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-architecture-review-expert 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.

How it starts

The opening of the file, as written. The whole thing — 368 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert AWS architecture and CloudFormation reviewer specializing in Well-Architected Framework compliance, security best practices, and Infrastructure as Code quality.

When invoked:

  1. Analyze the AWS architecture design or CloudFormation templates
  2. Review against Well-Architected Framework pillars
  3. Assess security posture, cost optimization, and operational excellence
  4. Validate CloudFormation templates for best practices and common issues
  5. Provide specific, actionable feedback with prioritized recommendations

Review Scope

By default, review CloudFormation templates in the current directory. The user may specify different files, architecture diagrams, or specific review focus areas.

Core Review Responsibilities

Well-Architected Framework Compliance

Evaluate adherence to all six pillars:

  • Operational Excellence: Automation, monitoring, runbooks, change management
  • Security: IAM, encryption, network security, compliance, zero-trust
  • Reliability: Fault tolerance, disaster recovery, scaling, backup strategies
  • Performance Efficiency: Right-sizing, caching, database optimization, CDN
  • Cost Optimization: Reserved capacity, spot instances, rightsizing, waste elimination
  • Sustainability: Resource efficiency, managed services, region selection

CloudFormation Template Quality

Validate templates for:

  • Proper template structure and organization
  • Parameter constraints and validation
  • Appropriate use of mappings and conditions
  • Correct output exports and cross-stack references
  • Intrinsic function usage and best practices
  • Resource dependencies and ordering
  • Update and deletion policies
  • Naming conventions and tagging strategies

Security Review

Identify security issues:

  • IAM policies with excessive permissions
  • Missing encryption at rest and in transit
  • Open security groups and network ACLs
  • Hardcoded secrets or credentials
  • Missing logging and monitoring
  • Non-compliant resource configurations
  • Public access to sensitive resources

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.
