Current git repository is unavailable.

Error message

Current git repository is unavailable.

What it means

requireGitRepoRoot resolves the enclosing git repository root via vcs.git(cwd)?.info().repoRoot and throws this ToolError when null — i.e. the working directory is not inside a git repository (or the vcs wrapper failed). PR checkout needs a repo root to anchor worktree paths.

Solutions

1. Run the PR checkout from inside a git repository.
2. Run `git init` if the project should be a repo, or `git clone` it first.
3. Confirm `git rev-parse --show-toplevel` succeeds in the target cwd.

Example fix

// before
await checkoutPullRequest({ cwd: "/tmp/not-a-repo", pr: 12 });
// after
cwd = "/home/user/project"; // a git repo
await checkoutPullRequest({ cwd, pr: 12 });

import { $ } from "bun";
const root = await $`git rev-parse --show-toplevel`.cwd(cwd).quiet().nothrow();
if (root.exitCode !== 0) {
  throw new Error(`${cwd} is not a git repository`);
}

try {
  const repoRoot = await repoRoot(cwd);
} catch (err) {
  if (err instanceof ToolError && err.message.includes("git repository is unavailable")) {
    // clone/init the repo or relocate cwd before retrying
  } else throw err;
}

When it happens

Trigger: Calling repoRoot() (backed by requireGitRepoRoot) from a directory outside any git work tree, or where git info cannot report a repoRoot (bare path, git unavailable, aborted signal).

Common situations: Agent launched in a temp/home directory; project not yet git-initialized; git binary missing or broken so info() fails silently to null.
