dsh-app-native

A mobile native development agent preset for DeepSeek Harness (dsh): one preset covering iOS, Android and HarmonyOS in all of their native languages, with the platform detected from the workspace.

Installing it lands the preset in $DSH_HOME/.agent-presets/app-native/, so it is selectable in the preset picker of every profile.

Install

dsh plugin --profile web add dsh-app-native

Restart that profile, then pick 移动端原生开发 in the preset picker of a new session.

No manual copying: the bundle's single host row installs the packaged preset/app-native/ into $DSH_HOME/.agent-presets/app-native/ idempotently.

What the preset does

Instead of a generic coding agent, you get one that identifies the platform first and then works by that platform's rules:

Platform	Languages	Discipline baked into the persona
iOS	Objective-C, Swift, C/C++	Do not switch languages (no ObjC→Swift ports), no new pods/packages for a bug fix; get real compiler answers from the lsp_* tools (clangd for .m/.mm/.h/.c/.cpp, sourcekit-lsp for .swift); build with ios_sim_build_run and read the xcodebuild error tail; never hand-edit .xcodeproj/.pbxproj; drive UI through ios_sim_* and confirm every action with expect_text / expect_gone
Android	Kotlin, Java, C/C++ (NDK)	Kotlin-first in new code but match the module you are in (no incidental Java→Kotlin rewrites, no View→Compose migration as a side effect); build with the project's own ./gradlew and read Gradle failures; dependencies live in build.gradle(.kts) / version catalogs, not dropped-in jars; never hand-edit generated files (merged manifest, BuildConfig, R, build/, the wrapper); runtime evidence comes from the device loop (adb install / am start + logcat)
HarmonyOS	ArkTS, C/C++ (Native API), legacy JS/FA	Take platform APIs from official, version-classified sources (hms_api / hms_docs / hms_api_change / hms_knowledge) and state the target version; prefer ArkTS in new code; arkts_check → build_project as the verify loop; hdc_log for device logs; the hdc-bridge observe → locate → act → verify device loop; never hand-edit hvigor/ohpm output

Shared rules: conservative production changes (no new dependency, permission, entitlement or build configuration without asking), never touch vendored or generated code (Pods/, oh_modules/, .gradle/, build/, *.pbxproj), and — because the active model may be text-only — send device and UI screenshots to modlens_read_image for structured evidence rather than read_image.

Workspace markers the preset dispatches on:

oh-package.json5 + hvigorfile.ts + *.ets                              -> HarmonyOS
*.xcodeproj | *.xcworkspace + Podfile | Package.swift + *.m/*.swift   -> iOS
settings.gradle(.kts) | build.gradle(.kts) + AndroidManifest.xml + *.kt/*.java -> Android

The tool set is identical to the shipped standard preset (files, shell, search, web, skills, plan, goals, subagents, workflows). Only the persona differs — the preset changes who the agent is and how it works, never how much it can do.

Companion plugins (optional)

The capabilities the persona names come from other plugins / host rows, not from this package. Without them the preset still runs — those specific tools are just absent:

For	Install
lsp_* code intelligence (clangd / sourcekit-lsp / tsc)	dsh-lsp-actions, with a servers table in the profile's cordis.patch.yml
iOS simulator/device loop (ios_sim_*, ios_real_start_wda)	@zseven-w/dsh-ios (macOS + full Xcode)
HarmonyOS device loop (hdc_*) and HarmonyOS NEXT skills	dsh-hdc-bridge, github:linhay/harmony-next.skills
Vision for a text-only model (screenshot evidence)	@liustack/modlens
arkts_check / build_project / hms_*	provided by the deployment's DevEco / deveco-cli toolchain

Update and removal

• Update: dsh plugin --profile web update dsh-app-native, then restart. Note the installer never overwrites an existing $DSH_HOME/.agent-presets/app-native/ that already holds an agent.cordis.yml, so your local edits survive. To take the packaged version instead, delete that directory and restart.
• Remove: dsh plugin --profile web remove dsh-app-native. The preset files are not deleted for you — they live in your own home directory. Delete $DSH_HOME/.agent-presets/app-native/ when you no longer want them.
• Switching: a preset can only be chosen on a new session, or one that has produced nothing yet (no messages, no tool calls); a running session keeps the composition it started with.
• Rename or disable: set presetId or installPreset: false on the host row's config.

Consistency

The preset composition is byte-identical to the shipped standard preset except for the persona block, and it passes agentPresets.standingKeyFor() mount validation (the same mount a session start performs). The preset/app-native/ directory in this package is exactly what gets installed.
