feat(swift): voeg chat orchestration toe (E5)

Epic 5 compleet: Chat orchestration voor Swift Agenda Planning.
Alle agenda intents worden nu correct gerouteerd naar AgendaBlock
met user-friendly error handling en fallback opties.

E5.S1 - Action Routing (2 SP)
- routeIntentToArtifact() functie in action-parser
- Maps agenda intents naar juiste AgendaBlock mode
- Confidence threshold enforcement (< 0.7 → fallback)
- Required entity validation (patient voor create, identifier voor reschedule)
- Command-input gebruikt nieuwe routing ipv legacy openBlock
- Migratie naar modern artifact systeem (openArtifact)

E5.S2 - Chat Prompt Update (2 SP)
- 4 agenda intents toegevoegd aan Swift chat system prompt
- agenda_query: afspraken opvragen op datumrange
- create_appointment: nieuwe afspraak maken (required: patient, datetime)
- cancel_appointment: afspraak annuleren (disambiguation support)
- reschedule_appointment: afspraak verzetten (required: identifier)
- Entity extraction rules gedocumenteerd (dateRange, datetime, identifier)
- 4 complete voorbeelden met JSON action format
- Clarification questions voor incomplete data
- Prompt size: ~325 → ~525 regels (+60%)

E5.S3 - Error States (2 SP)
- AgendaErrorState component voor full-page errors
- AgendaErrorAlert component voor inline form errors
- getUserFriendlyMessage() vertaalt technical → user-friendly Dutch
- Auto-redirect bij auth errors (401 → /login)
- Fallback link naar /epd/agenda in alle error states
- Context-aware messaging (query/create/cancel/reschedule)
- Retry functionaliteit voor recoverable errors
- Dev-only technical details collapsible

Error message mapping:
- 401 → "Je sessie is verlopen. Log opnieuw in." + auto-redirect
- 403 → "Je hebt geen toegang tot deze afspraak."
- 404 → "De gevraagde afspraak kon niet worden gevonden."
- 500 → "Er ging iets mis op de server. Probeer het opnieuw."
- Network → "Geen internetverbinding. Controleer je netwerkverbinding."
- Timeout → "De aanvraag duurde te lang. Probeer het opnieuw."

Components updated:
- command-input: gebruikt routeIntentToArtifact + openArtifact
- agenda-create-form: gebruikt AgendaErrorAlert met fallback link
- chat/route: uitgebreide system prompt met agenda sectie

Nieuwe files:
- lib/swift/action-parser.ts: routeIntentToArtifact() functie
- components/swift/artifacts/blocks/agenda-error-state.tsx (225 regels)
- docs/swift/implementation-e5-s1-action-routing.md
- docs/swift/implementation-e5-s2-chat-prompt.md
- docs/swift/implementation-e5-s3-error-states.md

Documentatie:
- Bouwplan bijgewerkt: Epic 5 → Done
- 3 implementation docs met API specs en testing scenarios
- Error handling best practices gedocumenteerd

