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 | $0.00033 | $0.01899 |
| Opus 5 | $0.00016 | $0.00949 |
| Sonnet 5 | $0.00007 | $0.00380 |
| Haiku 4.5 | $0.00003 | $0.00190 |
Grade A, and why
Operational Excellence 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 10d 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 — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Operational Excellence
Overview
Operational excellence means your service is observable, alarmed, and documented such that any on-call engineer can understand its health and respond to problems—even at 3 AM without the original author available. This requires dashboards that show the right metrics at the right granularity, alarms that fire at the right thresholds with the right severity, and runbooks that provide actionable steps for each alarm.
When to Use
- Building a new service (operational readiness before launch)
- Reviewing an existing service's operational posture
- After any incident where detection or response was slower than expected
- When onboarding a new team member to on-call
- During operational readiness reviews (ORR)
- When service metrics indicate degradation trends
Agent Persona
Load agents/ops-bar-raiser.md when evaluating dashboards, alarms, runbooks, and operational burden. Use it to challenge whether the service can be diagnosed, mitigated, and rolled back by someone who did not write the code.
Amazon Context
At Amazon, you build it, you own it, you operate it. There is no separate operations team that runs your service. The team that writes the code carries the pager. This means operational excellence is not an afterthought—it's a core competency of every engineer. A service without proper alarms is a service where customers discover problems before you do. A service without runbooks is a service where every incident requires the original author, creating a single point of failure.
The Process
Dashboards
Every service needs three dashboard levels:
Level 1: Customer Experience Dashboard (primary)
- Availability: successful requests / total requests (target: 99.9%+ or per-SLA)
- Latency: p50, p90, p99, p99.9 (separate graphs, not averaged)
- Error rate: 5xx rate, client error rate (4xx), timeout rate
- Throughput: requests per second (to detect traffic anomalies)
- Business metrics: orders/sec, messages delivered/sec, etc.
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.

Operational Excellence is a skill published in the GitHub repository robisson/build-like-amazon-agent-skills (15 stars, last pushed 3mo ago), licensed MIT. It adds 33 tokens to every session and 1,899 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 2026-08-30.
