  "how": {
    "incantation": "When you need to split a commit, run `git history split <commit>` and interactively choose hunks for a new parent commit; Git prompts for both commit messages. For rewriting a commit message, run `git history reword <commit>`.",
    "examples": [
      "git history split <commit>",
      "git history split <commit> [--dry-run] [--update-refs=(branches|head)] [--] [<pathspec>…]",
      "git history reword <commit> [--dry-run] [--update-refs=(branches|head)]"
    ],
    "gotchas": [
      "Version: 2.54.0",
      "Availability: experimental",
      "<commit> (required): Commit to split or reword.",
      "--dry-run: Print reference updates without updating references; necessary new objects are still written.",
      "--update-refs=(branches|head): `branches` updates descendant local branches; `head` updates only the current HEAD reference. These values are mutually exclusive. Defaults to `branches`.",
      "--: Separates options from pathspec arguments.",
      "<pathspec>…: Limits which changes may be split; nonmatching files remain in the original commit.",
      "Prerequisite: Use Git 2.54.0 or later for the documented command. `git history` is experimental; its behavior may change.",
      "Prerequisite: The command does not support histories containing merges or operations that can result in merge conflicts.",
      "Prerequisite: For `split`, selecting all hunks or no hunks is invalid because one resulting commit would be empty."
