Registration alone is not a production-quality guarantee. |\n| Browser execution | Automatic updates after valid input or file selection. |\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\nConvert area and remaining target depth to a water volume. Effective rain and application efficiency are entered assumptions, not a weather or crop recommendation. Runs on your device. Changing units keeps the entered numbers.\n\n### Inputs and settings\n\nNo free-text input is required. Use the file inputs and/or settings below.\n\n| Setting | Meaning | Control type | Default | Constraints |\n| --- | --- | --- | --- | --- |\n| `area` | Area receiving water | number | 20 | min=0 max=1000000000 step=any |\n| `areaUnit` | Area unit | select | \"m²\" | Allowed: m², ft², yd², acre, hectare |\n| `targetDepth` | Desired depth for the same period | number | 20 | min=0 max=1000000000 step=any |\n| `rainDepth` | Effective rainfall already contributing | number | 5 | min=0 max=1000000000 step=any |\n| `depthUnit` | Water depth unit | select | \"mm\" | Allowed: mm, cm, m, in, ft |\n| `efficiency` | Application efficiency (%) | number | 80 | min=0 max=100 step=any |\n| `outputUnit` | Output water unit | select | \"L\" | Allowed: L, m³, US gal, Imp gal, ft³, yd³ |\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\nArea, rain, desired depth and efficiency are user inputs. This is a volume conversion, not a crop schedule, soil model or weather forecast.\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\": \"garden-irrigation-calculator\",\n \"category\": \"calculators\",\n \"built\": true,\n \"requirements\": \"Area, rain, desired depth and efficiency are user inputs.
