Migrate a Spring Boot 3.x application to Spring Boot 4.0 (Spring Framework 7, Jackson 3, modular starters, JSpecify). Use only for an explicit Boot 3.x to 4 migration, or to fix build or test failures caused by it, or to review one. Not for 3.x patch bumps or 4.0 to 4.1 upgrades; follow the target Boot version release notes and upgrade guide for those. Covers Maven and Gradle (Kotlin DSL, version catalogs).

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'spring-boot-4-migration' ] || [ -L ~/.agents/skills/'spring-boot-4-migration' ]; then echo 'A skill folder named spring-boot-4-migration already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/github/awesome-copilot' "$d" && git -C "$d" checkout --quiet '227949a7542a55d2155c00e7cdb998d9a0fee4f3' -- 'skills/spring-boot-4-migration' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/spring-boot-4-migration' ~/.agents/skills/'spring-boot-4-migration' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'spring-boot-4-migration' ~/.claude/skills/'spring-boot-4-migration' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
