name: gemini-cli description: Use the Google Gemini CLI to get a second opinion on code, architecture, and UI/UX work. Trigger when a user asks to consult Gemini, wants an external critique, or requests UI feedback, design alternatives, or code review via the Gemini CLI.

Gemini CLI

Overview

Use the Gemini CLI as a fast second-opinion engine for UI critique and code review. Keep prompts focused, include only the relevant context, and validate suggestions before applying.

Quick start

1. Confirm the CLI binary and input mode:

   • Use gemini as the default command name.
   • Run gemini --help to identify supported flags and input modes.
   • Prefer the positional prompt for one-shot runs (the --prompt flag is deprecated).
   • If stdin is supported, prefer piping a structured prompt or a file.

2. Run with full context once the CLI invocation is working; avoid test prompts to save tokens.

   • Prefer --output-format text for readability or --output-format json for structured parsing.

Workflow

1. Classify the request:

   • UI/UX critique: layout, hierarchy, visual design, accessibility, interaction flow.
   • UI alternative generation: new layout concepts or copy variations.
   • Code second opinion: review logic, edge cases, performance, correctness.
   • Architecture check: tradeoffs, risks, suggested alternatives.

2. Gather context (keep it minimal):

   • Goal, constraints, target platform, and success criteria.
   • Relevant code, diffs, or snippets only (avoid entire repos).
   • Any non-negotiables (design system, performance limits, deadlines).

3. Run the CLI with a structured prompt.

4. Validate the response:

   • Check for incorrect assumptions or hallucinated APIs.
   • Cross-check suggestions against project constraints.
   • Apply only improvements that you can justify.

Prompt patterns

UI critique

Use when asking for layout and visual feedback.

CopyYou are a senior product designer.
Critique this UI for hierarchy, clarity, and accessibility.
Return: (1) top 3 issues, (2) quick wins, (3) risky changes.

Context:
- Platform: <web | iOS | Android | desktop>
- Audience: <persona>
- Constraints: <design system, brand, perf>

UI description or markup:
<brief description, screenshot notes, or key UI code>

UI alternatives

Use when you want multiple layout or copy options.

CopyYou are a UX lead.
Propose 3 alternative layouts with pros/cons and when to use each.

Context:
- Goal: <what must improve>
- Constraints: <grid, components, tokens>

Current UI summary:
<short summary>

Code second opinion

Use for review and risk spotting.

CopyYou are a staff engineer.
Review the code below for correctness, edge cases, and maintainability.
Return: (1) risks, (2) suggested fixes, (3) quick refactors.

Context:
- Language/stack: <...>
- Constraints: <perf, security, compatibility>

Code:
<snippet or diff>

Architecture tradeoffs

Use for system design or refactor choices.

CopyYou are a pragmatic architect.
Evaluate these options and recommend one. Include tradeoffs and failure modes.

Context:
- Goal: <...>
- Constraints: <cost, latency, team skills>

Options:
1) <option A>
2) <option B>

Notes

• Avoid sending secrets or proprietary data unless explicitly approved.
• Prefer short, specific prompts over broad requests.
• If the CLI supports file inputs, prefer file paths over large inline text.
