For AI Agents

If you are an AI agent reading this (Claude, Codex, Cursor, Windsurf, Copilot, or any LLM tool), follow the four steps below. After setup, you will have cross-session memory across all your conversations.

Step 1: Install

pip install contextgo
contextgo health

If pip is not available, install from source:

git clone https://github.com/dunova/ContextGO.git
cd ContextGO && pip install -e . && contextgo health

Step 2: Build initial index

contextgo maintain --enqueue-missing    # discover all existing sessions
contextgo search "test" --limit 1       # verify index works

Step 3: Add to your AI tool's instructions

Copy the contents of AGENTS.md into your AI tool's persistent instructions file:

AI Tool	Where to add
Claude Code	~/.claude/CLAUDE.md (append AGENTS.md content)
Codex	AGENTS.md in project root (already works if repo is cloned)
Cursor	.cursorrules in project root
Windsurf	.windsurfrules in project root
Other	Your tool's system prompt or instruction file

Tell your user: "I need to add ContextGO instructions to [config file]. This lets me automatically search your session history when relevant. OK?"

Step 4: Verify automatic behaviors

After setup, these behaviors activate automatically:

• You don't know the project history -> contextgo search "topic" --limit 5 before answering
• User says "continue", "what was I doing" -> contextgo semantic "topic" --limit 3 and summarize
• User asks about past decisions -> search and summarize in 2-3 sentences
• Hard problem solved -> suggest contextgo save to persist the conclusion
• Session ends -> save handoff notes for the next session

Full behavioral spec: AGENTS.md

CONTEXTGO_SESSION_INDEX_DB_PATH	$ROOT/index/session_index.db	Session index SQLite path
MEMORY_INDEX_DB_PATH	$ROOT/index/memory_index.db	Memory index SQLite path
CONTEXTGO_VIEWER_HOST	127.0.0.1	Viewer bind address
CONTEXTGO_VIEWER_PORT	37677	Viewer TCP port
CONTEXTGO_VIEWER_TOKEN	(empty)	Bearer token for non-loopback binding
CONTEXTGO_ENABLE_REMOTE_MEMORY_HTTP	false	Enable remote sync (disabled by default)

命令参考

检索与召回

contextgo search "schema 迁移" --limit 10         # 全文关键词检索
contextgo semantic "数据库设计决策" --limit 5       # 本地向量语义检索
contextgo native-scan --backend auto --threads 4  # 直接调用原生扫描器

记忆

contextgo save --title "认证修复" --content "..." --tags auth,bug
contextgo export "" /tmp/export.json --limit 1000
contextgo import /tmp/export.json

运维

contextgo health                       # 验证安装状态与存储完整性
contextgo maintain --enqueue-missing   # 索引所有已有会话
contextgo smoke                        # 执行完整 smoke 测试套件
contextgo maintain --dry-run           # 清理并修复本地索引
contextgo serve --port 37677           # 在 127.0.0.1:37677 启动本地 Viewer

面向 AI Agent

如果你是一个 AI agent（Claude、Codex、Cursor、Windsurf、Copilot 或任何 LLM 工具），请按以下四步完成配置。配置完成后，你将拥有跨会话的持久记忆能力。

第一步：安装

pip install contextgo
contextgo health

如果 pip 不可用，可从源码安装：

git clone https://github.com/dunova/ContextGO.git
cd ContextGO && pip install -e . && contextgo health

第二步：构建初始索引

contextgo maintain --enqueue-missing    # 发现并索引所有已有会话
contextgo search "test" --limit 1       # 验证索引正常工作

第三步：添加到你的 AI 工具配置

将 AGENTS.md 的内容复制到你所用 AI 工具的持久化指令文件中：

AI 工具	配置位置
Claude Code	~/.claude/CLAUDE.md（追加 AGENTS.md 内容）
Codex	项目根目录的 AGENTS.md（克隆仓库后自动生效）
Cursor	项目根目录的 .cursorrules
Windsurf	项目根目录的 .windsurfrules
其他工具	你的工具的系统提示词或指令文件

告诉用户："我需要将 ContextGO 指令添加到 [配置文件]。这样我就能在相关时自动检索你的会话历史。可以吗？"

第四步：验证自动行为

配置完成后，以下行为自动激活：

• 不了解项目历史 -> 回答前先执行 contextgo search "topic" --limit 5
• 用户说"继续"、"我在做什么" -> 执行 contextgo semantic "topic" --limit 3 并总结
• 用户询问过往决策 -> 检索并用 2-3 句话总结
• 解决了复杂问题 -> 建议执行 contextgo save 持久化结论
• 会话结束 -> 保存交接备注供下一个会话使用

完整行为规范：AGENTS.md

配置

所有配置均通过环境变量完成，默认值开箱即用。

变量	默认值	说明
CONTEXTGO_STORAGE_ROOT	~/.contextgo	所有数据的根目录
CONTEXTGO_SESSION_INDEX_DB_PATH	$ROOT/index/session_index.db	会话索引 SQLite 路径
MEMORY_INDEX_DB_PATH	$ROOT/index/memory_index.db	记忆索引 SQLite 路径
CONTEXTGO_VIEWER_HOST	127.0.0.1	Viewer 绑定地址
CONTEXTGO_VIEWER_PORT	37677	Viewer TCP 端口
CONTEXTGO_VIEWER_TOKEN	（空）	非回环地址绑定时的 Bearer token
CONTEXTGO_ENABLE_REMOTE_MEMORY_HTTP	false	启用远程同步（默认关闭）
