What it does
Spring Boot Migration is an agent skill from rrezartprebreza/spring-boot-skills. Use when upgrading an application from Spring Boot 3.5 to Boot 4, completing a Framework 7 migration, replacing modular starters, adopting Jackson 3, or diagnosing post-upgrade failures.
Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `agents/openai.yaml`, `examples/bad-migration-plan.md` and `examples/good-migration-plan.md`).
It sits in Backend & APIs, covering Backend development. It works with Spring Boot. The repository describes itself as: Production-grade Claude Code and Codex skills for Spring Boot developers. The licence is MIT.
When your agent uses it
- Upgrading an application from Spring Boot 3.5 to Boot 4
- Completing a Framework 7 migration
- Replacing modular starters
- Adopting Jackson 3
Example prompts
- “/spring-boot-migration”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Add spring-boot-properties-migrator temporarily.
- Start every supported profile and fix each reported property.
- Remove the migrator before release.
- Compare /actuator/configprops, logging, JSON, and endpoint behavior against the baseline.
What it can do on your machine
Read from SKILL.md and the folder at commit f0c06a0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Spring Boot Migration loads about 734 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 332 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Use when upgrading an application from Spring Boot 3.5 to Boot 4, completing a Framework 7 migration, replacing modular starters, adopting Jackson 3, or diagnosing post-upgrade failures.
Spring Boot 4 Migration
Migrate from the latest Boot 3.5 release and keep business changes outside the upgrade diff.
Required baseline
- Use Java 17 or newer; prefer Java 21 for application builds.
- Use Spring Framework 7, Jakarta EE 11, and a Servlet 6.1-compatible container.
- Upgrade Kotlin to the supported baseline when applicable.
- Use a Boot 4-compatible Spring Cloud release train.
- Use GraalVM 25 or newer for native images.
Migrate modules and starters
Boot 4 splits infrastructure into focused modules and starters.
- Replace
spring-boot-starter-webwithspring-boot-starter-webmvc. - Use dedicated technology starters such as
spring-boot-starter-flyway. - Use technology-specific test starters; they bring the core test starter transitively.
- Use
spring-boot-starter-security-testfor Spring Security test support. - Use
spring-boot-starter-batch-jdbcwhen jobs require persistent metadata and restartability. - Use classic starters only as a temporary migration bridge, then remove them.
Migrate code
- Replace Jackson 2
com.fasterxml.jacksoncustomization with Jackson 3tools.jacksonAPIs. - Replace removed
@MockBeanand@SpyBeanwith framework Mockito bean overrides. - Add
@AutoConfigureMockMvcwhen a@SpringBootTestrequires MockMvc. - Replace removed or moved Boot package imports and deleted Boot 3 deprecations.
- Remove Undertow configuration and verify the selected server supports Servlet 6.1.
Configuration workflow
- Add
spring-boot-properties-migratortemporarily. - Start every supported profile and fix each reported property.
- Remove the migrator before release.
- Compare
/actuator/configprops, logging, JSON, and endpoint behavior against the baseline.
Verification
- Run unit, slice, integration, native, startup, and database migration tests as applicable.
- Verify JSON contracts, security failure responses, actuator exposure, and test slice composition.
- Inspect the dependency tree for old starters, duplicate Jackson generations, and unmanaged versions.
Examples
- See
examples/good-migration-plan.mdandexamples/bad-migration-plan.md.
Gotchas
- Agent keeps old starter names because compilation succeeds transitively - use Boot 4 dedicated starters.
- Agent adds both a technology test starter and the classic test starter - avoid duplicate test graphs.
- Agent leaves Jackson 2 and Jackson 3 customizations together - migrate the complete JSON boundary.
- Agent expects plain Batch starter metadata to persist - use the JDBC starter when restartability matters.
- Agent leaves the properties migrator or classic starters installed - remove temporary migration aids.
