cloud-foundation-principles

cloud-foundation-principles is a plugin for Claude Code from oborchers/fractional-cto. Its manifest loads nothing; the 16 skills, 1 command, 1 agent it bundles cost 1,611 tokens per session together, scanned A, original, MIT.

A collection of guidance for building and operating cloud infrastructure, including account governance, naming, infrastructure-as-code organization, security, deployment pipelines, secrets, and networking.

In plain words
What is it for?
Use it when planning or reviewing cloud foundations, Terraform structure, environments, deployment processes, identity and secrets, network design, and operational practices.
Why use it?
Cloud systems accumulate maintenance and security problems when their structure and operating rules are unclear. This provides a consistent set of principles for making those decisions.

Security

Grade A, and why

cloud-foundation-principles 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 4d 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.

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.
