review

Run a Gemini-backed review through the shared plugin runtime.

Raw slash-command arguments: $ARGUMENTS

Core constraint:

• This command is review-only.
• Do not fix issues, apply patches, or suggest that you are about to make changes.
• Your only job is to run the review and return Gemini's output verbatim to the user.

Execution mode rules:

• If the raw arguments include both --background and --stream, stop and tell the user to choose one.
• If the raw arguments include --stream, do not ask. Run the review in the foreground.
• If the raw arguments include --wait, do not ask. Run the review in the foreground.
• If the raw arguments include --background, do not ask. Run the review in a Claude background task.
• Otherwise, estimate the review size before asking:
  • For working-tree review, start with git status --short --untracked-files=all.
  • For working-tree review, also inspect both git diff --shortstat --cached and git diff --shortstat.
  • For base-branch review, use git diff --shortstat <base>...HEAD.
  • Treat untracked files or directories as reviewable work even when git diff --shortstat is empty.
  • Only conclude there is nothing to review when the relevant working-tree status is empty or the explicit branch diff is empty.
  • Recommend waiting only when the review is clearly tiny, roughly 1-2 files total and no sign of a broader directory-sized change.
  • In every other case, including unclear size, recommend background.
  • When in doubt, run the review instead of declaring that there is nothing to review.
• Then use AskUserQuestion exactly once with two options, putting the recommended option first and suffixing its label with (Recommended):
  • Wait for results
  • Run in background

Argument handling:

• Preserve the user's arguments exactly.
• Do not strip --wait or --background yourself.
• Preserve --stream exactly when the user passes it.
• Do not add extra review instructions or rewrite the user's intent.
• The companion script parses --wait and --background, but Claude Code's Bash(..., run_in_background: true) is what actually detaches the run.
• --stream forces foreground execution and conflicts with --background.
• In stream mode, the review prints raw Gemini text incrementally instead of waiting for the final formatted render.
• /gemini:review is native-review only. It does not support staged-only review, unstaged-only review, or extra focus text.
• If the user needs custom review instructions or more adversarial framing, they should use /gemini:adversarial-review.

Foreground flow:

• Use direct command execution syntax, not Bash, so foreground --stream output is not buffered by the tool layer.

• Run: !node "${CLAUDE_PLUGIN_ROOT}/scripts/gemini-companion.mjs" review "$ARGUMENTS"

• Return the command stdout verbatim, exactly as-is.

• Do not paraphrase, summarize, or add commentary before or after it.

• Do not fix any issues mentioned in the review output.

Background flow:

• Launch the review with Bash in the background:

Bash({
  command: `node "${CLAUDE_PLUGIN_ROOT}/scripts/gemini-companion.mjs" review "$ARGUMENTS"`,
  description: "Gemini review",
  run_in_background: true,
});

• Do not call BashOutput or wait for completion in this turn.
• After launching the command, tell the user: "Gemini review started in the background. Check /gemini:status for progress."
