Use when you need to apply functional programming principles in Java — including writing immutable objects and Records, pure functions, functional interfaces, lambda expressions, Stream API pipelines, Optional for null safety, function composition, higher-order functions, pattern matching for instanceof and switch, sealed classes/interfaces for controlled hierarchies, Stream Gatherers for custom operations, currying/partial application, effect boundary separation, and concurrent-safe functional…

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/'142-java-functional-programming' ] || [ -L ~/.agents/skills/'142-java-functional-programming' ]; then echo 'A skill folder named 142-java-functional-programming already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jabrena/plinth' "$d" && git -C "$d" checkout --quiet 'bbdd3f84aa085ab41151eb49d8da449762d32d83' -- 'skills/142-java-functional-programming' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/142-java-functional-programming' ~/.agents/skills/'142-java-functional-programming' && 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/'142-java-functional-programming' ~/.claude/skills/'142-java-functional-programming' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
