Most RAG pipelines return useful results most of the time. The dispatcher in an agentic RAG system isn't just a router; it's the judgment call that decides when to loop back for another retrieval and when to trust what's already in context.

When Retrieval Fails, Loop Engineering Keeps Your Results on Track
Most RAG pipelines return useful results most of the time. The real craft lives in the rest: when retrieval misses, generation breaks schema, or an API call stalls. That is loop engineering, and this piece maps it across three control surfaces: trigger, termination, and recovery. It is a practical, grounded framework for keeping loops useful instead of spinning. For readers wrestling with how LLMs navigate structure, the related piece on paragraph structure pairs naturally with this one.
Designing the dispatcher that makes agentic RAG workflows smarter
The dispatcher in an agentic RAG system isn't just a router; it's the judgment call that decides when to loop back for another retrieval and when to trust what's already in context. This piece from our series on enterprise document intelligence finally puts the patterns together, and it's a refreshingly clear look at why that decision is the real engine of reliability. If you're still wrestling with when your workflow should stop, this is the guide you've been waiting for.
When Every Passage Holds the Answer, RAG Needs a New Shape
Most RAG pipelines retrieve a single top passage and call it a day. But some questions don't work that way. Listing questions demand every relevant passage, not just the highest-scoring one. This pipeline walks through that silent failure point and the pipeline shape that actually handles it. It's a practical look at a real limitation, and the reasoning is clear. For readers who want to go deeper, "Exploring Paragraph Structure: How LLMs Navigate Token Space" offers a useful follow-up on how token coordinates shape retrieval.
When your document says "see Section 7.2," AI can now follow the link.
A "see Section 7.2" answer is a dead end, not a destination. When a retrieval system points elsewhere instead of answering directly, the pipeline breaks trust. This piece tackles that exact failure with a loop-based fix: fetch the linked context, then return the real answer. It's a practical, human-centered solution for a frustrating problem. We appreciate the focus on user outcomes over technical spectacle. For more on how LLMs handle structure, explore *Exploring Paragraph Structure: How LLMs Navigate Token Space*.
Recover a PDF's hidden outline with typography and deterministic loops.
A PDF's outline is often hidden in plain sight, buried in the typography of its body text. Six deterministic signals on span-level formatting can surface heading candidates, with one bounded loop validating the real ones. It is a practical, grounded approach to document structure, and it earns its place in the RAG pipeline. For readers exploring how LLMs handle paragraph structure, our related guide on token space offers a useful complement.
Validate Your RAG Outputs with a Local-to-Flagship LLM Cascade
Twenty local models walked into a sweep against a hosted flagship, and the results point to a smarter way to build RAG. This piece from our latest volume breaks down a two-part cascade: one angle trims cost, the other tightens validation, together forming a loop that feels refreshingly practical. It's not about discarding what works; it's about layering intelligence where it matters. For those ready to move beyond static pipelines, this is a thoughtful, actionable read.
Smarter RAG Generation: Choosing the Right Candidates for Every Query
Retrieving top-k candidates is only half the battle; the real question is how you feed them to the generator. This piece tackles that head-on, detailing two regimes for sending retrieved chunks and the sufficiency signal that tells you which to use. It's a practical, per-question dispatch that keeps things cheap and efficient. We appreciate the focus on iteration over brute force.
When spreadsheets fail, adaptive parsing hands your data to the right expert
When a flat table or a figure slips past your parsing pipeline, the LLM becomes the last line of defense. That is the premise of this walkthrough, and it is a good one. We follow two real escalations end to end: one flat table routed to Azure, one figure handed to a vision model. The approach is practical, not theoretical. If you are exploring how to build resilient document intelligence, this is worth your time.
Before retrieval begins, a small loop refines your question
The small loop runs before retrieval, and that sequencing is the insight. Read the doc, ask what is missing, re-parse. It is a tight, deliberate cycle that treats question parsing as its own engineering problem, not a footnote to context building. We appreciate the restraint here. This is prompt engineering, then context engineering, then loop engineering, each step earning its place. For readers tracking how LLMs navigate structure, our related piece on paragraph structure in token space pairs well with this disciplined approach.
Smart Parsing That Escalates Only When the Data Demands It
Most PDF parsing bills you for every page, whether you need it or not. This piece from our series on enterprise document intelligence flips that model. It walks through an escalation cascade where cheap, deterministic checks run first, flagging a failed parse before you ever pay for a heavier parser. That pragmatic, cost-aware loop is exactly the kind of engineering discipline we admire. If you enjoy this, our related piece on bridging retrieval and action offers a similarly grounded take on connecting AI tasks.
When the Loop Has No Brain, the Architecture Speaks for Itself
Most discussions of loop engineering assume an LLM sits at the center of the loop. This experiment challenges that by removing the model entirely, using a deterministic, zero-dependency Python benchmark to isolate the architecture itself. The author tested whether a goal-directed controller could isolate failures better than a linear pipeline, validating it across 300 random seeds. The results are narrow but compelling: failure isolation is a measurable property of control flow, independent of reasoning.
