Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.01191 |
| Opus 5 | $0.00030 | $0.00596 |
| Sonnet 5 | $0.00012 | $0.00238 |
| Haiku 4.5 | $0.00006 | $0.00119 |
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::CacheClusterandAWS::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:
ReplicationGroupfor production Redis-style deployments that need failover, replicas, or shardingCacheClusterfor 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 ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

aws-cloudformation-elasticache is a skill published in the GitHub repository giuseppe-trisciuoglio/developer-kit (343 stars, last pushed 21d ago), licensed MIT. It adds 61 tokens to every session and 1,191 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
