two TB Science

This repository contains one selected Terminal-Bench-Science local-reference sample: 09-reaction-thermochemistry.

Why this sample was selected

The reaction-thermochemistry task was selected from two candidates because it is compact, has a frozen scientific source chain, includes reproducible task and verifier assets, and is easier to audit as a standalone example.

What the task evaluates

The task asks an agent to analyze ignition-delay measurements using pressure-specific USC Mech II kinetic mechanisms. It covers source-quality checks, baseline simulation, sensitivity analysis, reaction screening, calibration, cross-validation, and structured result generation.

Repository contents

• sample/09-reaction-thermochemistry/: complete task package, including the environment, input data, verifier, expected reference outputs, solution, and authoring evidence.
• SELECTION.json: selection decision and scope boundary.
• EVALUATION_SUMMARY.json: four-run local reference summary.
• LICENSE_NOTES.md: source, attribution, and redistribution notes.
• VALIDATION_REPORT.json: upload-package checks.
• MANIFEST.json and SHA256SUMS.txt: file inventory and integrity hashes.

Qualification boundary

This is a local reference sample, not official Terminal-Bench-Science qualification evidence. The four recorded Opus 5 runs completed without infrastructure errors and received scores of 0.0, 0.0, 0.0, 0.0. Those scores are local results under a public-network-derived task path; they should not be interpreted as official benchmark acceptance or definitive proof of scientific difficulty.

The NIST-origin software notice is retained inside the package. The USC Mech page makes the mechanism files available for download and provides citation instructions, but this package does not claim a separate open-data license for those third-party mechanism files. The repository is publicly visible at the repository owner's direction while a final redistribution-rights review remains pending; downstream users should independently verify the applicable terms before redistribution.

Reproducibility

Start with sample/09-reaction-thermochemistry/instruction.md and task.toml. The environment and verifier definitions are under environment/ and tests/. Compare local files against SHA256SUMS.txt before use.
