Choose your Antigravity

Antigravity delivers native agentic assistance across purpose-built product surfaces, with dynamic reasoning controls, multi-agent orchestration, and enterprise-grade security. Evolved from the Agent Manager into a standalone desktop command center (Antigravity App) alongside native terminal, editor, and programmatic SDK interfaces, Antigravity supports both synchronous interactive pair-programming and asynchronous background agent workflows independent of a single IDE.

Add promo code validation and expired coupon checks to the checkout endpoint.

Worked for 11schevron_right

I updated checkout-service to validate discount codes before creating a payment intent:

PromoValidator: Check expiration dates and minimum order totals.
CheckoutController: Return 400 Bad Request with a clear message for expired codes.

Shall I run the checkout test suite to verify?

spring-petclinic / Project Analysis And Reporting

addmore_vert

Please review this project. Investigate how it works and build a report showing important files and data flows.

BaseEntity, NamedEntity, and Person serve as base classes.
Owner, Pet, Visit, Vet, Specialty, and PetType define business models.

Key System Controllers:

OwnerController: Manages owner creation, lookup, and pagination.
PetController: Handles pet updates/creation using PetValidator.
VetController: Provides HTML vet list and cached JSON endpoint.

Spring PetClinic - Architectural Review & Technical Analysis

This document provides an architecture review and technical investigation of the Spring PetClinic application (spring-projects/spring-petclinic).

1. Project Overview & Tech Stack

Spring PetClinic is a reference application built to showcase modern Spring Boot patterns, clean domain-driven architecture, and Java best practices.

Framework: Spring Boot 4.1.0, Spring MVC, Spring Data JPA, Spring Cache
Java Toolchain: Java 17 (build.gradle)
Database & Persistence: In-memory H2, MySQL, PostgreSQL

2. Core Domain Model & Entity Hierarchy

The domain model follows standard Object-Relational Mapping (ORM) principles with common base class inheritance.

Core agent capabilities

Every Antigravity surface runs on a shared, highly optimized agent harness co-trained with Gemini models, combining synchronous turn-by-turn code editing and tool execution with asynchronous background subagents, scheduled cron sidecars, and automated verification loops:
