- Extract 9 skill files from command knowledge:
  - mcp-tools-reference.md: Complete NetBox MCP tools reference
  - system-discovery.md: Bash commands for system info gathering
  - device-registration.md: Device registration workflow
  - sync-workflow.md: Machine sync process

Change Audit Skill

Audit NetBox changes for tracking and compliance.

Prerequisites

Load skill: mcp-tools-reference

MCP Tools

Tool	Purpose	Parameters
`extras_list_object_changes`	List changes	`user_id`, `changed_object_type`, `action`
`extras_get_object_change`	Get change details	`id`

Common Object Types

Category	Object Types
DCIM	`dcim.device`, `dcim.interface`, `dcim.site`, `dcim.rack`, `dcim.cable`
IPAM	`ipam.ipaddress`, `ipam.prefix`, `ipam.vlan`, `ipam.vrf`
Virtualization	`virtualization.virtualmachine`, `virtualization.cluster`
Tenancy	`tenancy.tenant`, `tenancy.contact`

Audit Workflow

Parse user request - Determine filters
Query object changes - extras_list_object_changes
Enrich data - Fetch detailed records if needed
Analyze patterns - Identify bulk operations, unusual activity
Generate report - Structured format

## NetBox Change Audit Report

**Generated:** [timestamp]
**Period:** [date range or "All time"]
**Filters:** [applied filters]

### Summary

| Metric | Count |
|--------|-------|
| Total Changes | X |
| Creates | Y |
| Updates | Z |
| Deletes | W |
| Unique Users | N |
| Object Types | M |

### Changes by Action

#### Created Objects (Y)

| Time | User | Object Type | Object | Details |
|------|------|-------------|--------|---------|
| 2024-01-15 14:30 | admin | dcim.device | server-01 | Created device |

#### Updated Objects (Z)

| Time | User | Object Type | Object | Changed Fields |
|------|------|-------------|--------|----------------|
| 2024-01-15 15:00 | john | ipam.ipaddress | 10.0.1.50/24 | status, description |

#### Deleted Objects (W)

| Time | User | Object Type | Object | Details |
|------|------|-------------|--------|---------|
| 2024-01-14 09:00 | admin | dcim.interface | eth2 | Removed from server-01 |

### Changes by User

| User | Creates | Updates | Deletes | Total |
|------|---------|---------|---------|-------|
| admin | 5 | 10 | 2 | 17 |
| john | 3 | 8 | 0 | 11 |

### Changes by Object Type

| Object Type | Creates | Updates | Deletes | Total |
|-------------|---------|---------|---------|-------|
| dcim.device | 2 | 5 | 0 | 7 |
| ipam.ipaddress | 4 | 3 | 1 | 8 |

### Timeline

2024-01-15: ######## 8 changes 2024-01-14: #### 4 changes 2024-01-13: ## 2 changes


### Notable Patterns

- **Bulk operations:** [Many changes in short time]
- **Unusual activity:** [Unexpected deletions, after-hours changes]
- **Missing audit trail:** [Expected changes not logged]

### Recommendations

1. [Security or process recommendations based on findings]

Enriching Change Details

For detailed audit, use extras_get_object_change to see:

prechange_data - Object state before change
postchange_data - Object state after change
request_id - Links related changes in same request

Security Audit Mode

When user asks for "security audit" or "compliance report":

Focus on deletions and permission-sensitive changes
Highlight changes to critical objects (firewalls, VRFs, prefixes)
Flag changes outside business hours
Identify users with high change counts

Filter Examples

Request	Filter
Recent changes	None (last 24 hours default)
Last 7 days	Filter by `time` field
By user	`user_id=<id>`
Device changes	`changed_object_type=dcim.device`
All deletions	`action=delete`
