What it does

Create Code is an agent skill from rundeck/rundeck. Generate Java/Groovy/TypeScript code following Rundeck development standards. Auto-loads development guidelines, formatting rules, and testing requirements.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Commit messages and Test generation. It works with Java, TypeScript and Vue.js. The repository describes itself as: Enable Self-Service Operations: Give specific users access to your existing tools, services, and scripts. The licence is Apache-2.0.

Workflow steps

8 steps, taken from the step headings in SKILL.md.

Load Context
Understand Requirements
Write Test First
Implement Code
Format and Validate
Write Meaningful Commit Message
Define Config Type
Implement SystemConfigurable

What it can do on your machine

Read from SKILL.md and the folder at commit 9c3c82c. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- cbea.ms
- spockframework.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Create Code loads about 1.9k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 484 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~42
When it runs · the whole SKILL.md, loaded when a task matches: ~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Create Code Skill

When to Use

Creating new Java classes or Groovy services
Adding features to existing modules
Writing TypeScript/Vue components
Need to follow Rundeck code standards
Implementing new functionality with proper tests

Process

Phase 1: Load Context

Automatically read these documentation files:

.claude/docs/development-guidelines.md - Git commits, Groovy patterns, System Config, APIs
.claude/docs/code-formatting.md - Spotless rules, IDE setup
.claude/docs/testing-guidelines.md - Complete testing guide (Unit, API, UI, Functional)

Phase 2: Understand Requirements

Ask yourself:

What is being created? (Class, Service, Controller, Component)
What module does it belong to? (core, plugin, frontend)
What are the dependencies?
What behavior needs to be tested?

Phase 3: Write Test First

✅ ALWAYS write tests BEFORE implementation

For Groovy/Java:

Use Spock framework
Create *Spec.groovy test file
Use given/when/then blocks
Test should FAIL before implementation

For TypeScript/Vue:

Use Jest + Vue Test Utils
Create Component.spec.ts next to component
Test component behavior and interactions

Example Spock Test:

groovy

class UserServiceSpec extends Specification {
    
    def userService = new UserService()
    
    def "should return user when valid ID provided"() {
        given: "a valid user ID"
        def userId = 123
        
        when: "finding user by ID"
        def user = userService.findById(userId)
        
        then: "user is returned with correct ID"
        user != null
        user.id == userId
    }
    
    def "should throw exception when user not found"() {
        given: "an invalid user ID"
        def userId = 999
        
        when: "finding user by ID"
        userService.findById(userId)
        
        then: "exception is thrown"
        thrown(UserNotFoundException)
    }
}

Phase 4: Implement Code

Groovy/Java Standards

Use @CompileStatic:

groovy

@CompileStatic
class MyService {
    // your code
}

Use @GrailsCompileStatic for Grails components (Controllers, Services)
Use @CompileDynamic ONLY on specific methods that can't use static typing

Don't Implement Property Getters/Setters:

groovy

// Good - Groovy auto-generates getters/setters
class User {
    String name
    int age
}

// Bad - unnecessary boilerplate
class User {
    private String name
    String getName() { return name }
    void setName(String n) { name = n }
}

Use @Delegate When Appropriate:

groovy

class MyService implements SomeInterface {
    @Delegate
    SomeInterface wrapped
    // No need to implement SomeInterface methods
}

Avoid Commented-Out Code:

Delete it, don't comment it
Explain WHY in commit message
Version control preserves history

TypeScript/Vue Standards

Follow existing patterns in codebase
Use TypeScript types (no any)
Component props should be typed
Emit events with proper typing

Phase 5: Format and Validate

Format Code:

bash

# Fix formatting
./gradlew spotlessApply

Verify Build:

bash

# Quick verification (compilation + basic checks)
./gradlew verifyBuild

# Or full clean build (skips tests)
./gradlew clean && ./gradlew build -x check

Frontend Tests (if applicable):

bash

# Core UI
CORE_UI=rundeckapp/grails-spa/packages/ui-trellis
npm run --prefix "$CORE_UI" ci:test:unit

Note: Run the full test suite (./gradlew test) locally before considering work complete. CI will also run the complete test suite as an additional verification step.

Phase 6: Write Meaningful Commit Message

Your commit should complete: "If applied, this commit will ___"

Structure:

Short summary (50 chars or less)

Detailed explanation of what and why.
- Why this change was needed
- What the context was
- Any important details

Resources: How to Write a Git Commit Message

System Configuration Keys

If creating new System Configuration keys, follow 2-step process:

Show full SKILL.md (192 more words)Show less

Step 1: Define Config Type

Core: com.dtolabs.rundeck.core.config.RundeckConfigBase

Add nested field structure for your key (e.g., rundeck.a.b.mykey)

Step 2: Implement SystemConfigurable

Find appropriate Spring bean and implement SystemConfigurable interface

Return SysConfigProp objects in getSystemConfigProps() method

Use org.rundeck.app.config.SystemConfig builder:

groovy

SystemConfig.builder()
    .key("rundeck.feature.myfeature.enabled")
    .label("My Feature Enabled")
    .datatype("Boolean")
    .defaultValue("false")
    .authRequired("app_admin")  // or "ops_admin"
    .build()

See: .claude/docs/development-guidelines.md for complete details

Checklist

Before considering code complete:

Tests written first
Tests fail before implementation
Implementation follows Groovy/Java standards
@CompileStatic used (or @GrailsCompileStatic for Grails)
No commented-out code
Code formatted (./gradlew spotlessApply)
Build verified (./gradlew verifyBuild or ./gradlew clean && ./gradlew build -x check)
Meaningful commit message written

Examples

Example 1: Simple Service Class

groovy

@CompileStatic
class ProjectService {
    
    List<Project> listProjects() {
        // implementation
    }
    
    Project getProject(String name) {
        // implementation
    }
}

Test:

groovy

class ProjectServiceSpec extends Specification {
    
    def projectService = new ProjectService()
    
    def "should list all projects"() {
        when:
        def projects = projectService.listProjects()
        
        then:
        projects != null
        projects.size() >= 0
    }
}

Example 2: Grails Controller

groovy

@GrailsCompileStatic
class ProjectController {
    
    ProjectService projectService
    
    def index() {
        def projects = projectService.listProjects()
        respond projects
    }
}

Example 3: Using @Delegate

groovy

@CompileStatic
class CachedProjectService implements ProjectService {
    
    @Delegate
    ProjectService delegate
    
    private Cache cache
    
    // Override specific methods that need caching
    @Override
    Project getProject(String name) {
        cache.get(name) ?: delegate.getProject(name)
    }
}

Common Mistakes to Avoid

❌ Don't:

Write implementation before tests
Use @CompileDynamic on entire class
Commit commented-out code
Implement unnecessary getters/setters in Groovy
Write vague commit messages

✅ Do:

Write failing test first
Use @CompileStatic by default
Delete unused code (explain in commit)
Use Groovy properties
Write meaningful commit messages
