What it does

Library Curator is an agent skill from nexu-io/open-design. Search the OD Library (the global asset registry) and apply matching assets into the current project mid-task. Use when the user asks to reuse an image they captured/uploaded earlier, "pull a logo/screenshot from my library", or to find and drop a stored asset into the page being built.

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes… The licence is Apache-2.0.

When your agent uses it

The user asks to reuse an image they captured/uploaded earlier
Pull a logo/screenshot from my library
Find and drop a stored asset into the page being built

Example prompts

“pull a logo/screenshot from my library”
“/library-curator”

Requirements

A credential in OD_TOOL_TOKEN

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

Search with a tight query for the kind you need.
Pick the best result by dimensions / title / source.
Apply it to get a project-relative path.
Wire that path into the artifact you're editing.

What it can do on your machine

Read from SKILL.md and the folder at commit 17e2559. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- OD_TOOL_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Library Curator loads about 574 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 229 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~76
When it runs · the whole SKILL.md, loaded when a task matches: ~574

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: library-curator
description: Search the OD Library (the global asset registry) and apply matching assets into the current project mid-task. Use when the user asks to reuse an image they captured/uploaded earlier, "pull a logo/screenshot from my library", or to find and drop a stored asset into the page being built.
triggers: from my library, library asset, use the image I captured, insert from library
od.mode: utility
od.category: assets

library-curator

Reuse assets that already live in the user's OD Library — images captured with the OD Clipper, manual uploads, agent-generated media, and design-system material — without asking the user to re-upload them.

When to use

The user references an asset they already have ("the screenshot I clipped", "my logo", "that hero image from earlier").
You need an image for the page you're building and the user prefers their own library over freshly generated media.

Tools (tool-token track)

Both endpoints authenticate with the run's tool token (OD_TOOL_TOKEN, injected by the daemon) and operate on the project the run belongs to.

Search

POST /api/tools/library/search

json

{ "query": "blue hero background", "kind": "image", "limit": 20 }

Returns { "results": [{ "asset": { "id": "...", "kind": "image", "sourceTitle": "...", "width": 1600, "height": 900, "sources": [...] }, "score": 0 }], "semantic": false }.

semantic: false means keyword/metadata matching (no embedding model configured). Filter and rank the results yourself from the asset metadata.

Apply

POST /api/tools/library/apply

json

{ "assetId": "<id from search>", "dir": "assets" }

Copies the asset into the project (default subdir library/, or the dir you pass) and returns { "relPath": "assets/<hash>.png" }. Reference that relPath from the HTML/CSS you write (e.g. <img src="assets/ab12cd34ef.png">).

Recipe

Search with a tight query for the kind you need.
Pick the best result by dimensions / title / source.
Apply it to get a project-relative path.
Wire that path into the artifact you're editing.

If search returns nothing, fall back to media generation rather than guessing a path — never invent a relPath that apply did not return.
