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
- First time a session is opened: do nothing. The system default applies.
- You switch a session to Auto review → remembered. Reopening the session restores Auto review.
- You switch it to Full access → remembered. Reopening keeps Full access; the plugin will not force Auto back.
- 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.
