+
+            ## Code Quality Requirements
+
+            After making any code changes, you MUST run the appropriate validation commands:
+
+            **Frontend Changes:**
+            - Run: `npm run check` in the frontend directory
+            - Fix all warnings and errors before proceeding
+
+            **Backend Changes:**  
+            - Run: `cargo check --features $(./all_features_oss.sh)` in the backend directory
+            - Fix all warnings and errors before proceeding
+
+            **Pull Request Creation:**
+            - DO NOT FORGET TO OPEN A DRAFT PR AFTER YOU ARE DONE if you made changes after a request from a git issue.

+# Frontend Development (Svelte 5)
+
+## Core Principles
+
+- Follow @svelte5-best-practices.mdc for detailed guidelines
+- Use Runes ($state, $derived, $effect) for reactivity
+- Keep components small and focused
+- Always use keys in {#each} blocks
+
+## UI Guidelines
+
+- Follow existing design system
+- Use consistent spacing and colors
+
+## Backend API
+
+- If you need to call the backend API, you can find the available routes in ../backend/windmill-api/openapi.yaml
+- You can also use the associated types and services that are auto generated from the openapi file. They are in src/lib/gen/\*gen.ts files
+
+### OpenAPI Autogeneration
+
+Windmill automatically generates TypeScript types and services from the OpenAPI specification.
+
+#### Service Generation Pattern
+
+The autogeneration follows this pattern:
+
+- **Tag** → **Service Name**: The OpenAPI tag becomes the service name with "Service" suffix
+- **operationId** → **Method Name**: The operationId becomes the method name in the service
+
+#### Example
+
+Given this OpenAPI specification:
+
+```yaml
+/w/{workspace}/audit/list:
+  get:
+    summary: list audit logs (requires admin privilege)
+    operationId: listAuditLogs
+    tags:
+      - audit
+    parameters:
+      - $ref: '#/components/parameters/WorkspaceId'
+      - $ref: '#/components/parameters/Page'
+      - $ref: '#/components/parameters/PerPage'
+      - $ref: '#/components/parameters/Before'
+      - $ref: '#/components/parameters/After'
+      - $ref: '#/components/parameters/Username'
+      - $ref: '#/components/parameters/Operation'
+      - name: operations
+        in: query
+        description: comma separated list of exact operations to include
+        schema:
+          type: string
+```
+
+This generates:
+
+- **Service**: `AuditService` (from tag "audit")
+- **Method**: `listAuditLogs` (from operationId)
+
+#### Method Arguments
+
+The generated method arguments correspond to the OpenAPI parameters:
+
+```typescript
+AuditService.listAuditLogs({
+  workspace: string,           // from WorkspaceId parameter
+  page?: number,              // from Page parameter
+  perPage?: number,           // from PerPage parameter
+  before?: string,            // from Before parameter
+  after?: string,             // from After parameter
+  username?: string,          // from Username parameter
+  operation?: string,         // from Operation parameter
+  operations?: string         // from operations parameter
+})
+```
