+# Eino ADK Multiagent Example: OpenClaw-like Agent
+
+## Description
+`openclaw-like-agent` is a workspace-aware local agent example built on Eino ADK.
+
+This example is a reproduction of the recent OpenClaw-style local agent experience using Eino ADK. It shows how to build an OpenClaw-inspired agent pattern with Eino primitives, while keeping the project structure consistent with the other examples in this repository.
+
+Compared with the other `adk/multiagent` demos, this example is closer to a practical local assistant:
+
+- It starts from a standard `main.go` entry and can be launched directly with `go run`.
+- It keeps multi-turn conversation history by `session`.
+- It creates and manages a dedicated `workspace`.
+- It supports loading skills from multiple directories.
+- It exposes filesystem and shell capabilities through a restricted backend.
+
+The current implementation is organized as a CLI application, with the main logic living under the `myagent` package.
+
+## Env
+Before running it, configure the model-related environment variables:
+
+```bash
+# Required
+export OPENAI_API_KEY=""
+export OPENAI_MODEL=""
+
+# Optional
+export OPENAI_BASE_URL=""
+export OPENAI_BY_AZURE="false"
+```
+
+## Quick Start
+Start interactive chat mode:
+
+```bash
+go run ./adk/multiagent/openclaw-like-agent
+```
+
+Run one single-turn query:
+
+```bash
+go run ./adk/multiagent/openclaw-like-agent -- run -q "帮我总结当前 workspace 里有哪些文件"
+```
+
+Use a fixed workspace and session:
+
+```bash
+go run ./adk/multiagent/openclaw-like-agent -- \
+  --workspace /tmp/myagent-demo \
+  --session-id demo \
+  chat
+```
+
+Example interactive output with sensitive information masked:
+
+```text
+$ go run main.go
+MyAgent TUI
+workspace: /path/to/eino-examples/adk/multiagent/openclaw-like-agent/myagent_workspace
+session:   sess_xxxxxxxxxxxxxxxx
+commands:  /help /session /history /clear /exit
+
+myagent> 你好
+
+[00:15:09] user> 你好
+[run.started] session=sess_xxxxxxxxxxxxxxxx workspace=/path/to/eino-examples/adk/multiagent/openclaw-like-agent/myagent_workspace
+[assistant] 你好！很高兴见到你。有什么我可以帮你的吗？
+
+[run.completed] session=sess_xxxxxxxxxxxxxxxx saved_messages=2 at=00:15:12
+
+myagent>
+```
+
+## CLI Commands
+The root command defaults to interactive chat mode, and also provides several subcommands:
+
+- `chat`: interactive chat mode.
+- `run [-q query] [query]`: execute one turn only.
+- `session list`: list all sessions in the current workspace.
+- `session clear --session-id <id>`: clear conversation history and summary for one session.
+- `session delete --session-id <id>`: delete the persisted files for one session.
+- `skill list`: list all discovered skills.
+
+Common flags:
+
+- `--workspace`, `-w`: workspace directory. Default is `./myagent_workspace`.
+- `--session-id`: session id. Auto-generated when omitted.
+- `--instruction`: override the default system instruction.
+- `--max-iterations`: max loop iterations for the agent.
+
+## Interactive Commands
+In `chat` mode, the following slash commands are supported:
+
+- `/help`
+- `/skills`
+- `/session`
+- `/history`
+- `/clear`
+- `/exit`
+
+## Workspace Layout
+When the agent starts for the first time, it will initialize the workspace automatically:
+
+```text
+myagent_workspace/
+├── IDENTITY.md
+├── artifacts/
+├── logs/
+├── memory/
+│   └── MEMORY.md
+├── sessions/
+└── skills/
+```
+
+Key files and directories:
+
+- `IDENTITY.md`: workspace-level identity override.
+- `memory/MEMORY.md`: long-term memory.
+- `sessions/`: persisted session metadata and message history.
+- `skills/`: workspace-local skills.
+- `artifacts/`: files generated during execution.
+- `.claude/skills/`: optional skill directory under the workspace. It is supported by the loader, but not created automatically.
+
+## Skill Loading Order
+The agent currently loads skills in the following priority order:
+
+1. `<workspace>/skills`
+2. `<workspace>/.claude/skills`
+3. `~/.claude/skills`
+4. `$XDG_CONFIG_HOME/myagent/skills` or `~/.config/myagent/skills`
+5. builtin skills directory, defaulting to `./skills`
+
+You can inspect discovered skills with:
+
+```bash
+go run ./adk/multiagent/openclaw-like-agent -- skill list
+```
+
+## Notes
+- The backend is workspace-restricted by default and protects key files such as `IDENTITY.md` and `MEMORY.md`.
+- Session history is stored as JSONL under `sessions/`.
