DSH Mobile — DeepSeek Harness Remote

An open-source Android companion that puts your DeepSeek Harness in your pocket.
Drive sessions, review plans and goals, answer approvals and questions, and get notified when the harness finishes — from your phone, over your local network.

DSH Mobile is an unofficial companion app for the
DeepSeek Harness (MIT), mirroring its web GUI
feature-for-feature in the harness's own visual language. Android only, Kotlin + Jetpack Compose.

Screenshots

Connect	Chat	Trajectory
Recent harnesses with live reachability, LAN discovery, manual host:port, auto-connect.	Streamed turns, a glyph per tool, expandable tool cards, permission picker.	The same session as a per-turn ledger with usage totals.

Session details	Subagents
Context breakdown, goal, plan mode, background jobs, queued turns, host info, session-log export.	The subagent catalog — open a child's transcript, follow up, or interrupt it.

Features

• Connect effortlessly — auto-discovers a harness on your Wi-Fi (active subnet scan +
  readiness handshake), remembers hosts and probes them for liveness on the way in, supports
  manual host:port entry, loopback for same-device setups, and auto-connect toggles
  (last used / LAN / same device).
• Discord-style navigation — swipe right from the left edge to open the workspace-grouped
  chat list, swipe left to close it, swipe left from the right edge for the session details panel.
• Full chat experience — streamed turns with reasoning disclosure, markdown,
  terminal/diff/read/search/web tool cards, queue dock (edit / remove / steer), history paging,
  image attachments.
• Slash commands and skills — the composer adjudicates a / line against the session's own
  command catalog and runs it through the harness's command gateway; anything the catalog does not
  claim is sent as a prompt, which is how skills are invoked.
• Everything the GUI does — goals (phases, rounds, pause/resume/edit), plan mode + plan review,
  permission approvals, user questions, todo dock, subagents (catalog, follow-ups, interrupt),
  background jobs, workflow runs, skills, model selection, agent presets, session search,
  trajectory ledger, session export, message feedback.
• Notifications — turn complete, goal complete / blocked, review or question waiting for you;
  background connection via a foreground service.
• Looks like the harness — the exact DeepSeek Harness design tokens (colors, type, radii,
  disclosure rows, shimmer, ink buttons) with light / dark / system themes.
• 11 languages — English, 中文, हिन्दी, Español, Français, العربية, বাংলা, Português, Русский,
  اردو, ไทย (RTL aware).

Requirements

• Android 8.0+ (minSdk 26).
• A running DeepSeek Harness
  (tested against 0.1.0-rc.7).

Quick start

1. Install the latest APK from
   Releases.
2. On your computer, make the harness reachable from your phone:
   • USB / emulator: dsh web, then adb reverse tcp:3080 tcp:3080 — in the app connect to
     127.0.0.1:3080.
   • Wi-Fi: apply the one-file LAN patch described in
     harness/README.md, restart dsh web, then tap Scan network
     in the app.
3. Pick a session, chat, and get notified when the harness is done.

If a connect attempt fails, the app names the cause; the wiki's
Troubleshooting page is
keyed on that exact sentence.

Compatibility & security

• See docs/COMPATIBILITY.md for the harness version matrix and
  loopback-only surfaces.
• Read docs/SECURITY.md first — the harness has no authentication; only
  use LAN mode on trusted networks. The app says so on the connect screen for the same reason.

Building

./gradlew :app:assembleDebug      # debug APK
./gradlew :app:assembleRelease    # release APK (signed when keystore env is set)

The shipped version comes from the git tag: the release workflow exports DSH_VERSION_NAME from
the tag name, and versionCode is derived from it. A local build falls back to the literal in
app/build.gradle.kts.

See CONTRIBUTING.md for the development loop against a real harness, the module
layout, and the release workflow.
