+# [FEATURE] Click task to open editable details
+
+## Description
+When I click a task, open details and let me update description.
+
+## User Story
+As a user, I want to click a task to view and edit its description inline.
+
+## Technical Context
+- Extends existing task display with detail view
+- Requires new endpoints for fetching and updating task details
+- HTMX-powered modal or slide-out panel
+
+## Test Strategy
+
+### Unit Test (Red)
+**File:** `internal/handlers/handlers_test.go`
+
+```go
+func TestUpdateTaskDescription(t *testing.T) {
+    // Setup mock Todoist client
+    mockClient := &MockTodoistClient{}
+    handler := NewHandler(mockClient)
+
+    // Call update endpoint
+    req := httptest.NewRequest("PUT", "/tasks/123",
+        strings.NewReader(`{"description": "Updated desc"}`))
+
+    // Assert Todoist API called with correct params
+    mockClient.AssertCalled(t, "UpdateTask", "123", "Updated desc")
+}
+```
+
+### E2E Test (Red)
+```
+1. Click on a task row
+2. Assert modal/drawer opens with task details
+3. Assert description field is editable
+4. Edit description and save
+5. Assert modal closes
+6. Assert description persisted (re-open to verify)
+```
+
+## Proposed Approach
+
+1. **Endpoints:**
+   - `GET /tasks/{id}/detail` — fetch task with full details
+   - `PUT /tasks/{id}` — update task (description, etc.)
+
+2. **UI Flow:**
+   - Click task row triggers `hx-get="/tasks/{id}/detail"`
+   - Response loads into modal or slide-out panel
+   - Form with editable description (textarea)
+   - Save button triggers `hx-put="/tasks/{id}"`
+   - On success, close modal and optionally update task row
+
+3. **Template:**
+   - New partial: `partials/task-detail.html`
+   - Contains: title (read-only or editable), description (editable), due date, labels, save/cancel buttons
+
+4. **API Integration:**
+   - Update Todoist via API when saving
+   - Update local cache
+
+## Affected Components
+- `internal/handlers/handlers.go` (new endpoints)
+- `internal/handlers/handlers_test.go`
+- `internal/api/todoist.go` (UpdateTask method if not exists)
+- `web/templates/partials/task-detail.html` (new)
+- `web/templates/partials/todoist-tasks.html` (add click handler)
+- `web/templates/index.html` (modal container if needed)
+
+## Definition of Done
+- [ ] Clicking task opens detail view
+- [ ] Description field is editable
+- [ ] Save persists to Todoist
+- [ ] Local cache updated
+- [ ] Modal/drawer closes on save
+- [ ] Unit tests for update handler
+- [ ] E2E test for full flow
