+# Agent Note: SDK default file editor selection
+
+Status: implemented
+
+English | [中文](2026-09-05-sdk-default-file-editor.zh.md)
+
+## Problem
+
+The standard SDK profile inherits both `read`/`write`/`edit` and `str_replace_editor` from the shared base. These offer overlapping file editing interfaces, while the Web standard preset selects the former. [Issue #3599](https://github.com/deepseek-harness/deepseek-harness/issues/3599) requests the same editor choice for the standard SDK without making all SDK and Web behavior identical.
+
+## Decision
+
+The [SDK application patch](../../../../packages/bundle/sdk-app/cordis.patch.yml) disables the inherited `tool-str-replace-editor` row. The SDK retains `read`, `write`, and `edit`; the shared base, reusable editor package, and standalone `sdk-minimal` composition retain their own defaults. A trusted profile, home, or invocation patch can explicitly enable the row.
+
+This narrows the SDK tool default described by [one dsh launcher](../architecture/2026-08-22-single-dsh-application-launcher.md). That decision remains active for launch ownership, shared services, and patch precedence; no active note is fully superseded.
+
+## Alternatives considered
+
+**Keep both editors enabled.** Shared base composition explains their availability, but the standard SDK does not need two default interfaces for the same file editing operations. Callers requiring this editor can select it explicitly.
+
+**Remove the shared registration or reuse the entire Web preset.** Either changes more than the requested SDK default. Keeping the change in the SDK bundle preserves other profiles and the existing application architecture.
+
+## Consequences
+
+Default SDK requests omit the editor schema. Callers that select `str_replace_editor` by name need an explicit patch or their existing dedicated composition. This decision makes no claim of complete SDK/Web tool parity.
+
+## Verification
+
+The [SDK profile process test](../../../../apps/cli/tests/profiles/sdk/keyless-smoke.e2e.ts) captures actual model requests for the default roster, explicit editor enablement, and standalone minimal roster. [SDK recorded sessions](../../../../snapshots/sdk/sdk.snapshot.ts) pin the resulting schemas; shared cross-profile and persistent-editor recordings explicitly retain their required editor.

+# Agent Note: SDK 默认文件编辑器选择
+
+Status: implemented
+
+[English](2026-09-05-sdk-default-file-editor.md) | 中文
+
+## Problem
+
+标准 SDK profile 从共享 base 同时继承 `read`/`write`/`edit` 和 `str_replace_editor`。这些工具提供重叠的文件编辑接口，而 Web standard preset 选择前者。[Issue #3599](https://github.com/deepseek-harness/deepseek-harness/issues/3599) 要求标准 SDK 采用相同的编辑器选择，不要求 SDK 与 Web 的全部行为一致。
+
+## Decision
+
+[SDK 应用 patch](../../../../packages/bundle/sdk-app/cordis.patch.yml) 禁用继承的 `tool-str-replace-editor` 配置项。SDK 保留 `read`、`write` 和 `edit`；共享 base、可复用编辑器包及独立 `sdk-minimal` 组合保留各自的默认值。受信任的 profile、home 或逐次调用 patch 可以显式启用该配置项。
+
+本决策收窄了[统一 dsh 启动器](../architecture/2026-08-22-single-dsh-application-launcher.zh.md)所述的 SDK 工具默认值。该决策对启动所有权、共享服务和 patch 优先级仍然有效；没有被完全取代的活跃 Agent Note。
+
+## Alternatives considered
+
+**继续默认启用两个编辑器。** 共享 base 组合解释了它们为何可用，但标准 SDK 无需为相同的文件编辑操作默认提供两套接口。需要此编辑器的调用方可以显式选择它。
+
+**移除共享注册或复用整个 Web preset。** 两者都会扩大 SDK 默认值调整的范围。将改动放在 SDK bundle 中可以保留其他 profile 和现有应用架构。
+
+## Consequences
+
+默认 SDK 请求省略该编辑器 schema。按名称选择 `str_replace_editor` 的调用方需要显式 patch 或其现有专用组合。本决策不承诺 SDK/Web 的全部工具一致。
+
+## Verification
+
+[SDK profile 进程测试](../../../../apps/cli/tests/profiles/sdk/keyless-smoke.e2e.ts) 捕获默认工具清单、显式启用编辑器和独立极简工具清单的实际模型请求。[SDK 录制会话](../../../../snapshots/sdk/sdk.snapshot.ts) 固定最终 schema；跨 profile 共享录制与持久编辑器录制显式保留其所需的编辑器。
