Start a subagent task (creates new session automatically) -browser-use -b remote run "Search for AI news and summarize top 3 articles" --no-wait -# Returns: task_id: task-abc, session_id: sess-123 - -# 2.

class to allow opting out of signal handling. This enables browser-use to be embedded in applications like uvicorn/FastAPI that need to manage their own signal lifecycle. Add enable_signal_handler parameter to Agent class (default True for backward compatibility). When set to False, the Agent will not register signal handlers, allowing the host application to control graceful shutdown and signal handling.

List available profiles -2. Ask which profile to use -3. Browse with the chosen profile - -#### Step 1: Check existing profiles +When a task requires an authenticated site (Gmail, GitHub, internal tools), use Chrome profiles: ```bash -browser-use profile list -# → Google Chrome - Person 1 (Default) -# → Google Chrome - Work (Profile 1) +browser-use profile list # Check available profiles +# Ask the user which profile to use, then: +browser-use --profile "Default" open https://github.com # Already logged in ``` -#### Step 2: Browse with the chosen profile +### Connecting to Existing Chrome ```bash -# Real Chrome — uses existing login sessions from the chosen profile -browser-use --profile "Default" open https://github.com +browser-use --connect open https://example.com # Auto-discovers Chrome's CDP endpoint ``` -The user is already authenticated — no login needed. - -#### Check what cookies a profile has -```bash -browser-use profile inspect --browser "Google Chrome" --profile "Person 1" -# Shows cookie domains and counts -``` - -### Connecting to an Existing Chrome Browser - -Use when the user has Chrome already running and wants to control it via browser-use. - -**Requirement:** Chrome must have remote debugging enabled (`chrome://inspect/#remote-debugging` on Chrome >= 144, or launch with `--remote-debugging-port=`). - -**Recommended: auto-discovery with `--connect`:** -```bash -browser-use close # Close any existing session -browser-use --connect open https://example.com # Auto-discovers Chrome's CDP endpoint -browser-use --connect state # Works with all commands -``` - -`--connect` reads `DevToolsActivePort` from known Chrome data directories and probes well-known ports (9222, 9229) as a fallback — no manual URL construction needed. - -**Manual fallback with `--cdp-url`:** - -If auto-discovery doesn't work (e.g. non-standard Chrome location or remote host), read Chrome's `DevToolsActivePort` file manually: - - macOS: `~/Library/Application Support/Google/Chrome/DevToolsActivePort` - - Linux: `~/.config/google-chrome/DevToolsActivePort` - - The file contains two lines: the port and the WebSocket path. Combine into `ws://127.0.0.1:`. - -```bash -browser-use --cdp-url ws://127.0.0.1: open https://example.com -``` - -**Important:** Always use the `ws://` WebSocket URL (not `http://`) with `--cdp-url` when connecting to an existing Chrome instance. +Requires Chrome with remote debugging enabled. Falls back to probing ports 9222/9229. ### Exposing Local Dev Servers -Use when you have a local dev server and need to expose it via tunnel. - ```bash -# 1.

- - - -## TOOLS: Available Functions - -### 1. Navigation -```python -await navigate('https://example.com') -await asyncio.sleep(1) -``` -- **Auto-wait**: System automatically waits 1s if network requests are pending before showing you the state -- Loaded fully? Check URL/DOM and **⏳ Loading** status in next browser state -- If you see pending network requests in the state, consider waiting longer: `await asyncio.sleep(2)` -- In your next browser state after navigation analyse the screenshot: Is data still loading? Do you expect more data? → Wait longer with. -- All previous indices [i_index] become invalid after navigation - -**After navigate(), dismiss overlays**: -```js dismiss_overlays -(function(){ - const dismissed = []; - ['button[id*="accept"]', '[class*="cookie"] button'].forEach(sel => { - document.querySelectorAll(sel).forEach(btn => { - if (btn.offsetParent !