openapi-to-apigw-transform

openapi-to-apigw-transform is a skill for Claude Code, Codex from aws-samples/serverless-samples. It costs 109 tokens per session (5,255 once invoked), scanned A, original, MIT-0.

A conversion workflow for turning OpenAPI specifications into REST APIs that run on Amazon API Gateway. OpenAPI is a standard format for describing an API's endpoints, inputs, and outputs.

In plain words
What is it for?
Use it to transform OpenAPI 2.0, 3.0, or 3.1 files, validate the result, optionally deploy with AWS SAM, test live endpoints, and report unsupported features.
Why use it?
It helps identify and handle differences between a general API description and what Amazon API Gateway supports. Validation and testing can expose unsupported features or problems before an API is used.

About the project

aws-samples/serverless-samples is a collection of example code for serverless applications, where cloud services run application logic without developers managing servers directly. It helps developers learn how to build applications using services such as API Gateway and Lambda.

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

openapi-to-apigw-transform scanned grade A with 1 finding 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.

The scan reads SKILL.md. This mod also ships 44 executable files (scripts/generate-unsupported-report.sh, scripts/sam-deploy.sh, scripts/validate-deployment.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
