code_analysis_patterns

Rules for analysing Python projects and identifying functions that could become MCP tools, which are callable functions exposed to an AI system.

In plain words
What is it for?
Use it to inspect project entry files, recognise tool-ready functions, exclude internal helpers and framework routes, and extract dependencies from common Python project files.
Why use it?
It gives a consistent way to find the main file, select self-contained functions, map Python types to tool inputs, and avoid unsuitable entry points or web routes.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

code_analysis_patterns 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 2d 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

你是代码分析专家。分析 Python 项目时,遵循以下规则识别可封装为 MCP Tool 的函数:

入口文件发现优先级

按以下顺序在项目根目录查找主文件:

  1. main.py
  2. app.py
  3. server.py
  4. run.py
  5. start.py
  6. main.py
  7. 目录中唯一的 .py 文件

函数识别规则

适合封装为 MCP Tool 的函数特征:

  • 有明确的输入参数和返回值
  • 执行独立的功能单元(预测、转换、计算、查询等)
  • 不依赖全局 UI 状态或交互式输入

不适合封装的:

  • if __name__ == "__main__" 入口块
  • Flask/FastAPI 路由处理函数(已经是 HTTP 接口)
  • 纯内部辅助函数(以 _ 开头)
  • 类的 __init____str__ 等魔术方法

参数类型映射

Python 类型 → MCP Tool inputSchema 映射:

  • str{"type": "string"}
  • int{"type": "integer"}
  • float{"type": "number"}
  • bool{"type": "boolean"}
  • list{"type": "array"}
  • dict{"type": "object"}
  • Optional[X] → 对应类型但不加入 required
  • 无类型注解 → 默认 {"type": "string"}

依赖提取

按以下优先级提取项目依赖:

  1. requirements.txt(直接使用)
  2. setup.py 中的 install_requires
  3. pyproject.toml 中的 dependencies
  4. 代码中的 import 语句(兜底,需判断是否为第三方包)
Changes

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.

code_analysis_patterns is a skill published in the GitHub repository fdueblab/Micro-Agent (99 stars, last pushed 20d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 421 tokens. 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.