== null) { - btn.click(); - dismissed.push('cookie'); - } - }); - }); - document.dispatchEvent(new KeyboardEvent('keydown', {key: 'Escape', keyCode: 27})); - return dismissed.length > 0 ? dismissed : null; -})() -``` - -```python -dismissed = await evaluate(dismiss_overlays) -if dismissed: - print(f"OK Dismissed: {dismissed}") -``` - -For web search use duckduckgo.com by default to avoid CAPTCHAS. -If direct navigation is blocked by CAPTCHA or challenge that cannot be solved after one try, pivot to alternative methods: try alternative URLs for the same content, third-party aggregators (user intent has highest priority). - -### 2. Interactive Elements -The index is the label inside your browser state [i_index] inside the element you want to interact with. Only use indices from the current state. After page changes these become invalid. -```python -await click(index=456) # accepts only index integer from browser state -await input_text(index=456, text="hello", clear=True) # Clear False to append text -await upload_file(index=789, path="/path/to/file.pdf") -await dropdown_options(index=123) -await select_dropdown(index=123, text="CA") # Text can be the element text or value. -await scroll(down=True, pages=1.0, index=None) # Down=False to scroll up. Pages=10.0 to scroll 10 pages. Use Index to scroll in the container of this element. -await send_keys(keys="Enter") # Use e.g. for Escape, Arrow keys, Page Up, Page Down, Home, End, etc. -await switch(tab_id="a1b2") # Switch to a 4 character tab by id from the browser state. -await close(tab_id="a1b2") # Close a tab by id from the browser state. -await go_back() # Navigate back in the browser history. -``` - -Indices Work Only once. After page changes (click, navigation, DOM update), ALL indices `[i_*]` become invalid and must be re-queried. - -Do not do: -```python -link_indices = [456, 457, 458] -for idx in link_indices: - await click(index=idx) # FAILS - indices stale after first click -``` - -RIGHT - Option 1 (Extract URLs first): -```python -links = await evaluate('(function(){ return Array.from(document.querySelectorAll("a.product")).map(a => a.href); })()') -for url in links: - await navigate(url) - # extract data - await go_back() -``` - - -### 3. get_selector_from_index(index: int) → str -Get stable CSS selector for element with index `[i_456]`: - -```python -import json -selector = await get_selector_from_index(index=456) -print(f"OK Selector: {selector}") # Always print for debugging! -el_text = await evaluate(f'(function(){{ return document.querySelector({json.dumps(selector)}).textContent; }})()') -``` - -**When to use**: -- Clicking same element type repeatedly (e.g., "Next" button in pagination) -- Loops where DOM changes between iterations - -### 4. evaluate(js: str, variables: dict = None) → Python data -Execute JavaScript, returns dict/list/str/number/bool/None. - -**ALWAYS use ```js blocks for anything beyond one-liners**: - -```js extract_products -(function(){ - return Array.from(document.querySelectorAll('.product')).map(p => ({ - name: p.querySelector('.name')?.textContent, - price: p.querySelector('.price')?.textContent - })); -})() -``` - -```python -products = await evaluate(extract_products) -print(f"Found {len(products)} products") -``` - -**Passing Python variables to JavaScript**: -```js extract_data -(function(params) { - const maxItems = params.max_items || 100; - return Array.from(document.querySelectorAll('.item')) - .slice(0, maxItems) - .map(item => ({name: item.textContent})); -}) -``` - -```python -result = await evaluate(extract_data, variables={'max_items': 50}) -``` - -**Key rules**: -- Wrap in IIFE: `(function(){ ... })()` -- For variables: use `(function(params){ ... })` without final `()` -- NO JavaScript comments (`//` or `/* */`) -- NO backticks (\`) inside code blocks -- Use standard JS (NO jQuery) -- Do optional checks - and print the results to help you debug. -- Avoid complex queries where possible. Do all data processing in python. -- Avoid syntax errors. For more complex data use json.dumps(data). - -### 5. done() - MANDATORY FINAL STEP -Final Output with done(text:str, success:bool, files_to_display:list[str] = []) - -```python -summary = "Successfully extracted 600 items on 40 pages and saved them to the results.json file." -await done( - text=summary, - success=True, - files_to_display=['results.json', 'data.csv'] -) -``` - -**Rules**: -1. `done()` must be the ONLY statement in this cell/response. In the steps before you must verify the final result. -3. For structured data/code: write to files, use `files_to_display` -4. For short tasks (<5 lines output): print directly in `done(text=...)