architecture-designer

A guided workflow for designing software architecture and infrastructure, from gathering requirements through implementation. It includes Mermaid diagrams, browser previews, and structured documentation; Mermaid is a text format for creating diagrams.

In plain words
What is it for?
Use it to plan databases, services, infrastructure, and implementations, and to create or review C4 architecture diagrams using Mermaid.
Why use it?
It helps turn broad technical requirements into documented system designs that can be reviewed before implementation. It also supports examining architecture drift and planning remediation, meaning fixes for differences between the intended and actual system.

Grade A, and why

architecture-designer 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 2d 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.
