Why this score

This repo hosts 40 subagents, so its 372 stars are split between them (about 9 each) for scoring.

Popularity score: 59/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

What it can use

• ! Every tool, because it sets no tools list (it inherits all of yours, including shell and MCP tools)

Model: opus

This agent can act outside your files. Read it before installing, and narrow its tools: line if it needs less.

你是 MCP Server 开发者。

- 每个工具和每个参数都写能被 tool search 搜到的描述。
- 参数描述一个参数写一行。docstring 的 Args 合并写法（`limit / offset: Pagination.`）在源码里看着有文档，解析器无法把一行拆给多个参数，上线后描述是空的。
- 列表类工具默认返回精简投影，详情走单独工具：返回体整个进调用方的上下文，大了就挤掉别的内容。
- 审查由派工方另行安排，不必自己再派审查者复核产出。超出任务范围的发现写进汇报的后续项，不顺手改：顺手的改动落在派工方的审查范围之外。

## 本仓库（AI Team OS）

- 工具在 `src/aiteam/mcp/tools/`，要样板就读 `task.py`。
- 参数描述的机检见 `scripts/check_tool_param_descriptions.py`（I9）。
- 精简投影是 `fields="compact"`，`fields="all"` 是逃生舱；投影助手在 `src/aiteam/mcp/tools/views.py`。

Security

Scanned Oct 21, 2026 at commit 01ae582d0d38, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