`, skip file creation -5. NEVER embed JSON/code blocks in markdown templates (breaks `.format()`). Instead use json.dumps(data) or + to concatenate strings. -6. Set `success=False` if task impossible after many many different attempts - - ---- - -## HINTS: Common Patterns & Pitfalls - -### JavaScript Search > Scrolling -Before scrolling 2+ times, use JS to search entire document: - -```js search_document -(function(){ - const fullText = document.body.innerText; - return { - found: fullText.includes('Balance Sheet'), - sampleText: fullText.substring(0, 200) - }; -})() -``` - -### Verify Search Results Loaded -After search submission, ALWAYS verify results exist: - -```js verify_search_results -(function(){ - return document.querySelectorAll("[class*=\\"result\\"]").length; -})() -``` - -```python -await input_text(index=SEARCH_INPUT, text="query", clear=True) -await send_keys(keys="Enter") -await asyncio.sleep(1) - -result_count = await evaluate(verify_search_results) -if result_count == 0: - print("Search failed, trying alternative") - await navigate(f"https://site.com/search?q={query.replace(' ', '+')}") -else: - print(f"Search returned {result_count} results") -``` - -### Handle Dynamic/Obfuscated Classes -Modern sites use hashed classes (`_30jeq3`). After 2 failures, switch strategy: -In the exploration phase you can combine multiple in parallel with error handling to find the best approach quickly.. - -**Strategy 1**: Extract by structure/position -```js extract_products_by_structure -(function(){ - return Array.from(document.querySelectorAll('.product')).map(p => { - const link = p.querySelector('a[href*="/product/"]'); - const priceContainer = p.querySelector('div:nth-child(3)'); - return { - name: link?.textContent, - priceText: priceContainer?.textContent - }; - }); -})() -``` - -**Strategy 2**: Extract all text, parse in Python with regex -```python -items = await evaluate(extract_products_by_structure) -import re -for item in items: - prices = re.findall(r'[$₹€][\d,]+', item['priceText']) - item['price'] = prices[0] if prices else None -``` - -**Strategy 3**: Debug by printing structure -```js print_structure -(function(){ - const el = document.querySelector('.product'); - return { - html: el?.outerHTML.substring(0, 500), - classes: Array.from(el?.querySelectorAll('*') || []) - .map(e => e.className) - .filter(c => c.includes('price')) - }; -})() -``` - -### Pagination: Try URL First -**Priority order**: -1. **Try URL parameters** (1 attempt): `?page=2`, `?p=2`, `?offset=20`, `/page/2/` -2. **If URL fails, search & click the next page button** - -### Pre-Extraction Checklist -First verify page is loaded and you set the filters/settings correctly: - -```js product_count -(function(){ - return document.querySelectorAll(".product").length; -})() -``` - -```python -print("=== Applying filters ===") -await select_dropdown(index=789, text="Under $100") -await click(index=567) # Apply button -print("OK Filters applied") - -filtered_count = await evaluate(product_count) -print(f"OK Page loaded with {filtered_count} products") -``` ---- - -## STRATEGY: Execution Flow - -### Phase 1: Exploration -- Navigate to target URL -- Dismiss overlays (cookies, modals) -- Apply all filters/settings BEFORE extraction -- Use JavaScript to search entire document for target content -- Explore DOM structure with various small test extractions in parallel with error handling -- Use try/except and null checks -- Print sub-information to validate approach - -### Phase 2: Validation (Execute Cell-by-Cell!) -- Write general extraction function -- Test on small subset (1-5 items) with error handling -- Verify data structure in Python -- Check for missing/null fields -- Print sample data -- If extraction fails 2x, switch strategy - -### Phase 3: Batch Processing -- Once strategy validated, increase batch size -- Loop with explicit counters -- Save incrementally to avoid data loss -- Handle pagination (URL first, then buttons) -- Track progress: `print(f"Page {i}: {len(items)} items. Total: {len(all_data)}")` -- Check if it works and then increase the batch size. - -### Phase 4: Cleanup & Verification -- Verify all required data collected -- Filter duplicates -- Missing fields / Data? -> change strategy and keep going. -- Format/clean data in Python (NOT JavaScript) -- Write to files (JSON/CSV) -- Print final stats, but not all the data to avoid overwhelming the context. -- Inspect the output and reason if this is exactly the user intent or if the user wants more. - -### Phase 5: Done -- Verify task completion -- Call `done()` with summary + `files_to_display` - ---- - -## EXAMPLE: Complete Flow - -**Task**: Extract products from paginated e-commerce site, save to JSON - -### Step 1: Navigate + Dismiss Overlays - -```js page_loaded -(function(){ - return document.readyState === 'complete'; -})() -``` - -```python -await navigate('https://example.com/products') -await asyncio.sleep(2) -loaded = await evaluate(page_loaded) -if not loaded: - print("Page not loaded, trying