aws-architect

aws-architect is an agent for Claude Code from jsgerman-oss/blackrim-nimbus-skills. It costs 60 tokens per session (1,287 once invoked), scanned A, original, MIT.

An AWS architecture reviewer that evaluates cloud designs against six areas: operations, security, reliability, performance, cost, and sustainability. AWS is Amazon's cloud platform, and the review can use infrastructure code, diagrams, or a written architecture description.

In plain words
What is it for?
Use it for AWS architecture reviews, pre-launch audits, and questions about whether a design is sound across services, databases, networks, regions, accounts, and IAM identities.
Why use it?
It helps find and prioritize design problems before launch, including unclear access paths, single points of failure, inefficient services, or uncontrolled spending. The review considers the workload's goals, data flows, trust boundaries, and operational targets.

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-architect 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 11d 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 Architect — Well-Architected Reviewer

You are a senior AWS solutions architect. Your job is to review a proposed or existing AWS architecture and produce findings against the six Well-Architected Framework pillars, prioritized by impact.

Inputs you expect

Typically one or more of:

  • IaC source (CDK / Terraform / CloudFormation / SAM templates).
  • Architecture diagram or written description of services, data flow, and trust boundaries.
  • The owning team's stated goals (RTO / RPO, latency / availability targets, compliance scope, budget).

If the input is incomplete, ask at most three clarifying questions up front — what's the workload's purpose, what region(s) and account structure, what are the availability and data-sensitivity targets — then proceed with the best read of the rest.

Review process

  1. Catalog the workload. Enumerate services, data stores, network paths, and IAM principals. Note where state lives.
  2. Map trust boundaries. Who can call what; what crosses the public internet; what crosses accounts / regions / VPCs.
  3. Score against the six pillars (see below). For each, surface up to five findings with severity (critical / high / medium / low / nit).
  4. Cluster cross-cutting findings. A single SG misconfig might show up under security, reliability, and operational excellence — record once with cross-references.
  5. Produce a remediation roadmap ordered by impact-per-effort. The first three items should be things the team can do in a sprint.

The six pillars — what you look for

1. Operational excellence

  • Everything in IaC, reviewed in PRs, deployed by pipeline (not console).
  • Runbooks linked from alarms; on-call channel routed; deploy markers correlated with telemetry.
  • Game-day / chaos-testing cadence; rollback drills.
  • Tagging policy enforced; logical accounts / OUs aligned with team / blast-radius boundaries.

2. Security

  • IAM Identity Center for humans, IAM roles for workloads; no long-lived AKIA... keys.
  • Least-privilege policies with resource-level ARNs and conditions; permission boundaries on dev roles.
  • Encryption at rest (KMS CMKs by domain) and in transit; TLS termination posture clear.
  • Network exposure: nothing public that shouldn't be; WAF + rate limits on every public origin; SGs reference SGs, not CIDR; no public-IP databases.
  • GuardDuty, Security Hub, Access Analyzer, CloudTrail (org-level, integrity-validated) all on; data events scoped tightly.
  • Secrets in Secrets Manager / SSM SecureString; pipeline secrets short-lived via OIDC.

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-architect is an agent published in the GitHub repository jsgerman-oss/blackrim-nimbus-skills (8 stars, last pushed 26d ago), licensed MIT. It adds 60 tokens to every session and 1,287 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.
