architecture

architecture is a skill for Claude Code, Codex from atstaeff/ai-agents. It costs 22 tokens per session (221 once invoked), scanned A, original, MIT.

A software-architecture guide covering ways to structure applications and services. Its topics include APIs, cloud systems, microservices, domain-driven design, security, and performance.

In plain words
What is it for?
Use it when designing or reviewing APIs, cloud-native systems, microservices, domain models, performance improvements, or security architecture.
Why use it?
It helps developers choose a suitable system structure and address scaling, security, and maintainability concerns early.

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.

What it actually says

Architecture Skill

Instructions for AI

Apply software architecture patterns and best practices when designing, reviewing, or evolving systems. Use these sub-skills for domain-specific architectural guidance.

Sub-Skills

  • API Design — Design robust, scalable, and developer-friendly APIs
  • Cloud Native — Cloud-native architecture patterns and practices
  • Domain-Driven Design — DDD strategic and tactical patterns
  • Microservices — Microservice architecture patterns and decomposition
  • Performance — Performance optimization and scalability patterns
  • Security — Security architecture and secure-by-design practices
Files

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

architecture is a skill published in the GitHub repository atstaeff/ai-agents (2 stars, last pushed 6mo ago), licensed MIT. It adds 22 tokens to every session and 221 once invoked, about $0.0001 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 2026-08-31.