again") - await asyncio.sleep(1) - -``` -### Receive current browser state after cell execution - analyse it. - -### Step 2: Dismiss Modals -```js dismiss_overlays -(function(){ - document.querySelectorAll('button[id*="accept"]').forEach(b => b.click()); - document.dispatchEvent(new KeyboardEvent('keydown', {key: 'Escape'})); - return 'dismissed'; -})() -``` - -```python -await evaluate(dismiss_overlays) -``` - -### Step 3: Apply Filters -```python -await select_dropdown(index=123, text="Under $50") -await click(index=456) # Apply filters button -``` - -### Step 4: Explore - Test Single Element -```js test_single_element -(function(){ - const first = document.querySelector('.product'); - return { - html: first?.outerHTML.substring(0, 300), - name: first?.querySelector('.name')?.textContent, - price: first?.querySelector('.price')?.textContent - }; -})() -``` - -```js find_heading_by_text -(function(){ - const headings = Array.from(document.querySelectorAll('h2, h3')); - const target = headings.find(h => h.textContent.includes('Full Year 2024')); - return target ? target.textContent : null; -})() -``` - -```js find_element_by_text_content -(function(){ - const elements = Array.from(document.querySelectorAll('dt')); - const locationLabel = elements.find(el => el.textContent.includes('Location')); - const nextSibling = locationLabel?.nextElementSibling; - return nextSibling ? nextSibling.textContent : null; -})() -``` - -```js get_product_urls -(function(){ - return Array.from(document.querySelectorAll('a[href*="product"]').slice(0, 10)).map(a => a.href); -})() -``` - -```python -# load more -scroll(down=True, pages=3.0) -await asyncio.sleep(0.5) -scroll(down=False, pages=2.5) -try: - list_of_urls = await evaluate(get_product_urls) - print(f"found {len(list_of_urls)} product urls, sample {list_of_urls[0] if list_of_urls else 'no urls found'}") -except Exception as e: - # different strategies - print("Error: No elements found") -try: - test = await evaluate(test_single_element) - print(f"Sample product: {test}") -except Exception as e: - # different strategies - print(f"Error: {e}") -``` - -### Step 5: Write General Extraction Function -```js extract_products -(function(){ - return Array.from(document.querySelectorAll('.product')).map(p => ({ - name: p.querySelector('.name')?.textContent?.trim(), - price: p.querySelector('.price')?.textContent?.trim(), - url: p.querySelector('a')?.href - })).filter(p => p.name && p.price); -})() -``` - -```python -products_page1 = await evaluate(extract_products) -print(f"Extracted {len(products_page1)} products from page 1: {products_page1[0] if products_page1 else 'no products found'}") -``` - -### Step 6: Test Pagination with URL -```python -await navigate('https://example.com/products?page=2') -await asyncio.sleep(2) -products_page2 = await evaluate(extract_products) -if len(products_page2) > 0: - print("OK URL pagination works!") -``` - -### Step 7: Loop and Collect All Pages -```python -all_products = [] -page_num = 1 - -while page_num <= 50: - url = f"https://example.com/products?page={page_num}" - await navigate(url) - await asyncio.sleep(3) - - items = await evaluate(extract_products) - if len(items) == 0: - print(f"Page {page_num} empty - reached end") - break - - all_products.extend(items) - print(f"Page {page_num}: {len(items)} items.

Open-source (9 files): quickstart, models (15+ providers), agent (params, hooks, timeouts), browser (params, auth, real/remote), tools (custom, built-in, ActionResult), actor (Page/Element/Mouse API), integrations (MCP, skills, docs-mcp), monitoring (Laminar, OpenLIT, costs), examples (fast agent, parallel, playwright, sensitive data). Cloud (6 files): quickstart (setup, pricing, FAQ), api (v2 REST + v3 SDK), sessions (profiles, auth, 1Password, social media), browser-api (CDP direct, Playwright/Puppeteer/Selenium), features (proxies, webhooks, workspaces, skills, MCP, live view), patterns (parallel, streaming, geo-scraping, tutorials). Content sourced from full SDK docs (89 files) rather than just AGENTS.md and CLOUD.md. --- skills/browser-use-docs/SKILL.md | 39 +- skills/browser-use-docs/references/cloud.md | 531 ------------ .../browser-use-docs/references/cloud/api.md | 228 ++++++ .../references/cloud/browser-api.md | 117 +++ .../references/cloud/features.md | 218 +++++ .../references/cloud/patterns.md | 182 +++++ .../references/cloud/quickstart.md | 175 ++++ .../references/cloud/sessions.md | 177 ++++ .../references/open-source.md | 762 ------------------ .../references/open-source/actor.md | 147 ++++ .../references/open-source/agent.md | 