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 cod…

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

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 verifyormvn clean verifyafter 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.
