Use first for every backend implementation task in this Spring Boot repo (Java 25, Spring Boot 4.1, JPA/MyBatis, JWT). Gives the start-to-finish workflow, where each kind of code goes, layering and transaction rules, and which domain skill to load next.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Backend Core — Playbook
> **Role:** HOW to run any backend task. Binding facts + evidence: `skills/backend/CORE.md` (read it after this file).
> **Global rules:** `AGENTS.md`. **Skill index:** `SKILLS.md`.
## 1. Before you edit
1. If a task file exists in `tasks/`, read it and set Resume State to `IN_PROGRESS` before touching code (`AGENTS.md §7`).
2. Pick the domain skills from the table in §4. Load only those.
3. Find the closest existing feature and trace it end to end:
```text
controller/api/{Model}Controller → service/{Model}Service → serviceImpl/{Model}ServiceImpl
→ repository/{Model}Repository (JPA) and/or mybatis/{Model}Mybatis + resources/mybatis/{Model}Mybatis.xml
+ model/{Model} dto/{Model}Dto mapper/{Model}Mapper validator/{Model}Validator
```
Good references: `AppRole*` (standard CRUD), `AiChat*` (owner-scoped rows), `FileManager*` (MyBatis paging + files).
4. Write down, before coding: the HTTP contract, who owns each write, the transaction boundary, and any non-DB side effect (file, vector, email, queue, remote call).
## 2. While you implement
…Read the whole file at its exact version.
How to install
mdr add bekaku/java-spring-boot-starter/backend-core@sha256:2fa3af40f3d34f11The line at the top of this page pins the label git:20261019.7c5a3db, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
