# Sonatype Nexus IQ Management Skill

Manage and analyze Sonatype Nexus IQ applications, policy violations, vulnerabilities, and component risks.

## API Conventions

### Authentication
All API calls use Basic Auth via `Authorization: Basic $NEXUS_IQ_AUTH` -- injected automatically. Never hardcode credentials.

### Base URL
`https://$NEXUS_IQ_HOST/api/v2`

### Core Helper Function

```bash
#!/bin/bash

nexus_iq_api() {
    local method="$1"
    local endpoint="$2"
    local data="${3:-}"

    if [ -n "$data" ]; then
        curl -s -X "$method" \
            -H "Authorization: Basic $NEXUS_IQ_AUTH" \
            -H "Content-Type: application/json" \
            "https://${NEXUS_IQ_HOST}/api/v2${endpoint}" \
            -d "$data"
    else
        curl -s -X "$method" \
            -H "Authorization: Basic $NEXUS_IQ_AUTH" \
            -H "Content-Type: application/json" \
            "https://${NEXUS_IQ_HOST}/api/v2${endpoint}"
    fi
}
```

## Output Rules
- **TOKEN EFFICIENCY**: Extract only needed fields with `jq`
- Target <=50 lines per script output
- Never dump full API responses

## Discovery Phase

```bash
#!/bin/bash
echo "=== Organizations ==="
nexus_iq_api GET "/organizations" \
    | jq -r '.organizations[] | "\(.id)\t\(.name)"' | column -t | head -10

echo ""
echo "=== Applications ==="
nexus_iq_api GET "/applications" \
    | jq '{total_apps: (.applications | length)}'

echo ""
echo "=== Recent Evaluations ==="
nexus_iq_api GET "/reports/applications" \
    | jq -r '.[] | "\(.applicationId)\t\(.stage)\t\(.reportDataUrl[0:50])"' | head -10 | column -t
```

## Analysis Phase

### Policy Violations Overview

```bash
#!/bin/bash
APP_ID="${1:-}"

echo "=== Policy Violation Summary ==="
if [ -n "$APP_ID" ]; then
    REPORT=$(nexus_iq_api GET "/reports/applications/${APP_ID}" | jq -r '.[0].reportDataUrl')
    nexus_iq_api GET "$REPORT" \
        | jq '{critical: ([.components[].violations[]? | select(.policyThreatLevel >= 9)] | length), severe: ([.components[].violations[]? | select(.policyThreatLevel >= 7 and .policyThreatLevel < 9)] | length), moderate: ([.components[].violations[]? | select(.policyThreatLevel >= 4 and .policyThreatLevel < 7)] | length)}'
else
    nexus_iq_api GET "/policyViolations/crossStage" \
        | jq -r '.applicationViolations[:15][] | "\(.application.name[0:30])\tcrit:\(.criticalPolicyViolationCount)\tsevere:\(.severePolicyViolationCount)\tmod:\(.moderatePolicyViolationCount)"' | column -t
fi
```

### Vulnerable Components

```bash
#!/bin/bash
APP_ID="${1:?Application ID required}"

echo "=== Vulnerable Components ==="
REPORT=$(nexus_iq_api GET "/reports/applications/${APP_ID}" | jq -r '.[0].reportDataUrl')
nexus_iq_api GET "$REPORT" \
    | jq -r '.components[] | select(.violations | length > 0) | "\(.componentIdentifier.coordinates.artifactId // .displayName | .[0:30])\tv\(.componentIdentifier.coordinates.version // "N/A")\tviolations:\(.violations | length)\tmax_threat:\([.violations[].policyThreatLevel] | max)"' \
    | sort -t$'\t' -k4 -rn | column -t | head -20

echo ""
echo "=== License Issues ==="
nexus_iq_api GET "$REPORT" \
    | jq -r '.components[] | select(.licenseData.status == "Overridden" or .licenseData.threatCategory != null) | "\(.displayName[0:30])\t\(.licenseData.declaredLicenses[0].licenseName // "Unknown")\t\(.licenseData.status)"' \
    | head -10 | column -t
```

### Waiver Management

```bash
#!/bin/bash
echo "=== Active Waivers ==="
nexus_iq_api GET "/policyWaivers" \
    | jq -r '.[] | "\(.policyName[0:30])\t\(.componentName[0:25])\t\(.expiryTime[0:10] // "No expiry")\t\(.comment[0:30])"' \
    | column -t | head -15
```

## Output Format

Present results as a structured report:
```
Managing Sonatype Nexus Iq Report
═════════════════════════════════
Resources discovered: [count]

Resource       Status    Key Metric    Issues
──────────────────────────────────────────────
[name]         [ok/warn] [value]       [findings]

Summary: [total] resources | [ok] healthy | [warn] warnings | [crit] critical
Action Items: [list of prioritized findings]
```

Target ≤50 lines of output. Use tables for multi-resource comparisons.

## Anti-Hallucination Rules

1. **NEVER assume resource names** — always discover via CLI/API in Phase 1 before referencing in Phase 2.
2. **NEVER fabricate metric names or dimensions** — verify against the service documentation or `--help` output.
3. **NEVER mix CLI commands between service versions** — confirm which version/API you are targeting.
4. **ALWAYS use the discovery → verify → analyze chain** — every resource referenced must have been discovered first.
5. **ALWAYS handle empty results gracefully** — an empty response is valid data, not an error to retry.

## Counter-Rationalizations

| Shortcut | Counter | Why |
|----------|---------|-----|
| "I'll skip discovery and check known resources" | Always run Phase 1 discovery first | Resource names change, new resources appear — assumed names cause errors |
| "The user only asked for a quick check" | Follow the full discovery → analysis flow | Quick checks miss critical issues; structured analysis catches silent failures |
| "Default configuration is probably fine" | Audit configuration explicitly | Defaults often leave logging, security, and optimization features disabled |
| "Metrics aren't needed for this" | Always check relevant metrics when available | API/CLI responses show current state; metrics reveal trends and intermittent issues |
| "I don't have access to that" | Try the command and report the actual error | Assumed permission failures prevent useful investigation; actual errors are informative |

## Common Pitfalls

- **Two-step report access**: Get report URL from `/reports/applications/{id}`, then fetch the report data
- **Application ID vs public ID**: Internal ID (UUID) differs from public ID -- look up via `/applications`
- **Stage filtering**: Scans happen at different stages (build, stage-release, release) -- filter accordingly
- **Rate limits**: No published limits but large queries can timeout -- paginate where possible
- **Report data**: Full report JSON can be very large -- always filter with jq
