spring-plugin AGENTS.md

A contributor guide for Explyt Spring, an IntelliJ plugin that adds Spring, Quarkus, and JPA support to the IDE. It explains the Kotlin, Gradle, and multi-module project structure.

In plain words
What is it for?
Use it when changing plugin modules, running the sandbox IDE, executing tests, building the plugin ZIP, or following the project's code and contribution conventions.
Why use it?
It shows where different features live and which commands build, test, run, and package the plugin.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

spring-plugin AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Contributor Guide

Explyt Spring: a multi-module IntelliJ Platform plugin for Spring/Quarkus/JPA support. Kotlin 2.3.20, JDK 21, Gradle. Public open-source project (Apache-2.0): https://github.com/explyt/spring-plugin — issues, discussions, and PRs live there.

Project structure

  • modules/<name>/ — one Gradle module each, configured by modules/<name>/<name>.gradle.kts (not build.gradle.kts).
  • spring-core owns the bean model, inspections, navigation, properties, statistics — most changes land here. Feature modules (spring-web, spring-data, spring-security, …) match their names. base is Spring-agnostic shared utilities; test-framework holds test fixtures; spring-bootstrap is assembly-only (no feature code).
  • Sources: modules/<name>/src/main/kotlin/com/explyt/...; tests: src/test/kotlin; test data: modules/<name>/testdata/.
  • explyt-spring-boot-bean-reader/ is a separate Maven project (runtime javaagent for Native Context Mode).

Build, test, run

./gradlew :spring-bootstrap:runIde       # launch sandbox IDE (root runIde is disabled)
./gradlew :spring-bootstrap:buildPlugin  # ZIP → modules/spring-bootstrap/build/distributions/
./gradlew :spring-core:test              # one module's tests
./gradlew :spring-core:test --tests "com.explyt.spring.core.inspections.kotlin.SpringKotlinObjectInspectionTest"

Tests are IntelliJ Platform tests (headless IDE fixture) — slow and single-forked by design.

Code style and conventions

  • Kotlin-idiomatic code; match surrounding style. Every source file starts with the Apache-2.0 SPDX header (Copyright (c) 2024 Explyt Ltd).
  • User-visible strings go through module message bundles (SpringCoreBundle, …); Spring FQNs come from constants holders like SpringCoreClasses.
  • IntelliJ threading rules apply: no slow work on EDT, PSI access under read/write actions, re-throw ProcessCanceledException, use SmartPsiElementPointer across async boundaries.
  • New inspections extend existing base classes (e.g. SpringBaseUastLocalInspectionTool), live in <module>/inspections/, and are registered in the module's plugin.xml. Reference pair: SpringKotlinObjectInspection.kt + its test.
  • Inspection tests use test-framework base classes (ExplytInspectionKotlinTestCase, …), declare libraries: Array<TestLibrary>, and usually have Java and Kotlin twins under inspections/java/ and inspections/kotlin/. Add or update tests for any behavior change.
  • Track new user-facing actions via StatisticActionId + StatisticService.addActionUsage(...).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