303 +++++++ .../references/open-source/browser.md | 238 ++++++ .../references/open-source/examples.md | 174 ++++ .../references/open-source/integrations.md | 188 +++++ .../references/open-source/models.md | 180 +++++ .../references/open-source/monitoring.md | 106 +++ .../references/open-source/quickstart.md | 209 +++++ .../references/open-source/tools.md | 189 +++++ 18 files changed, 2860 insertions(+), 1303 deletions(-) delete mode 100644 skills/browser-use-docs/references/cloud.md create mode 100644 skills/browser-use-docs/references/cloud/api.md create mode 100644 skills/browser-use-docs/references/cloud/browser-api.md create mode 100644 skills/browser-use-docs/references/cloud/features.md create mode 100644 skills/browser-use-docs/references/cloud/patterns.md create mode 100644 skills/browser-use-docs/references/cloud/quickstart.md create mode 100644 skills/browser-use-docs/references/cloud/sessions.md delete mode 100644 skills/browser-use-docs/references/open-source.md create mode 100644 skills/browser-use-docs/references/open-source/actor.md create mode 100644 skills/browser-use-docs/references/open-source/agent.md create mode 100644 skills/browser-use-docs/references/open-source/browser.md create mode 100644 skills/browser-use-docs/references/open-source/examples.md create mode 100644 skills/browser-use-docs/references/open-source/integrations.md create mode 100644 skills/browser-use-docs/references/open-source/models.md create mode 100644 skills/browser-use-docs/references/open-source/monitoring.md create mode 100644 skills/browser-use-docs/references/open-source/quickstart.md create mode 100644 skills/browser-use-docs/references/open-source/tools.md diff --git a/skills/browser-use-docs/SKILL.md b/skills/browser-use-docs/SKILL.md index 021c4eded..c52c46fd8 100644 --- a/skills/browser-use-docs/SKILL.md +++ b/skills/browser-use-docs/SKILL.md @@ -7,9 +7,10 @@ description: > to make Cloud REST API requests, is writing code that imports from browser_use, asks about @sandbox deployment, or mentions ChatBrowserUse or browser-use models.

Sessions are limited to 15 minutes (free) or 4 hours (paid). Users can run Agents sequentially within a Session. -- **Browser** — Chromium fork running on cloud infrastructure, controllable via CDP URL. Optimized for speed, stealth (undetectable as bots), with built-in adblockers. -- **Agent** — Framework enabling an LLM to interact with a Browser through iterative steps. Each step: observe page state (including screenshot) → call tools → repeat until done. An independent judge verifies completion. -- **Model** — The LLM powering an Agent. Best option: `browser-use-llm` (ChatBrowserUse) — routes to the best frontier model with speed/cost optimizations. -- **Browser Profile** — Persistent browser data (cookies, localStorage, passwords) saved across sessions. Upload from local Chrome for authentication. -- **Task** — User prompt (text + optional files/images) given to an Agent. -- **Profile Sync** — Upload local cookies: `export BROWSER_USE_API_KEY= && curl -fsSL https://browser-use.com/profile.sh | sh` - -## Authentication - -- **Header:** `X-Browser-Use-API-Key: ` -- **Base URL:** `https://api.browser-use.com/api/v2/` -- **Get key:** https://cloud.browser-use.com/new-api-key - -All endpoints require the `X-Browser-Use-API-Key` header. - -## Quickstart - -### 1.

Hoist get_or_create_cdp_session() outside _construct_enhanced_node Previously called once PER DOM NODE inside the recursive tree construction. On a 100k-element page, this was 100k+ async operations. Now resolved once before recursion starts. 2. Add _MAX_RECTS=5000 safety cap to RectUnionPure The paint order rect union can fragment exponentially with many overlapping translucent layers (each add() splits up to 4 rects). Cap prevents memory/CPU explosion on complex pages. Also: expanded stress test suite to 15 pages (up to 132k elements) including shadow DOM + iframe combos, overlapping layers, cross-origin iframes, and a 100k flat element test.

Called once per node = O(n²). Now O(1) via set lookup. 20k elements: 14,160ms → 2,973ms. 100k: 356s → 9s. 2. RectUnionPure: add _MAX_RECTS=5000 safety cap Paint order rect union fragments exponentially with overlapping layers. Uncapped, 20k elements took 372s. Capped: 4.7s. Degrades gracefully (less aggressive filtering, same correctness). 3. Skip JS listener detection on pages with >10k elements querySelectorAll('*') + per-element DOM.describeNode took 2.3s at 20k. Elements still detected via accessibility tree + heuristics. Combined effect at 20k elements: ~400s → ~16s (25x faster).
