dsh-workspace-groups

A DeepSeek Harness (DSH) web client plugin: a complete workspace grouping manager.
Turns the GUI sidebar's two-level workspace list (Projects → Sessions) into a
three-level Category folder → Project folder → Session tree, backed by full
group-management capabilities: manual group creation, rename/delete of any group,
drag-and-drop grouping, free ordering of projects and groups, rule-based
auto-classification, and tree-shaped search. Every action takes effect
immediately and persists, with zero intrusion on official data.

Features

Grouped tree browsing

• Group folder → project folder → session row, both levels collapsible; expansion state
  persists independently (dsh.workspace.groups.view.v1, survives refresh/restart)
• Top-level project rows: ungrouped projects (matching no rule, dragged out of a group,
  or returned by a group delete) render as plain rows right after the group folders, at the
  same level — there is no "未分类" bucket

Group management (full lifecycle)

• Create groups manually: the "新建分组" button in the section header shows the group
  immediately (empty groups render too)
• Rename / delete any group: every group row (rule categories included) has a hover
  ⋯ menu; deleting a group sends all of its projects back to the top level;
  rule-category rename/delete rides the overlay (renamed / hidden),
  the rule YAML stays untouched
• Rule-based auto-classification: the sidecar YAML declares category rules (pathPrefix /
  pathExact / nameContains / basenameContains); edit the config to adjust grouping
  without touching code

Drag-and-drop grouping + ordering

• Drag projects into groups: drop on any group row or on a project row inside a group
  (cross-group move = overrides the rule classification)
• Drag projects OUT of a group: the entire top-level area is the move-out drop
  target while dragging, shown with an insertion line (not a highlight box) — drop on
  any top-level row (reorder before/after it), on the blank space below the last row
  (append), or, when the top level is empty, a standalone line under the last group
  folder; grouped projects also have a "移出分组" menu item (rule-classified ones included)
• Reorder projects inside a group: top half of a project row = insert before it,
  bottom half = insert after it
• Reorder top-level projects: top-level rows are draggable too — top half = insert
  before, bottom half = insert after; the top-level order persists under
  workspaceOrder["__topLevel__"]
• Reorder groups: group rows are draggable — top half of another group row = move before it,
  bottom half = move after it
• Insertion position indicator: a 2px line (above/below the row) shows the exact drop
  point while dragging — what you see is where it lands
• Level-aware folding, auto-restored: dragging a project folds every project row
  (grouped AND top-level; group rows stay expanded); dragging a group folds every group
  (project rows keep their expansion) — dragend restores the pre-drag expansion snapshot
• Distinct row icons: group rows use a folder glyph, project rows a project glyph
  (same as the official workspace browser) — groups and projects are easy to tell apart

Search & operations

• Tree-shaped search: results keep the three-level structure (category → project → matched
  session), matched rows highlighted with a content snippet, 250ms debounce
• No regression on workspace/session actions: Add Workspace, project rename/delete,
  session new/open/rename/fork/archive

Persistence & zero intrusion

• Every manual action (groups, grouping, ordering, rename, hide) is written to the plugin's own
  overlay (~/.dsh/workspace-groups.manual.json), validated by the host and written
  atomically (a malformed write returns 400 and keeps the previous file)
• Zero intrusion: never touches ~/.dsh/storages/workspace.json, session on-disk
  structures, or the official @deepseek-ai/dsh-client-ui-workspace package; the rule YAML
  is never rewritten
• Self-contained artifact: lib/ is prebuilt and shipped with the repo — installing from
  Git runs no dependency scripts

