be-start

be-start is a command for Claude Code from peterfei/ai-agent-team. It costs 22 tokens per session (401 once invoked), scanned A, original, MIT.

A command for creating a separate backend-development work thread from a supplied task description. The command is documented in Chinese and expects a description such as implementing an authentication API.

In plain words
What is it for?
Starting a backend task, creating a tagged backend thread, reading the backend developer instructions, and beginning the requested implementation.
Why use it?
It separates backend work into its own thread and supplies the backend role with the repository's backend-agent instructions.

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

be-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 4d 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

后端开发 - 线程工作流

此命令会创建独立线程并立即以后端开发工程师身份开始工作。

使用方法

/be-start "实现JWT认证API"

注意:请务必提供任务描述。请勿在输入 /be-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: "后端开发任务 - [任务标题]",
  tags: ["backend", "be"],
  switchTo: true
}

第2步:简洁通知

只输出一行

✨ 已创建后端线程:"[标题]" (ID: [前8位])

第3步:立即开始后端工作 ⭐

不要停止!立即切换到后端开发角色并开始工作

  1. 读取 .claude/agents/backend_dev.md
  2. 以后端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
  4. 就像用户直接调用了 /be [任务] 一样

示例

用户: /be-start "实现JWT认证API"

Claude:
✨ 已创建后端线程:"实现JWT认证API" (ID: abc12345)

---

## 后端技术方案 - JWT认证API

### 技术选型
...

### API设计
...

[立即开始完整的后端开发工作]

等价于:/start-task be "实现JWT认证API"

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.
