Introduction
DSH Auto Preset Router
A DeepSeek Harness profile bundle that adds an Auto Agent Preset. The first
direct user prompt is classified by the fixed
deepseek-official/deepseek-v4-flash model, then the untouched prompt runs
under one of DSH's four shipped presets with the model selected for that
session.
Routing policy
| Target | Selected for |
|---|---|
standard | Web/current information, mixed work, general assistance, full tool ecosystem, or ambiguity |
code | Broad batch or parallel tool orchestration where PTC fan-out/fan-in is central |
minimal | Focused, self-contained implementation, debugging, refactoring, or algorithm work needing only persistent bash and the editor |
cordis | DSH preset, Cordis composition/plugin, host-plane, or runtime wiring work |
The classifier uses no tools, reasoning effort off, temperature 0, and a
16-token output limit. A failed or ambiguous classification falls back to
standard.
Install
DeepSeek Harness 0.1.0-rc.6 or a compatible later build is required.
dsh plugin --profile web add github:yhfgyyf/dsh-auto-preset-router
dsh web
For a separately installed TUI profile that composes the official
agent-presets service, install the bundle into that profile too:
dsh plugin --profile tui add github:yhfgyyf/dsh-auto-preset-router
dsh --profile tui
The bundle keeps the official roster service, contributes its package-owned
read-only preset through that roster, and sets the assembly default to auto.
It does not rewrite settings.yaml. An explicit user setting remains
authoritative; set this if needed:
agent-presets:
default: auto
After the first prompt is routed, DSH records agent-preset/selected before
the first real turn. The session is then locked to the selected preset by DSH's
normal non-empty-session rule.
Remove
dsh plugin --profile web remove dsh-auto-preset-router
dsh plugin --profile tui remove dsh-auto-preset-router
Existing sessions retain the preset recorded in their durable history. A local
$DSH_HOME/.agent-presets/auto directory, if present, is shadowed while this
bundle is installed and is never modified. Removing the bundle removes its
roster contribution on the next process start.
Privacy and failure behavior
The first prompt text is sent to DeepSeek V4 Flash even when the session uses a
different model. Prompts over 24,000 characters are reduced to their beginning
and end for classification. Image-only prompts and classifier failures route to
standard. The original message is not rewritten.
Development
npm test
npm run check
npm pack --dry-run
With a configured TUI profile and DeepSeek credentials, the optional live gate runs one fresh session for each target (and creates four short session logs):
npm run test:live:tui
The repository uses the current DSH plugin distribution contract:
package.json declares dsh.bundle.patch, and cordis.patch.yml composes the
package through dsh plugin --profile … add ….
