Synchronize the plugin-list configuration of DeepSeek Harness (DSH) clients through any S3-compatible object store — AWS S3, MinIO, RustFS, Cloudflare R2, Aliyun OSS (S3 gateway), etc.

DSH 插件列表多端同步：把当前客户端的插件清单上传到任意 S3 兼容存储，在其他客户端下载并应用，实现多端插件配置一致。

What gets synced

The plugin-list configuration is exactly two files in a DSH profile:

Both directions are MERGE-only by default. Uploading never deletes remote-only plugins; downloading never removes a locally installed plugin and never downgrades a locally higher version (per-package the HIGHER side wins; an older remote revision is reported as kept-local, never applied).

Force overwrite exists as an explicit, one-shot, never-persisted opt-in — see Force overwrite under Use.

• Official @deepseek-ai/* bundles are never synced: they track each client's own DSH runtime, and syncing them would re-create the peer-dependency breakages the DSH plugin gate exists to prevent.
• LLM provider config is excluded by default (the config: blocks of rows like llm-pi-ai / agent-default-model carry baseURLs and model catalogs). Enable includePatchConfig if you want it synced; when disabled, those rows keep only their structural keys (id / name / disabled).
• dsh-plugin-list-sync itself is skipped (self-bootstrap): it must be installed on each client manually — once.

Install

dsh plugin add smellgamed3/dsh-plugin-list-sync

or from a checkout:

dsh plugin add file:C:/path/to/dsh-plugin-list-sync

Configure

Open Settings → Plugin Sync in the DSH web UI and fill in:

• S3 endpoint — e.g. https://s3.amazonaws.com, http://127.0.0.1:9000 (MinIO/RustFS)
• Region — real region on AWS; auto (maps to us-east-1) works for MinIO/RustFS
• Bucket + optional key prefix
• Path-style addressing — on by default (MinIO/RustFS need it); turn off for virtual-host-style endpoints
• Allow plain HTTP — opt-in only for local/test endpoints
• Request SSE-S3 AES256 encryption — off by default; enable only when the S3 backend has SSE-S3/KMS configured (keep it off for RustFS without RUSTFS_SSE_S3_MASTER_KEY)
• Sync LLM provider config — off by default; carries the full patch layer including private gateways and model catalogs
• Machine label — recorded in the manifest's source.label for audit, e.g. office-desktop

Credentials are never written to config files and never included in the sync manifest. Provide them either via:

• the settings page — AccessKey / SecretKey fields with Save/Clear buttons; stored locally in <profile>/.dsh-plugin-list-sync/credentials.json (priority over env vars), or
• environment variables DSH_PLUGIN_SYNC_S3_KEY / DSH_PLUGIN_SYNC_S3_SECRET (used when no saved pair exists).

Use

Settings page buttons: Preview diff (dry-run against the remote manifest), Upload current list, Download && apply, Rollback (restores the latest snapshot; every apply snapshots both files first). Every operation is a merge by default; see below for the force overwrite switches.

Force overwrite (dangerous, opt-in per operation)

A red-bordered Force overwrite block at the bottom of the settings page holds two independent switches. They are explicit one-shot operations:

Safety constraints:

• Never persisted: the ticks live only in component state (not in localStorage, not in settings.json, not anywhere); they apply to the next operation only and reset automatically after it, successful or not.
• Double confirmation (force local): you must first re-preview with the tick ON to see the replace plan (applying without it is rejected server-side with confirm-required), then pass a confirmation dialog that spells out the exact removals/downgrades.
• Official components are never sacrificed: even in replace mode, @deepseek-ai/* official bundles, this plugin itself, and LLM provider config: blocks stay verbatim.
• Snapshots still run first: a replace apply snapshots both files and can be rolled back.
• Command surface is limited: upload --force replaces the remote and diff --force previews the replace plan, but pull --force is refused — force-overwriting local must go through the settings page's confirmation flow.

Command surface (any DSH chat):

/plugin-sync status
/plugin-sync upload [--force]
/plugin-sync diff [--force]
/plugin-sync pull
/plugin-sync rollback [snapshot-id]

Semi-automatic sync

Both automation switches are off by default. After saving settings, the Host can debounce-upload local package.json / cordis.patch.yml changes and periodically check remote differences. It never downloads, installs, removes, or applies remote plugin configuration automatically; a user must still preview and explicitly apply any remote change. Automatic uploads use the same merge semantics as the manual button.

Non-secret automation settings live in <profile>/.dsh-plugin-list-sync/settings.json; credentials remain separate and never enter a manifest.

Safety model

1. Merge-only by default — upload merges local INTO the remote manifest (remote-only plugins are preserved); apply merges remote INTO the local profile (local-only plugins survive, local versions never move backwards). Force-replace requires an explicit, per-operation, never-persisted opt-in with confirmation.
2. Download-side strict validation — a remote manifest is applied only after schema whitelisting (format/version/revision, npm-style package names, bounded sizes). Anything outside the schema refuses to apply; a corrupt remote object also refuses to be overwritten by an upload (unless force is deliberately ticked).
3. Snapshot-first apply — package.json + cordis.patch.yml are captured to .dsh-plugin-list-sync/snapshots/ before any write; rollback is one command and itself snapshots first.
4. Revision monotonicity — uploads increment the remote revision; a pull never applies an older revision silently.
5. Same-origin fence — every mutating route rejects cross-site requests (Origin/Host discipline).
6. Optimistic locking — uploads carry If-Match with the observed ETag where the server supports it.
7. Official components stay local — @deepseek-ai/* bundles track each client's DSH runtime and are never synced across machines.
8. Minimal peer surface — the only peer dependency is @deepseek-ai/cordis (ships with DSH). Everything else (commands, webServer, pluginManager, credentials, settings) is feature-detected at runtime; a host missing a service keeps that surface disabled instead of failing to load.

Manifest format

{
  "format": "dsh-plugin-list-sync/manifest",
  "version": 1,
  "revision": 42,
  "updatedAt": "2026-09-29T08:00:00.000Z",
  "source": { "label": "office-desktop" },
  "runtime": { "dshVersion": "0.2.0-rc.1" },
  "packages": { "dsh-context": "0.59.0" },
  "bundles": ["dsh-context"],
  "patch": { "kind": "rows", "rows": [{ "id": "cost-meter", "disabled": true }] }
}

One JSON object per profile: s3://<bucket>/<prefix>/<profile-name>.json.

Development

pnpm run check          # syntax checks + core regression suite
pnpm test               # core regression suite
pnpm run test:s3-mock   # terminal A: local SigV4-validating S3 mock
pnpm run test:e2e       # terminal B: full S3 merge/force upload + apply/rollback flow

The e2e suite runs against an isolated throwaway profile (never your real one) and covers both merge and force semantics end to end.

Pure Node built-ins (node:https, node:crypto, node:fs, node:path); zero runtime dependencies; SigV4 implemented in ~200 lines (lib/s3.js).
