## 🆕 Final 2 Tools Implemented

### Tool 4/5: update_database_user

**CLI Command:**
```bash
datasphere dbusers update --space {space_id} --databaseuser {user_id} --file-path {temp.json}
```

**Implementation Pattern:**
- Same as create_database_user (temp file + CLI)
- Writes updated_definition to temporary JSON file
- Executes CLI command with file-path parameter
- Cleans up temp file in finally block
- 60 second timeout for slower operations

**Test Example:**
```python
update_database_user(
    space_id="SAP_CONTENT",
    database_user_id="TEST_USER",
    updated_definition={
        "consumption": {
            "consumptionWithGrant": True,  # Changed from False
            "spaceSchemaAccess": True       # Changed from False
        },
        "ingestion": {...}
    }
)
```

**Expected Result:**
- ✅ Executes real CLI command
- ✅ Updates user permissions in SAP Datasphere
- ✅ Returns CLI output with success confirmation
- ✅ Temp file automatically cleaned up

---

### Tool 5/5: delete_database_user

**CLI Command:**
```bash
datasphere dbusers delete --space {space_id} --databaseuser {user_id} [--force]
```

**Implementation Pattern:**
- Simple CLI command with optional --force flag
- Two-step confirmation workflow for safety
- Smart error detection for confirmation-required errors
- 60 second timeout

**Test Example (Step 1 - Confirmation Request):**
```python
delete_database_user(
    space_id="SAP_CONTENT",
    database_user_id="TEST_USER"
    # force not provided = confirmation requested
)
```

**Expected:** Displays warning and requests confirmation

**Test Example (Step 2 - Confirmed Deletion):**
```python
delete_database_user(
    space_id="SAP_CONTENT",
    database_user_id="TEST_USER",
    force=True  # Confirms deletion
)
```

**Expected Result:**
- ✅ Executes real CLI command with --force flag
- ✅ Permanently deletes user from SAP Datasphere
- ✅ Returns CLI output with deletion confirmation
- ⚠️ IRREVERSIBLE operation (as intended)

---

## 📊 Phase 1 Implementation Details

### Consistent Pattern Across All 5 Tools

**1. USE_MOCK_DATA Check:**
```python
if DATASPHERE_CONFIG["use_mock_data"]:
    # Mock mode - returns demo data
else:
    # Real mode - executes CLI
```

**2. CLI Execution:**
```python
result = subprocess.run(
    cmd,
    capture_output=True,
    text=True,
    check=True,
    timeout=60
)
```

**3. Error Handling:**
- `subprocess.CalledProcessError` - CLI command failed
- `FileNotFoundError` - CLI not installed
- `subprocess.TimeoutExpired` - Operation took too long
- Generic `Exception` - Catch-all

**4. Temporary File Management (create/update):**
```python
with tempfile.NamedTemporaryFile(mode='w', suffix='.json', delete=False) as temp_file:
    json.dump(user_definition, temp_file, indent=2)
    temp_file_path = temp_file.name

try:
    # Execute CLI command
    ...
finally:
    # Always cleanup
    if os.path.exists(temp_file_path):
        os.unlink(temp_file_path)
```

---

## 🔒 Security & Consent Management

All 5 tools properly integrated with authorization system:

| Tool | Permission Level | Consent Required | Risk Level |
|------|-----------------|------------------|------------|
| list_database_users | READ | No | LOW |
| create_database_user | ADMIN | Yes | HIGH |
| update_database_user | ADMIN | Yes | HIGH |
| delete_database_user | ADMIN | Yes | HIGH |
| reset_database_user_password | SENSITIVE | Yes | SENSITIVE |

**Consent Caching:** 60 minutes for HIGH/SENSITIVE operations

## 🧪 Testing Instructions for Kiro

### Test 1: update_database_user

**Prerequisites:**
- User TEST_USER must exist (created in earlier testing)
- Space SAP_CONTENT must be accessible

**Test Command:**
```python
update_database_user(
    space_id="SAP_CONTENT",
    database_user_id="TEST_USER",
    updated_definition={
        "consumption": {
            "consumptionWithGrant": True,
            "spaceSchemaAccess": True,
            "scriptServerAccess": False,
            "enablePasswordPolicy": False,
            "localSchemaAccess": False,
            "hdiGrantorForCupsAccess": False
        },
        "ingestion": {
            "auditing": {
                "dppRead": {
                    "isAuditPolicyActive": False,
                    "retentionPeriod": 7
                },
                "dppChange": {
                    "isAuditPolicyActive": False,
                    "retentionPeriod": 7
                }
            }
        }
    }
)
```

**Expected:**
1. ✅ Consent prompt displayed (ADMIN permission)
2. ✅ User grants consent
3. ✅ CLI command executes successfully
4. ✅ Returns success response with updated permissions
5. ✅ Temp file cleaned up automatically

**Validation Checklist:**
- [ ] Consent system activated
- [ ] CLI command logged in console
- [ ] No Python errors
- [ ] Success message displayed
- [ ] User permissions actually updated (verify with list_database_users)

---

### Test 2: delete_database_user (Two-Step)

**Prerequisites:**
- User TEST_USER must exist
- This is an IRREVERSIBLE operation!

**Test Step 1 - Request Confirmation:**
```python
delete_database_user(
    space_id="SAP_CONTENT",

    # no force flag
)
```

**Expected:**
1. ✅ Consent prompt displayed (ADMIN permission)
2. ✅ User grants consent
3. ✅ Confirmation warning displayed
4. ✅ Message explains consequences and asks for force=True

**Test Step 2 - Confirm Deletion:**
```python
delete_database_user(
    space_id="SAP_CONTENT",
    database_user_id="TEST_USER",
    force=True  # Confirms deletion
)
```

**Expected:**
1. ✅ CLI command executes with --force flag
2. ✅ User permanently deleted
3. ✅ Success message with IRREVERSIBLE reminder
4. ✅ User no longer appears in list_database_users

**Validation Checklist:**
- [ ] Two-step confirmation workflow works
- [ ] Consent system activated
- [ ] CLI command logged with --force flag
- [ ] No Python errors
- [ ] User actually deleted (verify with list_database_users)
- [ ] Cannot delete same user again (should error)

## 📝 Lessons Learned

### Technical Insights:
1. **Validation Bug Discovery:** Custom validators can override tool schemas - always check both layers
2. **Temp File Pattern:** Works perfectly for JSON parameter passing to CLI
3. **Force Flag Pattern:** Simple boolean to enable/disable confirmation workflow
4. **Error Detection:** Smart checking of error messages for specific keywords

### Process Insights:
1. **Incremental Testing:** Testing 3 tools before implementing final 2 was smart
2. **Validation Bug Fix:** Kiro's persistence in debugging was crucial
3. **Consistent Pattern:** Using same implementation pattern across all 5 tools made development faster
