Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nN-up layout with paper size, margins and reading order preview.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n \"id\": \"pages-per-sheet\",\n \"category\": \"pdf-tools\",\n \"built\": true,\n \"requirements\": \"N-up layout with paper size, margins and reading order preview.\",\n \"implementation\": {\n \"fields\": [\n {\n \"key\": \"columns\",\n \"label\": \"Columns\",\n \"value\": 2,\n \"type\": \"number\"\n },\n {\n \"key\": \"rows\",\n \"label\": \"Rows\",\n \"value\": 1,\n \"type\": \"number\"\n }\n ],\n \"files\": true,\n \"input\": false,\n \"accept\": \".pdf\",\n \"note\": \"Fits pages onto landscape A4 sheets.
