dsh-moodboard

English · 中文

A visual reference moodboard for DeepSeek Harness. Collect screenshots and inspiration images in the Web UI, tag and annotate them, pin the ones that define your app's visual language, and let the agent read that style guide before it generates or restyles UI.

Preview

The screenshot below shows the plugin panel. For a local walkthrough after installation:

1. Open Moodboard from the sidebar and add a reference image.
2. Give it a tag and a note describing the styling you want, then pin it.
3. Use the composer’s Moodboard button to add the reference directive to your draft. Review and send it when ready.

Quick start

dsh plugin --profile web add dsh-moodboard

Restart the Harness (or refresh the Web UI). It adds a Moodboard entry to the sidebar.

What you get

• Moodboard panel in the Web UI (sidebar icon): drag-and-drop, clipboard paste or file-picker upload; gallery of thumbnails with drag-to-reorder and multi-select bulk actions; tag filter; and an active style-guide strip.
• Modern, theme-aware UI: harness-native styling built entirely on DSH theme tokens (surfaces, borders, text, buttons, inputs, links), with warm accents kept to a subtle tint on the active style-guide surface and pinned affordances. Includes a hero-style active style guide, sticky search/filter toolbar, icon-only card actions with hover affordances, a floating multi-select command bar, a sticky inspector footer and a bottom-sheet inspector on narrow screens. Motion honours prefers-reduced-motion; focus rings, live regions and labelled controls are preserved.
• Capture: drop files from Finder, paste images with ⌘V/Ctrl+V, or use the Paste / Add images buttons. Every image is downscaled and stored durably.
• Organize: drag cards to set the gallery order, Shift/Cmd-click to select several, then pin, unpin, tag or remove them in one action.
• Find & inspect: search by name, tags, notes or source (combinable with the tag filter), and open any reference in a full-size lightbox with previous/next navigation and keyboard support.
• Keyboard & accessibility: ? opens the shortcuts list, / focuses search, ⌘A selects all, ⌘⇧A inverts, Alt+←/→ reorders a focused card; controls keep visible focus rings, dialogs are labelled and keyboard-trapped, and selection/filter changes are announced through live status regions.
• Tag smartness: autocomplete from the tags already on the board, and a tag manager that renames or merges a tag across every reference (with per-tag counts).
• Reuse: copy tags/notes/source from one reference and paste them into another.
• Per-image metadata: tags, notes, source URL, name — editable in a metadata panel, with pin / replace / remove actions.
• Active style guide: pin one or more references. The agent treats pinned images as the source of truth for typography, color, spacing, radius, iconography and component styling.
• Agent integration:
  • moodboard tool with active / query / list / get / brief actions. active and query return the reference images themselves as image content blocks, so the model analyses the actual pixels, plus tags, notes and source URLs.
  • A system-prompt section tells the agent the moodboard exists and to load it before designing UI.
  • A compact Moodboard button in the composer inserts a directive into the draft that points the agent at the pinned references (it never sends).
• Persistence: metadata survives restarts in <DSH_HOME>/moodboard/board.json; image bytes live in the durable attachment store (<DSH_HOME>/attachments/v1). Survives sessions, reloads and restarts.

Requirements

DeepSeek Harness >=0.2.1-rc.3 <0.3.0-0 with the Web profile (the Host half needs attachments, tools, systemPrompt, webServer, and connection; the browser half needs the slots and locale services).

Install

Renamed in 0.2.7. This plugin publishes as dsh-moodboard. The earlier scoped name @stijnus/dsh-moodboard was unpublished, so pins to it now return 404 — install dsh-moodboard and remove the old entry from your profile.

Unpublished earlier name aside, installation is one command:

From npm once a release is published, through the Plugins page or plugin_manager install_bundle:

plugin_manager install_bundle target: "dsh-moodboard"

Manual equivalent (installs the package into a profile; the bundle still has to be enabled through the Plugins page):

dsh plugin --profile <profile> add dsh-moodboard

Reload the Web UI if the sidebar icon does not appear immediately.

