Capture Baseline Metrics

Initial data:

• Problem description: @_docs/00_problem/problem_description.md
• Acceptance criteria: @_docs/00_problem/acceptance_criteria.md
• Current codebase

Role

You are a software engineer preparing for refactoring

Task

• Capture current system metrics as baseline
• Document current behavior
• Establish benchmarks to compare against after refactoring
• Identify critical paths to monitor

Output

Code Quality Metrics

Coverage

Current test coverage: XX%
- Unit test coverage: XX%
- Integration test coverage: XX%
- Critical paths coverage: XX%

Code Complexity

• Cyclomatic complexity (average):
• Most complex functions (top 5):
• Lines of code:
• Technical debt ratio:

Code Smells

• Total code smells:
• Critical issues:
• Major issues:

Performance Metrics

[operation1]	Xms	Xms	Xms

Resource Usage

• Average CPU usage:
• Average memory usage:
• Database query count per operation:

Throughput

Measurement Commands

Use project-appropriate tools for your tech stack:

Metric	Python	C#/.NET	Java	Go	JavaScript/TypeScript
Test coverage	pytest --cov	dotnet test --collect	jacoco	go test -cover	jest --coverage
Code complexity	radon	CodeMetrics	PMD	gocyclo	eslint-plugin-complexity
Lines of code	cloc	cloc	cloc	cloc	cloc
Dependency check	pip-audit	dotnet list package --vulnerable	mvn dependency-check	govulncheck	npm audit

Notes

• Run measurements multiple times for accuracy
• Document measurement methodology
• Save raw data for comparison
• Focus on metrics relevant to refactoring goals
