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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.00401 |
| Opus 5.5 | $0.00009 | $0.00160 |
| Sonnet 5.5 | $0.00004 | $0.00080 |
| Haiku 4.5 | $0.00002 | $0.00040 |
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 1mo 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：
- 读取
.claude/agents/backend_dev.md - 以后端开发工程师的身份和能力工作
- 输出完整的技术方案/代码实现
- 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.
- 1mo ago First seen · 78 lines · 0 tokens per session scan A 326d0e303523
be-start is a command published in the GitHub repository peterfei/ai-agent-team (448 stars, last pushed 4mo ago), licensed MIT. It adds 22 tokens to every session and 401 once invoked, about $0.0001 per session on Opus 5.5. 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.
