Stop cascading failures in Go microservices.
A circuit breaker stops your Go service from hammering a failing dependency, preventing cascading failures that consume goroutines, sockets, and memory until the entire system collapses.
Process depth vs portability, not best tool.
Developers comparing Spec-Driven Development setups in 2026 are usually not asking which model is smartest. They are asking which workflow will keep an AI agent aligned without burying them in ceremony.
Five phases from intent to verified code.
Spec-Driven Development works when the specification is a workflow, not a document you file away after kickoff. The point is not to produce a large product requirements document.
Protocol security is who may act, not the model.
Prompt injection gets most of the security attention in LLM systems, and it deserves attention, but it is not the whole problem once agents start calling tools and delegating work to other agents.
Long-running A2A tasks outlive chat sessions.
Most AI agent demos still behave like chat completions with extra steps: you send a prompt, wait a few seconds, and get an answer back in one response.
40% of multi-agent pilots fail. Here's how to pick the right orchestration pattern - and avoid the ones that break.
Single-agent AI systems peaked in 2025 — you gave one LLM a prompt, some tools, and a goal, and it did reasonably well on bounded tasks.
Write the event with the data. Never split them.
Two writes that should succeed together will eventually fail separately.
Your order service saves the order to the database, then publishes an order.created event to a message broker.
Go context is control flow, not storage.
Go’s context.Context is simple enough to use badly — and that is the problem.
The spec as source of truth, not a side document.
Spec-Driven Development is one of those ideas that software engineers have reached for before and then set aside when the effort stopped paying.
Specs as source of truth, or slow ceremony?
Spec-Driven Development entered 2026 as the serious developer’s answer to vibe coding drift.
Keep intent close to the code.
Decision records are the missing memory layer in AI-assisted software development. They capture not just what was built, but why — and that distinction becomes critical when AI tools are writing your code.
Handle errors at the right boundary.
Go error handling is easy to complain about. Every Go developer has written this code hundreds of times:
Stop sleeping in concurrent Go tests.
Testing concurrent Go code has always required a bit of discipline. Goroutines are cheap, channels are simple, and context cancellation is idiomatic — background workers and timers are everywhere in real Go services.
A2A is not dead. It is just not universal.
Google’s Agent2Agent protocol, usually shortened to A2A, had a strange first year.
Reliable polling patterns for AI agents.
Polling agents are one of the least glamorous parts of AI assistant architecture, but they are also one of the most useful.
MCP gives agents tools. A2A gives agents peers.
AI agent architecture is starting to split into two layers.
