DeepSeek Harness plugin: Claude-Code-style lifecycle hooks for DSH. Configure shell commands that run automatically before/after model tool calls (pre-tool / post-tool) with a JSON payload on stdin; pre-tool non-zero exits block the call.

tools/pre-execute / tools/post-execute 两个有序 waterfall,以及 shell 服务"通过 stdin 给命令喂 JSON payload"的词汇表(见 @deepseek-ai/dsh-shell)。这个插件以纯外部插件形式补上这块空白,设计对齐官方预留接口: - pre-tool hook:匹配的工具执行前运行;命令非零退出 → 阻止该工具调用(等价 Claude Code PreToolUse 返回 error); - post-tool hook:工具结果落地后运行;退出码只记录,不改变工具结果。 ## 配置 JSON 配置,来源二选一或叠加: 1. 文件(默认 $DSH_HOME/hooks.json): json { "hooks": [ { "id": "lint-after-edit", "event": "post-tool", "tools": ["edit", "write"], "command": "npm run lint -- --quiet", "timeoutMs": 30000 }, { "id": "guard-prod", "event": "pre-tool", "tools": ["bash", "pwsh"], "command": "node guard.js" } ] } 2. 内联(挂载 config,追加在文件 hooks 之后): yaml - id: hooks name: dsh-plugin-hooks config: configFile: C:/path/to/hooks.json # 可选 hooks: - id: always-deny-db event: pre-tool tools: [bash] command: "node deny-db.js" 字段:id(必填、唯一)、event(pre-tool | post-tool)、tools(可选,默认全部)、command(必填)、timeoutMs(可选)、enabled(默认 true)。 ## 安装 bash dsh plugin --profile web add dsh-plugin-hooks 挂载: yaml - insert: - id: hooks name: dsh-plugin-hooks ## Hook 命令收到的数据 命令通过 stdin 收到一行 JSON payload: json { "event": "PostToolUse", "hookId": "lint-after-edit", "toolName": "edit", "args": { "path": "a.js" }, "sessionId": "s_xxx", "cwd": "C:/repo", "result": { "isError": false, "exitCode": 0, "error": null }, "durationMs": 123 } 环境变量:CLAUDE_PROJECT_DIR(会话 cwd)、DSH_HOOK_EVENT、DSH_HOOK_ID、DSH_SESSION_ID。pre-tool payload 无 result/durationMs 字段。 ## 命令 - /hooks — 列出已配置 hooks + 最近 20 次运行记录(含退出码/错误摘要) - /hooks-reload — 重新读配置文件,热加载,无需重启 ## 设计说明 - 通过 ctx.on("tools/pre-execute"|"tools/post-execute") 接入 Cordis waterfall;pre-tool 非零退出时返回 { kind:"deny", reason } 阻断调用(与 dsh-tools 的 deny 决策契约一致,见 prepareExecution)。 - 钩子命令经 ctx.shell.run 执行(自动套用沙箱策略与超时),payload 走 stdin、cwd 走 env —— 与 DSH 为 hooks bridges 预留的 shell 词汇表一致。 - 配置解析/匹配/payload 构建全部在 lib/config.js 纯函数里,npm test 零依赖。 - hook 运行不会递归触发工具事件(shell 是服务调用,不是工具调用)。 ## 诚实边界 - hook 命令是受信任的 host 配置(等同 Claude Code hooks):能读写任何 host 能访问的东西,只在可信 profile 启用。 - pre-tool 命令会阻塞工具执行(超时/退出码决定放行与否);post-tool 命令失败只记录,不影响结果。 - v1 只支持工具生命周期事件;Stop / SessionEnd 类 hook 需要会话事件订阅,官方尚未暴露,留待后续。 - 若 ctx.shell 未挂载,插件照常加载但 hook 不会运行(启动时在 /hooks 里提示)。 ## 本地开发 bash cd plugins/dsh-plugin-hooks npm test # node --test,零依赖 接线集成测试(真实 Cordis + mock shell,验证 allow/deny 语义与 payload):见仓库根 test-wiring.mjs。Not by stars — picked by hand, one at a time.
A visual settings dashboard for DeepSeek Harness: every registered settings namespace — including third-party plugin ones the official UI never covers — rendered as editable, schema-driven forms. Early, but the right direction: stop hand-editing YAML.
A DIY trajectory visualizer for DeepSeek Harness: watch the agent’s plan and execution unfold as a graph instead of scrolling raw logs. Early, but it fills a real gap — understanding at a glance what the agent is doing.
Dispatch DSH work from Claude Code / Codex: spin up in-host DSH agent sessions with per-tier presets, watch native subagent progress, and borrow a multimodal bridge that lends the text-only harness vision and image generation. An orchestration plugin that turns DSH into a backend for other coding agents.
