%description
A model-agnostic safety layer for developers building with large language
model (LLM) applications. Maps starter controls to the Open Worldwide
Application Security Project Top 10 for Large Language Model Applications
2025 risk categories <https://genai.owasp.org/llm-top-10/> via a modular
rule engine. Supports regular-expression rules, lightweight natural
language processing (NLP) intent checks, optional scanners, and semantic
large language model reviewer checks on prompts, conversations, retrieved
context, tool inputs and outputs, streaming chunks, and model outputs.
Supports workflows with the 'Ollama' local web service
<https://ollama.com/> via 'ellmer', remote reviewer endpoints, and other
chat interfaces callable from 'R'. Intended as an experimental guardrail
layer that teams should evaluate against their own workflows before
relying on it in production.
