Helidon Bootstrap

Create Helidon SE and Helidon MP applications with REST endpoints, services, configuration, health checks, and tests.

Purpose

Give AI coding tools a reliable way to scaffold Helidon applications while keeping SE and MP programming models distinct.

Current status

In Progress on Grok.
Planned for GitHub Copilot and Claude Code.

Supported frameworks

Helidon (SE and MP)

Supported Java versions

Java 21 (preferred)
Java 17 (supported where required by the Helidon version)

Supported platform repositories

Platform	Repository	Status
Grok	java-for-grok	In Progress
GitHub Copilot	java-for-github-copilot	Planned
Claude Code	java-for-claude-code	Planned

Common use cases

Bootstrap a Helidon SE HTTP service
Bootstrap a Helidon MP JAX-RS application
Add configuration and health checks
Add service-layer structure and HTTP tests

Example prompts

Bootstrap a Helidon SE service using Java 21 and Maven with a greeting endpoint, configuration, health checks, and tests.

Create a Helidon MP application with a JAX-RS resource, CDI service, MicroProfile Config, and health endpoints.

Add integration tests that exercise the HTTP endpoints for this Helidon service.

SE vs MP variants differ; generated README content should state which model was chosen.

Installation or usage by platform

Install from java-for-grok.
Enable Helidon Bootstrap when the skill is marked Available in the repository.
State SE or MP explicitly in your prompt.
Build and run tests.

Limitations

SE/MP mixing is out of scope for bootstrap.
Observability and security hardening are follow-on skills/guides.
Status may move from In Progress to Available without a site redesign—check the repository and compatibility matrix.

Roadmap

Complete Grok packaging and validation
Copilot and Claude Code adaptations
