Reviewer Notes

SST is primarily a local development framework and CLI tool rather than an API-first service, making it poorly suited for agent discovery and autonomous interaction. The tool lacks MCP server, OpenAPI spec, and llms.txt documentation—agents would need to rely on CLI parsing or programmatic spawning of processes. AWS credential setup is required upfront, and there's no programmatic account creation pathway; agents would need pre-configured AWS access. While the TypeScript SDK and infrastructure code patterns are well-documented, the framework's design assumes human developers running it locally rather than autonomous agents orchestrating deployments remotely.
