dsh-auto-preset

dsh-auto-preset

A small DeepSeek Harness (DSH) plugin that remembers your last manual permission-preset choice for each session and restores it when you reopen that session.

Status: early / experimental. It talks to DSH's experimental permissionPresets API and was tested against @deepseek-ai/dsh 0.2.1-rc.2 and 0.2.1-rc.3 (the permission-presets code is identical in both). A future DSH release may change the API and break it.

Why

DSH's permission presets (workspace-write, danger-full-access, and the experimental auto = auto review) are stored per session. The default preset for a session is inferred from the process defaults, so a session can come back as the wrong mode after a restart — and the experimental Auto preset cannot be configured as the default preset at all:

// @deepseek-ai/dsh-permission-presets
if ("auto" in this.presets) throw new Error('permission: "auto" is reserved ...')
if (!Object.hasOwn(this.presets, defaultPreset)) throw new Error('permission: unknown default preset')

This plugin instead watches what you actually pick and puts it back.

Behavior

1. First time a session is opened: do nothing. The system default applies.
2. You switch a session to Auto review → remembered. Reopening the session restores Auto review.
3. You switch it to Full access → remembered. Reopening keeps Full access; the plugin will not force Auto back.
4. You later switch back to Auto review → remembered again. The plugin follows your last manual choice.

In one sentence: it follows your latest manual choice; it never overrides a choice you made.

State is kept in state.json next to the plugin (persists across DSH restarts). Delete that file to reset everything.

Install

From source

git clone https://github.com/heyuanliu3-byte/dsh-auto-preset.git
dsh plugin --profile web add link:/absolute/path/to/dsh-auto-preset

Then add "dsh-auto-preset" to the profile's bundle list (package.json → dsh.profile.bundles) and restart the DSH web server.

From npm

Once the package is published to npm:

dsh plugin --profile web add dsh-auto-preset

The plugin must be loaded after @deepseek-ai/dsh-experimental-auto-review, because the auto preset only exists while that bundle is live.

How it works

• session/created fires when a session enters the store — for a brand-new session and for a reopened one.
• session/event (permission/preset) tells the plugin which preset was selected. Events emitted before the plugin has "armed" a session (the initial pin) are ignored, and the plugin's own presets.set() calls are ignored via a reentrancy flag.
• On open, if a stored choice exists and differs from the current value, the plugin calls permissionPresets.set(session, storedChoice).

See lib/index.js — it is ~130 lines.

Caveats

• Experimental API: the permission-presets internals may change between DSH releases.
• Only permission/preset events are observed; a "custom" sandbox/approval combination is not represented as a preset and is therefore not restored.
• Web profile only in my setup; it does not require any non-official plugin in the desktop profile.