+- This example has already been wired into the repository as a standard sub-application entry and can be built directly with:
+
+```bash
+go build ./adk/multiagent/openclaw-like-agent
+```

+# Eino ADK 多智能体示例：OpenClaw-like Agent
+
+## 简介
+`openclaw-like-agent` 是一个基于 Eino ADK 构建的、本地运行的 workspace 感知型 Agent 示例。
+
+这个示例可以理解为基于 Eino ADK 对近期很火的 OpenClaw 风格本地 Agent 体验做的一次复刻。它展示了如何用 Eino 提供的 Agent、工具、session 和 workspace 能力，搭建出一个 OpenClaw 风格的本地 Agent 形态，同时保持与本仓库其他示例一致的项目结构。
+
+和其他 `adk/multiagent` 示例相比，这个例子更接近一个可实际使用的本地助手，也更贴近近期 OpenClaw 风格本地 Agent 的使用方式：
+
+- 通过标准 `main.go` 入口启动，可直接使用 `go run` 运行。
+- 支持基于 `session` 的多轮对话历史持久化。
+- 自动创建并管理独立的 `workspace`。
+- 支持从多个目录加载 skills。
+- 通过受限 backend 暴露文件系统与 shell 能力。
+
+当前实现是一个 CLI 应用，核心逻辑位于 `myagent` 包中。
+
+## 环境变量
+运行前请先配置模型相关环境变量：
+
+```bash
+# 必填
+export OPENAI_API_KEY=""
+export OPENAI_MODEL=""
+
+# 可选
+export OPENAI_BASE_URL=""
+export OPENAI_BY_AZURE="false"
+```
+
+## 快速开始
+启动交互式聊天模式：
+
+```bash
+go run ./adk/multiagent/openclaw-like-agent
+```
+
+执行单轮请求：
+
+```bash
+go run ./adk/multiagent/openclaw-like-agent -- run -q "帮我总结当前 workspace 里有哪些文件"
+```
+
+指定固定的 workspace 和 session：
+
+```bash
+go run ./adk/multiagent/openclaw-like-agent -- \
+  --workspace /tmp/myagent-demo \
+  --session-id demo \
+  chat
+```
+
+脱敏后的交互示例：
+
+```text
+$ go run main.go
+MyAgent TUI
+workspace: /path/to/eino-examples/adk/multiagent/openclaw-like-agent/myagent_workspace
+session:   sess_xxxxxxxxxxxxxxxx
+commands:  /help /session /history /clear /exit
+
+myagent> 你好
+
+[00:15:09] user> 你好
+[run.started] session=sess_xxxxxxxxxxxxxxxx workspace=/path/to/eino-examples/adk/multiagent/openclaw-like-agent/myagent_workspace
+[assistant] 你好！很高兴见到你。有什么我可以帮你的吗？
+
+[run.completed] session=sess_xxxxxxxxxxxxxxxx saved_messages=2 at=00:15:12
+
+myagent>
+```
+
+## CLI 命令
+根命令默认进入交互式聊天模式，同时也提供以下子命令：
+
+- `chat`：进入交互式聊天模式。
+- `run [-q query] [query]`：执行单轮请求。
+- `session list`：列出当前 workspace 下的全部 session。
+- `session clear --session-id <id>`：清空某个 session 的历史和摘要。
+- `session delete --session-id <id>`：删除某个 session 的持久化文件。
+- `skill list`：列出当前可发现的所有 skills。
+
+常用参数：
+
+- `--workspace`, `-w`：指定 workspace 目录，默认是 `./myagent_workspace`。
+- `--session-id`：指定 session id；不传时自动生成。
+- `--instruction`：覆盖默认 system instruction。
+- `--max-iterations`：Agent loop 的最大迭代次数。
+
+## 交互模式命令
+在 `chat` 模式下，支持以下 slash commands：
+
+- `/help`
+- `/skills`
+- `/session`
+- `/history`
+- `/clear`
+- `/exit`
+
+## Workspace 目录结构
+首次启动时，Agent 会自动初始化 workspace：
+
+```text
+myagent_workspace/
+├── IDENTITY.md
+├── artifacts/
+├── logs/
+├── memory/
+│   └── MEMORY.md
+├── sessions/
+└── skills/
+```
+
+主要目录和文件说明：
+
+- `IDENTITY.md`：workspace 级别的 identity 覆盖文件。
+- `memory/MEMORY.md`：长期记忆文件。
+- `sessions/`：session 元数据与消息历史持久化目录。
+- `skills/`：workspace 本地 skills 目录。
+- `artifacts/`：执行过程中产生的产物文件目录。
+- `.claude/skills/`：workspace 下可选的 skill 目录，loader 支持读取，但不会自动创建。
+
+## Skill 加载顺序
+当前 Agent 按如下优先级加载 skills：
+
+1. `<workspace>/skills`
+2. `<workspace>/.claude/skills`
+3. `~/.claude/skills`
+4. `$XDG_CONFIG_HOME/myagent/skills` 或 `~/.config/myagent/skills`
+5. 内置 skills 目录，默认是 `./skills`
+
+你可以用下面的命令查看最终发现的 skills：
+
+```bash
+go run ./adk/multiagent/openclaw-like-agent -- skill list
+```
+
+## 说明
+- backend 默认限制在 workspace 范围内运行，并保护 `IDENTITY.md`、`MEMORY.md` 等关键文件。
+- session 历史会以 JSONL 形式持久化到 `sessions/` 目录。
+- 这个示例已经作为标准子应用接入仓库，可以直接编译：
+
+```bash
+go build ./adk/multiagent/openclaw-like-agent
+```
