Reference / 参考手册

Environment Variables / 环境变量

Variable Purpose / 用途
DWS_CONFIG_DIR Override default config directory / 覆盖默认配置目录
DWS_SERVERS_URL Point discovery at a custom server registry endpoint / 将服务发现指向自定义端点
DWS_CLIENT_ID OAuth client ID (DingTalk AppKey)
DWS_CLIENT_SECRET OAuth client secret (DingTalk AppSecret)
DWS_TRUSTED_DOMAINS Comma-separated trusted domains for bearer token (default: *.dingtalk.com). * for dev only / Bearer token 允许发送的域名白名单,默认 *.dingtalk.com,仅开发环境可设为 *
DWS_ALLOW_HTTP_ENDPOINTS Set 1 to allow HTTP for loopback during dev / 设为 1 允许回环地址 HTTP,仅用于开发调试
DWS_DISABLE_KEYCHAIN macOS only. Set 1 to skip system Keychain for the encryption key and use file-based storage (same scheme as Linux). For sandboxed runtimes (e.g. Codex App) that block Keychain APIs. Weakens at-rest protection — DEK and ciphertext live in the same directory. / 仅 macOS。设为 1 时跳过系统 Keychain,密钥以文件形式存储(与 Linux 一致)。用于 Keychain API 被拦截的沙盒环境(如 Codex App)。代价是 DEK 与密文同目录,保护强度低于默认方案

Exit Codes / 退出码

Code Category Description / 描述
0 Success Command completed successfully / 命令执行成功
1 API MCP tool call or upstream API failure / MCP 工具调用或上游 API 失败
2 Auth Authentication or authorization failure / 身份认证或授权失败
3 Validation Invalid input, flags, or parameter schema mismatch / 输入参数校验失败
4 PAT PAT authorization interception; stderr carries raw machine-readable PAT JSON / PAT 授权拦截;stderr 返回原始机器可解析 JSON
5 Internal Unexpected internal error / 未预期的内部错误
6 Discovery Server discovery, cache, or protocol negotiation failure / 服务发现、缓存或协议协商失败

With -f json, error responses include structured payloads: category, reason, hint, actions.

使用 -f json 时,错误响应包含结构化字段:categoryreasonhintactions

Output Formats / 输出格式

dws contact user search --query "Alice" -f table   # Table (default, human-friendly / 表格,默认)
dws contact user search --query "Alice" -f json    # JSON (for agents and piping / 适合 agent)
dws contact user search --query "Alice" -f raw     # Raw API response / 原始响应
dws schema -f pretty ding.send_ding_message          # Pretty (ANSI-colored, schema-aware / 彩色分区,专为 schema 设计)

Dry Run / 试运行

dws todo task list --dry-run    # Preview MCP call without executing / 预览但不执行

Output to File / 输出到文件

dws contact user search --query "Alice" -o result.json

Schema Introspection / Schema 查询

dws schema 查询已发现的 MCP 产品和工具元数据。不带参数列出所有产品,带路径输出单个工具的完整 schema。

路径写法

dws schema                                  # 列出所有产品 + 工具名
dws schema ding.send_ding_message           # canonical: product.rpc_name
dws schema ding.message.send                # CLI 点路径: product.group.cli_name
dws schema "ding message send"              # CLI 空格路径(同上)
dws schema --cli-path "ding message send"   # 显式 flag(脚本友好,免转义)
dws schema -f pretty ding.send_ding_message # ANSI 着色分区展示(人肉查看最舒服)

Canonical 路径先匹配;落空后走 CLI 路径(product → group.. → cli_name)。

单工具输出字段

字段 说明
name / cli_name / canonical_path MCP RPC 名 / CLI 叶子名 / product.rpc_name
group CLI 父级 group 路径(dot-separated)
title / description 工具名/说明(overlay 优先)
parameters / required MCP 输入 JSON Schema 的 properties / required
output_schema MCP 输出 Schema(上游下发时才有)
sensitive 敏感写操作,需 --yes 确认
auth DingTalk 授权元数据,包括 requiredScopes / requiredPermissions / recommendedScopes / grantProductCodes / riskAction / confirmationRequired
annotations.destructive_hint 对齐 MCP 2025+ annotations,目前从 sensitive 映射
flag_overlay[param] CLI 层对 MCP 参数的改写:alias / transform / transform_args / env_default / default / hidden

调试 --flag 行为的第一站flag_overlay —— 比如 --users 0232... 能不能直接用,看 receiverUserIdList.transform == "csv_to_array" 即可判断。

筛选输出

dws schema ding.send_ding_message --jq '.tool.flag_overlay'       # 只看 overlay
dws schema calendar.create_event --jq '.tool.auth'                # 只看授权元数据
dws schema --jq '.products[] | {id, count: (.tools|length)}'      # 各产品工具数
dws schema aitable.delete_base --jq '.tool.annotations'           # 敏感操作提示

Shell Completion / 自动补全

# Bash
dws completion bash > /etc/bash_completion.d/dws

# Zsh
dws completion zsh > "${fpath[1]}/_dws"

# Fish
dws completion fish > ~/.config/fish/completions/dws.fish
