debug-addonFind and fix problems in a Minecraft Bedrock Edition add-on (behavior packs and resource packs) using Minecraft Creator Tools validation.
Debug Addon is an agent skill from Mojang/minecraft-creator-tools. Find and fix problems in a Minecraft Bedrock Edition add-on (behavior packs and resource packs) using Minecraft Creator Tools validation. Use this whenever someone asks why their add-on, pack, mob, item, block, or texture isn't working, won't load, is invisible, shows a missing texture or raw name like item.foo:bar, has Content Log errors, fails validation, needs upgrading to current Minecraft versions, or needs checking and packaging as a .mcaddon for release. Also use it right after creating or changing add-on…
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts, reference files and assets (for example `agents/openai.yaml`, `references/content-log.md` and `references/runtime-symptoms.md`).
It works with Java and Home Assistant. The repository describes itself as: A set of tools for creating content and add-ons for Minecraft Bedrock Edition.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit a8f2cd2. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 3 files in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
npxnodeFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Debug Addon loads about 1.8k tokens when it runs, and up to ~4.8k if it reads all its reference files. Until then it costs about 172 tokens; SKILL.md has 882 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 882 words (~1,755 tokens).
“Validation catches most packaging and reference mistakes, so start there, then fall back to the runtime checklist for problems validation can't see. Keep going until validation reports zero errors, then tell the user what you changed.”

Find and fix problems in a Minecraft Bedrock Edition add-on (behavior packs and resource packs) using Minecraft Creator Tools validation. Debug Addon is an agent skill from Mojang/minecraft-creator-tools. Find and fix problems in a Minecraft Bedrock Edition add-on (behavior packs and resource packs) using Minecraft Creator Tools validation.
Run `npx skills add Mojang/minecraft-creator-tools --skill debug-addon -a claude-code`. Or copy the skill folder (plugins/minecraft/skills/debug-addon in Mojang/minecraft-creator-tools) into .claude/skills/debug-addon in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Mojang/minecraft-creator-tools --skill debug-addon -a codex`. Or copy the skill folder (plugins/minecraft/skills/debug-addon in Mojang/minecraft-creator-tools) into .agents/skills/debug-addon in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Mojang/minecraft-creator-tools --skill debug-addon -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/debug-addon, .gemini/skills/debug-addon, .github/skills/debug-addon and .opencode/skills/debug-addon in your project.
Going by SKILL.md and its folder, Debug Addon needs JavaScript for the scripts in its folder and the command-line tools its instructions call (npx and node). Our summary lists: Node.js.
SKILL.md contains no URLs. Its commands use npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Debug Addon has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 1.8k tokens (SKILL.md is roughly 7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3.1k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Debug Addon: Brainstorming (xpinjection/test-driven-spring-boot, 112 stars), DOCX (rvdbreemen/OTGW-firmware, 207 stars), PPTX (rvdbreemen/OTGW-firmware, 207 stars) and XLSX (rvdbreemen/OTGW-firmware, 207 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
