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 | $0.00101 | $0.02984 |
| Opus 5 | $0.00051 | $0.01492 |
| Sonnet 5 | $0.00020 | $0.00597 |
| Haiku 4.5 | $0.00010 | $0.00298 |
Grade A, and why
aws-cloudformation-ecs 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 ECS
Overview
Provides CloudFormation patterns for ECS clusters, task definitions, services, container definitions, auto scaling, blue/green deployments, ALB integration, monitoring, and cross-stack references.
When to Use
- Creating or updating ECS clusters with CloudFormation
- Configuring Fargate/EC2 launch types and capacity providers
- Deploying services with ALB/NLB integration or blue/green deployments
- Implementing auto scaling for ECS services
- Setting up monitoring with Container Insights
Instructions
Follow these steps to create ECS infrastructure with CloudFormation:
1. Define ECS Cluster Parameters
Specify launch type, networking, and capacity settings:
Parameters:
LaunchType:
Type: String
Default: FARGATE
AllowedValues:
- EC2
- FARGATE
Description: ECS launch type
ContainerPort:
Type: Number
Default: 80
Description: Container port
TaskCPU:
Type: String
Default: 256
AllowedValues:
- 256
- 512
- 1024
- 2048
- 4096
Description: Task CPU units
TaskMemory:
Type: String
Default: 512
AllowedValues:
- 512
- 1024
- 2048
- 3072
- 4096
- 5120
- 6144
- 7168
- 8192
- 9216
- 10240
Description: Task memory in MB
2. Create ECS Cluster
Define the cluster infrastructure:
Resources:
ECSCluster:
Type: AWS::ECS::Cluster
Properties:
ClusterName: !Sub "${AWS::StackName}-cluster"
ClusterSettings:
- Name: containerInsights
Value: enabled
CapacityProviders:
- FARGATE
- FARGATE_SPOT
DefaultCapacityProviderStrategy:
- CapacityProvider: FARGATE
Weight: 1
- CapacityProvider: FARGATE_SPOT
Weight: 0
3. Create Task Definition
Define container configurations:
Resources:
TaskDefinition:
Type: AWS::ECS::TaskDefinition
Properties:
Family: !Sub "${AWS::StackName}-task"
NetworkMode: awsvpc
RequiresCompatibilities:
- FARGATE
Cpu: !Ref TaskCPU
Memory: !Ref TaskMemory
ExecutionRoleArn: !Ref ExecutionRole
TaskRoleArn: !Ref TaskRole
ContainerDefinitions:
- Name: application
Image: !Ref ImageUrl
PortMappings:
- ContainerPort: !Ref ContainerPort
Protocol: tcp
Environment:
- Name: LOG_LEVEL
Value: INFO
LogConfiguration:
LogDriver: awslogs
Options:
awslogs-group: !Ref LogGroup
awslogs-region: !Ref AWS::Region
awslogs-stream-prefix: ecs
Memory: !Ref TaskMemory
What ships with it
3 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-ecs is a skill published in the GitHub repository giuseppe-trisciuoglio/developer-kit (343 stars, last pushed 21d ago), licensed MIT. It adds 101 tokens to every session and 2,984 once invoked, about $0.0005 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.
