programming-java SKILL.md skillA
programming-java from muvon/octomind-tap is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add muvon/octomind-tap/programming-java@git:20261013.a69e0bbPins git:20261013.a69e0bb in mdr.lock. Pin the fingerprint instead.

Modern idiomatic Java best practices for AI coding agents: records, sealed types, pattern matching, virtual threads, and explicit failure contracts. Auto-activates in Java projects.
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
## Overview Use for Java implementation and review, especially modernizing verbose code without changing its contract. Keep the project's framework, build tool, and supported runtime; introduce newer features only when the configured release permits them. ## Mental model Make invalid states difficult to construct and ownership easy to see. Records reduce boilerplate, virtual threads simplify blocking concurrency, and neither removes the need for validation, bounded resources, or deliberate failure handling. ## Version gate As of 2026-10: JDK 27 (GA 2026-09-15) is the current feature release and Java 25 is the latest LTS. Recheck the vendor's support policy before choosing a runtime. Read Maven compiler release or Gradle toolchains, CI images, and deployment constraints; the installed JDK alone does not determine usable APIs. | Minimum release | Useful stable features | |---|---| | 17 | Records, sealed types, text blocks, instanceof patterns | | 21 | Record patterns, pattern switch, virtual threads | | 22 | Unnamed variables and patterns | | 24 | Stream gatherers; synchronized virtual-thread pinning fixed | …

How to install
mdr add muvon/octomind-tap/programming-java@sha256:1606620b04cebe92The line at the top of this page pins the label git:20261013.a69e0bb, 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.
