Schema Mutation provenance

This file is generated from the benchmark definition.

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.
