Tasks Spec Update

Specification Update Workflow

When to Use This Skill

• Syncing specs with implementation
• Branch comparison analysis
• Post-implementation documentation update
• Feature spec verification

Pre-Flight Checklist

• Identify specification files to update
• Determine implementation changes
• Compare current state vs documented state
• Plan update strategy

Phase 1: Change Discovery

Git-Based Discovery

# Compare branches
git diff main..feature-branch --name-only

# Get detailed diff
git diff main..feature-branch

# List commits with messages
git log main..feature-branch --oneline

# Find files changed since date
git log --since="2024-01-01" --name-only --oneline

Pattern-Based Discovery

# Find all spec files
find . -name "*.spec.md" -o -name "*-specification.md"

# Find implementation files
grep -r "class.*Command" --include="*.cs" -l

# Cross-reference
grep -r "SaveEmployee" --include="*.md"  # In specs
grep -r "SaveEmployee" --include="*.cs"  # In code

Phase 2: Gap Analysis

Create Analysis Document

# Specification Gap Analysis

## Date: [Date]
## Feature: [Feature Name]

## Implementation Status

| Component | Specified | Implemented | Gap |
|-----------|-----------|-------------|-----|
| Entity: Employee | ✅ | ✅ | None |
| Command: SaveEmployee | ✅ | ✅ | Missing validation doc |
| Query: GetEmployeeList | ✅ | ✅ | Filters not documented |
| Event: OnEmployeeCreated | ❌ | ✅ | Not in spec |

## New Implementations (Not in Spec)
1. `BulkUpdateEmployeeCommand` - Added in PR #123
2. `EmployeeExportQuery` - Added for reporting

## Spec Items Not Implemented
1. `EmployeeArchiveCommand` - Deferred to Phase 2
2. `EmployeeAuditTrail` - Pending requirements

## Documentation Updates Needed
1. Add BulkUpdateEmployeeCommand to spec
2. Document new query filters
3. Add event handler documentation

Phase 3: Specification Update

Pattern 1: Entity Specification Update

# Employee Entity Specification

## Properties

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| Id | string | Yes | Unique identifier (ULID) |
| FullName | string | Yes | Employee full name (max 200) |
| Email | string | Yes | Email address (unique per company) |
| Status | EmployeeStatus | Yes | Current employment status |
| PhoneNumber | string | No | Contact phone (NEW in v2.1) |

## Computed Properties

| Property | Calculation |
|----------|-------------|
| IsActive | Status == Active && !IsDeleted |
| DisplayName | `{Code} - {FullName}` |

## Validation Rules

1. FullName: Required, max 200 characters
2. Email: Required, valid email format, unique within company
3. PhoneNumber: Optional, valid phone format (NEW in v2.1)

## Static Expressions

| Expression | Purpose |
|------------|---------|
| UniqueExpr(companyId, userId) | Find unique employee |
| ActiveInCompanyExpr(companyId) | Filter active employees |
| SearchExpr(term) | Full-text search |

Pattern 2: Command Specification Update

# SaveEmployeeCommand Specification

## Overview
Creates or updates an employee record.

## Request

```json
{
  "id": "string | null",
  "fullName": "string",
  "email": "string",
  "status": "Active | Inactive | Terminated",
  "phoneNumber": "string | null"
}

Validation

Response

{
  "employee": {
    "id": "string",
    "fullName": "string",
    "email": "string",
    "status": "string"
  }
}

Side Effects

1. Entity Event: PlatformCqrsEntityEvent<Employee> raised
2. Cross-Service Sync: Employee synced to other services
3. Notification: Welcome email sent (create only)

Error Codes

## Pattern 3: API Endpoint Specification

```markdown
# Employee API Endpoints

## Base URL
`/api/Employee`

## Endpoints

### GET /api/Employee
List employees with filtering and pagination.

**Query Parameters**
| Parameter | Type | Description |
|-----------|------|-------------|
| searchText | string | Full-text search |
| statuses | array | Filter by status |
| skipCount | int | Pagination offset |
| maxResultCount | int | Page size (max 100) |

**Response**
```json
{
  "items": [...],
  "totalCount": 100
}

POST /api/Employee

Create or update employee.

Request Body See SaveEmployeeCommand specification.

DELETE /api/Employee/{id}

Soft delete an employee.

Path Parameters

Response: 204 No Content

Authentication

All endpoints require authentication. Use Authorization: Bearer {token} header.

Authorization

## Phase 4: Verification

### Cross-Reference Check
```bash
# Verify all commands are documented
for cmd in $(grep -r "class.*Command" --include="*.cs" -l); do
  name=$(grep -o "class [A-Za-z]*Command" "$cmd" | head -1)
  if ! grep -q "$name" docs/specifications/*.md; then
    echo "Missing in spec: $name"
  fi
done
