SeedCraft

Your code. Your world.

Your Claude Code stats create a unique Minecraft world.

More messages = hotter biome. More tools = denser jungle. More hours = taller peaks.

The more you code, the more your world evolves — heavy projects produce scorching badlands, marathon sessions raise jagged peaks, and diverse tool usage warps the terrain into alien landscapes.

Your world is selected from a curated database of 500,000 real Minecraft seeds analyzed with Cubiomes across 46 biomes, ensuring the spawn biome genuinely matches your coding profile. Paste the seed into Minecraft and discover the world your code created.

Quick start

Install as a Claude Code plugin (recommended)

In Claude Code, run:

/plugin marketplace add syaor4n/seedcraft
/plugin install seedcraft@seedcraft

That's it. Type /craft to discover your Minecraft world.

The plugin auto-updates when you restart Claude Code.

Install from local clone

git clone https://github.com/syaor4n/seedcraft.git

Then in Claude Code:

/plugin marketplace add /path/to/seedcraft
/plugin install seedcraft@seedcraft

Standalone (no Claude Code needed)

git clone https://github.com/syaor4n/seedcraft.git
cd seedcraft
node --experimental-strip-types scripts/generate_seed.ts --all

Only requires Node.js 22+. No npm install, no dependencies.

How your coding shapes the world

Minecraft 1.18+ generates biomes using 6 climate parameters (temperature, humidity, continentalness, erosion, weirdness, depth). SeedCraft maps your Claude Code stats to these exact parameters, then finds a real seed whose spawn matches.

| What you do in Claude Code | What happens in Minecraft | Example | |---|---|---| | Send lots of messages | World gets hotter | 100K+ messages = desert, badlands | | Use lots of tools (Read, Edit, Bash...) | Vegetation gets denser | 50K+ messages + 30K+ tools = jungle | | Code for many hours | Mountains get taller | 300h+ = jagged peaks, frozen peaks | | Write & edit files frequently | More land, less ocean | 10K+ edits = far inland, continental | | Use many different tools | Terrain gets stranger | 70+ unique tools = ice spikes, cherry grove | | Delegate to subagents | Structures bar goes up | Visible in your climate profile card | | Work across many projects | Diversity bar goes up | Visible in your climate profile card |

The output ranges are calibrated to Minecraft's actual biome parameter space. A user with zero messages doesn't get "absolute zero" — they get a cold-but-real biome like snowy plains.

Usage

Skill commands

/craft                     # World from your current project (auto-detected from CWD)
/craft all                 # World from all your projects combined
/craft my-api              # World from a specific project
/craft unique              # 100% unique world hashed from your stats (biome is a surprise!)
/craft --list              # See all your projects

The skill also triggers on natural phrases like "create my minecraft world" or "what's my minecraft world".

Two modes

| Mode | What it does | Best for | |---|---|---| | Default (curated) | Creates your world from 500,000 pre-analyzed seeds across 46 biomes. Spawn biome is known and matches your coding profile. | Seeing how your coding style shapes a Minecraft world | | Unique (--unique) | SHA-256 hashes all your stats into a one-of-a-kind world. Biome is unknown — discover it! | Getting a world that's truly yours and only yours |

Standalone CLI

node --experimental-strip-types scripts/generate_seed.ts                     # Current project (auto-detect CWD)
node --experimental-strip-types scripts/generate_seed.ts --all               # All projects combined
node --experimental-strip-types scripts/generate_seed.ts --project "my-api"  # Specific project
node --experimental-strip-types scripts/generate_seed.ts --unique            # Unique hash-based seed
node --experimental-strip-types scripts/generate_seed.ts --all --unique      # Unique seed from all projects
node --experimental-strip-types scripts/generate_seed.ts --list              # List projects
node --experimental-strip-types scripts/generate_seed.ts --all --stats-only  # Climate profile only
node --experimental-strip-types scripts/generate_seed.ts --all --json        # JSON output

Fuzzy matching is supported: --project dashboard matches dashboard-v2, admin-dashboard, etc.

Loading your world in Minecraft

Java Edition

1. Open Minecraft Java Edition
2. Click Singleplayer > Create New World
3. Click More World Options...
4. Paste your seed number in the Seed for the World Generator field
5. Click Create New World

To verify: type /seed in the chat (works without cheats in Java singleplayer).

Bedrock Edition (Windows 10, Xbox, PlayStation, Switch, Mobile)

1. Open Minecraft > Play > Create New
2. Tap Create New World
3. Expand the Advanced section
4. Paste your seed number in the Seed field
5. Tap Create

Note: Bedrock Edition uses 32-bit seeds. SeedCraft prefers Bedrock-compatible seeds (shown as [Java & Bedrock] in the output). Seeds marked [Java only] will generate a different world on Bedrock.

Preview on Chunkbase (no Minecraft needed)

The output includes a Chunkbase link. Open it in any browser to:

1. See the full world map with all biomes color-coded
2. Find villages, temples, strongholds, and other structures
3. Locate your spawn point and plan your first base
4. Toggle specific biomes or structures with the Features panel

Make sure to select Java or Bedrock and the correct Minecraft version (1.21+) in Chunkbase for accurate results.

Examples

| Coding style | Biome | Why | |---|---|---| | The marathon coder — 175K messages, 67K tools, 385 hours | Wooded Badlands | Scorching heat from messages, towering mesas from marathon sessions | | The team lead — 55K messages, 20K tools, 110 hours | Wooded Badlands | Hot, humid, deep inland — intense multi-session leadership | | The builder — 18K messages, 7K tools, 52 hours | Stony Shore | Moderate warmth meets the rocky coast | | The explorer — 2.7K messages, 1K tools, read-heavy | Beach | Warm but few writes — the coastline of curiosity | | The weekend hacker — 1.4K messages, 3 hours | Snowy Plains | A quiet, pristine world waiting for footprints |

seedcraft.dev

The web companion for SeedCraft: seedcraft.dev

• Interactive demo — see how coding stats map to Minecraft climate parameters with live sliders
• Community gallery — browse and share worlds generated by other developers (seedcraft.dev/gallery)
• 500K seed database — the skill calls the API for matching against 500,000 curated seeds (with local fallback if offline)
• Biome tiers — discover which biomes are common, rare, and legendary

The skill automatically calls the seedcraft.dev API when online. If the API is unreachable, it falls back to the local 7K seed database — everything still works offline.
