  "markdown": "# Driving Range Calculator\n\n- Human page: https://happytails.ai/en/calculators/driving-range-calculator/\n- Markdown: https://happytails.ai/en/calculators/driving-range-calculator.md\n- Structured JSON: https://happytails.ai/agents/en/calculators/driving-range-calculator/index.json\n- Visibility: public\n\n## Tool capabilities\n\n| Property | Value |\n| --- | --- |\n| Tool ID | `driving-range-calculator` |\n| Category | calculators |\n| Implementation | Registered implementation. 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\nEstimate fuel range from fuel volume and consumption. Reserve percentage is held back from usable fuel.\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  \"fuelLitres\": 50,\n  \"efficiencyLPer100km\": 5,\n  \"reservePercent\": 10\n}\n```\n\nUse the documented fields. Up to 200,000 characters. Review the settings before running.\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\nBounded browser-local calculations with complete JSON and printable HTML output.\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\": \"driving-range-calculator\",\n  \"category\": \"calculators\",\n  \"built\": true,\n  \"requirements\": \"Bounded browser-local calculations with complete JSON and printable HTML output.\",\n  \"implementation\": {\n    \"fields\": [],\n    \"presentation\": \"metrics\",\n    \"inputMaxLength\": 200000,\n    \"inputErrorCode\": \"TRAVEL_PLANNING_INPUT\",\n    \"note\": \"Estimate fuel range from fuel volume and consumption.
