163 Java Profiling Refactor

Use when you need to refactor Java code based on profiling analysis findings — including reviewing docs/profiling-problem-analysis and docs/profiling-solutions, identifying specific performance bottlenecks, and implementing targeted code changes to address CPU, memory, or threading issues. This should trigger for requests such as Refactor the code with profiling; Apply profiling; Refactor the code with profiling; Optimize hot path. Part of cursor-rules-java project

Java Profiling Workflow / Step 3 / Refactor code to fix issues

Implement refactoring based on profiling analysis: review profiling-problem-analysis-YYYYMMDD.md and profiling-solutions-YYYYMMDD.md, identify specific performance bottlenecks, and refactor code to fix them. Ensure all tests pass after changes.

What is covered in this Skill?

Review analysis notes: docs/profiling-problem-analysis-YYYYMMDD.md, docs/profiling-solutions-YYYYMMDD.md
Identify specific bottlenecks from the documented findings
Refactor code to address CPU hotspots, memory leaks, threading issues, or other performance problems
Run verification: ./mvnw clean verify or mvn clean verify

Scope: Changes must pass all tests. Apply fixes incrementally and verify after each significant change.

Constraints

Verify that changes pass all tests before considering the refactoring complete.

MANDATORY: Run ./mvnw clean verify or mvn clean verify after applying refactoring
SAFETY: If tests fail, fix issues before proceeding
BEFORE APPLYING: Read the analysis and solutions documents for specific recommendations
EDGE CASE: If request scope is ambiguous, stop and ask a clarifying question before applying changes
EDGE CASE: If required inputs, files, or tooling are missing, report what is missing and ask whether to proceed with setup guidance

When to use this skill

Refactor the code with profiling
Apply profiling
Refactor the code with profiling
Optimize hot path
Performance refactoring

Workflow

Review profiling analysis artifacts

Read docs/profiling-problem-analysis-YYYYMMDD.md and docs/profiling-solutions-YYYYMMDD.md to select target bottlenecks.

Apply targeted performance refactors

Implement focused code changes for documented CPU, memory, or threading hotspots, incrementally and safely.

Verify behavior and performance build integrity

Run ./mvnw clean verify or mvn clean verify; if tests fail, fix issues before continuing.

Prepare handoff for verification phase

Summarize implemented changes and expected metric improvements for Step 4 comparison.
