🧠 Agentic AI Pattern #1: ReAct (Reason + Act) Most LLM apps are one-shot: prompt in, answer out. ReAct agents are different. They think in a loop. Here's the cycle: → Thought: What do I know? What do I need? → Action: Call a tool, query a DB, run code → Observation: Here's what came back → Repeat until done Why does this matter for enterprise teams? Because real business tasks are never one-shot. "Summarise this contract and flag any clauses that deviate from our standard terms" requires reading, retrieving precedents, comparing, and reasoning — not a single inference. ReAct makes that possible by grounding each reasoning step in real data, not hallucinated recall. The risk to watch: loops. Without a hard step-limit or exit condition, a poorly prompted ReAct agent will spin. Always instrument max_iterations and log every thought/action/observation triple. This is pattern 1 of 8 in my series on agentic architectures enterprises are actually deploying. #AgenticAI #LLM #EnterpriseAI #ReAct

Sending every query to your most powerful model is like using a freight truck to deliver a letter. A router - or mixture-of-agents - pattern puts a lightweight classifier at the front door. It reads the request, decides which agent or model is the right fit, and dispatches. Simple FAQ to a small fast model. Complex multi-step reasoning to a large one. Legal queries to a specialist with retrieval. Code to a model fine-tuned for it. The user sees one entry point; behind it is a tiered fleet matched to task complexity. Use this for cost and latency optimisation, or to front a collection of narrow specialists without exposing their individual endpoints. The tradeoff: the router itself can be wrong. Misclassifications send hard queries to weak models or waste spend on trivial ones. Invest in routing accuracy before optimising the downstream fleet. In P1infinite, the pattern is a small Claude Haiku agent at the entry point - cheap, fast classification - feeding into a switch node that routes to specialist downstream agents, each with its own model, skills, and cost cap. Per-step model selection means the routing layer and the execution layers are composed naturally in the same DAG. Run telemetry shows which branch fired, what it cost, and how long it took - so you can tune routing rules against real traffic. #AgenticAI #LLM #EnterpriseAI #MixtureOfAgents

When many agents contribute to a shared artifact, direct message-passing gets tangled fast. The blackboard pattern replaces point-to-point coordination with a shared workspace. Agents read from it, write to it, and react to what others have written - without knowing who wrote it or when. Coordination emerges from the data, not from a central controller. This scales contributor count well: adding a new specialist agent means subscribing it to relevant state changes, not rewiring a call graph. Use it for evolving artifacts - a living design document, a simulation state, a report built by a dozen narrow agents over hours. The tradeoff is that control flow becomes implicit. If something goes wrong, tracing causality through a shared state store is harder than reading a linear execution log. You need good observability on the blackboard itself. In P1infinite, Atom memory is the blackboard. Typed, per-workspace shared state with a bus event on every write. Agents subscribe to atom-change topics using bus triggers and react autonomously when relevant state changes. The event bus is not a workaround - it is how the emergent coordination is wired. Every write is timestamped and attributed, so the audit trail on the shared state is built in. #AgenticAI #LLM #EnterpriseAI #BlackboardArchitecture

A single model pass on a hard reasoning problem gives you one perspective dressed up as certainty. Debate and ensemble patterns run multiple agents independently, often with different models or different system prompts, then merge or vote on the result. Independent generation means independent errors, so the aggregate is more robust than any single pass. Use this for high-stakes judgments, adversarial reasoning tasks, or anywhere you want to surface minority views before committing to an answer. A three-agent debate where two agents agree and one dissents is more informative than a single confident answer. The cost is real: N agents means roughly N times the token spend and latency. Do not reach for this on tasks that are cheap to verify by other means. In P1:infinite, a parallel node fans out to N agent branches simultaneously - each with its own model integration and system prompt. The aggregate node then merges or votes on the results. Critically, every branch records its full reasoning trace, so dissent is not lost in the merge. You can inspect the outlier argument in run telemetry and decide whether it was noise or signal. The debate is auditable, not just summarised. #AgenticAI #LLM #EnterpriseAI #EnsembleLearning #AiEducation

Some problems are too open-ended to plan. The right decomposition only becomes visible as you dig. Hierarchical - or recursive - decomposition lets agents spawn sub-agents that spawn their own, forming a task tree whose depth is discovered at runtime. A broad research task splits into subtopics; each subtopic splits into source queries; each query returns data that shapes the next level. You are not fixing the tree in advance - you are letting the structure emerge from the problem. This is the right pattern for large refactors, deep competitive research, or any task where the scope is genuinely unknown at the start. The cost is that it is hard to bound. Token usage and wall-clock time can compound exponentially if nothing stops the recursion. This is the architecture most likely to generate a surprise invoice. In P1infinite, loop nodes give you bounded recursion: explicit maxIterations and a per-step cost cap, enforced by the runtime, not by hoping the model stops. Sub-workflows can call other sub-workflows, so the hierarchy is real and composable. The brake is not an afterthought - it is a first-class field on the loop node. You get the open-ended power and the guardrail in the same primitive. #AgenticAI #LLM #EnterpriseAI #RecursiveAgents

