Comprehensive testing and development workflow specialist combining DDD testing, characterization tests, performance profiling, and quality assurance. Use when writing tests or measuring coverage.
Unified Development Workflow provides comprehensive development lifecycle management combining DDD testing, AI-powered debugging, performance optimization, automated code review, and quality assurance into integrated workflows.
Core Capabilities:
Workflow Progression: Debug stage leads to Refactor stage, which leads to Optimize stage, then Review stage, followed by Test stage, and finally Profile stage. Each stage benefits from AI-powered analysis and recommendations.
When to Use:
Unified Development Philosophy:
Workflow Components:
Component 1 - AI-Powered Debugging: The debugging component provides intelligent error classification and solution recommendations. When an error occurs, the system analyzes the error type, stack trace, and surrounding context to identify root causes and suggest appropriate fixes. The debugger references current best practices and common error resolution patterns.
Component 2 - Smart Refactoring: The refactoring component performs technical debt analysis and identifies safe automated transformation opportunities. It evaluates code complexity, duplication, and maintainability metrics to recommend specific refactoring actions with risk assessments.
Component 3 - Performance Optimization: The performance component provides real-time monitoring guidance and bottleneck detection. It helps identify CPU-intensive operations, memory leaks, and I/O bottlenecks, then recommends specific optimization strategies based on the identified issues.
Component 4 - DDD Testing Management: The DDD testing component provides specialized testing approaches aligned with domain-driven development. For legacy code, it uses characterization tests to capture current behavior before refactoring (PRESERVE phase). For greenfield projects, it uses specification tests derived from domain requirements. Behavior snapshots ensure behavioral consistency during transformations, and TRUST 5 validation ensures quality standards are maintained.
Component 5 - Automated Code Review: The code review component applies TRUST 5 framework validation with AI-powered quality analysis. It evaluates code against five trust dimensions and provides actionable improvement recommendations.
The TRUST 5 framework is a conceptual quality assessment model with five dimensions. This framework provides guidance for evaluating code quality, not an implemented module.
Dimension 1 - Testability: Evaluate whether the code can be effectively tested. Consider whether functions are pure and deterministic, whether dependencies are injectable, and whether the code is modular enough for unit testing. Scoring ranges from low testability requiring significant refactoring to high testability with excellent test coverage support.
Dimension 2 - Readability: Assess how easily the code can be understood by others. Consider whether variable and function names are descriptive, whether the code structure is logical, and whether complex operations are documented. Scoring evaluates naming conventions, code organization, and documentation quality.
Dimension 3 - Understandability: Evaluate the conceptual clarity of the implementation. Consider whether the business logic is clearly expressed, whether abstractions are appropriate, and whether a new developer can understand the code quickly. This goes beyond surface readability to assess architectural clarity.
Dimension 4 - Security: Assess security posture and vulnerability exposure. Consider whether inputs are validated, whether secrets are properly managed, and whether common vulnerability patterns are avoided including injection, XSS, and CSRF. Scoring evaluates adherence to security best practices.
Dimension 5 - Transparency: Evaluate operational visibility and debuggability. Consider whether error handling is comprehensive, whether logs are meaningful and structured, and whether issues can be traced through the system. Scoring assesses observability and troubleshooting capabilities.
Overall TRUST Score Calculation: The overall TRUST score combines all five dimensions using weighted averaging. Critical issues in any dimension can override the average, ensuring security or testability problems are not masked by high scores elsewhere. A passing score typically requires minimum thresholds in each dimension plus an acceptable weighted average.

Enterprise Development Workflow: For enterprise applications, the workflow integrates quality gates at each stage. Before deployment, the code must pass minimum TRUST score thresholds, have zero critical issues identified, and meet required test coverage percentages. The quality gates configuration specifies minimum trust scores (typically 0.85), maximum allowed critical issues (typically zero), and required coverage levels (typically 80 percent).
Performance-Critical Applications: For performance-sensitive systems, the workflow emphasizes profiling and optimization stages. Performance thresholds define maximum acceptable response times, memory usage limits, and minimum throughput requirements. The workflow provides percentage improvement tracking and specific optimization recommendations.
Continuous Integration Integration: The workflow integrates with CI/CD pipelines through a multi-stage validation process.
Stage 1 - Code Quality Validation: Run the code review component and verify results meet quality standards. If the quality check fails, the pipeline terminates with a quality failure report.
Stage 2 - Testing Validation: Execute the full test suite including unit, integration, and end-to-end tests. If any tests fail, the pipeline terminates with a test failure report.
Stage 3 - Performance Validation: Run performance tests and compare results against defined thresholds. If performance standards are not met, the pipeline terminates with a performance failure report.
