Claude Skills by VincentChuWaiChow

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.

Review AWS resilience and business continuity strategy across RTO/RPO, dependency maps, multi-AZ, multi-Region, failover/failback, game days, runbooks, drift, and recovery validation. Prefer data protection backup steward for backup-plan/vault/restore implementation details.

Review Amazon S3 data perimeter and exposure posture across Block Public Access, Object Ownership, ACL removal, bucket/access point policies, TLS-only access, encryption, replication, lifecycle, logging, cross-account access, and prefix boundaries. Prefer this for S3 data exposure; prefer IAM skill for generic policy surgery.

Review broad AWS security posture across Security Hub CSPM, GuardDuty, Inspector, Macie, Config, CloudTrail, IAM, public exposure, vulnerability findings, and remediation governance. Prefer compliance evidence mapper for audit evidence packs, IAM skill for policy surgery, S3 perimeter for S3 exposure, Bedrock governor for GenAI agents, and KMS/secrets steward for crypto/secret lifecycle.

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.

Patch AWS serverless rollout definitions across Lambda, API Gateway, EventBridge, SQS, SNS, event source wiring, aliases, versions, and deployment config. Prefer this for repo-side rollout corrections; do not perform live rollout actions or destructive operations.

Design and stress-test AWS cross-domain solution architectures when the request spans multiple AWS domains or needs an architecture decision record. Prefer narrower AWS skills for single-domain IAM, network, EKS, ECS, serverless, RDS, DynamoDB, S3, Bedrock, IaC, cost, security, migration, compliance, or incident asks.

Triage AWS tickets and alerts using priority, owner, evidence, incident context, escalation path, OpsCenter, health signals, and safe next steps. Prefer this for non-destructive request coordination and escalation; prefer deep domain skills for implementation or root-cause investigation.

Review AWS workload cost posture against the Well-Architected Framework Cost Optimization Pillar.

Audit Azure Key Vault secret lifecycle posture across RBAC, soft delete, purge protection, rotation, expiration, metadata hygiene, Event Grid notifications, and recovery readiness. Use when the question is whether secret management is actually safe, not just present.

Use this skill when reviewing Azure Key Vault certificate issuer configurations for cert-manager on AKS. Trigger on any request to audit Key Vault certificate policies, Managed Identity role assignments, exportability settings, private endpoint connectivity, integrated CA credentials, or rotation policy alignment.

Use this skill for Azure landing-zone design, management-group and subscription hierarchy reviews, platform-versus-application boundary decisions, or multi-subscription Azure platform architecture critiques that span governance, identity, networking, security, and operations.

Guard live AKS deployment rollouts with PDB audit, maxUnavailable/surge validation, rollout pause/undo gates, and post-rollout health verification.

Guard live App Service slot swaps with sticky-settings audit, warmup probe verification, swap-with-preview staging, and instant rollback posture.

Use this skill to classify a user task, select the right Azure specialist agent or team of specialists from the catalog, and dispatch them. Single specialist for focused single-domain tasks; parallel team (max 4) for tasks that span multiple domains. Never auto-dispatches live-guard agents — those always pause for human confirmation.

Plan and stress-test Azure migration cutovers across landing-zone readiness, Azure Migrate assessments, dependency sequencing, permissions, rollback, and operational ownership. Use when a migration plan needs a go/no-go verdict instead of vague optimism.

Use this skill for Azure network architecture review, hub-spoke critique, routing and DNS dependency analysis, shared-services boundary decisions, firewall placement review, and landing-zone connectivity guidance.

Use this skill for Azure Monitor, Log Analytics, Application Insights, alerting, KQL triage, telemetry-gap analysis, workbooks, or operator-grade incident and posture investigations.

Use this skill when the user asks which Azure role to assign, how to grant minimum access, whether a built-in role is sufficient, or when a custom role may be required.

Use this skill for Azure security posture review, baseline hardening, managed identity adoption, Key Vault posture, private access decisions, Azure Policy guardrails, and logging or audit gap analysis. Trigger when the user asks how to harden an Azure workload or platform without defaulting to broad access or public exposure.

Use this skill for Azure management-group hierarchy, subscription placement, resource-group boundary, and platform-versus-workload ownership decisions that affect governance, operations, and landing-zone scale.

Review Azure workload cost posture against the Well-Architected Framework Cost Optimization pillar: cost modeling, rightsizing, reservations, hybrid benefit, storage lifecycle, and idle resource elimination.

Use this skill when reviewing Backstage Scaffolder software templates. Trigger when the user asks whether a template is safe for developer self-service, whether template RBAC gates are in place, whether input parameters are validated, whether a step action has excessive blast radius, or whether template outputs expose secrets.

Use this skill when reviewing cert-manager PKI configuration for Kubernetes clusters. Trigger when the user asks about Issuer or ClusterIssuer scope, CertificateRequestPolicy coverage, certificate SAN or duration risks, trust-manager bundle distribution, SPIFFE mesh CA integration, cert-manager webhook health, or cloud CA authentication method.
