces a strict evidence-based workflow by requiring verified command output before any task is marked as complete.

Skill Testing with Subagents

Applies a rigorous TDD cycle to verify and harden Claude Code skills against pressure and rationalization.

Test-Driven Development (TDD) Workflow

Enforces a strict Red-Green-Refactor cycle to ensure code reliability and high test coverage.

Collect Selector

Identifies or generates the optimal data-testid selector for Playwright end-to-end testing based on a strict priority hierarchy.

Root Cause Tracing

Systematically traces bugs backward through the call stack to identify and fix the original source of errors rather than just symptoms.

Systematic Debugging Framework

Enforces a rigorous four-phase protocol to identify root causes and implement durable solutions for any technical bug or failure.

Testing Anti-Patterns Guard

Prevents fragile tests and production code pollution by enforcing strict best practices for mocking and Test-Driven Development.

Condition-Based Waiting

Eliminates flaky tests and race conditions by replacing arbitrary timeouts with smart condition polling.

Skill TDD & Stress Testing

Validates and bulletproofs Claude Code skills by applying a Red-Green-Refactor cycle to process documentation using high-pressure subagent scenarios.

Verification Before Completion

Mandates the execution of verification commands and evidence gathering before any task is marked as complete.

Strict Test-Driven Development (TDD)

Enforces a disciplined Red-Green-Refactor workflow to ensure high-quality, bug-free code through test-first implementation.

Test Plan Documentation

Generates structured E2E test plans with standardized templates and data-testid selectors for web application testing.

Testing & QA Strategy

Implements robust testing patterns and hypothesis-driven development strategies for high-quality software delivery.

Quality Guardian

Enforces production-grade code quality standards, test coverage requirements, and UI design constraints during the development process.

Code Quality & Testing Accelerator

Enforces high-standard code quality through automated testing strategies, comprehensive quality gates, and systematic review practices.

Root Cause Tracing

Systematically traces bugs backward through call stacks to identify and fix the original source of invalid data.

Systematic Debugging

Enforces a rigorous, four-phase investigation framework to identify root causes and eliminate fragile patches before any code fixes are applied.

Implementation Verifier

Verifies that code implementations strictly adhere to PRD requirements without unauthorized substitutions or omissions.

Claude Skill Reviewer

Reviews and validates Claude skills against Anthropic's official design philosophy and best practices.

ShellCheck Configuration Mastery

Optimizes shell script quality through advanced ShellCheck static analysis configuration and CI/CD integration patterns.

Vitest Migration & Testing

Streamlines the migration from Jest to Vitest and provides expert guidance for configuring high-performance TypeScript testing environments.

Quality Gates

Automates code quality validation by detecting project stacks and executing standardized formatting, linting, type-checking, and testing workflows.

Verification Before Completion

Enforces rigorous, evidence-based verification workflows before any claims of task completion or code correctness.

Systematic Debugging

Implements a rigorous, four-phase debugging methodology to identify root causes and prevent guesswork in software troubleshooting.
