dsh-apple-mode English · 简体中文 Xcode AI integration mode for DeepSeek Harness (dsh) — an agent preset + installer that gives your DSH sessions the full Xcode AI stack: - 26 Xcode MCP tools (mcp__xcode__*) via Apple's official mcpbridge - Xcode Intelligence–style persona (Swift-first, tool-assisted, explain-vs-change classification) adapted from the IDEIntelligenceChat prompt templates - 10 Apple platform skills (SwiftUI, App Intents, security hardening, bounds safety, …) generated locally from your own Xcode > 📌 dsh-plugin topic repo. DeepSeek Harness is in developer preview — pin an exact dsh version for your automation. ## Why a preset (mode) instead of a global MCP wiring? The three capabilities map onto three different DSH mechanisms: | Layer | Capability | DSH mechanism | |---|---|---| | Execute | 26 mcp__xcode__* tools | dsh-mcp-client (mounted inside the preset) | | Knowledge | 10 Apple skills | dsh-skill-filesystem (global, lazy-loaded) | | Behavior | Xcode Intelligence persona | agent preset (this repo) | Wiring the MCP server globally would put ~26 large tool schemas (~6k+ tokens/request) into every session. Mounting it inside a preset keeps the cost only in sessions that opt in — pick Apple Mode when creating a session, and you get the whole stack; other sessions stay lean. ## Requirements - macOS - DeepSeek Harness: npx @deepseek-ai/dsh web - Xcode 26+ (contains mcpbridge and xcrun agent skills export). To use the MCP tools, Xcode must be running with the target project open, and you must click Allow on the MCP access dialog Xcode shows (see Usage). ## Install sh git clone https://github.com/jihongboo/dsh-apple-mode.git cd dsh-apple-mode ./install.sh install.sh does three things: 1. Detects your Xcode installs and lets you choose which one provides mcpbridge (see below). 2. Installs the apple agent preset → ~/.dsh/.agent-presets/apple/ (existing copy is backed up). 3. Generates the 10 Xcode AI skills on your machine via xcrun agent skills export and merges them into ~/.agents/skills/ (the DSH skill root, hot-reloaded by the filesystem watcher). > Why no vendored skills? The skills are Apple-authored guidance. Generating them from your own Xcode at install time avoids redistributing Apple content — the repo ships only our own code, config, and docs. ### Choosing an Xcode (multiple installs) If you have several Xcode versions (e.g. Xcode.app, Xcode-beta.app, Xcode-26.2.app), mcpbridge lives in each one's Contents/Developer/usr/bin — and only in Xcode 26+. install.sh scans /Applications for every install that provides it and prompts you to pick: text Found Xcode installs providing mcpbridge: 1) /Applications/Xcode-beta.app/Contents/Developer (xcode-select default) 2) /Applications/Xcode.app/Contents/Developer Choose (1-2, default 1): - Default = the Xcode selected by xcode-select → the preset uses command: xcrun mcpbridge (portable; follows future xcode-select changes). - Pick another → the chosen …/Contents/Developer/usr/bin/mcpbridge is baked into the installed preset as an absolute path. - Non-interactive: ./install.sh --xcode /Applications/Xcode.app (or --xcode …/Contents/Developer); ./install.sh --list-xcodes prints the candidates. - Switch at runtime without reinstalling: ./install.sh --runtime-selectable installs bin/mcpbridge as the command; set DSH_XCODE_DEVELOPER_DIR=/Applications/…/Contents/Developer when launching dsh to switch. (Resolution: DSH_XCODE_DEVELOPER_DIR → xcrun → newest /Applications/Xcode*.app.) - Drive a specific running Xcode instance: add env: { MCP_XCODE_PID: '<pid>' } to the mcp-xcode row of the installed preset. To change the choice later: re-run ./install.sh, edit the mcp-xcode row in ~/.dsh/.agent-presets/apple/agent.cordis.yml, or use the runtime env var above. ### Alternative: global bundle (MCP in every session) sh dsh plugin --profile web add "github:jihongboo/dsh-apple-mode" Installs the cordis.patch.yml bundle, which wires the Xcode MCP server into every session of the profile — no preset selection needed, at the cost of the tool-schema tokens in all sessions. Use one install path, not both: each registers serverName: xcode, and a duplicate server name fails the later instance at load. See docs/global-mcp.md. ## Usage 1. Restart dsh (or just open a new session — the preset can only be selected on a blank session). 