AI Agent Tool Approval Gates for Destructive Operations
Agents with tools that mutate external systems require policy checks before executing high-impact actions. Begin with the exact user problem and the guarantees...
RAG Evaluation With Answer Relevance and Context Recall Metrics
Answer relevance and context recall measure different aspects of a retrieval-augmented generation system. Begin with the exact user problem and the guarantees...
AI Agent Idempotency Keys for External Tool Actions
Agent actions with external side effects need stable operation identifiers and duplicate-safe server behavior. Begin with requirements and the workload. Record...
RAG Hybrid Search Ranking With Metadata Filters
Hybrid retrieval combines semantic and lexical signals, while metadata filters enforce eligibility and narrow search. Begin with requirements and the workload....
RAG Document Freshness Strategies for Frequently Updated Knowledge Bases
Retrieval can cite stale documents even when the original knowledge base has changed; updates and deletions must propagate through indexing. A production...
Designing Tool Schemas for LLM Function Calling That Models Use Correctly
Quick answer: models choose and fill in tools based on the names, descriptions, and parameter schemas you provide, so treat those as the interface design. Use...
Reducing Hallucinations With Grounding, Citations, and Abstention Patterns
Quick answer: you cannot eliminate hallucinations, but you can reduce and contain them. Ground answers in retrieved sources, instruct the model to use only...
Latency Optimization for LLM Applications: Streaming, Parallel Calls, and Smaller Models
Quick answer: LLM latency comes mostly from processing the prompt and then generating output tokens one by one. Cut it by shortening prompts and outputs,...