How it works

• The plugin is a client plugin registered into the official sidebar shell's
  sidebar.workspaces slot (kind: 'single') at priority: -1, replacing the official
  WorkspaceBrowser (registered at priority 0; lowest priority wins in a single slot).
• All data comes from the runtime API: the useWorkspaces / useSessions global hooks and
  ctx.workspaces.* / ctx.sessions.* — grouping is purely a presentation-layer transform.
• The host half does two things: parses the sidecar YAML and merges it with the runtime
  overlay, served to the client via GET /workspace-groups/config (Cache-Control: no-cache);
  and PUT /workspace-groups/manual accepts the full overlay (manual groups, per-workspace
  grouping overrides, group/project ordering, rule-category renames and hides), validates it
  and writes it atomically to $DSH_HOME/workspace-groups.manual.json.
• Classification priority: manual override (written by drag/menu; null = forced
  top-level, rules ignored) → YAML rule classification (hidden rule categories are inert)
  → top level (ungrouped projects render as top-level rows). The YAML is never
  rewritten.

Install (GitHub distribution)

Prerequisite: DeepSeek Harness
installed (dsh available) with a target profile initialized (e.g. the built-in web).

dsh plugin --profile web add github:z-col/dsh-workspace-groups

This automatically:

1. Adds "dsh-workspace-groups": "github:z-col/dsh-workspace-groups" (pinned to
   version/commit) to dependencies in ~/.dsh/profiles/web/package.json
2. Appends "dsh-workspace-groups" to dsh.profile.bundles
3. Runs pnpm install and validates the bundle layer

Restart the web profile after installing (both the bundle and the host half only load
on restart):

# Stop the running dsh web process and start it again, e.g.:
dsh web

Verify the install:

dsh --profile web --dump-config | grep -A3 workspace-groups
# expect: - id: workspace-groups / name: dsh-workspace-groups / config: {}
curl http://127.0.0.1:3080/workspace-groups/config
# expect: the sidecar YAML parsed as JSON

Uninstall

dsh plugin --profile web remove dsh-workspace-groups

This removes the dependency from dependencies and the matching line from
dsh.profile.bundles. A web profile restart is required for it to take effect.

Manual equivalent (pick one, don't repeat): edit ~/.dsh/profiles/web/package.json,
remove the dsh-workspace-groups line from dependencies and "dsh-workspace-groups"
from dsh.profile.bundles, then run pnpm install in that directory.

Classification config (sidecar)

Default location ~/.dsh/workspace-groups.yaml (override the home dir with the
$DSH_HOME env var). Template: workspace-groups.example.yaml at the repo root.

categories:
  - name: DSH 插件
    rules:
      - pathPrefix: /Users/zcol/Project/SkillsManagePlugins
      - nameContains: 插件
      - basenameContains: plugin
  - name: 个人项目
    rules:
      - pathPrefix: /Users/zcol/Project/yeluzi

Rule fields (each rule is an OR — any match classifies; categories are matched in order,
first match wins):

Projects matching no category — or moved out of a group — render as top-level project
rows (same level as the group folders), never hidden.

Manual groups & drag-and-drop grouping (runtime overlay)

Besides the rule YAML there is a plugin-owned runtime overlay, recording only manual
UI operations, at $DSH_HOME/workspace-groups.manual.json (e.g. ~/.dsh/workspace-groups.manual.json):

{
  "categories": ["临时", "归档"],
  "assignments": {
    "a1b2c3d4-e5f6-7890-abcd-ef1234567890": "临时",
    "a1b2c3d4-e5f6-7890-abcd-ef1234567891": null
  },
  "categoryOrder": ["临时", "DSH 插件"],
  "workspaceOrder": { "临时": ["a1b2c3d4-e5f6-7890-abcd-ef1234567890"] },
  "renamed": { "DSH 插件": "插件集" },
  "hidden": ["文档"]
}

• categories — manually created group names (no rules; empty groups render too).
• assignments — workspace → group classification overrides keyed by the stable workspace id
  (renames don't affect it). Takes precedence over YAML rules; a value of null means
  forced top-level (even when a rule would match).
• categoryOrder — group display order (top-level rows are not listed here; they always
  render after the group folders).
• workspaceOrder — per-group manual ordering of projects (written by drag ordering).
• renamed / hidden — UI rename/delete of rule categories (a hidden category's rules become
  inert and its matches go top-level); the rule YAML stays untouched.
• The file is written in full by the browser UI (PUT /workspace-groups/manual, atomic
  replace); manual edits also take effect on next load. A malformed write returns 400 and
  keeps the previous file — the rule YAML is never at risk.

