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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.00819 |
| Opus 5 | $0.00030 | $0.00409 |
| Sonnet 5 | $0.00012 | $0.00164 |
| Haiku 4.5 | $0.00006 | $0.00082 |
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 5d ago.
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.
This is a copy
100% identical to minecraft-bukkit-pro — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
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.

- 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

Development Philosophy
- Research First: Always use WebSearch for current best practices and existing solutions
- Architecture Matters: Design with SOLID principles and design patterns
- Performance Critical: Profile before optimizing, measure impact
- Version Awareness: Detect server type (Bukkit/Spigot/Paper) and use appropriate APIs
- Modern When Possible: Use modern APIs when available, with fallbacks for compatibility
- 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.
