What is spring-ecosystem-docs?

A reference guide for building Java applications with Spring Boot and the Spring Framework. It explains related Spring tools for web applications, security, databases, testing, dependency injection, and reactive programming.

It helps with auto-configuration, dependency injection, web MVC and WebFlux, security, database access through JPA or MongoDB, Redis, REST services, and testing.

It gives the coding agent definitions and patterns for Spring concepts, reducing confusion when configuring or extending a Spring application.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00043	$0.01366
Opus 5.5	$0.00017	$0.00546
Sonnet 5.5	$0.00009	$0.00273

Security

Grade A, and why

spring-ecosystem-docs 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 2mo 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.

Spring Framework Ecosystem

Overview

Spring is the most widely-used Java application framework for building enterprise applications. It provides comprehensive infrastructure support for developing Java applications, with a focus on inversion of control (IoC), dependency injection (DI), aspect-oriented programming (AOP), and modular project structure.

The Spring ecosystem consists of multiple projects that build on the Spring Framework core:

Spring Boot - Stand-alone, production-grade applications with auto-configuration and embedded servers
Spring Framework - Core IoC container, AOP, web MVC, WebFlux, data access, testing
Spring Security - Authentication, authorization, OAuth2, CSRF, session management
Spring Data - Repository abstractions for JPA, MongoDB, Redis, JDBC, REST, and more

Key Concepts

Inversion of Control (IoC) - Objects define their dependencies through constructor arguments, factory methods, or setters; the container injects them
Dependency Injection (DI) - The Spring container manages bean lifecycle and wires dependencies
Beans - Objects managed by the Spring IoC container
ApplicationContext - The central interface for configuration and bean management
Auto-configuration - Spring Boot automatically configures beans based on classpath dependencies
Starters - Opinionated dependency descriptors that simplify build configuration
Actuator - Production-ready features: health checks, metrics, monitoring via HTTP/JMX
Externalized Configuration - Properties/YAML files, environment variables, command-line args
AOP - Cross-cutting concerns like transactions, logging, security via aspects
Spring MVC - Servlet-stack web framework with annotation-based controllers
Spring WebFlux - Reactive-stack web framework built on Reactor
Repository abstraction - Spring Data's pattern for data access with minimal boilerplate

Project Structure

A typical Spring Boot application:

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

spring-ecosystem-docs is a skill published in the GitHub repository pledgeandgrow/pledge-skills (10 stars, last pushed 3mo ago), licensed MIT. It adds 43 tokens to every session and 1,366 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