Progress: 48 SP / 51 SP (94%) - Epic 6 (QA) remaining

# Epic 5.S1 Implementation: Action Routing
**Story**: E5.S1 - Action routing
**Date**: 2025-12-27
**Status**: ✅ Complete
**Story Points**: 2 SP
---
## 🎯 Objective
Implement intent routing logic that maps agenda intents to the AgendaBlock artifact with the appropriate mode and prefill data.
---
## 📝 Implementation Summary
### 1. Updated Action Parser Schemas
**File**: `lib/swift/action-parser.ts`
Added agenda intents to validation schemas:
- `agenda_query`
- `create_appointment`
- `cancel_appointment`
- `reschedule_appointment`
### 2. Created Intent Routing Function
**Function**: `routeIntentToArtifact(intent, entities, confidence)`
**Purpose**: Maps intents to artifact configurations with:
- Artifact type
- Title
- Prefill data
**Logic**:
```typescript
if (confidence < 0.7) return null; // Trigger fallback
switch (intent) {
case 'agenda_query':
return { type: 'agenda_query', title: 'Agenda', prefill: { dateRange } };
case 'create_appointment':
if (!patientName && !patientId) return null; // Missing required entity
return { type: 'create_appointment', title: 'Nieuwe afspraak', prefill: {...} };
case 'cancel_appointment':
return { type: 'cancel_appointment', title: 'Afspraak annuleren', prefill: {...} };
case 'reschedule_appointment':
if (!identifier) return null; // Need to know which appointment
return { type: 'reschedule_appointment', title: 'Afspraak verzetten', prefill: {...} };
// ... other intents (dagnotitie, zoeken, overdracht)
}
```
**Key Features**:
- ✅ Confidence threshold (0.7) enforcement
- ✅ Required entity validation (patient for create, identifier for reschedule)
- ✅ Returns null to trigger clarification when needed
- ✅ Proper prefill data extraction for each intent
### 3. Updated Command Input
**File**: `components/swift/command-center/command-input.tsx`
**Changes**:
1. Import `routeIntentToArtifact` from action-parser
2. Add `openArtifact` to store hooks
3. Replace legacy `openBlock` logic with routing:
```typescript
// OLD (direct block opening):
if (intent !== 'unknown' && confidence >= 0.5) {
openBlock(intent as BlockType, entities);
}
// NEW (routing with artifact system):
const artifactConfig = routeIntentToArtifact(intent, entities, confidence);
if (artifactConfig) {
openArtifact({
type: artifactConfig.type,
title: artifactConfig.title,
prefill: artifactConfig.prefill,
});
}
```
---
## 🔑 Key Routing Rules
| Intent | Artifact Type | Required Entities | Mode |
|--------|---------------|-------------------|------|
| `agenda_query` | `agenda_query` | None | List view with date filter |
| `create_appointment` | `create_appointment` | `patientName` OR `patientId` | Create form |
| `cancel_appointment` | `cancel_appointment` | None | Cancel view (may need disambiguation) |
| `reschedule_appointment` | `reschedule_appointment` | `identifier` | Reschedule form |
---
## 📊 Confidence Thresholds
| Confidence | Action | Example |
|------------|--------|---------|
| **≥ 0.7** | Open artifact directly | "afspraken vandaag" → AgendaBlock opens |
| **< 0.7** | Show fallback picker | Low confidence → User chooses intent manually |
| **Missing required entity** | Show fallback picker | "maak afspraak" (no patient) → Clarification needed |
---
## 🔄 Data Flow
```
User Input
Intent Classification API (/api/intent/classify)
{ intent, entities, confidence }
routeIntentToArtifact()
Artifact Config { type, title, prefill } OR null
openArtifact() OR openBlock('fallback')
AgendaBlock renders with prefilled data
```
---
## 📁 Files Modified
```
lib/swift/action-parser.ts
├── Updated ActionSchema with agenda intents
├── Updated artifact type enum
├── Added routeIntentToArtifact() function
└── Updated validateArtifactType() for agenda intents
components/swift/command-center/command-input.tsx
├── Import routeIntentToArtifact
├── Use openArtifact from store
└── Replace direct block opening with routing logic
```
---
## ✅ Acceptance Criteria
| Criterion | Status | Notes |
|-----------|--------|-------|
| Agenda intents open AgendaBlock | ✅ | Via routing function |
| Correct mode selected | ✅ | Based on intent type |
| Prefill data passed correctly | ✅ | Mapped from entities |
| Confidence threshold enforced | ✅ | < 0.7 shows fallback |
| Required entities validated | ✅ | Returns null when missing |
| TypeScript type safety | ✅ | No compilation errors |
---
## 🧪 Testing Scenarios
### Scenario 1: High Confidence Agenda Query
**Input**: "afspraken vandaag"
**Expected**:
- Intent: `agenda_query`
- Confidence: ~0.95
- Result: AgendaBlock opens in list mode with today's date range
### Scenario 2: Create Appointment with Patient
**Input**: "maak afspraak jan morgen 14:00"
**Expected**:
- Intent: `create_appointment`
- Entities: `{ patientName: "jan", datetime: {...} }`
- Result: AgendaBlock opens in create mode with prefilled patient and time
### Scenario 3: Create Appointment without Patient (Missing Entity)
**Input**: "maak afspraak morgen 14:00"
**Expected**:
- Intent: `create_appointment`
- Entities: `{ datetime: {...} }` (no patient)
- Result: FallbackPicker opens (routing returns null due to missing required entity)
### Scenario 4: Low Confidence
**Input**: "agenda ding morgen"
**Expected**:
- Intent: `agenda_query` (maybe)
- Confidence: < 0.7
- Result: FallbackPicker opens (routing returns null due to low confidence)
### Scenario 5: Reschedule with Identifier
**Input**: "verzet 14:00 naar 15:00"
**Expected**:
- Intent: `reschedule_appointment`
- Entities: `{ identifier: {...}, newDatetime: {...} }`
- Result: AgendaBlock opens in reschedule mode
---
## 🚀 Next Steps
1. **E5.S2**: Update chat API prompt to include agenda intent examples
2. **E5.S3**: Add error state handling with fallback links
3. **E6**: Manual QA testing of complete agenda flow
---
## 💡 Lessons Learned
1. **Artifact System**: Modern approach using `openArtifact()` is cleaner than legacy `openBlock()`
2. **Centralized Routing**: Single function makes intent mapping maintainable and testable
3. **Validation Early**: Checking required entities in routing prevents incomplete forms
4. **Confidence Thresholds**: 0.7 threshold balances automation with user control
5. **Type Safety**: TypeScript schemas ensure consistency across intent types
---
**Implementation Status**: ✅ Complete
**Ready for**: E5.S2 (Chat prompt update)
**Estimated Testing Time**: 15-20 minutes (manual testing with various inputs)

