# Trigger and Execution UI Enhancements

**Date:** 2024-01-27  
**Status:** Complete

## Summary

This session implemented several UI improvements focused on triggers and executions:
1. Unified pack prefix input styling for rule reference fields
2. Complete ad-hoc trigger creation functionality
3. Trigger enable/disable toggle switch
4. Deletion protection for pack-deployed triggers
5. Status filter for execution history page

## Changes Made

### 1. Unified Pack Prefix Input Styling

#### Problem
The rule creation form had two separate, distinct fields for the pack reference and local reference, making the input experience disjointed.

#### Solution
Created a unified input component where the pack prefix appears as part of the input field but is non-editable.

#### Files Changed
- `attune/web/src/index.css` - Added `.input-with-prefix` component class
  ```css
  .input-with-prefix {
    display: flex with prefix span and input
    prefix: gray background, non-editable
    input: seamlessly connected with shared border
  }
  ```

- `attune/web/src/components/forms/RuleForm.tsx` - Updated reference field to use unified styling
  - Pack prefix (`core.`) appears inside field with gray background
  - Local ref portion is editable
  - Error states apply to both prefix and input
  - No visible gap between components

#### Visual Result
```
┌─────────┬───────────────────────────┐
│ core.   │ my_rule_name              │
│ (gray)  │ (editable white)          │
└─────────┴───────────────────────────┘
```

### 2. Ad-hoc Trigger Creation

#### New Components

**`attune/web/src/components/forms/TriggerForm.tsx` (414 lines)**
- Complete form for creating/editing triggers
- **Label-first pattern:** Label field before ref with auto-population
- **Unified pack prefix input:** Uses `.input-with-prefix` styling
- Fields:
  - Pack selection (required, disabled when editing)
  - Label and reference with auto-population
  - Description (optional)
  - Parameter schema (JSON, optional)
  - Output schema (JSON, optional)  
  - Webhook enabled toggle
  - Enabled/disabled toggle
- JSON validation for schemas
- Full error handling and field validation
- Reference format validation (lowercase, numbers, underscores only)

**`attune/web/src/pages/triggers/TriggerCreatePage.tsx` (45 lines)**
- Dedicated page for trigger creation
- Informational content explaining:
  - Ad-hoc trigger use cases
  - Webhook functionality
  - Workflow event types
  - Schema validation benefits
- Breadcrumb navigation back to triggers list

#### Updated Components

**`attune/web/src/pages/triggers/TriggersPage.tsx`**
- Added "Create Trigger" button with Plus icon in header
- Button positioned next to page title for discoverability
- Links to `/triggers/create` route

**`attune/web/src/App.tsx`**
- Added route: `/triggers/create` → `TriggerCreatePage`
- Positioned before dynamic `:ref` route for proper matching

#### Utility Enhancements

**`attune/web/src/lib/format-utils.ts`**
- Enhanced `extractLocalRef(fullRef, packRef?)` 
  - Now accepts optional `packRef` parameter
  - Explicitly removes pack prefix when provided
  - Falls back to last-dot extraction
- Added `combinePackLocalRef(packRef, localRef)` alias
  - Consistent naming across form components
  - Wraps existing `combineRefs()` function

**`attune/web/tsconfig.app.json`**
- Added exclusion for test files: `src/**/*.test.ts`, `src/**/*.test.tsx`
- Prevents compilation errors from test-only dependencies

### 3. Trigger Enable/Disable Toggle

#### Problem
Triggers could only be managed by deletion, with no way to temporarily disable them like rules.

#### Solution
Implemented toggle switch matching the rules page design.

#### Files Changed

**`attune/web/src/hooks/useTriggers.ts`**
- Added `useEnableTrigger()` mutation hook
- Added `useDisableTrigger()` mutation hook
- Both hooks invalidate queries on success for immediate UI updates

**`attune/web/src/pages/triggers/TriggersPage.tsx`**
- Added toggle switch to trigger detail header
- Switch appears next to trigger title
- Visual feedback during toggle operation ("Updating...")
