CloudHealth Management Skill

Manage multi-cloud cost reporting, governance, and optimization with CloudHealth.

MANDATORY: Discovery-First Pattern

Always list accounts and perspectives before querying cost data.

Phase 1: Discovery

#!/bin/bash

cht_api() {
    local endpoint="$1"
    curl -s -H "Content-Type: application/json" \
        "https://chapi.cloudhealthtech.com/v1/${endpoint}?api_key=${CLOUDHEALTH_API_KEY}"
}

echo "=== CloudHealth Accounts ==="
cht_api "aws_accounts" | jq -r '
    .aws_accounts[] | "\(.id)\t\(.name)\t\(.status)\t\(.owner_id)"
' | column -t | head -20

echo ""
echo "=== Perspectives ==="
cht_api "perspective_schemas" | jq -r '.[] | "\(.id)\t\(.name)"' | column -t | head -15

echo ""
echo "=== Current Month Spend ==="
cht_api "olap_reports/cost/history" | jq -r '
    .dimensions[0].items[] | "\(.label)\t$\(.total | . * 100 | round / 100)"
' | sort -t'$' -k2 -rn | head -10

Core Helper Functions

#!/bin/bash

cht_api() {
    local endpoint="$1"
    local params="${2:-}"
    curl -s -H "Content-Type: application/json" \
        "https://chapi.cloudhealthtech.com/v1/${endpoint}?api_key=${CLOUDHEALTH_API_KEY}${params:+&$params}"
}

cht_report() {
    local report_type="$1"
    local params="${2:-}"
    cht_api "olap_reports/${report_type}" "$params"
}

Output Rules

• TOKEN EFFICIENCY: Target ≤50 lines per output
• Use jq to extract cost summaries from OLAP report responses
• Round dollar amounts to 2 decimal places

Common Operations

Cost Reporting by Account

#!/bin/bash
MONTHS="${1:-3}"

echo "=== Monthly Cost Trend (last $MONTHS months) ==="
cht_api "olap_reports/cost/history" "interval=monthly&past=${MONTHS}" | jq -r '
    .dimensions[0].items[] |
    "\(.label)\t$\(.values | map(. // 0) | map(. * 100 | round / 100) | join("\t$"))"
' | column -t | head -20

echo ""
echo "=== Cost by Service ==="
cht_api "olap_reports/cost/history" "interval=monthly&past=1&dimensions[]=AWS-Service-Category" | jq -r '
    .dimensions[0].items[] |
    "\(.label)\t$\(.total | . * 100 | round / 100)"
' | sort -t'$' -k2 -rn | column -t | head -15

Rightsizing Recommendations

#!/bin/bash
echo "=== EC2 Rightsizing Recommendations ==="
cht_api "olap_reports/usage/ec2_instance" | jq -r '
    .dimensions[0].items[] |
    select(.recommendation != null) |
    "\(.label)\tCurrent: \(.instance_type)\tRecommended: \(.recommendation.instance_type)\tSavings: $\(.recommendation.savings | . * 100 | round / 100)/mo"
' | sort -t'$' -k4 -rn | head -20

echo ""
echo "=== RDS Rightsizing ==="
cht_api "olap_reports/usage/rds" | jq -r '
    .dimensions[0].items[] |
    select(.recommendation != null) |
    "\(.label)\tCurrent: \(.instance_type)\tRecommended: \(.recommendation.instance_type)\tSavings: $\(.recommendation.savings | . * 100 | round / 100)/mo"
' | sort -t'$' -k4 -rn | head -10

Governance Policy Status

#!/bin/bash
echo "=== Active Policies ==="
cht_api "policies" | jq -r '
    .policies[] | "\(.id)\t\(.name)\t\(.status)\tViolations: \(.violation_count // 0)"
' | column -t | head -20

echo ""
echo "=== Policy Violations ==="
cht_api "policies" | jq -r '
    .policies[] | select(.violation_count > 0) |
    "\(.name)\t\(.violation_count) violations\tSeverity: \(.severity)"
' | sort -t':' -k2 -rn | column -t | head -15

Budget Tracking

#!/bin/bash
echo "=== Budget Summary ==="
cht_api "olap_reports/cost/budget" | jq -r '
    .dimensions[0].items[] |
    "\(.label)\tBudget: $\(.budget | . * 100 | round / 100)\tActual: $\(.actual | . * 100 | round / 100)\tVariance: \(.variance_percent | . * 100 | round / 100)%"
' | column -t | head -15

echo ""
echo "=== Over-Budget Items ==="
cht_api "olap_reports/cost/budget" | jq -r '
    .dimensions[0].items[] |
    select(.variance_percent > 0) |
    "\(.label)\tOver by: $\(.variance | . * 100 | round / 100)\t(\(.variance_percent | . * 100 | round / 100)%)"
' | sort -t'$' -k2 -rn | column -t | head -10

Reserved Instance Analysis

#!/bin/bash
echo "=== RI Utilization ==="
cht_api "olap_reports/cost/ri_utilization" | jq -r '
    .dimensions[0].items[] |
    "\(.label)\tUtilization: \(.utilization_percent | . * 100 | round / 100)%\tCoverage: \(.coverage_percent | . * 100 | round / 100)%"
' | column -t | head -15

echo ""
echo "=== RI Recommendations ==="
cht_api "olap_reports/cost/ri_recommendations" | jq -r '
    .dimensions[0].items[] |
    "\(.label)\t\(.instance_type)\tSavings: $\(.estimated_savings | . * 100 | round / 100)/yr\tBreak-even: \(.break_even_months) months"
' | sort -t'$' -k3 -rn | column -t | head -10

Safety Rules

• Read-only queries: CloudHealth API is primarily for reporting -- policy changes need UI confirmation
• API rate limits: CloudHealth enforces rate limits -- space out bulk queries
• Data freshness: Cost data can lag by 24-48 hours from cloud provider billing
• Multi-account: Always verify account context when reviewing costs

Output Format

Present results as a structured report:

Managing Cloudhealth 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

• Perspective confusion: Different perspectives show different cost aggregations -- verify which perspective is active
• Untagged resources: Resources without tags appear under "unallocated" -- this skews cost attribution
• Blended vs unblended: Blended rates average across RI and on-demand -- use unblended for true cost
• API pagination: Large result sets require pagination -- check for next_page tokens
• Time zones: Cost reports use UTC -- account for timezone differences in daily reports
• Amortized costs: RI upfront payments can be amortized or shown as one-time -- check report settings
