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.
