GitHub Just Put Agents in CI. Your Bottleneck Is Now Governance
Software delivery is becoming continuous inference. Agents don't just suggest code anymore. They act inside the delivery plane. And the first thing that breaks…
Reranking and the Recall You Throw Away
You added a reranker because retrieval quality was not good enough. The relevant passage kept landing at rank eight when it should have been…
Chunking Is Where RAG Silently Fails
You have tuned everything. A better embedding model, a reranker, hybrid search. Retrieval quality is still not what it should be, and you cannot…
Building Production-Ready LangChain Agents: Architectural Patterns That Work
Turning architectural gaps into engineering patterns The Gap Between Demo and Production Last week I evaluated LangChain's architecture using SRAL. The scorecard revealed something…
Research Vault: Open Source Agentic AI Research Assistant
The Problem Nobody Talks About I was drowning in research papers. Not metaphorically—I had 50+ PDFs, dozens of articles, and a note-taking system that…
Applying SRAL to LangChain: An Architectural Evaluation
A systematic evaluation of LangChain's architectural foundations using the SRAL framework Scorecard Summary Component Score Key Finding State ⚠️ Weak-to-Moderate Memory is optional, not…
Tools Don’t Extend an Agent. They Define It.
A 6.7-billion-parameter model, given a handful of tools, beat a model 26 times its size on a range of zero-shot tasks, from factual lookups…
SRAL Framework: The Four Questions I Ask About Every AI Agent
The Problem With Agent Evaluation Most conversations about AI agents focus on capabilities. Can it browse the web? Can it write code? Can it…
PART II — ReAct: The Architecture That Unified Agentic Reasoning
Most discussions of ReAct frame it as a clever prompting technique. It isn’t. ReAct is the first time we gave language models a structure…
