    "incantation": "When recording a site's API traffic, start HAR capture; text-like response bodies are embedded by default. Choose `--content all` for all bodies or `--content none` for metadata only, then stop capture to save the HAR.",
    "examples": [
      "agent-browser network har start\nagent-browser open <url>\nagent-browser network har stop <output.har>",
      "agent-browser network har start --content all",

      "Version: v0.32.3",
      "--content: Select body capture mode: `text` (default; text-like bodies, up to 2 MB per body), `all` (all bodies; binary as base64), or `none` (sizes and MIME types only). These are alternative values for one option.",
      "<url> (required): URL to open while recording.",
      "<output.har>: Path to save the HAR when stopping recording; if omitted, a temporary path is used.",
      "Text-like response bodies are embedded by default, up to 2 MB per body.",
      "The `all` mode embeds binary content as base64.",
      "The `none` mode records sizes and MIME types without bodies.",
      "HAR files include request headers, response headers, cookies, POST data, and response bodies; treat them as sensitive when pages use cookies, bearer tokens, or API keys."
