Cannot determine repository name from dataset source: ${sour

Error message

Cannot determine repository name from dataset source: ${source}

What it means

repositoryName derives a cache directory name from a dataset source by taking the last path segment (stripping trailing slashes and .git). If the source reduces to an empty basename (e.g. source is '/' or ends with '/.git' collapsing to empty), the cache location cannot be determined, so it throws.

Solutions

1. Pass a full git URL including the repository name, e.g. https://github.com/owner/repo.git
2. Fix empty/unexpanded template variables in the script constructing the source
3. Verify the source string has a non-empty last path segment

Example fix

// before
resolveDataset("https://github.com/laude-institute/")
// after
resolveDataset("https://github.com/laude-institute/terminal-bench.git")

function hasBasename(source: string): boolean {
  const trimmed = source.replace(/\/+$/, "");
  return trimmed.slice(trimmed.lastIndexOf("/") + 1).replace(/\.git$/, "").length > 0;
}
if (!hasBasename(source)) throw new Error(`Dataset source needs a repo name: ${source}`);

When it happens

Trigger: checkoutDir (via resolveDataset) receives a git URL whose post-processing basename is empty — e.g. source 'https://host/' or a path of only slashes.

Common situations: Config with a truncated URL (host only, no repo path); template variable left empty in a script building the dataset URL.
