Claude CodeCursorClineWindsurfCodexGoose

What it does

Identifies methods exceeding complexity thresholds (LOC > 15, statements > 10, cyclomatic complexity > 10) and extracts logical code blocks into focused helper methods
Produces fully compilable Java 17 code with descriptive method names and single-line documentation comments
Preserves all original functionality while reducing cognitive load and improving testability through smaller, single-responsibility

How to use java-refactoring-extract-method on Cursor

AI-first code editor with Composer

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your machine
›Node.js 16+ with npm — verify with node --version
›Active project directory where you want to add java-refactoring-extract-method

Run the install command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/github/awesome-copilot --skill java-refactoring-extract-method

Fetches java-refactoring-extract-method from github/awesome-copilot and configures it for Cursor.

Select Cursor when prompted

The CLI shows a list of agents. Use arrow keys and space to select Cursor:

◆ Which agents do you want to install to?

│

│ ── Universal (.agents/skills) ────────────────

│ · Cline · Codex · Goose · Windsurf

│ ●Cursor(selected)

│ · Cursor · Aider · Continue

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/java-refactoring-extract-method

Restart Cursor to activate java-refactoring-extract-method. Access via /java-refactoring-extract-method in your agent's command palette.

Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Code After Refactoring 1:

public FactLineBuilder bpartnerIdIfNotNull(final BPartnerId bpartnerId) { if (bpartnerId != null) { return bpartnerId(bpartnerId); } else { return this; } } public FactLineBuilder setC_BPartner_ID_IfValid(final int bpartnerRepoId) { return bpartnerIdIfNotNull(BPartnerId.ofRepoIdOrNull(bpartnerRepoId)); }

Code Before Refactoring 2:

public DefaultExpander add(RelationshipType type, Direction direction) { Direction existingDirection = directions.get(type.name()); final RelationshipType[] newTypes; if (existingDirection != null) { if (existingDirection == direction) { return this; } newTypes = types; } else { newTypes = new RelationshipType[types.length + 1]; System.arraycopy(types, 0, newTypes, 0, types.length); newTypes[types.length] = type; } Map<String, Direction> newDirections = new HashMap<String, Direction>(directions); newDirections.put(type.name(), direction); return new DefaultExpander(newTypes, newDirections); }

Code After Refactoring 2:

Task

Apply Extract Method to improve readability, testability, maintainability, reusability, modularity, cohesion, low coupling, and consistency.

Always return a complete and compilable method (Java 17).

Perform intermediate steps internally:

First, analyze each method and identify those exceeding thresholds:

LOC (Lines of Code) > 15
NOM (Number of Statements) > 10
CC (Cyclomatic Complexity) > 10

For each qualifying method, identify code blocks that can be extracted into separate methods.

Extract at least one new method with a descriptive name.

Output only the refactored code inside a single java block.

Do not remove any functionality from the original method.

Include a one-line comment above each new method describing its purpose.
