open-webui

open-webui is a plugin for Claude Code from air-gapped/skills. Its manifest loads nothing; the 3 skills it bundles cost 474 tokens per session together, scanned A, original, MIT.

An operations suite for Open WebUI, a web interface for using and administering AI models. It covers its REST API, user access, model catalogs, retrieval-augmented generation (RAG), embeddings, reranking, and multi-server deployment.

In plain words
What is it for?
Use it to manage users and groups, synchronize model catalogs, configure RAG pipelines, connect embedding and reranking services, and run Open WebUI with WebSockets and Valkey Sentinel.
Why use it?
AI web interfaces become difficult to operate when access control, document search, WebSockets, and shared state must work across several servers. This helps connect and troubleshoot those parts.

Security

Grade A, and why

open-webui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Contents

What it installs

The manifest is a name and a version. 3 skills travel with it, and installing the plugin installs all of them — 474 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside marketplace.json#open-webui in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
