dsh-experience
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@dsh-experienceHow did I solve git push TLS timeout before?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
dsh-experience
一个跨会话经验知识库(自主进化)。它把 agent 在任务中踩过的坑、探索出的解决方案, 沉淀成可复用的"问题 → 解决方案"经验,让模型在新会话遇到类似问题时检索并复用—— 不重新训练,越用越强。
对应前沿:WebCoach(arXiv 2511.12997)的跨会话记忆三组件;Evo-Memory 的 test-time evolution 思想。数据源是 DSH 已有的 session 日志。
三组件(对应 WebCoach)
组件 | 文件 | 作用 |
Condenser(压缩) |
| 把会话轨迹压缩成"问题→解决方案"经验(离线,用 flash) |
Memory Store(存储) |
| 持久化经验库 |
Coach(检索) |
| 新会话遇到问题,检索相关经验(零 LLM) |

核心原则
运行时零 LLM:检索默认是纯词法(IDF 加权 + 中文 bigram),查询时不花任何 token;
可选本地语义检索:启动本地 embedding 服务(见下)后,检索升级为语义匹配 (bge-large-zh,本地 GPU/CPU,零云端成本),解决同义词/表述差异;服务未启动时 自动降级词法;
离线才用大模型:只有
extract.mjs提取经验时调 flash(批量、事后);自主进化:
extract.mjs+add_experience持续沉淀,库随任务增长;重复经验自动去重。
语义检索(可选,本地 embedding)
缓存里若已有 BAAI/bge-large-zh-v1.5(或联网可下载),启动本地服务:
python embed-server.py # 默认 127.0.0.1:8001,需 transformers+torchstore.mjs 检测到该服务后,检索从"词法"自动升级为"语义"(bge 中文 embedding +
query/doc 分离 + 余弦相似度,阈值 0.45 过滤无关,recency 微调);服务挂了则回退词法。
用法
1. 离线提取经验(唯一用大模型的地方)
node extract.mjs --latest # 从最新会话提取
node extract.mjs --all # 从所有会话提取
node extract.mjs <sessionDir> # 指定会话目录2. 运行时检索(MCP 工具)
把 index.mjs 挂进 DSH(见下方),agent 遇到问题时可调:
mcp__experience__search_experience("git push GitHub TLS 超时怎么办")
→ 返回过去会话里解决过这个问题的经验其余工具:add_experience(手动沉淀)、list_experiences(浏览)。
挂进 DSH
在 cordis.patch.yml 的 insert: 里加:
- id: mcp-experience
name: '@deepseek-ai/dsh-mcp-client'
config:
serverName: experience
transport: stdio
command: '<node 路径>'
args:
- '<本目录>/index.mjs'经验条目结构
{
"id": "…",
"problem": "问题一句话",
"solution": "解决方案(含命令/文件/配置细节)",
"keywords": ["关键词"],
"sourceSession": "session-…",
"createdAt": "ISO"
}诚实局限
"Coach mode" 自动注入尚未实现:当前是"工具触发"检索——agent 遇到问题时主动调
search_experience。完整闭环("工具失败 → 自动检索 → 注入短暂建议 → 成功后提取")需要 harness hook(execute.after/PostToolUseFailure),尚未接入;并发:写入已用进程内锁 + 原子改名 + 唯一临时名,单进程安全;但多进程共享同一份
experience.jsonl仍可能丢更新,生产级应换成 SQLite + WAL;语义检索依赖本地 Python 服务:
embed-server.py(bge-large-zh)未启动时自动降级为词法, 但词法对同义改写、跨语言召回弱;本地 embedding 服务有部署门槛;提取用 flash:
extract.mjs离线批量提取时调 DeepSeek flash,提取质量受模型能力限制; 且只在成功恢复后提取才有意义——失败的尝试不该污染经验库。
测试
node test.mjs(分词 / 检索 / 持久化 / 并发写不丢更新)。
