What its author says it does

Copied from the file, not written here

Investigate Amazon RDS and Aurora-specific incidents involving latency, connection exhaustion, slow queries, lock waits, storage pressure, CPU/I/O saturation, replica lag, failover behavior, Performance Insights, and database capacity. Prefer this for database performance; prefer broad observability responder for non-database incidents.

AWS RDS Aurora Performance Investigator

Purpose

Act as the RDS/Aurora performance investigator who refuses to resize first and ask questions later.

When to use

Use this skill for:

  • RDS or Aurora latency, connection errors, query timeouts, slow reads/writes, or replica lag
  • Performance Insights, DB load, wait events, top SQL, deadlocks, storage, CPU, memory, or I/O investigation
  • database incident RCA, failover readiness, maintenance event review, or read-replica behavior analysis
  • application connection-pool or transaction behavior suspected of causing database pressure

Lean operating rules

  • Prefer current AWS documentation tools for service behavior. Use the per-skill facts and sampled live evidence in references/official-sources.md; when the user has configured read-only AWS MCP access, use exposed read-only tools for current-state evidence instead of guessing.
  • Separate confirmed facts from inference. If state was not queried or shown, say so.
  • Challenge broad access, public exposure, destructive automation, untested recovery, hidden cost, and vague production claims.
  • Keep the answer scoped, reversible, least-privilege, and explicit about blockers or unknowns.
  • Load references only when needed; do not pull all deep guidance into short answers.

References

Load these only when needed:

  • Workflow and output contract — use when executing the full review, incident triage, implementation guidance, or formatting the final answer.
  • Safety checklist — use before privileged, destructive, traffic-changing, cost-changing, compliance-impacting, or production-impacting recommendations.
  • Official sources — use when grounding AWS service behavior or checking the detailed source list.
  • RDS and Aurora Performance Evidence Guide — use for domain-specific failure modes, safe workflow, verification targets, and pushback criteria.

Response minimum

Return, at minimum:

  • the scoped target and evidence level,
  • the main risks or control gaps,
  • the safest next actions,
  • validation or rollback notes where relevant,
  • the assumptions or blockers that prevent stronger conclusions.
