Plugins

A live Android device inside the conversation — emulator or USB phone, driven entirely through adb: 20 agent tools for streaming, Gradle build and run, UI-tree or OCR interaction, logcat, processes and memory, plus a three-button navigation panel.

Minecraft development skills and tools for DeepSeek Harness: 8 skills covering Paper/Spigot plugins, Fabric, Forge and NeoForge mods, addon development against major mods, and Gradle/JDK build setup across Minecraft 1.7.10 through 26.x; the mc_scaffold project generator and the mc_gradle Gradle runner; an intake skill that asks for missing version/platform details before starting; four built-in subagents; and a second Minecraft Architect preset whose mc_codex tool runs the user's own Codex CLI through the codex app-server protocol to draft the skeleton, after which DSH fills the marked method bodies and verifies the build.

Android development toolchain inside DeepSeek Harness: 23 android_* tools that find the SDK, create and manage AVDs, start and stop emulators, scaffold a Kotlin/Compose project, build and run it with Gradle, then install, launch, screenshot, tail logcat and drive the UI. A settings page holds the SDK, emulator, API-level, build and output parameters.

DSH plugin: offline JVM production-report diagnostics — thread dumps with Java-level deadlock cycles, GC-log pause percentiles, Maven/Gradle dependency conflicts, exception chains and Spring config diffs. Never touches a running process: no jcmd, no jstac

Scan project lockfiles (npm/pnpm/yarn/pip/go/cargo/maven/gradle/...) against the free OSV API and report confirmed dependency vulnerabilities with fix versions and remediation commands.
