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-well-architected-review 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.

Provider hierarchy: official MCP (awslabs/mcp family, mcp-proxy-for-aws GA) > custom prompts for account-aware ops (live context, auth via AWS_PROFILE/AWS_REGION); prompts (this skill checklist) remain fallback for offline/low-privilege/CI. See docs/cloud/research-384-candidates.md.

When to use

  • Designing or reviewing workload on AWS against 6 pillars.
  • Running Well-Architected Review (WAR) without console Tool access.

Instructions

  1. Run checklist per pillar: operational excellence (runbooks, observability), security (IAM, encryption, least privilege), reliability (multi-AZ, backup, retry), performance (right-sizing, caching), cost (graviton, S3 lifecycle), sustainability (right-sizing, serverless).
  2. Map to cloud-design-patterns where relevant (e.g., reliability → Circuit Breaker).
  3. If live account: delegate to awslabs/mcp (mcp-proxy-for-aws or awslabs.core-mcp-server uvx) for context; else do NOT paste ${AWS_*} secrets — use placeholders ${AWS_PROFILE}, ${AWS_REGION}, ${AWS_ACCOUNT_ID}.
  4. Record findings as High/Medium/Low risk per pillar and link to lenses/hands-on labs.

Security

  • Must not exfiltrate credentials; use ${AWS_*} placeholders; mark aws-well-architected-review as optional (no vendor lock).

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.
