agentsop-repo-state-gating

A 5-minute gate the coder runs at project kickoff (and again whenever the repo shape changes). Classifies the workspace into Greenfield / Brownfield-large / Mid-size-familiar / Library-SDK, then maps the state to an agent strategy (autonomy, context primitive, tool choice). Use BEFORE picking Cursor vs Claude Code vs Aider, BEFORE turning on repo-map, BEFORE writing the first prompt. Skip only if the same repo was gated within the last day and nothing changed. Search keywords: greenfield vs brownfield, new project vs existing codebase, project setup strategy, legacy codebase agent, where to start a coding agent.

# Repo-State Gating — 5-Line Decision at Project Kickoff

> 一句话:**agent strategy = f(repo-state)**。先判定 repo 状态,再选工具/上下文原语/自治程度。
> 跳过这一步 = 用错工具,浪费一个小时的上下文。

## 1. 何时激活

只在以下时刻跑一次(≤5 分钟):

- **新会话第一次进入某仓库**(含 `cd` 切到新目录、`git clone` 后第一次启动 agent)
- **仓库形态显著变化**:从空目录跑到 100+ 文件、引入新子系统、merge 一个大 PR
- **agent 选错过工具**之后的复盘("我为什么开了 Cursor 写 SDK / 用 Aider 起新项目")
