RAG Pipeline Utils v3.3: Grounding That Catches Negation, AI SDK Middleware, Test Matchers and Mastra

v3.3.0 makes the grounding check catch answers that contradict their source, and brings the checks to the tools you already use: middleware for the Vercel AI SDK, matchers for Jest and Vitest, and scorers and a guardrails processor for Mastra. Nothing breaks for existing code, but some answers that used to pass the grounding check now fail it, on purpose.

npm install @devilsdev/rag-pipeline-utils@^3.3.0

v3.2.0 splits the library into four packages you can install on their own, routes each query to the cheapest model that can answer it, records runs as OpenTelemetry spans, reports the time to first token, and runs on Cloudflare Workers and other edge runtimes. Installs are 15 MB smaller. Nothing changes for existing code.

RAG Pipeline Utils v3.0: Node 22, a Smaller Install and a Cleaner Main Entry

v3.0.0 is a clean-up release. It removes what 2.x deprecated, requires Node.js 22 and makes the OpenAI SDK an install you choose. The pipeline API, plugin contracts, .ragrc.json files and CLI commands don't change, so most projects upgrade by checking their Node version and, if they use OpenAI, running one extra install.

v2.7.1 is a small patch for the observability and error helpers. createError now gives every error code its own message, metrics no longer hand back the wrong kind of metric or lose error counts, and the event logger's constants cover every event it records. Nothing in the pipeline itself changes.

RAG Pipeline Utils v2.7: Evaluation in CI, pgvector and Qdrant, and Published Benchmarks

v2.7 is about knowing when your RAG pipeline gets worse before your users do. You can draft a test set from your own documents, score it from code or the command line, compare two configurations, and fail a pull request when answers get less grounded, with a new GitHub Action. It also adds retrievers for PostgreSQL with pgvector and for Qdrant, a generated API reference with corrected TypeScript types, and published, reproducible benchmarks.

v2.6.2 fixes one bug, and it's an important one: on a machine without husky installed globally, npm install @devilsdev/rag-pipeline-utils failed. That covers most laptops and every CI runner. Every release from 2.0.0 to 2.6.1 is affected. Please upgrade:

npm install @devilsdev/rag-pipeline-utils@latest