# Epic 5.S2 Implementation: Chat Prompt Update
**Story**: E5.S2 - Chat prompt update
**Date**: 2025-12-27
**Status**: ✅ Complete
**Story Points**: 2 SP
---
## 🎯 Objective
Update the Swift chat API system prompt to include agenda intent descriptions, entity extraction rules, and action format examples.
---
## 📝 Implementation Summary
### File Modified
**`app/api/swift/chat/route.ts`** - Function: `buildMedicalScribePrompt()`
### Changes Made
#### 1. Added Agenda Intents to P2 Section
Added 4 new agenda intents to the P2 (belangrijk, middenfrequent) section:
**agenda_query** - Afspraken opvragen
- Triggers: "afspraken vandaag", "agenda morgen", "wat is mijn volgende afspraak", "afspraken deze week"
- Entities: `dateRange` (vandaag/morgen/deze week/volgende week)
- Action: Toon lijst van afspraken in AgendaBlock
**create_appointment** - Nieuwe afspraak maken
- Triggers: "maak afspraak [patient]", "plan intake [patient]", "afspraak maken met [patient] [datum] [tijd]"
- Entities: `patientName`, `datetime`, `appointmentType`, `location`
- Required: `patientName` OR `patientId`, `datetime`
- Optional: `appointmentType` (default: behandeling), `location` (default: praktijk)
- Action: Open create form met pre-fill
**cancel_appointment** - Afspraak annuleren
- Triggers: "annuleer afspraak [patient]", "cancel [tijd]", "afspraak van [patient] annuleren"
- Entities: `identifier` (patient naam/tijd combinatie voor matching)
- Action: Toon confirmation dialog, bij meerdere matches: disambiguation
**reschedule_appointment** - Afspraak verzetten
- Triggers: "verzet afspraak [patient]", "verzet [oude tijd] naar [nieuwe tijd]", "[patient] naar [nieuwe datum]"
- Entities: `identifier`, `newDatetime`
- Required: `identifier`
- Action: Toon edit form met oude en nieuwe tijd
#### 2. Extended Clarification Questions
Added agenda-specific clarification examples:
- "Voor welke datum wil je de afspraak maken?" (datum ontbreekt bij create_appointment)
- "Op welk tijdstip?" (tijd ontbreekt bij create_appointment)
- "Welke afspraak wil je verzetten?" (identifier onduidelijk bij reschedule/cancel)
#### 3. Added Agenda Examples
**Voorbeeld 5: Agenda query**
```json
{
"type": "action",
"intent": "agenda_query",
"entities": {
"dateRange": {
"start": "2025-12-27",
"end": "2025-12-27",
"label": "vandaag"
}
},
"confidence": 0.98,
"artifact": {
"type": "agenda_query",
"prefill": {
"dateRange": {...}
}
}
}
```
**Voorbeeld 6: Afspraak maken (compleet)**
```json
{
"type": "action",
"intent": "create_appointment",
"entities": {
"patientName": "Jan",
"datetime": {
"date": "2025-12-28",
"time": "14:00"
},
"appointmentType": "behandeling",
"location": "praktijk"
},
"confidence": 0.95,
"artifact": {
"type": "create_appointment",
"prefill": {...}
}
}
```
**Voorbeeld 7: Afspraak maken (incompleet)**
User: "Plan intake Marie"
Response: "Voor welke datum en tijd wil je de intake voor Marie plannen?"
(Geen JSON action omdat datetime ontbreekt)
**Voorbeeld 8: Afspraak verzetten**
```json
{
"type": "action",
"intent": "reschedule_appointment",
"entities": {
"identifier": {
"type": "time",
"time": "14:00"
},
"newDatetime": {
"date": "2025-12-27",
"time": "15:00"
}
},
"confidence": 0.92,
"artifact": {
"type": "reschedule_appointment",
"prefill": {...}
}
}
```
---

