aws-compute

aws-compute is a skill for Claude Code from jsgerman-oss/blackrim-nimbus-skills. It costs 58 tokens per session (1,783 once invoked), scanned A, original, MIT.

AWS compute guidance helps choose and configure the AWS service that runs your code, such as Lambda, containers, virtual machines, or batch jobs.

In plain words
What is it for?
Use it to choose a runtime, size Lambda, ECS, or EC2 resources, configure autoscaling, compare ECS with Kubernetes, reduce startup delays, and review compute permissions.
Why use it?
It removes guesswork when balancing cost, speed, capacity, scaling, and availability. It also helps identify configuration and access-control risks.

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

aws-compute 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 12d 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 Compute

When to use

  • Designing a new workload and choosing between serverless and container / VM compute.
  • Tuning Lambda memory / timeout / concurrency, or chasing cold-start latency.
  • Right-sizing ECS task definitions or EC2 instance families.
  • Deciding ECS vs EKS for a containerized workload.
  • Reviewing autoscaling, capacity, and warm-pool configuration.
  • Auditing IAM execution roles attached to compute.

Decision tree

  1. Event-driven, < 15 min, irregular load, no persistent connections → Lambda.
  2. Long-running HTTP service, container-friendly, no Kubernetes investment → App Runner or ECS / Fargate behind ALB.
  3. Container fleet with sidecars, service mesh, GitOps, multi-tenant → EKS.
  4. GPU, FPGA, custom kernel, license-restricted AMI, > 14-day workloads → EC2.
  5. Throughput-oriented batch (rendering, genomics, ETL) → AWS Batch on Fargate or EC2 Spot.

Defaults

Lambda

  • Architecture: arm64 (Graviton) unless a native dep is x86-only — ~20% cheaper, often faster.
  • Memory: start at 1024 MB, profile with Lambda Power Tuning, then trim.
  • Timeout: set to 99p observed duration × 1.5; never the API-Gateway-mandated 29 s unless intentional.
  • Concurrency: set reserved concurrency on every prod function to cap blast radius from a runaway upstream.
  • VPC: only attach to a VPC if you actually need private resources — ENI cold-starts hurt.
  • Packaging: container image if dependencies > 50 MB; otherwise zip with Lambda layers for shared deps.
  • Idempotency: design every handler to be safely retried. SQS triggers will replay; EventBridge will redeliver.

ECS / Fargate

  • Platform version: LATEST, but pin in IaC so a new release doesn't surprise you mid-incident.
  • Task CPU / memory: pick from the supported pairs; over-provisioning memory is cheaper than CPU-bound throttling.
  • Service discovery: AWS Cloud Map or service connect — avoid hand-rolled DNS.
  • Deployment: CODE_DEPLOY blue/green for any user-facing service; ECS rolling for back-of-house.
  • Health check grace period: at least 60 s for JVM / .NET, 30 s for Go / Node / Python.

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-compute is a skill published in the GitHub repository jsgerman-oss/blackrim-nimbus-skills (8 stars, last pushed 27d ago), licensed MIT. It adds 58 tokens to every session and 1,783 once invoked, about $0.0003 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 2026-08-31.
