origin remote is unavailable for this repository.

Error message

origin remote is unavailable for this repository.

What it means

ensurePrRemoteWithRepo, for same-repository PRs, reuses the `origin` remote URL as the clone/worktree source. If `repository.remoteUrl("origin")` returns null — no origin remote is configured — it throws this ToolError because there is no URL to fetch the PR from.

Solutions

1. Add the origin remote: `git remote add origin <https or ssh GitHub URL>` and retry.
2. Point the checkout at the correct existing remote by configuring/renaming it to origin (`git remote rename upstream origin`).
3. If it's a cross-repo PR, ensure headRepository metadata is correct so the fork URL path is taken instead of the origin path.

Example fix

# before
$ git remote -v   # (empty or only 'upstream')
# after
$ git remote add origin https://github.com/owner/repo.git
$ git fetch origin

import { $ } from "bun";
const remote = await $`git remote get-url origin`.cwd(cwd).quiet().nothrow();
if (remote.exitCode !== 0) {
  throw new Error("origin remote missing; add it before PR checkout");
}

try {
  await checkoutPullRequest({ cwd, pr });
} catch (err) {
  if (err instanceof ToolError && err.message.includes("origin remote is unavailable")) {
    await $`git remote add origin https://github.com/owner/repo.git`.cwd(cwd);
    // retry checkout
  } else throw err;
}

When it happens

Trigger: checkoutPullRequest on a PR whose head is in the same repository, in a repo that has no `origin` remote (cloned from a local path, added as a secondary remote with another name, or initialized locally).

Common situations: Repo initialized locally (git init) then PR opened after pushing via a differently named remote; remotes renamed so origin is missing; sparse CI checkouts that strip remotes.
