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\nAccent rendered text and add padding inside each ICU plural, select and selectordinal branch. Object keys and non-string values stay unchanged. Preserve argument names, selectors, offsets, # substitutions, quoted syntax, nested placeholders, HTML tags, entities and printf tokens. Simple brace/template placeholders and formatted arguments stay opaque. ICU requires unique selectors and an other branch; malformed or unsupported argument types are rejected.

CSV uses exact JSON Pointer paths and typed JSON value envelopes for spreadsheet-safe reporting.\n\n### Inputs and settings\n\nText input: JSON input.\n\nExample or placeholder shown in the interface (not a validated fixture):\n\n```text\n{\n \"welcome\": \"Hello {name}\",\n \"count\": \"Items: %d\",\n \"button\": \"Save & close\",\n \"active\": true\n}\n```\n\nAccent rendered text and add padding inside each ICU plural, select and selectordinal branch. Object keys and non-string values stay unchanged. Preserve argument names, selectors, offsets, # substitutions, quoted syntax, nested placeholders, HTML tags, entities and printf tokens. Simple brace/template placeholders and formatted arguments stay opaque. ICU requires unique selectors and an other branch; malformed or unsupported argument types are rejected. Padding counts literal code points rather than protected syntax. This is a layout test, not a translation. Expansion ranges from zero to 300 percent. Up to 1,000,000 characters. Review the settings before running.\n\n| Setting | Meaning | Control type | Default | Constraints |\n| --- | --- | --- | --- | --- |\n| `format` | Input format | select | \"JSON resource bundle\" | Allowed: JSON resource bundle, Plain text |\n| `expansion` | Expansion percent | text | \"30\" | |\n| `wrap` | String wrapping | select | \"Wrap strings\" | Allowed: Wrap strings, No wrapping |\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\nAccent rendered text and add padding inside each ICU plural, select and selectordinal branch. Object keys and non-string values stay unchanged. Preserve argument names, selectors, offsets, # substitutions, quoted syntax, nested placeholders, HTML tags, entities and printf tokens.
