AWS FinOps — Cost Optimization & Reservations

This skill covers AWS cost optimization: identifying waste, right-sizing workloads, choosing the right storage classes and instance families, planning commitment purchases (Savings Plans, RIs, reserved nodes for RDS/ElastiCache/OpenSearch/Redshift/DynamoDB), and using AWS-native cost tooling (Cost Explorer, CUR, Compute Optimizer, Trusted Advisor, Budgets).

Scripts: Always run scripts with --help first. Scripts call the AWS CLI and assume credentials are already configured (env vars, profile, or instance role). Do not read script source unless debugging the script itself.

References: Load reference files on demand. Do not pre-load all references.

Slash commands: Users can also invoke these directly:

• /finops-skills:finops-audit [account-or-profile] — Account-wide waste audit (idle resources, untagged spend, gp2 volumes, old snapshots)
• /finops-skills:finops-rightsize [resource-id] — Analyze a workload (EC2 / RDS / ASG) and recommend instance/RDS sizing
• /finops-skills:finops-commit — Recommend a coordinated reservation portfolio (Savings Plans + RDS/ElastiCache/OpenSearch RIs)
