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 | $0.00029 | $0.04416 |
| Opus 5 | $0.00015 | $0.02208 |
| Sonnet 5 | $0.00006 | $0.00883 |
| Haiku 4.5 | $0.00003 | $0.00442 |
Grade A, and why
Using Amazon Skills 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 9d 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.

Using Amazon Skills
Overview
This is the meta-skill: it describes how to navigate, select, and combine the other skills in this library. Use this when you're unsure which skill applies, when you need to understand how skills interact, or when you want to establish core operating behaviors that underpin all other skills. Think of this as the operating system on which individual skills run.
When to Use
- Starting a new project and wondering "what's the Amazon way?"
- Unsure which skill applies to your current situation
- Onboarding new team members to this way of working
- Wanting to establish core behaviors before diving into specific practices
- Assessing whether your team is following the overall system, not just individual parts
Amazon Context
Amazon doesn't have a single monolithic process—it has a collection of mechanisms, principles, and practices that compose together. The power comes from the composition: progressive deployment is effective because pipelines enforce safety gates, which work because alarms are set up correctly, which matter because the team operates the service they build. Remove one piece and the others weaken. This meta-skill helps you see the whole system.
Skill Routing Flow Chart
"I'm starting a new project"
Start → Working Backwards (define what customer needs)
→ Dependency Management (if external/system dependencies exist)
→ Feature Flag Lifecycle (if controlled exposure or kill switch is needed)
→ Operational Excellence (operational signals and runbooks)
→ Design Document (technical approach)
→ API Contract First (define interfaces)
→ Infrastructure as Code (define resources)
→ Operational Excellence (set up monitoring)
→ Progressive Deployment (ship safely)
"I'm writing/reviewing code"
Code change → Code Review Bar Raising (quality)
→ Test-Driven Development (coverage)
→ Pipeline Safety (automated gates)
→ Progressive Deployment (ship it)
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.

Using Amazon Skills is a skill published in the GitHub repository robisson/build-like-amazon-agent-skills (14 stars, last pushed 3mo ago), licensed MIT. It adds 29 tokens to every session and 4,416 once invoked, about $0.0001 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 2026-08-30.