Stage 4 - Security Validation: Execute security analysis including static analysis and dependency scanning. If critical vulnerabilities are found, the pipeline terminates with a security failure report.
Upon passing all stages, the pipeline generates a success report and proceeds to deployment.
Quality gates define the criteria that must be met at each workflow stage. Gates can be configured with different strictness levels.
Strict Mode: All quality dimensions must meet or exceed thresholds. Any critical issue blocks progression. Full test coverage requirements apply.
Standard Mode: Average quality score must meet threshold. Critical issues block progression, but warnings are allowed. Standard coverage requirements apply.
Lenient Mode: Only critical blocking issues prevent progression. Quality scores generate warnings but do not block. Reduced coverage requirements apply.
Gate configuration includes threshold values for each TRUST dimension, maximum allowed issues by severity, required test coverage levels, and performance benchmark targets.
The workflow supports development across multiple programming languages with language-specific adaptations.
Python Projects: Integration with pytest for testing, pylint and flake8 for static analysis, bandit for security scanning, and cProfile or memory_profiler for performance analysis.
JavaScript and TypeScript Projects: Integration with Jest or Vitest for testing, ESLint for static analysis, npm audit for security scanning, and Chrome DevTools or lighthouse for performance analysis.
Go Projects: Integration with go test for testing, golint and staticcheck for static analysis, gosec for security scanning, and pprof for performance analysis.
Rust Projects: Integration with cargo test for testing, clippy for static analysis, cargo audit for security scanning, and flamegraph for performance analysis.
The PR Code Review process uses a multi-agent architecture following the official Claude Code plugin pattern.
Eligibility Check Agent using Haiku: The Haiku agent performs lightweight filtering to avoid unnecessary reviews. It checks the PR state and metadata to determine if review is warranted. Skip conditions include closed PRs, draft PRs, PRs already reviewed by bot, trivial changes like typo fixes, and automated dependency updates.
Context Gathering: Before launching review agents, the system gathers relevant context by finding CLAUDE.md files in directories containing modified code to understand project-specific coding standards. It also generates a concise summary of PR changes including files modified, lines added or removed, and overall impact assessment.
Parallel Review Agents using five Sonnet instances: Five Sonnet agents run in parallel, each focusing on a specific review dimension. Agent 1 audits CLAUDE.md compliance checking for violations of documented coding standards and conventions. Agent 2 scans for obvious bugs including logic errors, null reference risks, and resource leaks. Agent 3 provides git blame and history context to identify recent changes and potential patterns. Agent 4 checks previous PR comments for recurring issues and unresolved feedback. Agent 5 validates code comment compliance ensuring comments are accurate and helpful.
Confidence Scoring System: Each detected issue receives a confidence score from 0 to 100. A score of 0 indicates a false positive with no confidence. A score of 25 means somewhat confident but might be real. A score of 50 indicates moderately confident that the issue is real but minor. A score of 75 means highly confident that the issue is very likely real. A score of 100 indicates absolutely certain that the issue is definitely real.
Filter and Report Stage: Issues below the 80 confidence threshold are filtered out to reduce noise. Remaining issues are formatted and posted to the PR using the GitHub CLI. The output format follows a standardized markdown structure with issue count, numbered list of issues with descriptions, and direct links to code with specific commit SHA and line range.
Example PR Review Output: The review output begins with a Code review header, followed by the count of found issues. Each issue is numbered and includes a description of the problem with reference to the relevant CLAUDE.md rule, followed by a link to the specific file, line range, and commit SHA in the pull request.
The workflow leverages industry-standard tools for each capability area.
Analysis Libraries: cProfile provides Python profiling and performance analysis. memory_profiler enables memory usage analysis and optimization. psutil supports system resource monitoring. line_profiler offers line-by-line performance profiling.
Static Analysis Tools: pylint performs comprehensive code analysis and quality checks. flake8 enforces style guide compliance and error detection. bandit scans for security vulnerabilities. mypy validates static types.
Testing Frameworks: pytest provides advanced testing with fixtures and plugins. unittest offers standard library testing capabilities. coverage measures code coverage and identifies untested paths.
The workflow integrates with GitHub Actions through a multi-step job configuration.
Job Configuration Steps:
The job can be configured to run on push and pull request events, with matrix testing across multiple Python versions if needed.
For containerized environments, the workflow executes within Docker containers.
Container Configuration: Base the image on a Python slim variant for minimal size. Install project dependencies from requirements file. Copy project source code into the container. Configure entrypoint to execute the complete workflow sequence. Mount volumes for result output if persistent storage is needed.
The containerized workflow ensures consistent execution environments across development, testing, and production systems.
