aws-cloudformation-elasticache

aws-cloudformation-elasticache is a skill for Claude Code from giuseppe-trisciuoglio/developer-kit. It costs 61 tokens per session (1,191 once invoked), scanned A, original, MIT.

A set of AWS CloudFormation patterns for defining ElastiCache Redis or Memcached services as code. CloudFormation is AWS’s system for creating and managing infrastructure from templates.

In plain words
What is it for?
Use it to design cache clusters or replicated Redis, configure subnet and parameter groups, set security and availability options, and share cache endpoints with other stacks.
Why use it?
It helps avoid unsafe or incomplete cache configurations, including poor network placement, missing encryption, and risky changes that can cause replacement or downtime.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

aws-cloudformation-elasticache scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AWS CloudFormation ElastiCache

Overview

Use this skill to model ElastiCache infrastructure with CloudFormation without turning SKILL.md into a full service manual.

Focus on the delivery decisions that matter most:

  • choosing the right cache topology
  • placing the cache safely inside a VPC
  • configuring availability, encryption, and exports for downstream stacks

Use the bundled references/ documents for larger production templates and service-specific detail.

When to Use

Use this skill when:

  • creating a Redis or Memcached cache tier with CloudFormation
  • deciding between AWS::ElastiCache::CacheCluster and AWS::ElastiCache::ReplicationGroup
  • configuring subnet groups, parameter groups, and security groups for application access
  • adding snapshots, maintenance windows, encryption, and Multi-AZ behavior
  • exporting cache endpoints to application or platform stacks
  • reviewing cache changes for replacement risk, downtime, or operational cost

Typical trigger phrases include cloudformation elasticache, redis replication group, memcached cluster, cache subnet group, and export redis endpoint.

Instructions

1. Choose the cache topology first

Use:

  • ReplicationGroup for production Redis-style deployments that need failover, replicas, or sharding
  • CacheCluster for Memcached or simple single-node cache scenarios

Do not start with resource YAML before deciding whether the application needs durability, read replicas, cluster mode, or just an ephemeral cache.

2. Model the network boundary explicitly

Create and wire:

  • a subnet group with private application subnets
  • a security group that allows access only from the application tier
  • parameter groups only when default engine settings are insufficient

Keep the cache private unless there is a very unusual and well-reviewed reason not to.

3. Configure durability and security based on environment

For production-style Redis deployments, decide on:

  • automatic failover and Multi-AZ
  • at-rest and in-transit encryption
  • snapshot retention and maintenance windows
  • authentication or auth token strategy where supported

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