Topics

This repo targets automatic discovery by the DSH plugin ecosystem (community marketplaces
scan GitHub topics). Already set:

• dsh-plugin (core tag; 1024Store
  and similar marketplaces discover by this topic periodically, validating
  package.json + the plugin bundle manifest (cordis.patch.yml))
• deepseek-harness / deepseek-harness-plugin / dsh
• sidebar / workspace / workspace-groups

package.json also provides keywords for npm/search indexing.

Development

pnpm install
pnpm typecheck   # host + client dual-program type checking
pnpm test        # core rules, overlay, tree derivation unit tests
pnpm build       # build lib/ (node half + client bundle)
pnpm watch       # tsdown watch (client HMR)
node scripts/verify-groups.mjs   # real-browser CDP verification (host restarted; self-spawns a headless Chrome, auto-restores the scene)

Artifact contract (mirrors the official client packages):

• lib/index.js — host half (ESM; reads the sidecar + /workspace-groups/config route;
  js-yaml inlined, no runtime dependencies)
• lib/client.js — browser half (window.__ModuleLoader__.load({id, factory}); only
  requires platform seeds: react / react/jsx-runtime / @deepseek-ai/dsh-client-runtime/client /
  @deepseek-ai/dsh-client-ui-primitives; cross-plugin value imports are rejected at build
  time by the purity gate)
• lib/types/** — declaration files

Release strategy: lib/ build artifacts are committed (no prepare script), so
dsh plugin add github:... never runs third-party build scripts — install and use.

Verification record

• v0.1/v0.2 real-combination verification (headless Chrome + CDP): three-level tree takeover,
  correct classification, expansion persistence, search keeps workspace membership;
  workspace.json / session on-disk / official store: zero intrusion.
• v0.3 real-browser verification 24/24 (scripts/verify-groups.mjs: create group / drag /
  order / collapse / rule-category menu / rename / delete-back-to-top-level /
  scene restore; zero-intrusion assertions).
• v0.4 real-browser verification 30/30 (added: insertion indicator, project/group
  downward drag (bottom half → insert after the target), group upward drag (top half →
  move before the target); scene restored).
• v0.4.1 real-browser verification 34/34 (added: dragging projects OUT of a group —
  top-level drop zone / top-level rows = forced top-level; grouped projects get the
  "移出分组" menu item).
• v0.5 real-browser verification 35/35 (model change: no "未分类" bucket — top-level
  project rows, group delete returns members to the top level, drag/menu move-out to the
  top level, no uncategorized bucket anywhere in the tree; scene restored).
• v0.6 real-browser verification 40/40 (added: level-aware folding — dragging a project
  folds project rows only (group rows stay open), dragging a group folds group rows only;
  dragend restores the pre-drag expansion snapshot).
• v0.6.1 real-browser verification 42/42 (added: the whole top-level area as the move-out
  drop target with a visible landing highlight; distinct folder-vs-project row icons;
  scene restored).
• v0.7 real-browser verification 46/46 (added: top-level landing shown with an insertion
  line instead of a highlight box — reorder before/after a top-level row, append below
  the last row, or a standalone line when the top level is empty; top-level projects are
  reorderable with their order persisted under workspaceOrder["__topLevel__"]; also
  fixed a host validation bug that rejected __topLevel__ and a drop-positioning bug where
  dropping between two top-level rows landed above the first; scene restored).
• 66 unit tests green (vitest: core / manual / tree / store).
• Reproducible automated verification: node scripts/verify-groups.mjs (host restarted).