Development

git clone https://github.com/Stijnus/dsh-moodboard.git
cd dsh-moodboard
npm test              # syntax checks + node:test smoke suite
npm run pack:check    # verify the published tarball file list

Install a local checkout into a profile for manual testing:

plugin_manager install_bundle target: "/absolute/path/to/dsh-moodboard"

The current build contract for the Host and Client halves is docs/CONTRACT.md.

Agent API

Tool moodboard

action	meaning
active (default)	pinned style guide, or the whole board when nothing is pinned. Returns metadata and the images themselves.
query	filter by tag(s): tags: ["dark","typography"], match: "any" | "all". Returns matching images.
list	metadata for every image, no image bytes (cheap overview).
get	one image by id, with complete notes, tags and source URL.
brief	text-only style brief (names, tags, notes, sources).

includeImages: false suppresses image content blocks. Image content is capped at 6 per call. active and query return abbreviated overviews with reference IDs; use get for complete metadata, or list to find all reference IDs.

HTTP endpoints

The Host half serves one authenticated prefix route /moodboard (owner session cookie required, same origin as the Web UI). The agent normally uses the tool; these endpoints exist for the panel and for programmatic reads:

Method + path	Purpose
GET /moodboard/api/state	full board + guide summary
POST /moodboard/api/images	upload { data, mediaType, name?, tags?, notes?, sourceUrl? }
PATCH /moodboard/api/images/<id>	update name, tags, notes, sourceUrl, pinned, order
POST /moodboard/api/images/<id>/replace	replace bytes, keep metadata
DELETE /moodboard/api/images/<id>	remove
POST /moodboard/api/images/reorder	set the complete gallery order { ids: [...] }
POST /moodboard/api/images/bulk	bulk { ids, pinned?, addTags?, removeTags?, delete? }
POST /moodboard/api/tags/merge	rename/merge { from, to } across the board
GET /moodboard/api/active	active guide with tags/notes/sources/brief
GET /moodboard/api/query?tag=…&match=any	tag lookup
GET /moodboard/api/health	liveness + image count
GET /moodboard/image/<id>?v=<attachmentId>	normalized image bytes for that revision

All JSON responses use { ok: true, … } or { ok: false, error: { code, message } }.

Data

• Metadata: <DSH_HOME>/moodboard/board.json (atomic writes; corrupt files are backed up as board.corrupt-<timestamp>.json and the board starts empty).
• Images: content-addressed in the harness attachment store. They are normalized on upload (WebP/JPEG, max edge 1600 px from the UI) and never deleted automatically; removing a board entry only removes the reference.

Visual language

Plugin chrome uses Harness theme tokens (--dsw-alias-*) so the panel follows light/dark switching. Image thumbnails are the user's own artwork.

Limits

• Up to 200 images, 20 tags per image (48 chars each), 4000-char notes.
• Uploads are re-encoded client-side (max edge 1600 px, q 0.85) before upload.
• The HTTP endpoints are owner-authenticated for same-origin/browser callers. A bash/curl caller has no session cookie — use the moodboard tool instead.

Releases and provenance

Releases are tag-driven and published from GitHub Actions using npm trusted publishing (OIDC). No long-lived npm token is stored in the repository: npm only accepts a publish from this repository's release.yml workflow at a tagged commit, and the short-lived credential minted for that run cannot be reused elsewhere.

Every release from 0.1.1 onward is published with a provenance attestation that binds the tarball to this repository, the workflow file, and the commit. The npm package page shows the Provenance badge for those versions. 0.1.0 was published manually before the publisher was configured, so it has no attestation.

Verify a release:

npm view dsh-moodboard@<version> dist.attestations
npm view dsh-moodboard@<version> dist.integrity

The attestation URL resolves to the signed in-toto statement; the matching Sigstore transparency-log entry is printed in the release workflow log. The one-time publisher setup, tag/release steps, and post-publish checks are in RELEASING.md; version history is in CHANGELOG.md.

If the saved board cannot be read or its recovery backup cannot be written, the plugin reports a storage error and blocks changes. Correct the storage problem and reload the plugin; existing board data is retained.
