[tanyouqing]

Description

Adds a unified OpenCode plugin package for OpenViking. The plugin merges repository retrieval and long-term memory capabilities into a package-style OpenCode plugin that can be enabled through OpenCode's plugin configuration.

⚡ Recommended focus areas for review Incorrect file extension for ESM wrapper The wrapper file uses ESM syntax (export) but has a .js extension. When placed in the OpenCode plugins directory (which lacks a package.json with "type": "module"), Node.js will interpret it as CommonJS and throw a syntax error. The file should be renamed to .mjs. export { OpenVikingPlugin, default } from "./openviking/index.mjs" Documentation consistent with wrapper file extension INSTALL.md correctly references openviking.mjs, but the actual file is named openviking.js. After renaming the wrapper to .mjs, verify all docs are consistent. cp examples/opencode-plugin/wrappers/openviking.mjs ~/.config/opencode/plugins/openviking.mjs Documentation uses wrong wrapper extension INSTALL-ZH.md references openviking.js, but the wrapper should use .mjs for ESM compatibility. Update the documentation to use .mjs after renaming the wrapper file. mkdir -p ~/.config/opencode/plugins/openviking cp examples/opencode-plugin/wrappers/openviking.js ~/.config/opencode/plugins/openviking.js

整体方向 +1，分层清晰，工具语义也设计得到位。merge 前几个 must-fix，后面是建议。

🔴 必修

1. wrappers/openviking.js 必须改成 .mjs，INSTALL.md 同步更新。
   ~/.config/opencode/plugins/ 默认没有 package.json，那里的 .js 走 CJS 解析，export { ... } from 直接 SyntaxError。package.json 里 "check": "node --check wrappers/openviking.js" 也要跟着改。

2. INSTALL.md / INSTALL-ZH.md L60-62 那段开发期残留要清理。

   \\If it cannot be loaded automatically, try running it manually:
   cd D:\OV-intern\ov-plugins-merge\.opencode\plugins
   

   \\If 是错别字，D:\OV-intern\... 是作者本机路径，不能进发布文档。

3. README.md / INSTALL.md 声称"替换了 examples/opencode/ 和 examples/opencode-memory-plugin/"，但 PR 没删旧目录。
   要么这个 PR 一起删旧目录，要么把"replaces"文案改成"新增统一插件，旧示例后续会下线"。文档和代码必须一致，否则用户不知道该装哪个。

4. package.json 的 files 列了不存在的 README_ZH.md。
   仓库里只有 INSTALL-ZH.md，没有 README_ZH.md。npm pack 会丢中文 README。要么改名，要么从 files 删掉。

5. @opencode-ai/plugin: "latest" 锁到具体版本。
   latest 影响重现性、有供应链风险。改成 ^x.y.z。

🟡 强烈建议

6. makeAuthHeaders 改用 Authorization: Bearer。
   Server 两种都吃，但 Bearer 是更通用的标准头，也方便后面统一鉴权链路。

7. mergeConfig 加 OPENVIKING_URL / OPENVIKING_ENDPOINT env 覆盖。
   现在只 cover 了 apiKey/account/user/agentId，endpoint 是漏的。

8. memory-recall.mjs 的 token 抽取支持 CJK。
   RECALL_TOKEN_RE = /[a-z0-9]{2,}/gi 不匹配中文，中文 query 进 lexicalOverlapBoost 永远返回 0，这条路径对中文用户是死代码。
   建议：/[\p{Script=Han}]+|[a-z0-9]{2,}/giu + 加几个中文停用词。
   （PREFERENCE_QUERY_RE / TEMPORAL_QUERY_RE 已经支持中文，这部分 OK。）

9. session.created 时 repoContext.refreshRepos({ force: true }) 改成 force: false。
   现在每开一个新 session 都强制绕过 TTL 重拉一次，没必要，TTL 自然兜就行。

10. memsearch 返回结果别全 JSON.stringify。
    formatSearchResults 当前把 memories + resources + skills 完整序列化，包含 content 字段，20 条结果容易爆 LLM context。设计意图是让 LLM 用 memread 取详情，所以 search 返回里只保留 uri / title / abstract 就够了。

11. flushPendingMessages "内容更新"分支会导致重复入库（memory-session.mjs ~L285-292）。
    send 期间 stream chunk 进来时，旧版本已经成功 POST 了但因为 latest !== content 命中 continue、跳过 capture 标记，下一轮 flush 会用新内容再发一次，同 messageId 不同 content 在 OV 那边形成重复消息。要么加注释明确这是预期行为，要么改成"接受 latest 作为下一轮种子"。

12. makeRequest / makeMultipartRequest 的 401/403 分支把 server 真实错误抹掉了。
    trusted mode 下"Missing X-OpenViking-Account"这种具体信息直接看不到，debug 困难。建议拼上 errorMessage：Authentication failed (${errorMessage}). Check apiKey/account/user...

13. 加几个单测。
    mergeMessageContent 的合并语义、memory-recall 的排序 / 去重 / token boost 都是会出 corner case 的地方，2400 行代码 0 测试有点慌。

💡 架构层面（不阻塞合并，可开 follow-up）

读侧工具（memsearch / memread / membrowse / memgrep / memglob）长期建议复用 OV 自带 MCP，plugin 只保留 OpenCode event 必须做的事——session 映射、消息流捕获、auto-commit、auto-recall。这样跨客户端（Claude Code / OpenCode / Cursor / Codex）工具表一致，server 升级新工具 plugin 不用跟版本。memadd 的本地上传可以接上 #1847 的 progressive upload 流程。

Nice work merging the split plugins into one unified package. Two suggestions:

1. Remove autoStartServer — the plugin should only take an endpoint URL + API key. Decoupling from server lifecycle is cleaner and avoids the detached-process management problem (no PID tracking / no shutdown).

2. Wrapper path assumption — wrappers/openviking.mjs exports from "./openviking/index.mjs", which assumes the source-install directory layout. This will break when installed as an npm package. Consider adjusting or documenting the constraint.

Otherwise the architecture is solid — native OpenCode plugin API (event/tool/system.transform/messages.transform) is the right call over the shell-hook approach.

[ZaynJarvis]

One more — the 10-minute auto-commit interval may not be the best trigger. Memories are already in the session context while the conversation is alive. Committing on a timer wastes cycles when context is intact. Consider committing only at context-loss boundaries (session end, compaction, context window pressure) instead of on a fixed interval.
