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 | $0.00070 | $0.02761 |
| Opus 5.5 | $0.00028 | $0.01104 |
| Sonnet 5.5 | $0.00014 | $0.00552 |
| Haiku 4.5 | $0.00007 | $0.00276 |
Grade A, and why
aws-cloudformation-lambda 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 1mo 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 Lambda Functions
Overview
Create production-ready Lambda functions using CloudFormation templates with validation and deployment workflows.
When to Use
- Creating Lambda functions with CloudFormation
- Configuring event sources (S3, SQS, DynamoDB, Kinesis)
- Implementing Lambda layers and cold start optimization
- Integrating Lambda with API Gateway
- Deploying Lambda infrastructure with validation
Deployment Workflow
Always follow this deployment workflow:
1. Validate Template
aws cloudformation validate-template --template-body file://template.yaml
2. Deploy Stack
aws cloudformation deploy \
--template-file template.yaml \
--stack-name my-lambda-stack \
--capabilities CAPABILITY_IAM \
--parameter-overrides Environment=prod
3. Monitor Stack Events
aws cloudformation describe-stack-events \
--stack-name my-lambda-stack \
--query 'StackEvents[?ResourceStatus==`CREATE_FAILED`||ResourceStatus==`UPDATE_FAILED`]'
4. Verify Resources
aws lambda get-function --function-name my-lambda-stack-function
aws cloudformation describe-stacks --stack-name my-lambda-stack \
--query 'Stacks[0].StackStatus'
5. Rollback on Failure
aws cloudformation delete-stack --stack-name my-lambda-stack
aws logs describe-log-groups --log-group-name-prefix "/aws/lambda/my-lambda"

Description: Lambda function memory in MB
FunctionTimeout:
Type: Number
Default: 30
MinValue: 1
MaxValue: 900
Description: Function timeout in seconds
Runtime:
Type: String
Default: nodejs20.x
AllowedValues:
- nodejs20.x

- dotnet8
- go1.x
Description: Lambda runtime environment
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-lambda is a skill published in the GitHub repository giuseppe-trisciuoglio/developer-kit (359 stars, last pushed 1mo ago), licensed MIT. It adds 70 tokens to every session and 2,761 once invoked, about $0.0003 per session on Opus 5.5. 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.