2. Pick Apple Mode as the agent preset when creating the session. 3. The session now has: - mcp__xcode__* tools — operate the open Xcode workspace: XcodeRead/Write/Update/MV/RM, XcodeGlob/Grep/LS, UpdateTargetBuildSetting/UpdateFileCompilerFlags, XcodeListNavigatorIssues, scheme/run-destination/test-plan switching, XcodeNewTarget, StringCatalogRead/Edit, … - All Apple platform skills (lazy-loaded on demand). - An Apple-first, tool-assisted working style. > Before using the mcp__xcode__* tools: > 1. Xcode must be running with the project/workspace you want to work on opened in it. > 2. On first connection, Xcode shows an MCP access dialog — click Allow (允许). Until you do, tool calls will be rejected. Build/run/test still happen from the terminal (xcodebuild, pipe through xcsift for structured output); the MCP toolset covers project surgery, build settings, diagnostics, destinations, and localization. ## What you get ### MCP tools (26, namespaced mcp__xcode__*) | Group | Tools | |---|---| | Project I/O | XcodeRead XcodeWrite XcodeUpdate XcodeMV XcodeRM XcodeMakeDir | | Search | XcodeGlob XcodeGrep XcodeLS | | Targets & settings | XcodeNewTarget XcodeListTemplates XcodeListTargets UpdateTargetBuildSetting UpdateFileCompilerFlags | | Scheme / destination / tests | XcodeListSchemes XcodeSwitchScheme XcodeListRunDestinations XcodeSwitchRunDestination XcodeListTestPlans XcodeSwitchTestPlan | | Diagnostics | XcodeListNavigatorIssues XcodeRefreshCodeIssuesInFile | | Localization | StringCatalogRead StringCatalogEdit | | Windows | XcodeListWindows XcodeGetCurrentFile | ### Skills (10, generated at install time) swiftui-specialist · swiftui-whats-new-27 · app-intents-specialist · app-intents-whats-new-27 · audit-xcode-security-settings · adopt-c-bounds-safety · uikit-app-modernization · modernize-tests · device-interaction · building-document-based-swiftui-applications ## Repository layout text . ├── presets/apple/ # The agent preset: agent.cordis.yml + preset.yml ├── bin/mcpbridge # Runtime-selectable mcpbridge launcher (--runtime-selectable) ├── cordis.patch.yml # Global-MCP bundle patch (dsh plugin add) ├── package.json # Bundle manifest (dsh.bundle.patch) ├── docs/ │ ├── XCODE_AI_INTEGRATION.md # Full integration notes (Chinese) │ └── global-mcp.md # Alternative: wire the MCP server into every session ├── install.sh # Xcode picker + preset install + local skills generation ├── uninstall.sh └── LICENSE # MIT ## Customization - Different Xcode: re-run ./install.sh (picker), ./install.sh --xcode <path> (non-interactive), --runtime-selectable + DSH_XCODE_DEVELOPER_DIR, or add env: { MCP_XCODE_PID: '<pid>' } to the mcp-xcode row to drive a specific running instance. See Choosing an Xcode. - Persona: edit the persona row text in the same file. - Sync skills after Xcode updates: re-run ./install.sh (skills are replaced, preset is backed up). - Keep in sync with upstream standard preset: diff against node_modules/@deepseek-ai/dsh/config/agent-presets/standard/agent.cordis.yml. ## Security notes - MCP tool calls do not go through the DSH file sandbox — they go through the tool-approval flow. XcodeUpdate/XcodeWrite modify real Xcode project files (including project.pbxproj). - The preset only activates when you select it; no global config is touched by install.sh. ## Contributing PRs welcome.
