AWS Rightsizing Skill

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

Relationship to other AWS skills:

• aws-rightsizing/ -> "What to resize" (anti-hallucination rules, utilization thresholds, savings estimates)
• aws/ -> "How to execute" (parallel patterns, CloudWatch statistics syntax, throttling)
• aws-pricing/ -> "How much things cost" (on-demand pricing via get_aws_cost)
• aws-billing/ -> "Current spend" (billing context, discount detection)

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.
