# Config Monitoring — PAI Integration

**Version**: v1.2.3 | **Status**: Active | **Last Updated**: March 2026

## AI Capabilities

The `config_monitoring` module enables AI agents to track configuration file changes, detect environment drift, audit compliance, and perform hot-reload watching. This provides the foundational configuration awareness layer for the Personal AI Infrastructure.

## Algorithm Phase Mapping

| PAI Phase | Relevance | Tools Used | Description |
| :--- | :--- | :--- | :--- |
| **OBSERVE** (1/7) | Primary | `config_monitoring_detect_changes` | Detect configuration mutations across environments |
| **THINK** (2/7) | Secondary | `config_monitoring_summary` | Assess monitoring state to inform decisions |
| **BUILD** (4/7) | Secondary | — | No direct build-phase tools |
| **EXECUTE** (5/7) | Primary | `config_monitoring_detect_changes` | Verify configuration state before/after deployments |
| **VERIFY** (6/7) | Primary | `config_monitoring_hash_file`, drift detection | Validate configuration integrity and compliance |
| **LEARN** (7/7) | Secondary | `config_monitoring_summary` | Track configuration change patterns over time |

## MCP Tools

| Tool | Category | Trust Level | Description |
| :--- | :--- | :--- | :--- |
| `config_monitoring_detect_changes` | Monitoring | Safe | Detect config file changes by comparing SHA-256 hashes to baselines |
| `config_monitoring_summary` | Monitoring | Safe | Get aggregate monitoring state (snapshots, changes, audits) |
| `config_monitoring_hash_file` | Utility | Safe | Compute SHA-256 hash of a single configuration file |

## Agent Role Access

| Agent Role | Access Level | Permitted Operations |
| :--- | :--- | :--- |
| Engineer | Full | Change detection, snapshot creation, drift analysis, auditing, hot-reload |
| Architect | Read | Monitoring summary, audit history review, drift analysis |
| QATester | Read + Execute | Change detection, compliance auditing |
| Operator | Full | All monitoring and auditing operations |

## Integration Patterns

### Configuration Gate

Agents can use change detection as a gate before deployments:

```python
from codomyrmex.config_monitoring import ConfigurationMonitor

monitor = ConfigurationMonitor()
changes = monitor.detect_config_changes(["/etc/app/config.yaml"])
if changes:
    # Alert operator or block deployment
    pass
```

### Continuous Compliance

Schedule periodic `audit_configuration` calls to maintain compliance posture:

```python
audit = monitor.audit_configuration("production", "/etc/app/")
if audit.compliance_status == "non_compliant":
    for issue in audit.issues_found:
        # Route to remediation workflow
        pass
```

## Dependencies

- **Foundation**: `logging_monitoring` (structured logging), `model_context_protocol` (`@mcp_tool` decorator)
- **Foundation**: `exceptions` (`CodomyrmexError`)
- **Standard Library**: `hashlib`, `json`, `threading`, `pathlib`, `re`
