+The [shared-base Web fetch default](2026-09-01-shared-base-web-fetch-default.md) supersedes this record's fetch opt-in decision. This record remains authoritative for the default search provider, credential resolution, endpoint, timeout, and the separation between provider availability and model-tool registration.

 ## Problem
 
 The harness had a complete Web capability family—provider registry, DeepSeek/Exa/Perplexity search providers, local fetch, stable model tools, and structured result presentation—but the shipped `dsh web` composition mounted none of it. The model could not discover current information unless a deployment supplied a custom overlay. Merely mounting the existing DeepSeek provider would not complete the WebUI path: the Models page stores `DEEPSEEK_API_KEY` through `ctx.credentials`, while the search provider froze only the process environment at plugin load, so a key entered or rotated in the running UI would not reach search.
 
 ## Decision
 
-`apps/cli/config/base.cordis.yml` explicitly mounts `dsh-web` with `searchProvider: deepseek-official` and `fetchProvider: http`, `dsh-web-search-deepseek`, `dsh-web-fetch-http`, and `dsh-tool-web` with `fetch: false` and `searchTimeoutMs: 60000`. The shared base therefore keeps only `web_search` visible unless a product preset enables fetch; the shipped Web `cordis`, `code`, and `standard` presets do so. Explicit provider ids keep selection independent of registration order and leave personal or `--config` overlays able to replace or disable the rows. The one-minute shipped budget covers an auxiliary DeepSeek Messages request plus server-side retrieval while leaving `dsh-tool-web`'s provider-neutral 30-second default unchanged for custom compositions. The [Web capability seam decision](../architecture/2026-06-24-web-capability-seam.md) owns the public-fetch security policy and Web preset default.
+`packages/bundle/base/cordis.patch.yml` explicitly mounts `dsh-web` with `searchProvider: deepseek-official` and `fetchProvider: http`, `dsh-web-search-deepseek`, `dsh-web-fetch-http`, and `dsh-tool-web` with `searchTimeoutMs: 60000`. The [shared-base Web fetch default](2026-09-01-shared-base-web-fetch-default.md) owns the current `fetch: true`; this record continues to own provider selection, search credentials, and timeout.

The [Web capability seam decision](../architecture/2026-06-24-web-capability-seam.md) owns the public-fetch security policy.
 
 DeepSeek search uses the same `DEEPSEEK_API_KEY` credential reference as the official conversation adapter. The provider resolves that reference inside every search through the optional `ctx.credentials` service; only a composition without the seam falls back to the launching process environment, and a non-empty literal `apiKey` remains the programmatic last resort. A stored or rotated Web Models key therefore reaches the next search without restarting or retaining the value on the provider. Because `WebSearchProvider.available()` is synchronous, it treats an installed resolver as locally usable and missing dynamic credentials fail the operation with the provider-specific `WEB_PROVIDER_CREDENTIAL_MISSING` code while the stable tool schema stays registered.

 ## 问题
 
 该 harness 已具备完整的 Web 能力体系：提供方注册表、DeepSeek、Exa 和 Perplexity 搜索提供方、本地抓取、稳定的面向模型工具，以及结构化结果呈现，但已交付的 `dsh web` 组合没有挂载其中任何一项。除非部署提供自定义覆盖层，否则模型无法发现最新信息。仅挂载现有 DeepSeek 提供方仍无法打通 WebUI 链路：Models 页面通过 `ctx.credentials` 存储 `DEEPSEEK_API_KEY`，而搜索提供方只会在插件加载时固定读取进程环境，因此在运行中的 UI 输入或轮换的密钥无法用于搜索。
 
 ## 决策

 DeepSeek 搜索使用与官方会话适配器相同的 `DEEPSEEK_API_KEY` 凭据引用。提供方在每次搜索内部通过可选的 `ctx.credentials` 服务解析该引用；只有未挂载该 seam 的组合才会回退到启动进程的环境变量，非空的 `apiKey` 字面值仍作为程序化配置的最后兜底。因此，由 Web 的 Models 页存储或轮换的密钥无需重启即可用于下一次搜索，提供方也无需保留该值。由于 `WebSearchProvider.available()` 是同步方法，它会将已安装解析器视为本地可用；若动态凭据缺失，操作会以提供方专属错误码 `WEB_PROVIDER_CREDENTIAL_MISSING` 失败，而稳定的工具 schema 仍保持注册。

