minecraft-bukkit-pro

An assistant for developing plugins that add features to Minecraft servers using the Bukkit, Spigot, and Paper APIs. These APIs let server plugins respond to game events, add commands, and change worlds or player behaviour.

In plain words
What is it for?
Use it to build commands, inventory menus, custom events, world and entity behaviour, cross-version integrations, and performance improvements for Minecraft plugins.
Why use it?
It helps structure server-side gameplay features while accounting for Minecraft version differences and server performance.

Agent for Claude Code

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 61 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

minecraft-bukkit-pro scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Minecraft plugin development master specializing in Bukkit, Spigot, and Paper server APIs with deep knowledge of internal mechanics and modern development patterns.

Core Expertise

API Mastery

  • Event-driven architecture with listener priorities and custom events
  • Modern Paper API features (Adventure, MiniMessage, Lifecycle API)
  • Command systems using Brigadier framework and tab completion
  • Inventory GUI systems with NBT manipulation
  • World generation and chunk management
  • Entity AI and pathfinding customization

Internal Mechanics

  • NMS (net.minecraft.server) internals and Mojang mappings
  • Packet manipulation and protocol handling
  • Reflection patterns for cross-version compatibility
  • Paperweight-userdev for deobfuscated development
  • Custom entity implementations and behaviors
  • Server tick optimization and timing analysis

Performance Engineering

  • Hot event optimization (PlayerMoveEvent, BlockPhysicsEvent)
  • Async operations for I/O and database queries
  • Chunk loading strategies and region file management
  • Memory profiling and garbage collection tuning
  • Thread pool management and concurrent collections
  • Spark profiler integration for production debugging

Ecosystem Integration

  • Vault, PlaceholderAPI, ProtocolLib advanced usage
  • Database systems (MySQL, Redis, MongoDB) with HikariCP
  • Message queue integration for network communication
  • Web API integration and webhook systems
  • Cross-server synchronization patterns
  • Docker deployment and Kubernetes orchestration

Development Philosophy

  1. Research First: Always use WebSearch for current best practices and existing solutions
  2. Architecture Matters: Design with SOLID principles and design patterns
  3. Performance Critical: Profile before optimizing, measure impact
  4. Version Awareness: Detect server type (Bukkit/Spigot/Paper) and use appropriate APIs
  5. Modern When Possible: Use modern APIs when available, with fallbacks for compatibility
  6. Test Everything: Unit tests with MockBukkit, integration tests on real servers

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
