What this skill does


# Fastest Browser Use

A Rust-based browser automation engine that provides a lightweight binary driving Chrome directly via CDP. It is optimized for token-efficient DOM extraction, robust session management, and speed.

![Terminal Demo](https://placehold.co/800x400/1e1e1e/ffffff?text=Terminal+Demo+Coming+Soon)

## 🧪 Recipes for Agents

### 1. Bypass "Bot Detection" via Human Emulation
Simulate mouse jitter and random delays to scrape protected sites.

```bash
fast-browser-use navigate --url "https://protected-site.com" \
  --human-emulation \
  --wait-for-selector "#content"
```

### 2. The "Deep Freeze" Snapshot
Capture the entire DOM state *and* computed styles for perfect reconstruction later.

```bash
fast-browser-use snapshot --include-styles --output state.json
```

### 3. Login & Cookie Heist
Log in manually once, then steal the session for headless automation.

**Step 1: Open non-headless for manual login**
```bash
fast-browser-use login --url "https://github.com/login" --save-session ./auth.json
```

**Step 2: Reuse session later**
```bash
fast-browser-use navigate --url "https://github.com/dashboard" --load-session ./auth.json
```

### 4. 🚜 Infinite Scroll Harvester
**Extract fresh data from infinite-scroll pages** — perfect for harvesting the latest posts, news, or social feeds.

```bash
# Harvest headlines from Hacker News (scrolls 3x, waits 800ms between)
fast-browser-use harvest \
  --url "https://news.ycombinator.com" \
  --selector ".titleline a" \
  --scrolls 3 \
  --delay 800 \
  --output headlines.json
```

**Real output** (59 unique items in ~6 seconds):
```json
[
  "Genode OS is a tool kit for building highly secure special-purpose OS",
  "Mobile carriers can get your GPS location",
  "Students using \"humanizer\" programs to beat accusations of cheating with AI",
  "Finland to end \"uncontrolled human experiment\" with ban on youth social media",
  ...
]
```

Works on any infinite scroll page: Reddit, Twitter, LinkedIn feeds, search results, etc.

### 5. 📸 Quick Screenshot
Capture any page as PNG:

```bash
fast-browser-use screenshot \
  --url "https://example.com" \
  --output page.png \
  --full-page  # Optional: capture entire scrollable page
```

## ⚡ Performance Comparison

| Feature | Fast Browser Use (Rust) | Puppeteer (Node) | Selenium (Java) |
| :--- | :--- | :--- | :--- |
| **Startup Time** | **< 50ms** | ~800ms | ~2500ms |
| **Memory Footprint** | **15 MB** | 100 MB+ | 200 MB+ |
| **DOM Extract** | **Zero-Copy** | JSON Serialize | Slow Bridge |

## Capabilities & Tools

### Vision & Extraction
- **vision_map**: Returns a screenshot overlay with numbered bounding boxes for all interactive elements.
- **snapshot**: Capture the raw HTML snapshot (YAML/Markdown optimized for AI).
- **screenshot**: Capture a visual image of the page.
- **extract**: Get structured data from the DOM.
- **markdown**: Convert the current page content to Markdown.

### Navigation & Lifecycle
- **navigate**: Visit a specific URL.
- **go_back** / **go_forward**: Traverse browser history.
- **wait**: Pause execution or wait for specific conditions.
- **new_tab**: Open a new browser tab.
- **switch_tab**: Switch focus to a specific tab.
- **close_tab**: Close the current or specified tab.
- **tab_list**: List all open tabs.
- **close**: Terminate the browser session.

### Interaction
- **click**: Click elements via CSS selectors or DOM indices.
- **input**: Type text into fields.
- **press_key**: Send specific keyboard events.
- **hover**: Hover over elements.
- **scroll**: Scroll the viewport.
- **select**: Choose options in dropdowns.

### State & Debugging
- **cookies**: Manage session cookies (get/set).
- **local_storage**: Manage local storage data.
- **debug**: Access console logs and debug information.

## Usage

This skill is specialized for complex web interactions that require maintaining state (like being logged in), handling dynamic JavaScript content, or managing multiple pages simultaneously. It offers higher performance and control compared to standard fetch-based tools.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

Backend & APIsscripts

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
