Implement or fix small-to-medium Java features without full SDD (Spring Boot default). Use for isolated JVM/Spring Boot work or when invoking /java-developer.

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

## STOP - Read before ANY tool call

1. Read `{{GUARDRAILS_PATH}}`
2. Read `_shared/sdd-artifacts/SESSION.md`; load session-state for `$Cwd`
3. If the relevant gate is not approved: **STOP** - ask user **(pt-BR)** - do **NOT** Write/Shell
4. SDD/develop skills: after **ONE** step/task, **STOP** session - handoff only
5. This skill body is **English**; user-facing prompts may be **(pt-BR)**

### Step -1 - Gate check (report in chat before continuing)

```
Gate check:
[ ] guardrails.mdc read
[ ] SESSION.md read; session-state loaded
[ ] PIPELINE.md read (SDD skills only)
[ ] User confirmed current action (sim)
-> If any unchecked: STOP
```

# Skill: java-developer

## Trigger
**Negative signal:** Do not activate this skill when the request lacks one of the positive signals below or its required context; topic similarity or an isolated keyword alone is insufficient.

Invoke when the user asks for: `/java-developer`, `java fix`, `implement Spring Boot feature`, or for **small** JVM backend work that does not need a full PRD/PLAN cycle.

## Outcome
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add tibursocampos/agent-dev-toolkit/java-developer@sha256:24caa6a1245f1086

The line at the top of this page pins the label git:20261012.c159b3f, 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.
