Topic Pillar
Multi-Agent Systems.Supervisors, handoffs, swarms — and when each one breaks.
One agent works. Two agents talk. Five agents argue forever unless the orchestration is right. Multi-agent systems are not "more agents" — they are an architecture decision about who decides what, when, and with what budget. The orchestration pattern matters more than the model choice.

Supervisor vs handoffs
Supervisor pattern: one orchestrator delegates to specialists and integrates their answers. Clean on paper, slow in production when the supervisor becomes a bottleneck. Handoffs: agents pass the baton with the current context. Messier in code, recovers better when one agent loses the plot. Most teams that start with supervisor end up on handoffs for the recovery story.
When to reach for a swarm
Swarms shine when sub-goals are genuinely parallelisable and the work is exploratory — research, broad search, multi-source synthesis. Skip swarms for sequential workflows; the coordination overhead destroys the parallel-win on anything that has to happen in order.
Parallel sub-agent execution in practice
Modern agent runtimes can fan out to sub-agents for independent reads, then serialise on the write turn. This cuts a 20-minute refactor to under 4. The orchestration pattern matches the supervisor / swarm split — supervisor for the plan, swarm for the read phase, supervisor again for the write.

Agentic RAG vs vanilla RAG: why a Sufficient Context Agent beats retrieve-then-pray
Google Research shipped Agentic RAG on Gemini Enterprise with a Sufficient Context Agent that refuses to answer when retrieval is incomplete. On factuality benchmarks they report up to 34% higher accuracy versus standard RAG. Here is when one-shot RAG is still enough, when you need iterative retrieval, and how I wire the pattern without blowing latency budgets.

Read the post Multi-AgentInside Recruiting Atelier: a runnable reference for the primitives of an agentic system
A working open studio that vets duplicates, plans the run, screens, scores, shortlists, and notifies. The whole pipeline lives in roughly ninety lines of supervisor code and a tool registry you can read in one sitting. Here is what is inside, why every piece is there, and what you can copy into your own stack.

Read the post ArchitectureAI agent vs agentic AI: what the distinction actually means when you ship one
Vendors blur the line because "agentic" sells. The two terms describe different architectures, with different cost shapes, different observability needs, and different scoping conversations. Here is the framing I use with clients and the three-question test for which one your project actually needs.

Read the post Multi-AgentWhy I am replacing supervisor patterns with handoffs
Supervisors looked clean on paper and shipped slow in production. Handoffs read messier in the code but recover better when an agent loses the plot. Two real systems and where supervisors still earn their keep.

Read the post ArchitectureThree patterns I broke in 2025, and what I do instead now
Self-correction loops without budgets, single-agent solutions to multi-domain problems, and using JSON mode to force structure I should have built into the schema. An honest review.

Replacing Sonnet with Haiku in the dispatcher role cut our orchestration cost dramatically. It also cost us in two specific places I did not predict.
