fs-start

fs-start is a command for Claude Code from peterfei/ai-agent-team. It costs 25 tokens per session (439 once invoked), scanned A, original, MIT.

A command that creates a separate work thread and immediately starts a full-stack development task. Full-stack work covers both the part users see and the server-side code behind it.

In plain words
What is it for?
Use it for tasks that span a user interface and its backend, such as building registration, login, and profile features. Provide a task description after the command.
Why use it?
It keeps a substantial development task isolated from the current conversation while starting the work with the appropriate role and context.

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

fs-start 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

全栈开发 - 线程工作流

此命令会创建独立线程并立即以全栈开发工程师身份开始工作。

使用方法

/fs-start "开发用户认证功能,包括注册、登录、个人中心"

注意:请务必提供任务描述。请勿在输入 /fs-start 后直接回车,否则将创建无标题任务。


⚠️ 重要:执行流程

第1步:创建线程

调用 mcp__thread-manager__create_thread

{
  title: "[用户提供的任务标题]",
  description: "全栈开发任务 - [任务标题]",
  tags: ["fullstack", "fs"],
  switchTo: true
}

第2步:简洁通知

只输出一行

✨ 已创建全栈线程:"[标题]" (ID: [前8位])

第3步:立即开始全栈工作 ⭐

不要停止!立即切换到全栈开发角色并开始工作

  1. 读取 .claude/agents/fullstack_dev.md
  2. 以全栈开发工程师的身份和能力工作
  3. 输出完整的技术方案/代码实现(前后端一体化)
  4. 就像用户直接调用了 /fs [任务] 一样

示例

用户: /fs-start "开发用户认证功能"

Claude:
✨ 已创建全栈线程:"开发用户认证功能" (ID: abc12345)

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.
