| ## Seeded schema-mutation task generator | |
| - Kind: `synthetic` | |
| - URL: https://github.com/pooriaarab/benchmark-schema-mutation/blob/main/scripts/gen-tasks.mjs | |
| - Licence: `MIT` | |
| - Retrieved: 2026-10-15T00:00:00.000Z | |
| - How to get it: Run `node scripts/gen-tasks.mjs` for the public split (seed 20261015) or `node scripts/gen-tasks.mjs --seed <n> --split hidden` for a held-out split. | |
| - Contamination notes: All 60 public tasks are synthetic mutations of 12 hand-authored base tool schemas. The hidden split uses a different seed, which selects different values, mutation variants, field names and enum targets, and is never committed, so public tasks may enter training data without leaking final evaluation items. | |
| - Refresh: Change the seed, rerun the generator, and review the JSONL diff. Rotate mutation parameters quarterly. | |
