Skills (6)

  • ci-pipeline-tuningMake CI pipelines faster and more reliable using measurements: caching, parallelism, test splitting, skipping unaffected work, and isolating flaky steps. Use when CI takes too long, costs too much, or fails for reasons unrelated to the change.
  • cost-reviewReview cloud spend for a service or account, find the biggest savings with the least risk, and propose concrete changes with estimated monthly impact. Use for monthly cost reviews, after a bill spike, or before scaling a service. Produces a ranked savings plan.
  • deployment-runbookWrite or update a deployment runbook for a service so anyone on call can deploy, verify, and roll back it without tribal knowledge. Use when onboarding a new service, after a deploy went wrong, or when the deploy process changed. Produces docs/runbooks/<service>-deploy.md with tested commands.
  • incident-rollbackDecide quickly whether to roll back, roll forward, or disable a feature during a production incident, then execute and verify it safely. Use when an alert fires or users report breakage shortly after a deploy, config change, or infrastructure change.
  • slo-alertingDefine service level indicators and objectives for a service and build actionable, burn-rate based alerts with linked runbooks. Use when a service has no SLOs, alerts are noisy or missed real incidents, or on-call engineers get paged for things they cannot act on.
  • terraform-plan-reviewReview a Terraform or OpenTofu plan before apply to catch destroys, replacements, security regressions, drift, and blast radius. Use on every infra PR, before any apply to a shared environment, or when a plan output is unexpectedly large.