## 🧪 Testing Scenarios
### Scenario 1: Agenda Query - High Confidence
**Input**: "afspraken vandaag"
**Expected Claude Response**:
- Text: "Ik toon je de afspraken voor vandaag."
- JSON: `{ intent: "agenda_query", confidence: 0.98, entities: { dateRange: {...} } }`
### Scenario 2: Create Appointment - Complete
**Input**: "maak afspraak met Jan morgen 14:00"
**Expected Claude Response**:
- Text: "Ik maak een afspraak voor Jan morgen om 14:00."
- JSON: `{ intent: "create_appointment", confidence: 0.95, entities: { patientName, datetime } }`
### Scenario 3: Create Appointment - Incomplete
**Input**: "plan intake Marie"
**Expected Claude Response**:
- Text: "Voor welke datum en tijd wil je de intake voor Marie plannen?"
- JSON: None (confidence < 0.7 due to missing datetime)
### Scenario 4: Reschedule - Time Based
**Input**: "verzet 14:00 naar 15:00"
**Expected Claude Response**:
- Text: "Ik verzet de afspraak van 14:00 naar 15:00."
- JSON: `{ intent: "reschedule_appointment", confidence: 0.92, entities: { identifier, newDatetime } }`
### Scenario 5: Cancel - Patient Based
**Input**: "annuleer afspraak Jan"
**Expected Claude Response**:
- Text: Confirmation or disambiguation if multiple Jans
- JSON: `{ intent: "cancel_appointment", entities: { identifier: { type: "patient", patientName: "Jan" } } }`
---
## 🎯 Prompt Engineering Techniques Used
1. **Clear Intent Definitions**: Each intent has triggers, entities, and actions clearly defined
2. **Required/Optional Distinction**: Helps Claude decide when to ask clarification questions
3. **Confidence Guidance**: Thresholds guide when to open artifacts vs ask questions
4. **Concrete Examples**: 4 full examples with expected JSON structure
5. **Error Cases**: Example 7 shows incomplete input handling
6. **Entity Templates**: JSON structures show exact format expected
7. **Natural Language Triggers**: Multiple trigger phrases per intent
---
## 💡 Design Decisions
### Why P2 Instead of P1?
Agenda management is important but not as critical/frequent as dagnotitie (P1). Healthcare workers make notes constantly but schedule appointments less frequently.
### Why Include Defaults?
- `appointmentType`: "behandeling" (most common case)
- `location`: "praktijk" (most common location)
This reduces friction - users don't need to specify every detail.
### Why identifier Instead of encounterId?
The `identifier` structure allows flexible matching:
- By patient name: "annuleer afspraak Jan"
- By time: "cancel 14:00"
- By combination: "verzet Jan's afspraak"
The backend (Epic 3 API + Epic 4 UI) handles the disambiguation.
### Why Separate Examples for Complete/Incomplete?
Shows Claude two paths:
1. Complete data → Generate action (Example 6)
2. Incomplete data → Ask question (Example 7)
This demonstrates the confidence threshold logic clearly.
---
## 🚀 Next Steps
**E5.S3** - Error states
- Add error handling for API failures
- Add fallback links to `/epd/agenda`
- Handle offline/network errors gracefully

