dsh-perm-guard 🛡️

Auto-approval permission guard for DeepSeek Harness (dsh) web — the "middle tier" between workspace-write (asks too often) and danger-full-access (too open). Common operations like cross-directory edits, git commit/merge and builds run without approval prompts; destructive operations (deletes, disk ops, privilege escalation, curl|sh) always ask for human confirmation.

Unofficial project: independently developed and maintained by a community member, not an official DeepSeek product.

Auto Permissions settings page

Features

Two modes (switchable in the settings page, persisted):
- Standard — auto-approve inside the trust directories (workspace, sibling directories, custom list); outside + risky operations prompt.
- Aggressive — location-unrestricted: only destructive operations still prompt.
11 per-category tri-state switches (auto / ask / deny) with your personal defaults.
Audit trail — every decision is recorded (approved / forwarded to human / rejected) with timestamp and command summary.
Persistent config — ~/.dsh/perm-guard.json, survives restarts. Zero host dependencies.

Install

# DSH 0.1.7 and later:
dsh plugin --profile web add "github:a903067276-rgb/dsh-perm-guard#main"
# DSH 0.1.5 and older (this release needs 0.1.7+):
# dsh plugin --profile web add "github:a903067276-rgb/dsh-perm-guard#v0.2.10"

Then restart dsh web. Update: dsh plugin --profile web update dsh-perm-guard, restart.

Manual install fallback: see docs/install.md.

Usage

Auto button — in the composer tool row (left of the input box). Click to toggle auto-approval on/off (green = on). Off restores the host's default approval behavior completely.
Settings → "Auto 权限" (Auto Permissions) — total switch, mode selection (Standard / Aggressive), 11 category switches, trust directory editor, and the recent-decision audit list.
Rules apply to all sessions (including subagents) while enabled.

Mode defaults

Category	Standard	Aggressive
File edit (write/edit/cp/mv/mkdir)	auto (in trust dirs)	auto
Git local (commit/merge/rebase/checkout)	auto	auto
Build / test / install	auto	auto
Read-only queries (ls/cat/grep/git status)	auto	auto
Delete (rm, reset --hard, clean -fd)	ask	ask
Protected paths (.ssh/.aws/secrets/.env/system dirs)	ask	ask
Privilege (sudo, services, global installs)	ask	ask
Network download-execute (curl\|sh)	ask	ask
Git push	ask	auto
Publish / deploy	ask	auto
Disk / partition / device	ask	ask

Switching modes resets the category switches to that mode's defaults (adjustable afterwards).

Never auto-approved (all modes)

Deletion: rm, rm -rf / or ~ (circuit breaker, even with $(...) variants), git reset --hard, git clean -fd, Remove-Item
Disk: dd writing devices, mkfs/fdisk/wipefs/diskutil erase, writes to /dev/
Privilege: sudo/su, service management (launchctl/systemctl), recursive chmod/chown on / or ~
Network download-execute: curl|sh, wget|sh
Force push: git push --force / -f (rewrites history)
Writes to protected paths

Platform support

Platform	Status
macOS	✅ development environment
Linux	⚠️ expected to work
Windows	✅ adapted & field-tested (win32 path handling + PowerShell vocabulary, 2026-08-24)

Windows notes

Trusted dirs accept three absolute-path styles — C:\…, C:/…, /c/… (MSYS/Git-Bash) — normalized to C:/… on save; invalid entries are reported back by the UI instead of being silently dropped.
Classifier covers common PowerShell cmdlets: pipeline/formatting (Select-Object etc.) count as read-only; Invoke-RestMethod/iwr map to network; Stop-Process, reg add, schtasks /create etc. map to privilege (always human-confirmed); vssadmin delete shadows, bcdedit, diskpart are hard red lines.
gh CLI read-only subcommands (view/list/status…) auto-approve; write operations fall back to human confirmation.
Escalated retries (sandbox_permissions) raise exactly one confirmation card instead of two.

