In plain words
What is it for?
Use it to review all code, recent files, or performance concerns in Forge, Fabric, NeoForge, Paper, and related projects.
Why use it?
Minecraft APIs change between versions, so code that worked for one version can fail or behave incorrectly in another.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

mc-review scanned grade A with 1 finding 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 2mo 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.

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Add this to `~/.claude/settings.json` (or the project `.claude/settings.json`) to run a quick review after each Java/JSON edit:

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

mc-review

Statically review mod/plugin code, surface potential issues, and give concrete fixes.

How to trigger

Manual:

  • /mc-review — review all code in the current project
  • /mc-review --quick — only recently modified files
  • /mc-review --perf — performance checks only

Automatic (Hook): configure a PostToolUse hook so that when Write/Edit touches .java or .json files, a quick review runs and reports findings. See "Hook setup" below.

Review dimensions

4.0 Version adaptation (highest priority)

  • Is the target version <= 1.20.4 or >= 1.20.5? Does the API usage match?
  • Does >= 1.20.5 code still use removed old-NBT APIs like stack.getTag() / stack.getOrCreateTag()?
  • Is the Data Component registration done correctly?
  • >= 1.21.4: does custom_model_data use the new list structure instead of a single int?
  • >= 1.21.4: any misuse of the removed ItemColors / BuiltinItemRenderer?
  • >= 1.21.4: is Pick Block moved to the server-side API?
  • Are enchantment / damage / durability handled via Data Components rather than raw NBT?
  • Cross-version: if multiple versions are supported, are there version branches?

4.1 Correctness

  • API calls match the current MC version
  • DeferredRegister correctly registered to the mod event bus
  • Side-only code annotated with @OnlyIn(Dist.CLIENT) where needed
  • Network packets sent on the correct logical side
  • Metadata completeness: plugin.yml / fabric.mod.json / mods.toml
  • Registered types are correct (e.g. a Block has a matching BlockItem)
  • Mixin injection points are safe (FINAL, target method signatures)

4.2 Performance

  • Expensive work in tick() (heavy loops, I/O, per-tick allocation)
  • Capability implements INBTSerializable correctly
  • Per-frame allocation in renderers
  • Data generation accidentally on the production path
  • Map<BlockPos, *> performance over large iterations
  • Excessive synchronous network calls

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.