# Epic 5.S3 Implementation: Error States
**Story**: E5.S3 - Error states
**Date**: 2025-12-27
**Status**: ✅ Complete
**Story Points**: 2 SP
---
## 🎯 Objective
Add user-friendly error states to agenda functionality with fallback links to `/epd/agenda` and proper error messaging in Dutch.
---
## 📝 Implementation Summary
### New Component Created
**`components/swift/artifacts/blocks/agenda-error-state.tsx`**
Created two reusable error components for consistent error handling across all agenda views:
1. **AgendaErrorState** - Full-page error state with retry button
2. **AgendaErrorAlert** - Inline error alert for forms
### Updated Components
**`components/swift/artifacts/blocks/agenda-create-form.tsx`**
- Replaced basic error display with `AgendaErrorAlert`
- Added fallback link to full agenda
- Added dismiss functionality
---
## 🔑 Key Features
### 1. User-Friendly Error Messages
The `getUserFriendlyMessage()` function maps technical errors to Dutch user-facing messages:
| Error Type | Technical | User Message |
|------------|-----------|--------------|
| **Auth (401)** | "401 Unauthorized" | "Je sessie is verlopen. Log opnieuw in." |
| **Not Found (404)** | "404 Not Found" | "De gevraagde afspraak kon niet worden gevonden." |
| **Forbidden (403)** | "403 Forbidden" | "Je hebt geen toegang tot deze afspraak." |
| **Server (500)** | "500 Internal Server Error" | "Er ging iets mis op de server. Probeer het opnieuw." |
| **Network** | "Failed to fetch" | "Geen internetverbinding. Controleer je netwerkverbinding." |
| **Timeout** | "Request timeout" | "De aanvraag duurde te lang. Probeer het opnieuw." |
### 2. Context-Aware Messages
Different default messages based on operation context:
```typescript
context: 'query' "Er ging iets mis bij het ophalen van je afspraken."
context: 'create' "Er ging iets mis bij het aanmaken van de afspraak."
context: 'cancel' "Er ging iets mis bij het annuleren van de afspraak."
context: 'reschedule' "Er ging iets mis bij het verzetten van de afspraak."
```
### 3. Fallback Link to Full Agenda
All error states include a prominent link to `/epd/agenda`:
```tsx
<Button onClick={() => window.location.href = '/epd/agenda'}>
<ExternalLink className="h-4 w-4" />
Open volledige agenda
</Button>
```
### 4. Automatic Auth Redirect
Auth errors (401) automatically redirect to `/login`:
```typescript
if (isAuthError) {
window.location.href = '/login';
return null;
}
```
### 5. Retry Functionality
Optional retry button for recoverable errors:
```tsx
<AgendaErrorState
error={error}
onRetry={() => fetchAppointments()}
showFallbackLink={true}
context="query"
/>
```
### 6. Dev-Only Technical Details
In development mode, shows collapsible technical details:
```tsx
{process.env.NODE_ENV === 'development' && (
<details>
<summary>Technische details (dev only)</summary>
<pre>{error.stack}</pre>
</details>
)}
```
---
## 📐 Component API
### AgendaErrorState (Full-Page Error)
```typescript
interface AgendaErrorStateProps {
error: string | Error; // Error to display
onRetry?: () => void; // Optional retry function
showFallbackLink?: boolean; // Show link to /epd/agenda (default: true)
context?: 'query' | 'create' | 'cancel' | 'reschedule';
}
```
**Usage Example**:
```tsx
<AgendaErrorState
error="Failed to fetch appointments"
onRetry={() => refetch()}
context="query"
/>
```
### AgendaErrorAlert (Inline Alert)
```typescript
interface AgendaErrorAlertProps {
error: string | Error; // Error to display
onDismiss?: () => void; // Optional dismiss function
showFallbackLink?: boolean; // Show link to /epd/agenda (default: false)
}
```
**Usage Example**:
```tsx
{error && (
<AgendaErrorAlert
error={error}
onDismiss={() => setError(null)}
showFallbackLink={true}
/>
)}
```

---
## 💡 Design Decisions
### Why Two Components?
1. **AgendaErrorState**: For full-page failures (query, list loading)
2. **AgendaErrorAlert**: For form-level errors (create, cancel, reschedule)
Different UI patterns for different contexts.
### Why Auto-Redirect for Auth Errors?
Auth errors (401) are not user-recoverable in the UI. User must log in again, so immediate redirect provides better UX than showing an error message.
### Why Show Fallback Link?
If Swift fails, users can always fall back to the classic agenda UI at `/epd/agenda`. This provides a safety net and reduces frustration.
### Why Context Parameter?
Different operations have different error messages. Context makes messages more specific and actionable:
- Query failure → "bij het ophalen"
- Create failure → "bij het aanmaken"
- etc.
### Why Dev-Only Technical Details?
Technical stack traces are only useful for developers debugging issues. Production users should see user-friendly messages only.

## 🚀 Error Handling Best Practices
### 1. Always Use getUserFriendlyMessage()
```typescript
// ❌ Bad - Technical error exposed to user
setError(error.message);
// ✅ Good - User-friendly Dutch message
const friendlyMessage = getUserFriendlyMessage(error, 'create');
setError(friendlyMessage);
```
### 2. Provide Context
```typescript
// ❌ Bad - Generic error
<AgendaErrorState error={error} />
// ✅ Good - Context-specific error
<AgendaErrorState error={error} context="query" />
```
### 3. Offer Retry When Possible
```typescript
// ❌ Bad - No recovery path
<AgendaErrorState error={error} />
// ✅ Good - User can retry
<AgendaErrorState
error={error}
onRetry={() => refetchAppointments()}
/>
```
### 4. Use Inline Alerts for Forms
```typescript
// ❌ Bad - Full-page error for form validation
<AgendaErrorState error="Patient required" />
// ✅ Good - Inline alert in form
<AgendaErrorAlert
error="Selecteer a.u.b. een patiënt."
onDismiss={() => setError(null)}
/>
```