Requirements

DSH web >= 0.1.0-rc.6 (the approval system this plugin guards)
Version compatibility (best effort — the settings card uses dual-field key+id registration to satisfy both rc.6 (id) and rc.7+ (key); verified locally on rc.6/rc.8/0.1.1-rc.2/0.1.5-rc.1, not guaranteed on every DSH version):
- DSH 0.1.0-rc.6 and newer (incl. the 0.1.1 / 0.1.2 / 0.1.5 lines): try main (default) or v0.2.9 and newer.
- Conservative fallbacks (the last pre-0.1.1 build): DSH 0.1.0-rc.7/rc.8 → v0.2.7 (dsh plugin add github:a903067276-rgb/dsh-perm-guard#v0.2.7); DSH 0.1.0-rc.6 → frozen rc6-compat tag (no maintenance).
- ⚠️ On DSH 0.1.5+ do not install v0.2.8: it imports the removed settingsNamespace export and makes the whole plugin tree fail to load (the web app will not boot). Use main / v0.2.9+ instead.
pnpm in PATH — dsh plugin is a pnpm forwarder (needed for install/update)
- ✅ DSH 0.1.7 and later — use this release (v0.3.0): it declares peerDependencies: {"@deepseek-ai/dsh": ">=0.1.7-rc.1 <0.2.0"}, so a mismatched host refuses to load it with an explicit reason instead of failing quietly. Settings move to the 0.1.7 model (plugin Config, live-editable .volatile() fields), so changes apply without a restart.
- ⚠️ DSH 0.1.5 and older — install the previous tag v0.2.10: that line keeps the old behavior and uses no 0.1.7-only API.
- ⛔ Old plugin releases (up to v0.2.10) are not supported on 0.1.7 — disabling and re-enabling it from the plugin manager throws duplicate route, and configuration edits no longer apply. Upgrade the plugin together with the host.
Maintenance policy: this plugin keeps evolving with the latest DSH releases; compatibility with older DSH versions is best-effort only and not guaranteed going forward.

How it works

Interception before the host prompt — every approval request is intercepted before the host prompt; the actual command/target is classified, and safe operations are auto-answered allowed-once (~13ms, no popup), risky ones are forwarded to the human prompt.
Call lookup — an approval request carries no tool arguments, so the plugin resolves the real arguments from the session log by callId; DSH 0.1.5 removed Session.events, so it now reads the public snapshotEvents() (older hosts keep the events path). When neither is available it always falls back to the human prompt (safe default, never auto-allow).
Command-level firewall (tools/pre-execute) — dangerous categories are intercepted before the sandbox even rejects them.
Classification pipeline — the two modes set per-category defaults (Standard: trust directories; Aggressive: location-unrestricted), and the 11 tri-state switches (auto / ask / deny) fine-tune each category.
Audit + persistence — every decision is recorded with timestamp and command summary; approval decisions are always persisted via the host's approval/asked + approval/decided event pair.

Notes

DSH's sandbox has no OS-level network fence (unlike Codex): the plugin can only detect download-execute patterns (curl|sh) in command text, not block other network traffic.
Terminal sessions, subagent creation, model calls and MCP tools are outside the approval system entirely.
Commands whose text contains danger words (e.g. echoing "Remove-Item", or scripts embedding rule sources) are conservatively intercepted — expected, rare in practice.
The audit list is in-memory (60 entries) and resets on restart; approval decisions themselves are always persisted via the host's approval/asked + approval/decided event pair.

Coverage

All approval entry points in DSH are covered: bash, pwsh (PowerShell), and the write/edit file tools. MCP tools and other read-only tools have no approval mechanism and are unaffected.
Compound commands (a && rm -rf x): pure-word chains are split and evaluated per subcommand, taking the strictest result; chains containing variables/redirection/wildcards are treated conservatively as one unit.
Unknown commands always fall back to "ask" regardless of mode (safe default) — the classifier never auto-allows what it cannot parse.

How it compares to Claude Code / Codex

	Claude Code	Codex	dsh-perm-guard
Read-only command set	built-in, not configurable	sandbox	built-in + configurable
`rm -rf / ~` breaker	always prompts	sandbox blocks	always prompts (all modes)
Protected paths	yes	`.git`/`.agents`/`.codex`	`.ssh`/`.aws`/secrets/system dirs/`.git`
Network isolation	tool-level	OS-level (default off)	not available (DSH has no OS network fence; only `curl\|sh` pattern detection)
Approval categories	3 tool classes	5 granular switches	11 explicit switches + 2 modes
Auditing	prompts only	logs	in-plugin audit + host `approval/asked`/`decided` events

Configuration file

~/.dsh/perm-guard.json (created on first change):

{
  "enabled": true,
  "mode": "standard",
  "categories": { "fileEdit": "auto", "...": "..." },
  "trustedDirs": []
}

trustedDirs: extra absolute paths auto-approved in Standard mode (default: workspace + its sibling directories).
Trust directories are ignored in Aggressive mode (location-unrestricted).

Development

# hot-plug testing (no restart)
# 1. define a dynamic Cordis plugin with the same decision logic
# 2. cordis_run → verify → cordis_stop

# static bundle (this repo layout)
# symlink to ~/.dsh/profiles/web/node_modules/dsh-perm-guard
# add "dsh-perm-guard" to ~/.dsh/profiles/web/package.json dsh.profile.bundles
# restart dsh web
