Your SEO Traffic Dropped and You Didn't Change a Thing. Here's Why — and the Fix.
Google AI Overviews now appear on 52% of all searches and answer the question before anyone clicks. If your organic traffic fell 20–60% in the last year and your rankings didn't change, this is why — and here's exactly what to do about it.

AI Agents for Business in 2026: What They Are, What They Cost, and How to Build the Right One
Gartner projects 40% of SMBs will deploy at least one AI agent by end of 2026. Most won't know the difference between an agent and a chatbot until they've paid for the wrong one. Here's the complete breakdown: what agents actually do, what each type costs, and how to build one that earns its keep.

MCP in Production: The Four Boundaries a Deployment Has to Get Right
Most MCP failures are not bugs in a server. They are decisions made at the wrong boundary — authorization enforced where it cannot see identity, integrity checked where it cannot detect change, state assumed where the protocol guarantees none.

RAG in Production: Four Stages, Four Ceilings, and How to Tell Which One Failed
A RAG pipeline has four stages, and each one sets a hard ceiling on everything downstream. That is why an end-to-end quality score tells you a system is bad without telling you which part is — and why most RAG tuning is guesswork with a good vocabulary.

PostgreSQL Performance Tuning in 2026: Indexes, N+1 Queries, and What Actually Helps
March 25, 2026
Slow PostgreSQL queries almost always come down to three root causes: missing indexes, ORM-generated N+1 queries, or a misread query planner. Here is how to diagnose and fix each one — with real EXPLAIN ANALYZE output and composite index patterns for multi-tenant apps.

Your Recursion Limit Is Not a Budget: Why AI Agent Costs Explode in Production
August 7, 2026
Every agent framework ships a step limit. None of them ships a budget. Because context grows on every turn, a fixed step cap can cost $0.50 or $500 — and the gap between those two numbers is where production bills go wrong.

MCP's Second Hop: Why You Cannot Pass the Client's Token to an Upstream API
August 7, 2026
Your MCP server has a validated token from the client. It needs to call GitHub on the user's behalf. The obvious move — forward the token — is explicitly forbidden by the specification, and the specification does not define a replacement. Here is what actually works.

When an MCP Gateway Earns Its Place — And Why It Has Nothing To Do With Server Count
August 7, 2026
The advice circulating is that you need an MCP gateway once you are running more than three servers. That number is wrong because it measures the wrong thing. The threshold is statefulness, and you can cross it with a single server.

MCP Tool Poisoning: Approving a Tool Once Is Not Enough
August 7, 2026
Tool descriptions are instructions to your model, and MCP lets a server change them after approval. The recommended defence is to pin them by hash. The disclosure that named that defence did not say what to hash, and hashing the obvious field leaves the attack open.

Your RAG Problem Is Recall, and You Are Fixing Precision
August 8, 2026
When retrieval is bad, teams add a reranker. It is the wrong fix for the most common failure, and it is structurally incapable of helping: reordering a candidate set cannot introduce a document that was never in it. Here is how to tell the two failures apart.

What Structured Outputs Actually Guarantee — And Three Ways You Get Nothing
August 8, 2026
Structured outputs are described as guaranteeing that a model returns valid JSON matching your schema. That is true with three exceptions your code must handle, and the schema language is a restricted subset that quietly reshapes how you model optional fields.

pgvector or a Dedicated Vector Database? It Is a Memory Arithmetic Problem
August 8, 2026
Vector database comparisons are written as feature tables. The decision is almost never made on features — it is made on whether the index fits in memory you are willing to pay for, and that is arithmetic you can do before choosing anything.

Prompt Caching Done Wrong Costs 25% More Than Not Caching At All
August 8, 2026
Prompt caching is usually presented as a free optimisation you either get or do not. It is not free. Writes cost more than uncached tokens, so a misplaced breakpoint means paying a permanent 25% premium for a cache nothing ever reads.

LangGraph Replays Your Nodes — Which Means Your Side Effects Happen Twice
August 8, 2026
Durable execution is sold as crash recovery, and it is. The part that gets skipped is what recovery does: nodes after the checkpoint re-execute, including the ones that charge cards and send email. Durability is not exactly-once, and the difference is your problem.

A 200 Does Not Mean It Worked: LLM Streaming Failures in Production
August 8, 2026
A streaming response is a sequence of events, not a request that either succeeds or fails. It can open cleanly, deliver half an answer, and then send an error — and the four failure modes that follow from that all produce code which looks correct and is not.
