  Enhanced web search and real-time content retrieval via Grok API with forced tool routing. Use when: (1) Web search / information retrieval / fact-checking, (2) Webpage content extraction / URL parsing, (3) Breaking knowledge cutoff limits for current information, (4) Real-time news and technical documentation, (5) Multi-source information aggregation. Triggers: "search for", "find information about", "latest news", "current", "fetch webpage", "get content from URL". IMPORTANT: This skill REPLACES built-in WebSearch/WebFetch with Grok Search tools.

# Grok Search

Enhanced web search via Grok API. Standalone CLI only (no MCP dependency).

## Implementation Layout

- `scripts/groksearch_cli.py` - CLI entrypoint and compatibility facade
- `scripts/groksearch/` - internal modules for config, HTTP retry, Grok provider, Tavily calls, formatting, and commands

## Execution Methods

Run `scripts/groksearch_cli.py` via Bash:

```bash
# Prerequisites: pip install httpx tenacity
# Environment: GROK_API_URL, GROK_API_KEY (required); TAVILY_API_KEY (optional)

# Web search (Grok only)
python scripts/groksearch_cli.py web_search --query "search terms" [--platform "GitHub"] [--min-results 3] [--max-results 10]

# Web search with Tavily extra sources (parallel + URL-deduplicated merge)
python scripts/groksearch_cli.py web_search --query "..." --extra-sources 5

# Fetch webpage (default: Grok)
python scripts/groksearch_cli.py web_fetch --url "https://..." [--out file.md]

# Fetch via Tavily extract endpoint
python scripts/groksearch_cli.py web_fetch --url "https://..." --via tavily

# Map a website's structure (Tavily)
python scripts/groksearch_cli.py web_map --url "https://docs.example.com" [--instructions "API only"] [--max-depth 2] [--max-breadth 20] [--limit 50] [--timeout 150]

# Check config
python scripts/groksearch_cli.py get_config_info [--no-test]

# Switch model
python scripts/groksearch_cli.py switch_model --model "grok-2-latest"

# Toggle built-in tools
python scripts/groksearch_cli.py toggle_builtin_tools --action on|off|status [--root /path/to/project]
```

## Tool Routing Policy

### Forced Replacement Rules

| Scenario | Disabled | Force Use |
|----------|----------|-----------|
| Web Search | `WebSearch` | CLI `web_search` |
| Web Fetch | `WebFetch` | CLI `web_fetch` |

### Tool Capability Matrix

| Tool | Parameters | Output |
|------|------------|--------|
| `web_search` | `query`(required), `platform`/`min_results`/`max_results`(optional), `extra_sources`(int, 0=disabled) | `[{title,url,description,provider?}]` |
| `web_fetch` | `url`(required), `out`(optional), `via`(grok\|tavily, default grok) | Structured Markdown |
| `web_map` | `url`(required), `instructions`/`max_depth`/`max_breadth`/`limit`/`timeout`(optional) | `{base_url,results,response_time}` JSON |
| `get_config_info` | `no_test`(optional) | `{api_url,status,connection_test,tavily_*}` |
| `switch_model` | `model`(required) | `{previous_model,current_model}` |
| `toggle_builtin_tools` | `action`(on/off/status), `root`(optional) | `{blocked,deny_list}` |

## Search Workflow

### Phase 1: Query Construction
- **Intent Recognition**: Broad search → `web_search` | Deep retrieval → `web_fetch`
- **Parameter Optimization**: Set `platform` for specific sources, adjust result counts

### Phase 2: Search Execution
1. Start with `web_search` for structured summaries
2. Use `web_fetch` on key URLs if summaries insufficient
3. Retry with adjusted query if first round unsatisfactory

### Phase 3: URL Verification & Hallucination Guard (MANDATORY)

**Background**: Grok API calls without explicit web-search activation return results from parametric memory, which frequently fabricates URLs (observed 25% liveness rate in testing). All Grok-returned URLs MUST be verified before citation.

**Verification Protocol**:
1. **URL Liveness Check**: Issue HEAD/GET request to each Grok-returned URL; non-2xx status = unreliable
2. **Tavily Fallback Triggers** (invoke `web_search` with `--extra-sources N` when ANY apply):
   - URL liveness rate < 50% in Grok results
   - Query contains version numbers, release dates, API signatures, or "latest"/"recent" temporal markers (high hallucination surface)
   - Multiple Grok runs return contradictory URLs for the same factual claim
   - Grok result descriptions contain specifics (dates/versions/methods) that cannot be confirmed from live URLs
3. **Tavily Grounding**: When triggered, re-run the same query with `--extra-sources 5-10` to obtain Tavily search results; prioritize these over failed Grok URLs
4. **Content Extraction**: For critical factual claims, use `web_fetch --via tavily` on verified URLs to extract authoritative source text

**Citation Discipline**:
- **ONLY** verified-live URLs may appear in final output
- Fabricated Grok URLs must be dropped entirely (do not present them with a disclaimer; omit them)
- When Tavily sources replace Grok sources, cite Tavily URLs and mark provider as `tavily`
- For time-sensitive queries with no live sources, state "Unable to verify current information" rather than citing dead links

### Phase 4: Result Synthesis
1. Cross-reference multiple sources
2. **Must annotate source and date** for time-sensitive info
3. **Must include source URLs**: `Title [<sup>1</sup>](URL)`

## Error Handling

| Error | Recovery |
|-------|----------|
| Connection Failure | Run `get_config_info`, verify API URL/Key |
| No Results | Broaden search terms |
| Fetch Timeout | Try alternative sources |

## Anti-Patterns

| Prohibited | Correct |
|------------|---------|
| No source citation | Include `Source [<sup>1</sup>](URL)` |
| Give up after one failure | Retry at least once |
| Use built-in WebSearch/WebFetch | Use GrokSearch tools/CLI |
