6 terms starting with "R"
ReAct Pattern
A prompting pattern where the model alternates between reasoning ("Thought"), acting ("Action" = tool call), and observing ("Observation" = tool result), looping until a final answer.
SecurityRed Teaming
Adversarial testing of an LLM system -- deliberately trying to break it -- to surface safety failures, injection vectors, and misuse paths before real users (or attackers) find them.
AgenticReflection (Self-Critique)
A pattern where the model reviews its own output against the task, identifies flaws, and produces an improved revision -- in the same prompt or a follow-up call.
AppliedReranker
A model that takes a candidate list of retrieved documents and a query, and produces a more accurate ranking -- applied after initial retrieval (BM25, vector, or hybrid) as a second pass.
AppliedRetrieval-Augmented Generation (RAG)
A pattern where relevant context is retrieved from a knowledge base (vector store, search index, graph) and injected into the prompt before the model generates its answer.
TechniquesRole Prompting
Assigning the model a concrete professional role (e.g. "senior security engineer", "copy editor") to shape its framing, vocabulary, and priorities -- distinct from broader persona prompting.
