GCP Rightsizing Skill

Analyze resource utilization and identify right-sizing opportunities with anti-hallucination guardrails and reusable Cloud Monitoring functions.

Relationship to other GCP skills:

• gcp-rightsizing/ -> "What is oversized" (utilization thresholds, downsize recommendations)
• gcp-idle-resources/ -> "What is wasting money" (idle detection rules, cost estimation)
• gcp/ -> "How to execute" (parallel patterns, monitoring aligners, billing/pricing scripts)

CRITICAL: Rightsizing Rules (Anti-Hallucination)

These rules are MANDATORY when analyzing resource utilization. Violating them produces incorrect recommendations that can cause outages.

Rule 1: Minimum 14-Day Observation Window

Short observation windows miss weekly patterns (batch jobs, weekend traffic, month-end spikes). Default --days 14, allow up to 90.
