# Gemini Literature Search

Search query: $ARGUMENTS

## Role & Positioning

This skill uses Gemini as a **broad literature discovery** source:

| Skill | Source | Best for |
|-------|--------|----------|
| `/arxiv` | arXiv API | Latest preprints, cutting-edge unrefereed work |
| `/semantic-scholar` | Semantic Scholar API | Published venue papers (IEEE, ACM, Springer) with citation counts |
| `/deepxiv` | DeepXiv CLI | Layered reading: search, brief, section map, section reads |
| `/exa-search` | Exa API | Broad web search: blogs, docs, news, companies, research papers |
| `/gemini-search` | Gemini MCP / CLI | **AI-powered broad literature discovery** — searches across multiple angles, aliases, and sub-problems |

Use Gemini when you want AI-driven discovery that goes beyond keyword matching — Gemini decomposes topics into sub-problems, explores naming variants, and surfaces papers that traditional API searches may miss.

## Constants

- **MAX_RESULTS = 15** — Target number of papers Gemini should find.
- **MIN_YEAR = 2022** — Default minimum publication year. Override with `— year: 2020-`.
- **DEFAULT_MODEL = auto-gemini-3** — Auto-routes within the Gemini 3 family (Pro / Flash) by server-side capacity. Required by `mcp__gemini-cli__ask-gemini` and `gemini-cli` v0.40+; explicit `gemini-3-pro-preview` is **silently downgraded to `gemini-2.5-pro`** on OAuth-personal / Google One AI Pro accounts when capacity is exhausted. Override with `— model: gemini-3-flash-preview` (Gemini 3 Flash explicit, faster, higher quota), or `— model: gemini-2.5-pro` / `gemini-2.5-flash` (legacy, only for users on older `gemini-cli` < v0.40). The MCP tool accepts all of these verbatim.

> Overrides (append to arguments):
> - `/gemini-search "topic" — max: 20` — request up to 20 papers
> - `/gemini-search "topic" — year: 2020-` — papers from 2020 onward
> - `/gemini-search "topic" — code-only` — only papers with open-source code
> - `/gemini-search "topic" — venues: NeurIPS,ICML,ICLR` — focus on specific venues
> - `/gemini-search "topic" — model: gemini-3-flash-preview` — Gemini 3 Flash (faster, higher quota, less capable than Pro)
> - `/gemini-search "topic" — model: auto-gemini-3` — auto-routes within the Gemini 3 family by load
> - `/gemini-search "topic" — model: gemini-2.5-pro` — legacy (only if your `gemini-cli` < v0.40)

## Environment & Setup

### Prerequisites

1. **Node.js** v16.0.0+
2. **Google Gemini CLI** — installed and authenticated
   ```bash
   npm install -g @google/gemini-cli
   gemini auth
   ```
3. **gemini-mcp-tool** — MCP bridge for Claude Code ([jamubc/gemini-mcp-tool](https://github.com/jamubc/gemini-mcp-tool))
   ```bash
   npm install -g gemini-mcp-tool
   ```

### MCP Configuration

In `~/.claude.json` (or `%APPDATA%\Claude\claude_desktop_config.json` for Claude Desktop), add:

```json
{
  "mcpServers": {
    "gemini-cli": {
      "command": "gemini-mcp"
    }
  }
}
```

Alternative via `npx` (auto-install):
```json
{
  "mcpServers": {
    "gemini-cli": {
      "command": "npx",
      "args": ["-y", "gemini-mcp-tool"]
    }
  }
}
```

Or one-line setup:
```bash
claude mcp add gemini-cli -- npx -y gemini-mcp-tool
```

### Authentication

Gemini CLI uses your Google account or an API key. Reuse an existing Google account login, or set an API key in the same shell **before starting Claude Code** so the MCP process inherits it:

```bash
export GEMINI_API_KEY='your-key-here'
claude
```

A separate tool-shell `export` does not update an already running host or MCP process. If you keep credentials in an environment file, load it explicitly before starting the host rather than relying on automatic `.env` loading.

- Free key from [Google AI Studio](https://aistudio.google.com/apikey)
- Flash model (`gemini-2.5-flash`) has a generous free tier (500 req/min)

### Available MCP Tools

| Tool | Parameters | Description |
|------|-----------|-------------|
| `mcp__gemini-cli__ask-gemini` | `prompt` (required), `model` (optional), `sandbox` (optional) | Ask Gemini for analysis or research; supports `@file` syntax |
| `mcp__gemini-cli__sandbox-test` | `prompt` (required), `model` (optional) | Safe code execution in sandbox |
| `mcp__gemini-cli__ping` | — | Connection test |
| `mcp__gemini-cli__help` | — | Show Gemini CLI help |

### Verify Setup

```bash
gemini --version
```

## Workflow

### Step 1: Parse Arguments

Parse `$ARGUMENTS` for:
- **query**: The research topic (required)
- **max**: Override MAX_RESULTS
- **year**: Minimum publication year (e.g., `2020-`)
- **code-only**: Only include papers with open-source code
- **venues**: Comma-separated venue filter
- **model**: Override DEFAULT_MODEL
