Registration alone is not a production-quality guarantee. |\n| Browser execution | Use the visible action or interactive controls. |\n| Browser processing | Browser; see tool notes for network behavior. |\n| HTTP API | Not callable through HTTP. |\n| Browser-agent interface | run_current_tool |\n\n### Implementation notes\n\nInspect names, relative paths and file sizes locally. No file contents are read. Empty folders and inaccessible entries are not exposed by the browser folder picker.\n\n### Inputs and settings\n\nNo free-text input is required. Use the file inputs and/or settings below.\n\nAccepted browser files: `See implementation notes`. Multiple files are supported.\n\nBrowser file-input limit: no total size limit. HTTP limits can differ.\n\nNo additional settings are declared for this tool.\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\nUp to 2,000 selected files. Examines names and sizes only. These conservative Windows, macOS and Linux checks do not simulate every filesystem or permissions configuration.\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\": \"filename-portability-checker\",\n  \"category\": \"developer-tools\",\n  \"built\": true,\n  \"requirements\": \"Up to 2,000 selected files.
