| # ForgeBench v1 — independent benchmark for Minecraft-modding LLMs |
|
|
| Contamination-free evaluation benchmark for models fine-tuned on the |
| `ComerX/forge-neoforge-sft-*` dataset family. Targets **NeoForge 1.21.1** and |
| **Forge 1.20.1** (Mojang mappings). 100 tasks, 5 modules × 20. |
|
|
| ## Data files (what the Dataset Viewer loads) |
|
|
| | Config | Split | File | Rows | |
| |---|---|---|---| |
| | `forgebench_full` | `tasks` | `data/forgebench_full.jsonl` | 100 | |
| | `schema_example` | `examples` | `data/schema_example.jsonl` | 3 | |
|
|
| Both files are UTF-8 JSONL, one task object per line — loadable with |
| `load_dataset("ComerX/forgebench-v1", "forgebench_full")` or line-by-line with |
| `json.loads`. Everything else in the repo (`harness/`, `template/`, reports) is |
| tooling, not data. |
|
|
| ## Task schema (strict) |
|
|
| ```json |
| { |
| "task_id": "MIXIN_014", |
| "module": "api | mixin | migration | debug | build", |
| "instruction": "prompt given to the evaluated LLM", |
| "context": "vanilla snippet / crash log / legacy code (may be empty)", |
| "golden_reference": "reference answer", |
| "eval_criteria": { |
| "must_compile": true, |
| "required_annotations": ["@Inject"], |
| "forbidden_apis": ["net.minecraft.util.text"], |
| "gametest_required": false |
| } |
| } |
| ``` |
|
|
| `context` is `""` for tasks that need no reference material (e.g. pure API |
| registration drills); it contains vanilla/legacy code or FML log excerpts for |
| `mixin`, `migration` and `debug` tasks. |
|
|
| ## Modules |
|
|
| | Module | Count | Task type | Grading | |
| |---|---|---|---| |
| | `api` (API & registration) | 20 | instruction→code | compile + AST gate | |
| | `mixin` (Mojmap targets) | 20 | FIM / translation | compile + AST gate | |
| | `migration` (1.20.1→1.21.1) | 20 | refactoring | compile + AST gate (legacy APIs forbidden) | |
| | `debug` (FML crash logs) | 20 | log analysis → JSON | judge + JSON-shape gate | |
| | `build` (Gradle KTS / mods.toml) | 20 | config generation | judge + required-token gate | |
|
|
| ## Layout |
|
|
| ``` |
| data/ |
| forgebench_full.jsonl # 100 tasks (single JSONL, one task per line) |
| schema_example.jsonl # 3 complete examples (Mixin / Migration / Crash log) |
| harness/ |
| Dockerfile # sandbox image: JDK 21 + Gradle 8.9 + prebuilt MDK template |
| sandbox_runner.py # injects answer into MDK -> ./gradlew build -x test -> Pass@1 |
| ast_eval.py # javalang AST gate: syntax, forbidden APIs, hallucinated |
| # imports, required annotations, version-mix penalties |
| gametest_runner.py # GameTest template generation + headless run |
| judge_prompt.txt # strict LLM-as-a-judge rubric for debug/build tasks |
| run_benchmark.py # driver: aggregates sandbox + AST + judge into a report |
| requirements.txt |
| template/ # minimal NeoForge 1.21.1 MDK (NeoGradle 7 userdev) |
| VERIFICATION.md # benchmark self-verification results (19/19) |
| verification_result.json # machine-readable check log |
| SHA256SUMS.txt # integrity manifest (sha256 of every repo file) |
| ``` |
|
|
| ## Running |
|
|
| ```bash |
| # 0. build the sandbox image (once) |
| docker build -t forgebench-sandbox:1.21.1 . |
| |
| # 1. produce answers.jsonl: {"task_id": ..., "answer": ...} per row |
| |
| # 2a. offline static gate only |
| python3 harness/run_benchmark.py --data data/forgebench_full.jsonl \ |
| --answers answers.jsonl --skip-compile --out report.json |
| |
| # 2b. full compile evaluation (inside Docker) |
| python3 harness/run_benchmark.py --data data/forgebench_full.jsonl \ |
| --answers answers.jsonl --out report.json |
| |
| # 3. judge-graded tasks (debug/build): run your judge LLM with harness/judge_prompt.txt |
| # and pass scores via --scores '{"DEBUG_004": {"score": 9, "verdict": "pass"}, ...}' |
| ``` |
|
|
| ## Contamination status |
|
|
| Golden references and instructions were screened against the public SFT corpus |
| (`ComerX/forge-neoforge-sft-v2.1.0-rc2` + `-rc1`, sampled shards): **0 hits** |
| (normalized 300-char prefix containment). The benchmark tasks are synthetic |
| examples, not derived from any corpus repository. |
|
|
| ## Integrity |
|
|
| - Frozen artifact: `SHA256SUMS.txt` (sha256 of every file in this repo). |
| - The benchmark is immutable once published; changes require a new version tag. |
|

| ## License |
