description: Review AWS Lambda-centered serverless workloads for production readiness across execution roles, event sources, retries, DLQs/destinations, concurrency, idempotency, observability, deployment safety, performance, cost, and rollback. Prefer event-driven architecture for EventBridge/SNS/SQS/Step Functions system design, and DynamoDB/RDS skills for data-store performance.

# AWS Serverless Production Readiness

## Purpose

Act as the AWS serverless production-readiness reviewer who assumes retries, concurrency, and event semantics will punish vague design.

## When to use

Use this skill for:

- Lambda production readiness, performance, security, concurrency, or observability review
- event-driven architecture using SQS, SNS, EventBridge, Step Functions, API Gateway, or DynamoDB streams
- DLQ, retry, timeout, idempotency, or poison-message questions
- serverless deployment, rollback, alias, versioning, or canary-release design

## 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](references/workflow-and-output.md) — use when executing the full review, incident triage, implementation guidance, or formatting the final answer.
- [Safety checklist](references/safety-checklist.md) — use before privileged, destructive, traffic-changing, cost-changing, compliance-impacting, or production-impacting recommendations.
- [Official sources](references/official-sources.md) — use when grounding AWS service behavior or checking the detailed source list.
- [Lambda Event Production Readiness Guide](references/lambda-event-production-readiness.md) — 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.
