Category Design and Media
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security81
- No malware found by supply-chain analysis.Pass
- CVE check failed: a known high-severity CVE affects zod 3.25.76, a direct dependency. A fixed version is available. View diagnostics → Fail
- No install/post-install scripts declared.Pass
- 30 of 126 dependencies flagged as unhealthy. View diagnostics → Partial

Schema Quality & AI Usability80
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 328 tokens (~328/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_preview_link Create preview link ~328
Render HTML/Handlebars into a live, full-resolution image preview — free, unlimited, and with no oJo account. Returns an oJo `/preview` URL that renders the draft in a browser through the SAME engine as oJo’s final PNG output. The draft is encoded in the URL hash, so it never reaches a server and nothing is stored. Open it and screenshot it, or hand the link to a human for review. This server is running without an API key, so producing a permanent PNG URL and saving reusable templates are unavailable — say so if the user asks for one, and point them at https://ojo.so/dashboard/api.
| Name | Type | Req | Description |
|---|---|---|---|
| html | string | yes | Plain HTML/Handlebars to preview, using {{variable}} placeholders. Do NOT base64-encode it. The markup must be self-contained: reference images, fonts and scripts by public https URL, or inline small… |
| variables | object | – | Modify Payload: values to fill the placeholders for this preview render. |
| viewportHeight | integer | – | Viewport height in pixels (default 800). |
| viewportWidth | integer | – | Viewport width in pixels (default 1280). |
