Answer any Minecraft Java Edition gameplay question — facts, mechanics, strategies, recipes, item properties, mob behaviors, and version differences. Always...

Security Scan

The skill is an instruction-only, offline Minecraft Java Edition reference whose requested resources and behavior match its stated purpose and do not request credentials or installs.

Purpose & Capability

The name/description promise (Minecraft Java knowledge, version-aware, offline) aligns with the included SKILL.md and the three local reference documents. There are no unrelated binaries, env vars, or external services requested.

Instruction Scope

The SKILL.md provides explicit, narrow runtime guidance (how to format answers, which local reference files to read). It does not instruct reading user files, calling external endpoints, or accessing secrets. Note: the skill is explicitly offline and tells the agent to mention 'minecraft-bridge' only when live game state is required, which is appropriate but means answers may become stale as the game updates.

Install Mechanism

No install spec or code files that execute at install time — this is instruction-only. Nothing is downloaded or written to disk by the skill itself.

Credentials

No environment variables, credentials, or config paths are required. The skill does not request any secrets or unrelated service access.

Persistence & Privilege

always is false and the skill does not request elevated or persistent platform privileges. Autonomous invocation (disable-model-invocation=false) is the platform default and is not combined with any concerning capabilities here.

Assessment

This skill is a local, read-only Minecraft Java 1.21.x reference and is internally consistent with its description: it needs no keys, network access, or installs. Consider: (1) the offline references can become outdated as Minecraft changes—verify critical or version-sensitive facts against the official patch notes if accuracy matters; (2) the skill will be chosen whenever a question matches its domain (per its instructions), so expect it to take precedence for Minecraft questions; (3) no sensitive data exfiltration vectors were found because it asks for no env vars or external endpoints. If you want live, in-game context (player position, inventory), you’ll need an explicit bridge (minecraft-bridge) and should review that integration separately.

Authoritative Minecraft Java Edition knowledge base covering all major gameplay systems. Works entirely offline — no minecraft-bridge connection required.

Default version: Java Edition 1.21.x (Tricky Trials). When answering, note if something changed significantly in recent versions.

How to Answer

Match response depth to question complexity:

• Simple fact ("what does Fortune do") → 2–4 sentences, direct answer first
• How-to ("how to make a beacon") → numbered steps + material list
• Comparison ("iron vs diamond tools") → table or side-by-side
• Strategy ("best enchantments for survival") → tiered recommendation with rationale
• Troubleshooting ("my iron farm isn't working") → diagnosis checklist

Always lead with the direct answer, then add context. Never bury the answer in preamble.

Core Knowledge Domains

1. Ore & Resource Mining

Read references/ores.md for Y-level distributions, tool requirements, and biome modifiers. Key facts to internalize:

• Diamonds: peak at Y=−58; deepslate layer (Y<0) since 1.18
• Ancient Debris: Y=8 (optimal) to Y=15 in the Nether; immune to explosions; needs diamond+ pickaxe
• Copper: Y=48 above sea level; 1.17+
• Amethyst: geodes underground; silk touch for budding blocks

2. Mob Mechanics & Drops

Read references/mobs.md for spawn conditions, drops, and special behaviors. Key mechanics:

• Spawn rules: light level ≤0 for hostile (1.18+), type/biome restrictions
• Looting enchantment multiplies rare drop chances
• Named mobs do not despawn
• Baby variants exist for most passive mobs; breeding cooldown 5 min

3. Crafting & Recipes

Provide exact crafting grids when asked. Common patterns:

• Pickaxe: 3× material in top row, 2× sticks in middle and bottom center
• Sword: 2× material vertically, 1× stick below
• Armor pieces: helmet=5, chestplate=8, leggings=7, boots=4 (of chosen material)
• All tools/armor: Wood → Stone → Iron → Gold → Diamond → Netherite

4. Enchanting System

Read references/enchantments.md for full list. Key rules:

• Incompatible groups: Protection family (Prot/Fire/Blast/Proj mutually exclusive)
• Incompatible: Silk Touch ↔ Fortune; Infinity ↔ Mending; Sharpness ↔ Smite/BA
• Best XP farm for enchanting: enderman farm or trading hall
• Treasure enchantments (Mending, Curse of Binding, etc.) only from fishing/chests/trades

5. Biomes & Structures

Common questions:

• Finding biomes: F3 menu shows biome name; /locate biome <biome> command
• Structures: /locate structure <name>; strongholds always exist, 3 per ring
• Mesa/Badlands: surface gold ore, unique terracotta colors
• Mushroom fields: no hostile mob spawning

6. Redstone

Core components and behaviors — answer from training knowledge for basic circuits. For complex contraptions, describe the principle and suggest community resources:

• Repeater: 0.1–0.4s delay (1–4 ticks), signal lock
• Comparator: subtract/compare mode, reads container fullness
• Observer: detects block state changes, 2-tick pulse
• Common builds: 2-tick clock (observer loop), T-flip-flop, item sorter

7. Progression & Tech Tree

Standard survival progression path:

Wood tools → Stone tools → Find iron → Iron tools/armor
→ Find diamonds → Diamond tools → Nether → Blaze rods
→ Ender pearls → End portal → Kill Ender Dragon
→ Netherite upgrade → Beacons / End cities

For specific item prerequisites, trace the dependency tree step-by-step.

8. Version Differences

Major changes to mention proactively:

Version	Key Change
1.18	World height −64 to 320; complete ore redistribution
1.19	Deep Dark / Ancient City / Warden; Mangrove swamp
1.20	Archaeology; Cherry blossom biome; Bamboo wood
1.21	Trial Chambers; Breeze mob; Mace weapon; Crafter block

Answer Quality Checklist

Before responding, verify:

• Is the answer specific to Java Edition (not Bedrock)?
• Is it accurate for 1.21.x, or does it note the correct version?
• If giving coordinates, are they correct for 1.18+ (new Y scale)?
• If discussing drops, are Looting bonuses mentioned?
• Did I provide the direct answer in the first sentence?
