## Original datasource

- CrossCodeEval (C# split) — https://arxiv.org/abs/2310.11248

## Domains

Software Engineering

- **Software Engineering:** Every sampled task is cross-file code completion in a real C# repository (Unity mods, ASP.NET extensions, WPF samples): the agent must produce the next statement of a cut-off declaration, consistent with types, attributes, and method signatures defined in sibling files supplied under /setup_files/context.

## Agent capabilities

Exploration, Specification Adherence

- **Exploration:** Intended practice: the correct continuation (e.g. 'LogLevel> LootingLogLevels;', 'StyleSheetName => nameof(SceneSelectorWindow);', 'LogdashboardAccountAuthorizeFilter filter, ...') depends on identifiers declared only in the retrieved cross-file excerpts, so the agent is expected to read those files before answering. No trajectories were supplied, so observed behavior cannot be confirmed.
- **Specification Adherence:** Intended practice: the verifier (a port of the official cceval metric) truncates the prediction to its first statement and requires an exact line-by-line match with the reference. The instruction further requires writing only the short fragment to /app/solution.txt via a quote-safe helper, with no re-emitted prefix, usings, code fences, or labels. Output drift of any kind fails the task. Not observed in trajectories since none were supplied.

## Expected benchmark transfer

These are hypotheses, not measured training gains.

The tasks are single-statement C# completions scored by exact string match against a fixed reference, with no compilation or execution. The suite's code benchmarks are Python-centric and execution-verified (HumanEval+, MBPP+, DS-1000, CRUXEval, SWE-bench Verified), and the terminal benchmarks (Terminal-Bench 2.0, OpenThoughts-TBLite) require multi-step shell work, whereas these tasks reduce to reading a few context files and writing one line. The language, output format, and verification signal are too far from any suite benchmark to reasonably expect a score increase.
