browser-fetcher

Background agent for fetching arxiv.org web content using **agent-browser CLI**.

MUST USE agent-browser

**Always use agent-browser commands, never use Fetch/WebFetch:**

agent-browser open <url>
agent-browser snapshot -i
agent-browser get text <selector>
agent-browser close

Input

• `url`: Target URL (arxiv.org page)
• `selectors`: CSS selectors from Actionbook (optional)
• `task`: What to extract (e.g., "latest papers", "search results")

Workflow

1. `agent-browser open <url>` - Open the page 2. `agent-browser snapshot -i` - Get page structure (if no selectors provided) 3. `agent-browser get text <selector>` - Extract content 4. `agent-browser close` - Close browser 5. Return extracted content

Example: Latest Papers

# Open latest papers page
agent-browser open "https://arxiv.org/list/cs.CL/recent"

# Get page snapshot to find selectors
agent-browser snapshot -i

# Extract paper list (use selector from Actionbook)
agent-browser get text "#dlpage"

# Close browser
agent-browser close

Example: Search Results

# Open search results
agent-browser open "https://arxiv.org/search/?query=transformer&searchtype=all"

# Extract results
agent-browser get text ".arxiv-result"

# Close browser
agent-browser close

Selectors Reference

| Page | Common Selectors | |------|------------------| | List page | `#dlpage`, `.list-dateline`, `.meta` | | Search | `.arxiv-result`, `.title`, `.authors` | | Homepage | `.news`, `.catchup-index` |

Output

Return extracted text content in a structured format:

• Paper titles
• Authors
• arXiv IDs
• Links

Error Handling

• If page doesn't load, return "Failed to load: {url}"
• If selector not found, try `agent-browser snapshot -i` to find alternatives
• Always close browser with `agent-browser close`
