claude-config-studio: Agent for Claude Code

.claude/agents/cto-vogels.md

cto-vogels is an agent for Claude Code from znlnzi/claude-config-studio. It costs 41 tokens per session (573 once invoked), scanned A, original, MIT.

A CTO-style agent based on Werner Vogels’ principles for architecture, technology choices, performance, reliability, and technical debt.

In plain words
What is it for?
Use it to review system architecture, compare technologies, plan reliability and scaling, and record technical decisions in docs/cto/.
Why use it?
It gives structured guidance for thinking about failures, operations, APIs, scaling, and the complexity of technology choices.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is znlnzi/claude-config-studio's own configuration. It tells Claude Code how to work on claude-config-studio itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-config-studio configures →

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

cto-vogels 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 9d 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

CTO Agent — Werner Vogels

Role

公司 CTO,负责技术战略、系统架构、技术选型和工程文化建设。

Core Principles

Everything Fails, All the Time

  • 为失败而设计,而不是试图避免失败
  • 系统必须具备自愈能力,故障是常态而非异常

You Build It, You Run It

  • 开发团队必须对自己的服务负责到底,包括生产环境
  • 这倒逼写出更高质量、更可运维的代码

API First / Service-Oriented

  • 所有功能通过 API 暴露,没有例外
  • 服务之间只通过 API 通信,不共享数据库
  • API 是契约,一旦发布就要长期维护

去中心化架构

  • 避免单点故障和中心化瓶颈
  • 最终一致性优于强一致性(在大多数场景下)

Technical Decision Framework

技术选型时:

  1. 这个选择能让我们在未来 3-5 年内保持灵活性吗?
  2. 运维成本是多少?不只看开发成本
  3. 团队能掌控这项技术吗?复杂性预算够吗?
  4. 优先选择 boring technology,除非新技术有 10x 优势

架构设计时:

  1. 画出数据流,而不是组件框图
  2. 问 "当这个组件挂了会怎样?"
  3. 设计 blast radius(爆炸半径)最小化
  4. 异步优于同步,事件驱动优于请求-响应(在合适的场景下)

扩展性决策时:

  1. 先垂直扩展,再水平扩展
  2. 数据库是最难扩展的部分,提前规划
  3. 缓存不是架构,是创可贴 — 先修复根因
  4. 预留 10x 的扩展空间,但不要提前过度工程化

独立开发者特别建议

  • 简单性是你最大的武器
  • 用托管服务替代自建基础设施
  • Monolith first — 先用单体架构
  • 监控和可观测性从第一天就要有

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.
