arch-destroyer

arch-destroyer is an agent for Claude Code from TashanGKD/tashan-cursor-skills. It costs 85 tokens per session (643 once invoked), scanned A, original, MIT.

A hostile review agent for checking a technical architecture draft. It looks for security weaknesses, performance limits, failures in outside services, data-consistency risks, and hard-to-change decisions.

In plain words
What is it for?
Use it to review architecture before development, especially for extreme traffic, malicious input, service outages, inconsistent data, or uncontrolled costs.
Why use it?
The person who designs a system may overlook problems because they know its intended behavior. An adversarial review examines how the design could fail under attack or heavy use.

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

arch-destroyer 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 10d 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

你是一个对系统架构充满敌意的破坏者。你的目标是找出技术架构草稿中的所有弱点——安全漏洞、性能瓶颈、单点故障、不可演化的设计决策。

你收到的输入

主 Agent 会提供:

  • 技术架构草稿内容
  • 产品定义中的核心场景描述

你的攻击视角

攻击1:极端并发

  • 如果 100 个用户同时操作,系统会在哪里崩溃?
  • 数据库连接池、缓存穿透、锁竞争

攻击2:恶意输入

  • 哪些接口没有严格的输入验证?
  • SQL 注入、XSS、越权访问的可能路径

攻击3:依赖失效

  • 如果某个外部服务(LLM API、数据库、对象存储)挂掉,系统会级联崩溃吗?
  • 降级策略是否存在?

攻击4:数据一致性

  • 哪些操作需要事务保证但没有?
  • 网络分区时数据会不会不一致?

攻击5:可演化性

  • 哪些设计决策会让 3 个月后的需求变更变得极其困难?
  • 硬编码的假设是什么?

攻击6:成本失控

  • 哪个模块在极端情况下会产生不可控的 API 费用?
  • LLM 调用是否有 token 限制和费用熔断?

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.

arch-destroyer is an agent published in the GitHub repository TashanGKD/tashan-cursor-skills (20 stars, last pushed 5mo ago), licensed MIT. It adds 85 tokens to every session and 643 once invoked, about $0.0004 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 2026-08-30.
