Install and run

Setup complexity: low.

clawhub skill install s17c4gq739k6px8k8sryevfm9h86myay:minecraft-custom-mod-builder

Setup complexity is classified as HIGH. You must provision dedicated cloud infrastructure or an isolated VM. Do not run this directly on your local workstation.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

Last updated: `2026-07-14`.

If the current date is more than 7 days after the last updated date, reinstall this skill from skills.sh or ClawHub before relying on endpoints, schemas, setup steps, or examples.

## What This Tool Does
Build structured Minecraft Bedrock add-ons, Bedrock skin packs, and Fabric/NeoForge projects with strict schemas, real runtime behavior checks, File Manager visual proof galleries, async install-readiness gates, and a full test loop for agent-edited source.

## Product Instructions
### Minecraft Mod Builder

Generate deterministic Minecraft Bedrock, Fabric, and NeoForge mod artifacts from structured specifications. This tool does not call an LLM, does not accept prompts, and does not require user credentials.

#### Two Rules That Will Save You Many Retries

##### Rule 1 — One ItemSpec equals one in-game item

A single `ItemSpec` produces one in-game item. The fields `damage`, `durability`, `max_stack_size`, `nutrition`, `tool`, `armor`, `food`, `block_placer`, `entity_placer`, `enchantable`, `repairable`, `digger`, `cooldown`, `glint`, `rarity`, `dyeable`, and `component_overrides` all attach to the *same item*. A weapon does **not** need a separate entity or a separate "damage item." A sword does **not** need a partner "enchantment item." You ship one item; this tool wires up every relevant Minecraft component on that item from the fields above.

Do not split one weapon idea across many `items[]` entries. Do not duplicate a weapon and call one copy "damage" and another "durability." That is the most common source of bloated, broken submissions.

##### Rule 2 — Every visible asset requires a texture

Items, blocks, entities, particles, named texture assets, machines, storage, and skin-pack skins must each carry a `texture` with one of these three sources:

* `source_base64` — base64-encoded PNG or JPEG bytes (max 1024×1024, max 5 MB).
* `source_file_id` — a File Manager file_id for a user-uploaded image.
* `color_hex` — an explicit `#RRGGBB` color. Only `item_kind in

Parameters:

| Parameter | Type | Required | Description |
|---|---|---|---|
| `advanced_resources` | `array` | no | Non-executable data/resource files or Bedrock .mcfunction files. Java source and Bedrock JavaScript are rejected. |
| `allow_experimental_bedrock_features` | `boolean` | no | Allow Bedrock experimental features when required. |
| `assets` | `object` | no | Optional textures, sounds, particles, models, and language entries. |
| `authoring_mode` | `string` | no | Typed declarative generation mode. Agent-edited code must use start_build_job with source_archive_file_id. |
| `build_jar` | `boolean` | no | Fabric/NeoForge only. Build jar when true. |
| `compatibility_mode` | `string` | no | Strict platform fidelity. Platform-mismatched features are rejected, never dropped. |
| `description` | `string` | no | Short mod description. |
| `features` | `object` | no | FeatureSet object. Use arrays such as items, blocks, entities, events, commands, client_modules, machines, recipes, particles, sounds, functions, storage, worldgen, scoreboards, biomes, dimensions, effects, and skins. See get_instructions for nested fields. |
| `fidelity_policy` | `string` | no | Preserve intent by default. acknowledged_approximation is valid only after explicit user approval of a fully implemented alternative; placeholders are never accepted. |
| `include_file_preview` | `boolean` | no | Include capped text previews in generated_files. |
| `minecraft_version` | `string` | no | Pinned version. Omit unless explicitly needed. |
| `mod_id` | `string` | yes | Lowercase namespace matching ^[a-z][a-z0-9_]{1,63}$. |

| `mod_name` | `string` | yes | Human-readable mod name. |
| `output_mode` | `string` | no | installable, source, or both. |
| `skin_pack` | `object` | no | Skin pack definition for target_platform=bedrock_skinpack. |
| `target_platform` | `string` | yes | bedrock, bedrock_skinpack, fabric, or neoforge. |
| `user_intent_summary` | `string` | no | Optional concise intent statement for deterministic classification; not used for silent reinterpretation. |
| `validate_output` | `boolean` | no | Ru

## Description:

Minecraft Custom Mod Builder helps agents generate and verify structured Minecraft Bedrock add-ons, Bedrock skin packs, and Fabric or NeoForge projects through AgentPMT-hosted tool calls.

This skill is ready for commercial/non-commercial use.

## Publisher:

[agentpmt](https://clawhub.ai/user/agentpmt)

### License/Terms of Use:

MIT-0

## Use Case:

Developers and external agent users use this skill to create installable or source Minecraft mod projects from structured specifications, then check runtime behavior, visual proof, and install readiness before delivery.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: A third-party hosted service may receive Minecraft specifications, images, and optional source archives.

Mitigation: Avoid confidential code, private assets, credentials, wallet secrets, and payment headers in prompts, archives, and logs; review AgentPMT setup and storage terms before use.

Risk: Some supported client and ESP-style features can be used for multiplayer cheating, griefing, or surveillance.

Mitigation: Use these capabilities only in authorized, test, single-player, or server-owner-approved contexts and decline requests intended for abuse.

Risk: The server security review flagged the release for review before installation, including mutable setup commands.

Mitigation: Prefer pinned installation commands or trusted OpenClaw installation paths, and review and scan the skill before deployment.
