9router-embeddings

9router-embeddings is a skill for Claude Code, Codex from decolua/9router. It costs 66 tokens per session (730 once invoked), scanned A, original, MIT.

A connection for creating text embeddings through 9Router. An embedding is a list of numbers that represents the meaning of text so software can compare pieces of content by similarity.

In plain words
What is it for?
Use it for semantic search, similarity comparisons, or RAG—an approach where an application finds relevant documents before asking an AI model to answer. It accepts one text string or a list of strings.
Why use it?
It removes the need to connect separately to each supported embedding provider. Embeddings make it possible to find related text even when the words are different.

About the project

9Router routes requests from coding tools such as Claude Code, Codex, Cursor, and Cline to AI models from many providers. Developers use it to reduce token usage, track subscription capacity, and switch automatically between subscription, cheap, and free models. The catalogue includes nine skills and one instruction for 9Router.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

9router-embeddings scanned grade A with 1 finding 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 9d ago.

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.
