architecture

architecture is a skill for Claude Code from cass-2003/local-workflow-skill. It costs 41 tokens per session (351 once invoked), scanned A, a copy of architecture, MIT.

An architecture design guide for APIs, security, cloud-native systems, data protection, messaging, and caching. It also covers common design principles such as SOLID and zero-trust security.

In plain words
What is it for?
Use it to plan APIs, choose cloud-native components, design security controls, work with message queues, and decide how caching should behave.
Why use it?
It gives developers a structured way to think about how system parts fit together, including reliability, security, and scaling concerns.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

architecture 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 5d 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.

Origin

This is a copy

100% identical to architecture — 84 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with 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.
