+name: "Display forecast wind direction (TWD) in instrument sheet"
+description: "MarineConditions.windDirDeg is fetched from Open-Meteo and stored in the model but never displayed anywhere. Show it as a sub-label under the TWS cell."
+agent:
+  model: "sonnet"
+  working_dir: "/workspace/nav"
+  instructions: |
+    Context
+    -------
+    fetchCurrentConditions() in WeatherRepository populates MarineConditions.windDirDeg
+    from the Open-Meteo hourly winddirection_10m field (in degrees true).
+        (android-app/app/src/main/kotlin/org/terst/nav/data/repository/WeatherRepository.kt, line ~63)
+        (android-app/app/src/main/kotlin/org/terst/nav/data/model/MarineConditions.kt, line 9)
+
+    In MainActivity.observeDataSources(), the marineConditions collector reads windSpeedKt
+    (displays as TWS) but never reads windDirDeg:
+        (android-app/app/src/main/kotlin/org/terst/nav/MainActivity.kt, marineConditions collector)
+
+    The instrument sheet layout has a TWS cell:
+        (android-app/app/src/main/res/layout/layout_instruments_sheet.xml)
+        <TextView android:id="@+id/value_tws" style="@style/InstrumentPrimaryValue" />
+
+    Goal
+    ----
+    Show wind direction as a secondary line below the TWS value (e.g. "045°") using the
+    same pattern used for curr_dir below curr_spd in the conditions section.
+
+    Step 1 — Add value_twd TextView to layout
+    ------------------------------------------
+    In android-app/app/src/main/res/layout/layout_instruments_sheet.xml,
+    find the TWS LinearLayout:
+
+        <LinearLayout ... android:gravity="center" android:padding="8dp">
+            <TextView style="@style/InstrumentLabel" android:text="TWS" />
+            <TextView android:id="@+id/value_tws" style="@style/InstrumentPrimaryValue" tools:text="—" />
+        </LinearLayout>
+
+    Add a third child TextView for the direction:
+
+        <LinearLayout ... android:gravity="center" android:padding="8dp">
+            <TextView style="@style/InstrumentLabel" android:text="TWS" />
+            <TextView android:id="@+id/value_tws" style="@style/InstrumentPrimaryValue" tools:text="—" />
+            <TextView android:id="@+id/value_twd" style="@style/InstrumentLabel" tools:text="—" />
+        </LinearLayout>
+
+    Step 2 — Add valueTwd field to InstrumentHandler
+    -------------------------------------------------
+    In android-app/app/src/main/kotlin/org/terst/nav/ui/InstrumentHandler.kt:
+
+    Add constructor parameter:
+        private val valueTwd: TextView
+
+    Add twd parameter to updateDisplay():
+        twd: String? = null
+
+    Add in the updateDisplay body:
+        twd?.let { valueTwd.text = it }
+
+    Step 3 — Wire in MainActivity
+    ------------------------------
+    In android-app/app/src/main/kotlin/org/terst/nav/MainActivity.kt,
+    in setupHandlers(), add to InstrumentHandler constructor:
+        valueTwd = findViewById(R.id.value_twd)
+
+    In setupHandlers(), add "—" initial value:
+        instrumentHandler?.updateDisplay(..., twd = "—")
+
+    In observeDataSources(), in the marineConditions collector, add:
+        instrumentHandler?.updateDisplay(
+            tws = c.windSpeedKt?.let { "%.1f".format(Locale.getDefault(), it) } ?: "—",
+            twd = c.windDirDeg?.let { "%.0f°".format(Locale.getDefault(), it) } ?: "—"
+        )
+
+    Step 4 — Build
+    --------------
+    cd android-app && ANDROID_HOME=/opt/android-sdk ./gradlew assembleDebug 2>&1 | tail -5
+    Confirm BUILD SUCCESSFUL.
+
+    Step 5 — Commit and push
+    ------------------------
+    git add android-app/app/src/main/res/layout/layout_instruments_sheet.xml \
+            android-app/app/src/main/kotlin/org/terst/nav/ui/InstrumentHandler.kt \
+            android-app/app/src/main/kotlin/org/terst/nav/MainActivity.kt
+    git commit -m "feat(instruments): display forecast wind direction (TWD) under TWS cell
+
+    windDirDeg was fetched from Open-Meteo and stored in MarineConditions
+    but never shown. Adds value_twd sub-label below the TWS primary value."
