# Work Session Summary: Rule and Pack Create/Edit Forms

**Date**: 2026-01-19  
**Focus**: Web UI form implementation for rules and packs with config schema support  
**Status**: ✅ Complete

---

## Overview

Implemented comprehensive create/edit forms for rules and packs in the Attune web UI, enabling users to:
- Create automation rules with dynamic trigger/action selection
- Register ad-hoc packs with JSON Schema-based configuration definitions
- Edit existing rules and packs (form components support both modes)

---

## Implemented Components

### 1. RuleForm Component (`web/src/components/forms/RuleForm.tsx`)

**Features**:
- Dynamic pack selection with cascading trigger/action dropdowns
- Automatic filtering of triggers and actions by selected pack
- JSON editor for match criteria with syntax validation
- JSON editor for action parameters with template variable support
- Form validation (required fields, JSON syntax)
- Create and update operations via React Query mutations
- Disabled fields for immutable data when editing (pack, trigger, action)
- Auto-navigation to detail page after successful creation
- Error handling and user feedback

**Form Fields**:
- Pack selection (dropdown, required)
- Name (text, required)
- Description (textarea, optional)
- Enabled toggle (default: true)
- Trigger selection (dropdown, required, filtered by pack)
- Match criteria (JSON textarea, optional)
- Action selection (dropdown, required, filtered by pack)
- Action parameters (JSON textarea, optional)

**Validation**:
- Name: non-empty string required
- Pack: must be selected
- Trigger: must be selected
- Action: must be selected
- Criteria: valid JSON or empty
- Action parameters: valid JSON or empty

### 2. PackForm Component (`web/src/components/forms/PackForm.tsx`)

**Features**:
- Pack name format validation (lowercase, numbers, hyphens, underscores)
- Semantic versioning validation
- Configuration schema JSON editor with validation
- Quick-insert buttons for common schema examples (API, Database, Webhook)
- Additional metadata JSON editor
- Automatic merging of config_schema into metadata
- System and enabled toggles
- Create and update operations
- Error handling and user feedback

**Form Fields**:
- Name (text, required, immutable when editing)
- Description (textarea, optional)
- Version (text, required, semver format)
- Author (text, optional)
- Enabled toggle (default: true)
- System toggle (default: false)
- Configuration schema (JSON textarea, JSON Schema format)
- Additional metadata (JSON textarea, optional)

**Validation**:
- Name: required, must match pattern `^[a-z0-9_-]+$`
- Version: required, must match semver pattern `^\d+\.\d+\.\d+`
- Config schema: valid JSON, must have `type: "object"` at root
- Metadata: valid JSON or empty

**Quick-Insert Examples**:
- **API Schema**: API key, endpoint, authentication
- **Database Schema**: Host, port, database, username, password
- **Webhook Schema**: Webhook URL, auth token, timeout

### 3. Page Components

**RuleCreatePage** (`web/src/pages/rules/RuleCreatePage.tsx`):
- Simple wrapper around RuleForm
- Header with breadcrumb navigation
- Descriptive text for user guidance

**PackCreatePage** (`web/src/pages/packs/PackCreatePage.tsx`):
- Simple wrapper around PackForm
- Header with breadcrumb navigation
- Descriptive text for user guidance

### 4. Routing Updates

**Added Routes**:
- `/rules/new` → RuleCreatePage
- `/packs/new` → PackCreatePage

**Route Order**: New routes placed before `:id` routes to prevent path conflicts

### 5. List Page Enhancements

**RulesPage**:
- Added "Create Rule" button in header
- Button navigates to `/rules/new`
- Styled consistently with existing UI

**PacksPage**:
- Added "Register Pack" button in header
- Button navigates to `/packs/new`
- Enhanced header layout and description
- Styled consistently with existing UI

---

## Technical Implementation Details

### React Query Integration

Both forms use existing hooks:
- `useCreateRule()` / `useUpdateRule()` for rule operations
- `useCreatePack()` / `useUpdatePack()` for pack operations
- `usePacks()` for loading pack list
- `usePackTriggers()` / `usePackActions()` for filtered dropdowns
- Automatic query invalidation after mutations

