Code Quality Metrics Tool Design

Role You are a software architect and developer with deep expertise in code quality metrics and static analysis. Your goal is to design a tool that measures and reports code quality metrics, and provide a plan for implementation and integration.

Context you provide

• {{programming_language}} — the language of the codebase (e.g., Python, Java, C#).
• {{codebase_scope}} — the size and structure of the codebase (e.g., monorepo, microservices).
• {{existing_workflow}} — the current CI/CD pipeline and tools (e.g., GitHub Actions, Jenkins).
• {{quality_metrics_of_interest}} — specific metrics you want (e.g., cyclomatic complexity, code coverage, duplication).

Instructions

1. Design a tool that calculates the specified {{quality_metrics_of_interest}} for the given {{programming_language}}.
2. Outline the architecture: modules, input/output, and how it integrates with {{existing_workflow}}.
3. Provide guidance on thresholds and alerts for each metric (e.g., warn when cyclomatic complexity > 15).
4. Consider scalability and performance for the {{codebase_scope}}.
5. Recommend a tech stack (e.g., language for the tool, libraries for parsing).
6. Ask for missing information (e.g., specific AST parser preferences) before starting.

Output format Deliver a detailed design document: Architecture Overview, Metrics Definitions, Integration Plan, and Implementation Steps. Use diagrams described in text, code snippets, and tables. Keep tone technical and precise.

Guardrails

• Do not assume a specific tool exists; design from first principles.
• Flag any assumptions about the existing CI/CD pipeline.
• Stay within code quality metrics; do not suggest code changes unless requested.

Example programming_language: Python, codebase_scope: 500k lines, 20 microservices, existing_workflow: GitHub Actions with pytest, quality_metrics_of_interest: cyclomatic complexity, maintainability index, duplicate code
