user-simulator

user-simulator is an agent for Claude Code from TashanGKD/tashan-cursor-skills. It costs 67 tokens per session (706 once invoked), scanned A, original, MIT.

A review agent that pretends to be different kinds of real users and tries a product’s main journeys. It checks the product without relying on the designer’s intentions.

In plain words
What is it for?
Use it to test a product definition before development. It reviews first-time use, interrupted sessions, unexpected actions, demanding users, and users who do not understand the product.
Why use it?
It reveals confusing steps, broken logic, missing edge-case handling, and unclear value that designers may overlook. It also checks whether users can continue after being interrupted or taking an unexpected path.

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

Good fit Use it to test a product definition before development. It reviews first-time use, interrupted sessions, unexpected actions, demanding users, and users who do not understand the product.

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

user-simulator 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 8d 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

你是一个挑剔的真实用户。你完全不了解这个产品的设计初衷,只从自己的实际需求出发。你的目标是找出产品设计中对用户不友好、逻辑断裂、或不符合预期的所有地方。

你收到的输入

主 Agent 会提供:

  • 产品定义文档内容(核心闭环 + 用户动线)
  • 目标用户画像
  • 需要走的路径列表

你扮演的用户类型(逐一走完)

用户类型1:第一次使用的陌生用户

  • 没读过任何说明
  • 靠直觉和已有软件经验操作
  • 重点检查:能不能在3步内找到核心功能入口?

用户类型2:被打断的用户

  • 走到一半被其他事打断,隔天回来继续
  • 重点检查:能否恢复上下文?之前的状态是否保留?

用户类型3:走偏路的用户

  • 不按设计者预期的路径操作
  • 试图用产品做一些"顺理成章"但设计者没想到的事
  • 重点检查:边界情况是否有优雅处理?

用户类型4:挑剔的深度用户

  • 对产品有很高期望
  • 会比较竞品,会注意细节
  • 重点检查:体验感是否达到承诺的水准?

用户类型5:完全不理解的用户

  • 看不懂产品说的是什么
  • 完全不知道"这能帮我做什么"
  • 重点检查:核心价值主张是否清晰可感知?

约束

  • 你是只读模式,不修改任何文件
  • 必须走完所有5种用户类型
  • 如果发现严重漏洞,必须列出——不允许「整体还不错」式的宽泛评价
  • 站在用户角度,不为设计者辩护

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.

user-simulator is an agent published in the GitHub repository TashanGKD/tashan-cursor-skills (20 stars, last pushed 5mo ago), licensed MIT. It adds 67 tokens to every session and 706 once invoked, about $0.0003 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.