### Form State Management

- Local state with React `useState` hooks
- Separate error state for field-level validation
- JSON parsing/stringification for complex fields
- Effect hook to reset cascading dropdowns on pack change

### Validation Strategy

**Client-Side Validation**:
- Required field checks
- Format validation (pack name, version)
- JSON syntax validation
- Real-time error display

**Server-Side Validation**:
- API error capture and display
- Generic error handling for network failures

### User Experience

- Inline validation errors with red borders and messages
- Submit button disabled during API calls
- Loading states ("Saving...")
- Success navigation (redirect to detail page)
- Cancel button returns to list page
- Helpful placeholder text and examples
- Required field indicators (red asterisks)
- Informational hints below complex fields

---

## Configuration Schema Support

The pack form allows defining a JSON Schema for pack configuration, enabling:

1. **Schema Definition**: Define expected configuration structure
2. **Type Validation**: Specify types (string, integer, object, etc.)
3. **Constraints**: Min/max values, enums, required fields
4. **Defaults**: Provide default values
5. **Documentation**: Add descriptions for each field

**Example Schema Structure**:
```json
{
  "type": "object",
  "properties": {
    "api_key": {
      "type": "string",
      "description": "API key for authentication"
    },
    "endpoint": {
      "type": "string",
      "description": "Service endpoint URL",
      "default": "https://api.example.com"
    },
    "timeout": {
      "type": "integer",
      "minimum": 1,
      "maximum": 300,
      "default": 30
    }
  },
  "required": ["api_key"]
}
```

**Storage**: Config schema is merged into pack metadata under `config_schema` key

## Architectural Clarification

**Important**: During this session, architectural constraints were clarified:

### Pack-Based vs UI-Configurable Components

**Actions and Sensors** - **NOT UI-Editable**:
- Implemented as executable code (Python, Node.js, Shell)
- Registered when a pack is loaded/installed
- Managed through pack lifecycle, not through Web UI
- Rationale: Security, performance, code quality, testing

**Triggers** - **Mixed Model**:
- **Pack-based triggers**: Registered with system packs (e.g., `slack.message_received`)
- **Ad-hoc triggers**: UI-configurable for custom integrations (future feature)
- Only ad-hoc triggers in ad-hoc packs should be editable via UI

**Rules** - **Always UI-Configurable**:
- Connect triggers to actions with criteria and parameters
- No code execution, just data mapping
- Users need flexibility to change business logic

**Packs** - **Two Types**:
- **System packs**: Installed via pack management tools, contain code-based components
- **Ad-hoc packs**: Registered via UI for custom event types without code deployment

**Workflow Actions** - **Future**:
- Special type of action that will be UI-configurable
- Part of visual workflow editor implementation

### Documentation Created

- `docs/pack-management-architecture.md` - Comprehensive architectural guidelines
- Updated `TODO.md` with architectural notes
- Updated `CHANGELOG.md` with clarifications

### Impact on Implementation Plans

**Previously Planned** (now removed):
- ❌ Action create/edit forms (actions are code-based)
- ❌ Sensor create/edit forms (sensors are code-based)

**Still Needed**:
- ✅ Trigger create/edit form (for ad-hoc packs only)
- ✅ Workflow action configuration (future feature)

## Conclusion

Successfully implemented full-featured create/edit forms for rules and packs, completing a major milestone in the Attune web UI. The forms provide:

- **Intuitive UX** with cascading dropdowns and real-time validation
- **Powerful Features** like JSON Schema-based pack configuration
- **Production Quality** with proper error handling and loading states
- **Extensibility** supporting both create and edit modes
- **Architectural Clarity** on pack-based vs UI-configurable components

The implementation follows established patterns from existing pages and integrates seamlessly with the API and state management layers. Ready for manual testing and user feedback.

**Next Steps**:
1. Conduct manual testing using checklist in `docs/testing-status.md`
2. Add edit buttons to rule and pack detail pages
3. Implement trigger create/edit form (for ad-hoc packs only)
4. Set up automated testing framework (Vitest + Playwright)
