    "incantation": "When appending pull requests to an existing stack, run `gh stack link <stack-number> <pr-number-or-url> <branch-name>`; the stack number selects the target, and the remaining arguments are ordered bottom to top.",

    "gotchas": [
      "Version: v0.0.8",
      "<stack-number> (required): Target existing stack number; the task’s release example uses it as the first argument.",
      "<branch-or-pr> (required): One or more branch names, PR numbers, or PR URLs, in stack order from bottom to top. Branches are pushed automatically; mismatched PR base branches are corrected.",
      "Prerequisite: Install GitHub CLI 2.0+ and Git 2.36+; install the extension with `gh extension install github/gh-stack`. Authenticate with `gh auth login` if needed.",
      "The operation appends PRs to the top of an existing stack.",
      "PRs that belong to a different stack are rejected."

  "why_it_matters": "When adding pull requests to the top of an existing stack, link them by stack number without restating the stack's existing pull requests.",
  "before": "Restate every PR already in the stack along with the PRs to append.",
