Krow Agent SDK — extend the Krow agent engine with custom plugins, ACTs, tools, hints, gates and more.
Project description
krow-agent-sdk
让外部团队基于 Krow Agent 引擎扩展垂直场景应用,无需修改 Krow 主仓。
安装
pip install krow-agent-sdk # 最小核心(13 项依赖)
pip install "krow-agent-sdk[office]" # +24 项 docx/pptx/excel/pdf/Pillow 等
pip install "krow-agent-sdk[knowledge]" # +4 项 networkx/jieba 等
pip install "krow-agent-sdk[remote]" # +8 项 fastapi/uvicorn/websockets 等
pip install "krow-agent-sdk[all]" # 一站式全装
当前发布状态(2026-05-15):✅ 已上 PyPI 主站 —
pip install krow-agent-sdk即可装。 SDK 当前为 v0.8.x(Beta,API 稳定但持续迭代);详细路线 →roadmap.md。License 状态:本包受 End User License Agreement (EULA) v1.1 DRAFT 约束, 装包即同意(详见装机 site-packages 内的
LICENSE文件全文)。EULA EFFECTIVE 版本(含真律师签字)正在 review 中, 重大变更会以 30 天提前通知方式告知现有用户。完整公开文档 → https://github.com/aullik5/krow-sdk-docs(quickstart / plugin 协议 / EULA / roadmap)
5 分钟上手
from krow_agent_sdk import AgentBuilder
agent = (
AgentBuilder()
.with_krow_api_key("sk-...") # Krow Cloud API key(任何 sk- 前缀 + ≥20 字符;推荐 sk-user-)
.with_project_root("/path/to/your/project") # 项目根(agent 写文件的边界)
.with_chat_model("qwen3.6-plus") # chat 类别(可选;6 类按需指定)
.with_vision_model("qwen2.5-vl-72b-instruct") # vision (VLM) 类别(可选)
.build()
)
result = agent.run("帮我把 docs/ 下的 5 篇论文整理成 PPT")
print(result.final_output) # AgentV3Result 顶层的最终输出文本
agent.shutdown()
流式输出(实时事件 + 最终结果)
for item in agent.run_stream("帮我把 docs/ 下的 5 篇论文整理成 PPT"):
if item.kind == "event":
print(f"[{item.event.type}] {item.event.payload.get('summary', '')}")
elif item.kind == "result":
print("DONE:", item.result.final_output)
elif item.kind == "error":
raise item.error
agent.shutdown()
run_stream 返回 Iterator[StreamItem],3 种 kind:event(实时事件)/ result(最终结果)/ error(后台异常)。
默认订阅 macro_react.* / progressive.* / planner.* / react.* / llm.* / agent.task_*,可用 topics= 自定义(必须含 1 个终止 topic 防 stream 永挂)。

能力一览
| 维度 | 说明 |
|---|---|
| Plugin 协议(10+) | ACTPlugin / ToolPlugin / HintPlugin / GatePlugin / EventListenerPlugin / ObservabilityPlugin / MCPServerPlugin(form-A/B/C)/ SecurityPlugin / DomainPackPlugin / VisualAdapter |
| AgentBuilder API | .with_krow_api_key / .with_project_root / 6 个 .with_<category>_model(chat / reasoning / vision / image_gen / image_edit / text_encoder)/ .with_replay_store / .with_*_plugin 等链式构造 |
| Agent 执行 API | agent.run(...) 阻塞同步 / agent.run_stream(...) 流式 yield 事件 / agent.event_bus.subscribe(...) 自定义订阅 |
| LLM Record/Replay | krow_agent_sdk.replay.LLMReplayStore 让 plugin 测试零网络成本 |
| 诊断 / Read-only API | krow_agent_sdk.data / krow_agent_sdk.diagnostics 内省 Agent 状态 |
| Headless Docker | FROM krow-headless 直接拿到 SDK runtime |
版本号
SDK 版本号 = Krow 主仓 config/version.py:get_version() 动态读取(始终一致)。
当前主线版本:0.8.x。
发布 tag 约定(参考,最终以 GitHub Releases 为准):
sdk-v0.8.x— 公开 SDK wheel(PyPIkrow-agent-sdk)runtime-v0.8.x— 私有 runtime wheel(私有 indexkrow-agent-sdk-runtime)v0.8.x-lite/v0.8.x-full— 桌面应用 release(与 SDK 同步号)
