ecs-soci

ecs-soci is a skill for Claude Code from aws-samples/sample-claude-code-plugins-for-startups. It costs 98 tokens per session (4,078 once invoked), scanned A, original, MIT-0.

A Terraform example for running an Amazon ECS service on AWS Fargate with SOCI, a format that lets container images load parts as needed instead of all at once. It compares startup with and without SOCI using a PyTorch and FastAPI machine-learning container.

In plain words
What is it for?
Use it to study or test SOCI index v2 manifests, configure an ECS Fargate task with Terraform, and compare startup behavior for a large inference container.
Why use it?
Large container images can make new tasks take longer to start. This example shows how lazy loading may reduce that startup work.

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

ecs-soci 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 2mo 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.

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.