+# Agent Note: Shared-base Web fetch default
+
+Status: implemented

+English | [中文](2026-09-01-shared-base-web-fetch-default.zh.md)
+
+This decision partially supersedes the fetch opt-in choice in [Default Web search in shipped compositions](2026-07-31-web-default-search.md). That record continues to own search provider selection, credentials, endpoint, timeout, and the separation between provider availability and model-tool registration; no active Agent Note is fully superseded or eligible for archival.
+
+## Problem
+
+Every shipped full agent product accepts anonymous public Web fetch, but `dsh-base` disabled `web_fetch` and required each application bundle to repeat the same override. The repeated configuration omitted ACP, made new base-backed profiles search-only unless their authors noticed the exception, and forced otherwise identical snapshot headers to split by product.
+
+## Decision
+
+`packages/bundle/base/cordis.patch.yml` mounts `dsh-tool-web` with `fetch: true` and the shipped 60-second search timeout. Headless, full SDK, ACP, and custom base-only profiles inherit both `web_search` and `web_fetch` without application-level overrides. The Web app disables the base tool row and composes the same pair per agent preset. The standalone `sdk-minimal` profile remains independent of base.
+
+The base HTTP provider permits anonymous `http:` and `https:` requests only to validated public destinations. Fetch executes outside shell and filesystem sandbox or approval presets and requires no per-call approval; public-destination validation does not prevent public data egress. A product that requires a different network policy overrides the complete `tool-web` config in a later bundle or profile patch.
+
+## Alternatives considered
+
+**Keep fetch disabled in base and enable it in each product.** Rejected because every shipped full product selects the same capability, so the repeated rows encode no product difference and can omit future base-backed profiles.
+
+**Add only an ACP override.** Rejected because it repairs the current omission while retaining three redundant application-level settings and the same failure mode for future profiles.
+
+## Consequences
+
+Base-backed model requests expose the fetch schema and prompt guidance by default, including ACP automation and custom profiles that name only `dsh-base`. Restricted deployments must opt out explicitly. Headless, SDK, and ACP can share the same model-header snapshot sources, while focused real-profile tests pin the shipped tool roster.

+本决策部分取代[已交付组合中的默认 Web 搜索](2026-07-31-web-default-search.zh.md)里关于抓取按需启用的选择。该记录继续负责搜索提供方选择、凭据、端点、超时，以及提供方可用性与模型工具注册之间的区分；没有任何 active Agent Note 被完全取代或符合归档条件。
+
+## 问题
+
+所有随附的完整 agent 产品都接受匿名公开 Web 抓取，但 `dsh-base` 会禁用 `web_fetch`，要求每个应用组合包重复相同的覆盖。重复配置遗漏了 ACP，使新的 base-backed profile 默认只有搜索能力，除非作者注意到这个例外，还迫使产品之间原本相同的 snapshot header 分开维护。
+
+## 决策
+
+`packages/bundle/base/cordis.patch.yml` 以 `fetch: true` 和随附的 60 秒搜索超时挂载 `dsh-tool-web`。Headless、完整 SDK、ACP 与仅使用 base 的自定义 profile 会继承 `web_search` 和 `web_fetch`，无需应用级覆盖。Web app 会禁用 base 工具配置项，并按 agent preset 组合相同的一对工具。独立的 `sdk-minimal` profile 不使用 base，因此保持不变。
+
+base HTTP 提供方只允许匿名请求经过验证的公开 `http:` 与 `https:` 目的地址。抓取在 shell 和文件系统 sandbox 或审批 preset 之外执行，无需逐次审批；公开目的地址校验不会阻止向公网发送数据。需要不同网络策略的产品应在后续组合包或 profile patch 中覆盖完整的 `tool-web` 配置。
+
+## 考虑过的替代方案
+
+**在 base 中禁用抓取，再由每个产品分别启用。** 不予采纳：所有随附的完整产品都选择相同能力，重复配置没有表达产品差异，还可能遗漏未来的 base-backed profile。
+
+**只增加 ACP 覆盖。** 不予采纳：这种方式能修复当前遗漏，但会保留三处重复的应用级设置，也会让未来 profile 面临相同问题。
+
+## 后果
+
+基于 base 的模型请求默认暴露抓取 schema 与 prompt 指引，包括 ACP 自动化和只列出 `dsh-base` 的自定义 profile。受限部署必须显式关闭。Headless、SDK 与 ACP 可以共享相同的模型 header snapshot 来源，聚焦的真实 profile 测试会固定随附工具集合。

-The base bundle mounts the native DeepSeek adapter, settings and credential providers, stable `web_search`, the public-only HTTP fetch provider, and feedback-gated session telemetry. Provider credentials resolve from the inherited environment, `$DSH_HOME/.credentials.yaml`, the invoking directory's `.env`, then `$DSH_HOME/.env`; the managed document is never materialized into `process.env`, while both `.env` files are ordinary launch environment layers. Search uses `DEEPSEEK_API_KEY` and accepts `DEEPSEEK_SEARCH_BASE_URL`. The Web app's `cordis`, `ptc`, and `standard` agent presets expose `web_fetch` in every sandbox and approval mode without per-call confirmation; the provider still rejects non-public destinations before connecting.

 Session telemetry defaults to feedback-gated sharing: nothing is uploaded until the user records `/feedback`, and each recorded feedback uploads the session records not yet shared, through that event; a resumed session shares only its current lifecycle. `DSH_TELEMETRY_MODE=FULL` instead streams every projected session event as OTLP/HTTP logs, `DSH_TELEMETRY_MODE=DISABLED` keeps everything local, and any non-empty `DSH_TELEMETRY_DISABLED` remains an authoritative hard opt-out. `DSH_TELEMETRY_OTLP_URL` selects another collector. The shipped base has no telemetry redaction rule, so released exports can contain message text, tool arguments and results, and workspace paths; the [feedback-gated-default Agent Note](../../../.agents/notes/implemented/feature/2026-08-25-feedback-gated-telemetry-default.md) owns that deployment decision.

-Out of the box, every profile built on this core provides: a DeepSeek model connection (the provider and model are configurable, and you can enable extra providers from your settings), the full tool set — file editing, shell commands, web search, subagents, task and goal tracking — durable sessions that survive restarts, and the default permission policy that confines file writes to your workspace and asks before risky actions.

Call get_goal before update_goal and copy its exact goal_id and revision.

 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.

 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
