Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.01066 |
| Opus 5 | $0.00018 | $0.00533 |
| Sonnet 5 | $0.00007 | $0.00213 |
| Haiku 4.5 | $0.00004 | $0.00107 |
Grade A, and why
AWS CAF Landing Zones 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.
How it starts
The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
The AWS Cloud Adoption Framework (CAF) is the set of practices for governing AWS at scale. This skill covers the governance essentials you need to design a landing zone that is secure, auditable, and cost-attributable — AWS Organizations OU hierarchy, account design, Service Control Policies (SCPs), IAM scoping, and VPC topology. It deliberately does not reproduce the full landing-zone accelerator (AWS Control Tower / Landing Zone Accelerator); the accelerator is a reference for the complete, opinionated implementation, while this skill is the decision layer you apply to any AWS environment.
When to use it
When designing or reviewing an AWS environment's structure — a new account, an OU reorganization, an SCP/guardrail change, or a network-topology decision. Also before scaffolding a new workload into an existing landing zone, to confirm it fits the established pattern.
AWS Organizations OU hierarchy
- Separate platform (management, connectivity, security) from workload OUs, so governance applied at the platform level inherits down without entangling workload-specific policy.
- Keep the hierarchy shallow and meaningful — a handful of OUs, each with a clear purpose, not a deep tree that mirrors the org chart.
- Apply SCPs and IAM at the highest level where it's uniformly correct, and
let it inherit; override only where a genuine exception exists (and document
it per
iac-expert'sexception-documentationskill).
Account design
- Use accounts as scale units and trust boundaries, not cost centers (cost attribution belongs to tags, not account boundaries).
- Group accounts by environment/workload boundary (e.g. a
prod/nonprodsplit, or one per major workload) so blast radius and policy scope stay manageable. - Keep the management account for billing and organization-wide administration only — never run workloads in it. Use dedicated accounts for shared services (logging, networking) and for each workload/environment.
- Avoid a single account for everything, and avoid one account per microservice — both extremes make governance either impossible or unmanageable.
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 CAF Landing Zones is a skill published in the GitHub repository niels-emmer/myace (1 stars, last pushed 5d ago), licensed MIT. It adds 36 tokens to every session and 1,066 once invoked, about $0.0002 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.
