Named pages created with `browser.getPage(\"name\")` persist within that browser between script runs.\n          \n          Defaults to `default`.\n          \n          [default: default]\n\n      --connect [<URL>]\n          Connect to a running Chrome instance.\n          \n          Without a URL: auto-discovers Chrome with debugging enabled.\n          Works with Chrome's built-in remote debugging\n          (chrome://inspect/#remote-debugging) and classic\n          --remote-debugging-port mode.\n          \n          With a URL: connects to the specified CDP endpoint.\n          Accepts HTTP or WebSocket CDP endpoints such as `http://localhost:9222` or `ws://host:9222/devtools/browser/...`.\n          \n          To launch Chrome with debugging, use a command such as:\n            chrome.exe --remote-debugging-port=9222\n            google-chrome --remote-debugging-port=9222\n          \n          Or visit chrome://inspect/#remote-debugging to configure.\n\n      --headless\n          Launch or relaunch daemon-managed Chromium in headless mode.\n          \n          This only affects daemon-launched browsers. It has no effect when `--connect` attaches to an already-running external browser.\n\n      --ignore-https-errors\n          Launch or relaunch daemon-managed Chromium with HTTPS certificate errors ignored.\n          \n          This is useful for self-signed certificates in local or staging environments. The setting applies per managed browser session until the daemon restarts or the setting changes and triggers a relaunch.\n          \n          This only affects daemon-launched browsers. It has no effect when `--connect` attaches to an already-running external browser.\n\n      --timeout <SECONDS>\n          Maximum script execution time in seconds.\n          \n          If the script exceeds this limit, the daemon terminates it and returns an error.\n          \n          Defaults to 30 seconds.\n          \n          [default: 30]\n\n  -h, --help\n          Print help (see a summary with '-h')\n\nLLM USAGE GUIDE:\n  Write small, focused scripts. Each script should do ONE thing: navigate, click, fill, or check.\n  End each script by logging the state you need for the next decision.\n  Use descriptive page names like \"login\", \"checkout\", or \"results\" instead of \"page1\".\n  Named pages from browser.getPage(\"name\") persist between script runs, so you usually do not need to re-navigate.\n  Inside page.evaluate(...), write plain JavaScript only - no TypeScript syntax in the browser context.\n\n  Quick inspection:\n    dev-browser --connect <<'EOF'\n    const tabs = await browser.listPages();\n    console.log(JSON.stringify(tabs, null, 2));\n    EOF\n\n    dev-browser --connect <<'EOF'\n    const page = await browser.getPage(\"TARGET_ID_HERE\");\n    console.log(JSON.stringify({\n      url: page.url(),\n      title: await page.title(),\n    }, null, 2));\n    EOF\n\n  AI snapshots for element discovery:\n    dev-browser <<'EOF'\n    const page = await browser.getPage(\"main\");\n    const result = await page.snapshotForAI();\n    console.log(result.full);\n    // Returns { full: string, incremental?: string }.\n    // Optional args: { track?: string, depth?: number, timeout?: number }.\n    // Read result.full to identify the right element.\n    // Then interact with it using Playwright:\n    // await page.getByRole(\"button\", { name: \"Continue\" }).click();\n    // Re-run page.snapshotForAI({ track: \"main\" }) after the page changes.\n    EOF\n\n  Choosing your approach:\n    Unknown pages: use page.snapshotForAI() first to discover the page, then interact based on what you find.\n    Known pages/selectors: skip the snapshot and use direct Playwright selectors like page.click(), page.fill(), or page.locator() for faster, more reliable automation.\n\n  Screenshots for visual state:\n    dev-browser <<'EOF'\n    const page = await browser.getPage(\"main\");\n    const buf = await page.screenshot();\n    const path = await saveScreenshot(buf, \"debug.png\");\n    console.log(path);\n    EOF\n\n  Waiting patterns:\n    dev-browser <<'EOF'\n    const page = await browser.getPage(\"search-results\");\n    await page.waitForSelector(\".results\");\n    await page.waitForURL(\"**/success\");\n    console.log(JSON.stringify({\n      url: page.url(),\n      title: await page.title(),\n    }, null, 2));\n    EOF\n\n  Error recovery:\n    If a script fails, the page usually stays where it stopped.\n    Reconnect to the same page name, take a screenshot, and log the URL/title:\n    dev-browser <<'EOF'\n    const page = await browser.getPage(\"checkout\");\n    const path = await saveScreenshot(await page.screenshot(), \"debug.png\");\n    console.log(JSON.stringify({\n      screenshot: path,\n      url: page.url(),\n      title: await page.title(),\n    }, null, 2));\n    EOF\n\n  Common Playwright Page methods:\n    page.goto(url)                         Navigate to a URL\n    page.title()                           Get the current page title\n    page.url()                             Get the current URL\n    page.snapshotForAI(options)            Get an AI-optimized snapshot; returns { full, incremental?

