dsh-auto-approval

dsh-auto-approval

English | 中文

A fourth permission preset for DeepSeek Harness: pick Automode in the composer's permission dropdown and the session runs on full access with an LLM classifier as the only gate before every tool call. No approval prompts — the classifier answers for you.

The permission model stays 3 + 1: the three official sandbox levels, plus one auto tier. Selecting any other preset turns the plugin off; there is no second switch.

0.2.0 is a rewrite of the 0.1.x line. The on/off switch became a permission preset: install, pick Automode, done. Upgrading? See Upgrading from 0.1.x.

Demo

The recording: pick Automode, send one prompt (create a directory, write a file, read it back, then run echo danger_test). The agent runs the file steps unattended — the classifier allows them (L1-deep / whitelist) — and the final command is blocked by a hard rule (L0-deny). The chip's dialog shows both verdicts and the cumulative counts.

How it works

model wants a tool call
        │
        ├─ preset ≠ automode ──────────────► untouched (official behavior)
        │
        └─ preset = automode
                 │
                 ├─ L0 rules (hard deny) ───► deny   (rm -rf /, curl | sh, self-kill …)
                 ├─ trusted tools / bash prefixes ──► allow
                 └─ L1 classifier ──────────► allow | deny   (fail-closed: timeout/parse/no-model → deny)

• L0 — regex deny rules, self-kill guard, trusted-tool and bash-prefix allowlists. Deterministic, no model call.
• L1 — the latest real user message plus the bare tool call go to a two-stage classifier (fast single-token filter → deep CoT check when flagged). Tool output is never shown to the classifier, so injected content cannot talk it into an allow.
• Fail-closed — a timeout, a parse failure, or a missing model denies the call.

The preset writes the same knobs as danger-full-access (full access + approval never), so nothing else asks the user either. What distinguishes the two entries is the plugin's gate — and the official preset service keeps the last selected name, so the dropdown shows which one you picked.

Install

dsh plugin --profile web add dsh-auto-approval

Just published a new version? pnpm 11 refuses versions younger than 24 hours (minimumReleaseAge, a supply-chain default), so add dsh-auto-approval resolves the *previous* release for the first day. Install the exact version (dsh plugin --profile web add [email protected]) or add the package to the profile's pnpm-workspace.yaml:

复制代码

minimumReleaseAgeExclude:
  - dsh-auto-approval

Then pick Automode in the permission dropdown next to the composer (or /permission automode). The first time you do so in a browser, a one-time notice explains the trade-off (the official "Enable Full access?" gate is keyed to danger-full-access and never fires for a custom preset). The Auto chip then appears beside the preset selector with cumulative allow/deny counts and a click-through decision table.

Source install: clone the repo, pnpm install && pnpm run build, then dsh plugin --profile web add link:/<path>.

Upgrading from 0.1.x

0.2.0 keeps the package name, the auto-approval: settings section and every config key, so an upgrade needs no config changes. What changed:

# 1. drop the old companion package (its browser half now ships in the main package)
dsh plugin --profile web remove dsh-client-ui-auto-approval

# 2. upgrade
pnpm --dir "$DSH_HOME/profiles/web" up dsh-auto-approval

# 3. restart dsh, then pick Automode in the permission dropdown

If your settings.yaml has no classifier configured (classifierFastProvider / classifierFastModel), automode now fails closed — configure one, or only trusted tools and allowlisted commands will run.

Configuration

$DSH_HOME/settings.yaml, hot-reloaded:

automode:
  denyPatterns:
    - 'rm\s+(-[a-z]*[fr][a-z]*\s+)*/\s*$'
    - 'curl\s+[^|]*\x7c\s*(ba)?sh'
  autoApproveTools: [read, write, edit, glob, grep, ls]
  bashCommandPrefixes: [ls, pwd, git status, git diff, pnpm test]
  classifierFastProvider: deepseek-official
  classifierFastModel: deepseek-v4-flash
  classifierDeepProvider: deepseek-official
  classifierDeepModel: deepseek-v4-pro
  classifierGuidance: 'Prefer allowing read-only and test commands.'

Every key is optional. denyPatterns / autoApproveTools / bashCommandPrefixes replace the defaults wholesale (YAML arrays do not merge), so restate the values you want to keep.

Without classifierFastProvider/classifierFastModel there is no L1, and automode fails closed: only trusted tools and allowlisted commands run, everything else is denied. That is deliberate — a session with no classifier is not a safety net, and silently allowing everything would make the gate a rubber stamp.

Permissions and data

Compatibility

Tracks the latest official DeepSeek Harness release. Currently verified against @deepseek-ai/dsh 0.1.2-rc.1 (install → boot → real tool-call decision in a disposable DSH_HOME). Older releases are not supported.

The bundle patch restates the official preset table, so a base release that adds a preset needs this file updated too.

Development

pnpm install
pnpm run typecheck
pnpm run test
pnpm run build     # lib/index.js (host) + lib/client.js (browser)
