dsh-win-minimal

A real minimal mode for DeepSeek Harness on Windows.

One-line persona · zero runtime context · three tools · compaction included · shortest fixed prefix

What it is

An agent preset. After installation, new sessions offer a「Minimal (Windows)」choice whose entire system prompt is:

You are a helpful software engineer assistant.

Three tools only:

Why

The shipped minimal preset relies on a persistent bash PTY whose readiness detection needs PTY process inspection — unsupported on win32. DSH Desktop therefore hides minimal on Windows entirely.

This preset is its Windows equivalent: same fixed persona + complete mode, same no-runtime-context, the standard compaction chain (auto + /compact) added back, same str_replace_editor — with the persistent bash swapped for one-shot gitbash (the platform's only honest equivalent). Because the prompt prefix is as short and as stable as it gets, KV-cache reuse across a long session is maximized.

Quick start

# CLI / web profile
dsh plugin --profile web add dsh-win-minimal

# DSH Desktop
dsh plugin --profile desktop add dsh-win-minimal

(Replace --profile with the profile you actually use.)

Restart DSH, create a session, pick Minimal (Windows). The plugin materializes the preset under $DSH_HOME/.agent-presets/win-minimal/.

Manual install

Copy the two files in preset/ to $DSH_HOME/.agent-presets/win-minimal/. That is the whole preset.

Customization

Presets are declarative: edit agent.cordis.yml (persona text, tool rows), new sessions pick changes up immediately. Delete the directory to remove. With dsh-wsl-workspace installed, a wsl-win-minimal variant is generated automatically.

Design notes

• bash is one-shot, not persistent (the persistent PTY cannot run on Windows)
• materialization is idempotent and never overwrites user-edited files
• host-only, zero injects — a write failure can never break a profile boot