Each script should do ONE thing: navigate, click, fill, or check.\n  End each script by logging the state you need for the next decision.\n  Use descriptive page names like \"login\", \"checkout\", or \"results\" instead of \"page1\".\n  Named pages from browser.getPage(\"name\") persist between script runs, so you usually do not need to re-navigate.\n  Inside page.evaluate(...), write plain JavaScript only - no TypeScript syntax in the browser context.\n\n  Quick inspection:\n    dev-browser --connect <<'EOF'\n    const tabs = await browser.listPages();\n    console.log(JSON.stringify(tabs, null, 2));\n    EOF\n\n    dev-browser --connect <<'EOF'\n    const page = await browser.getPage(\"TARGET_ID_HERE\");\n    console.log(JSON.stringify({\n      url: page.url(),\n      title: await page.title(),\n    }, null, 2));\n    EOF\n\n  AI snapshots for element discovery:\n    dev-browser <<'EOF'\n    const page = await browser.getPage(\"main\");\n    const result = await page.snapshotForAI();\n    console.log(result.full);\n    // Returns { full: string, incremental?: string }.\n    // Optional args: { track?: string, depth?: number, timeout?: number }.\n    // Read result.full to identify the right element.\n    // Then interact with it using Playwright:\n    // await page.getByRole(\"button\", { name: \"Continue\" }).click();\n    // Re-run page.snapshotForAI({ track: \"main\" }) after the page changes.\n    EOF\n\n  Choosing your approach:\n    Unknown pages: use page.snapshotForAI() first to discover the page, then interact based on what you find.\n    Known pages/selectors: skip the snapshot and use direct Playwright selectors like page.click(), page.fill(), or page.locator() for faster, more reliable automation.\n\n  Screenshots for visual state:\n    dev-browser <<'EOF'\n    const page = await browser.getPage(\"main\");\n    const buf = await page.screenshot();\n    const path = await saveScreenshot(buf, \"debug.png\");\n    console.log(path);\n    EOF\n\n  Waiting patterns:\n    dev-browser <<'EOF'\n    const page = await browser.getPage(\"search-results\");\n    await page.waitForSelector(\".results\");\n    await page.waitForURL(\"**/success\");\n    console.log(JSON.stringify({\n      url: page.url(),\n      title: await page.title(),\n    }, null, 2));\n    EOF\n\n  Error recovery:\n    If a script fails, the page usually stays where it stopped.\n    Reconnect to the same page name, take a screenshot, and log the URL/title:\n    dev-browser <<'EOF'\n    const page = await browser.getPage(\"checkout\");\n    const path = await saveScreenshot(await page.screenshot(), \"debug.png\");\n    console.log(JSON.stringify({\n      screenshot: path,\n      url: page.url(),\n      title: await page.title(),\n    }, null, 2));\n    EOF\n\n  Common Playwright Page methods:\n    page.goto(url)                         Navigate to a URL\n    page.title()                           Get the current page title\n    page.url()                             Get the current URL\n    page.snapshotForAI(options)            Get an AI-optimized snapshot; returns { full, incremental?
