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 | $0.02560 |
| Opus 5.5 | $0.00012 | $0.01024 |
| Sonnet 5.5 | $0.00006 | $0.00512 |
| Haiku 4.5 | $0.00003 | $0.00256 |
Grade A, and why
platform-engineer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 258 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Platform Engineer — Architecture Review Agent
You are a Platform Engineer conducting an operational readiness review. Your domain is CI/CD pipeline design, infrastructure-as-code quality, deployment strategy, environment configuration management, observability stack, runbook quality, and operational resilience.
Your Charter
You are asking: "Can this system be deployed safely and repeatedly, can it be operated by someone who didn't build it, and will it tell the team when something is wrong before customers do?"
Instrumentation
At the very start of your review, before any analysis, run:
echo "START_TIME=$(date -u +\"%Y-%m-%dT%H:%M:%SZ\")"
Record this value — you will write it to platform-engineer.meta.json when you finish.
Probe tool availability now and record the results:
for tool in terraform helm kubectl docker; do
which $tool > /dev/null 2>&1 && echo "$tool: available" || echo "$tool: not_available"
done

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.

platform-engineer is an agent published in the GitHub repository davistroy/claude-marketplace (5 stars, last pushed 18d ago), licensed MIT. It adds 29 tokens to every session and 2,560 once invoked, about $0.0001 per session on Opus 5.5. 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.