One pass is rarely your best pass. The output that looks fine at generation often has silent errors a second look catches. Reflection - sometimes called self-critique - adds an evaluation loop. The agent produces output, scores or critiques it against defined criteria, then revises. It loops until the output passes or a maximum iteration count is hit. It is the LLM cousin of actor-critic: one network acts, another judges. Use it where quality matters more than latency - code you can run and test, writing with a clear rubric, structured data with a known schema. The cost is real: each revision round adds tokens and time. Without iteration bounds, costs compound fast. The tradeoff is simple: you are trading latency and spend for measurably better outputs. Do not reach for this on tasks where errors are not detectable on inspection. In P1:infinite, reflection ships as assertion rules on any step, no extra architecture required. The agent emits output; rules check it against JSON schema, regex patterns, or custom rubrics. On failure, the step retries automatically with the failure message injected as feedback. You set maxIterations and a cost cap on the loop node. The reflection primitive is configuration, not code you maintain. #AgenticAI #LLM #EnterpriseAI #SelfCritique #AiEducation

Most agent failures happen because the model tried to plan everything before touching a single tool. ReAct flips that. The agent reasons about what it knows, picks one tool call, observes the result, then reasons again. Each observation changes what happens next. It is not a plan executed blindly, it is a tight loop of think-act-observe that keeps adapting until the task is done or the agent decides it cannot proceed. This is the right default for most tool-using work: web research where you don't know what you'll find, debugging where the error message changes your next step, data pulls where one query shapes the next. The tradeoff is that you get less predictability and no auditable plan up front. If the task structure is known in advance, a planner-executor beats this. If it isn't, ReAct is your baseline. In P1:infinite, the agent step IS ReAct out of the box. Drop in your tools as typed Skills or MCP servers, set a tool-turn cap and a cost cap per call, and the multi-turn loop runs without any glue code. Every tool call, observation, and reasoning trace is recorded and replayable from run telemetry - so when it goes wrong, you see exactly why. #AgenticAI #LLM #EnterpriseAI #ReAct #AIEducation

Most teams are still talking about “agents” as if there is one architecture. There isn’t. An agent that researches the web should not be structured the same way as an agent that writes production code, governs a workflow, routes legal queries, or coordinates ten specialist workers over a shared artifact. Different problems need different agentic patterns. Over the next series, we’re breaking down the core architectural models behind production-grade agentic systems: → ReAct loops Reason, act, observe, repeat. Best when the path is unknown. → Plan-and-execute Create an auditable plan first, then execute step by step. Best when structure matters. → Reflection loops Generate, critique, revise. Best when quality matters more than latency. → Orchestrator-worker One coordinator, multiple specialists. Best when the work can be cleanly divided. → Hierarchical decomposition Agents spawn sub-agents recursively. Best for open-ended problems where the structure emerges as you dig. → Debate and ensemble Multiple agents reason independently, then merge or vote. Best for high-stakes judgment and surfacing dissent. → Blackboard pattern Agents coordinate through shared state, not direct messages. Best for evolving artifacts and long-running collaborative workflows. → Router / mixture-of-agents A lightweight classifier sends each query to the right model or specialist. Best for cost, latency, and domain routing. The point is not to make agent systems more complex. The point is to stop forcing every problem through the same architecture. In P1:infinite, these patterns become composable primitives: DAGs, sub-agents, loop nodes, switch nodes, shared Atom memory, assertions, telemetry, cost caps, and per-step model selection. The future of agentic AI is not one giant agent. It is the right architecture for the job.

The hidden cost of AI agents isn't the model. It's everything around it. Token costs get all the attention. But in most agentic deployments, the real expense is redundancy — agents re-fetching the same context, re-running the same logic, and re-solving problems that were already solved last week. Efficiency in agentic systems comes from architecture, not model selection. Three things that actually move the needle: → Reusable skills — capabilities are built once and shared across workflows. Every agent benefits. No duplication, less token spend. → Persistent memory (atoms) — context is stored and retrieved, not regenerated. An agent working a customer account pulls structured memory rather than re-processing raw data every time. → Efficient orchestration — lightweight agents handle lightweight tasks. Expensive reasoning is reserved for problems that actually need it. Nothing runs unnecessarily. This is how ProvenanceOne approaches agent economics. The goal isn't to run AI as cheaply as possible — it's to make sure every token spent is doing real work. When your agent infrastructure is designed well, cost stops scaling linearly with volume. That's the operational leverage that makes agentic companies structurally different from those still paying for brute-force AI. #AIAgents #CostEfficiency #AgentOps #EnterpriseAI #ProvenanceOne

5 hard-won lessons from shipping agentic workflows in production (not just in demos): 1. Bound the problem first Don't automate everything at once. Pick one workflow with clear inputs, outputs, and a measurable result. Content research → brief → draft is a perfect starting loop. 2. Design for failure before launch Agents will hallucinate, stall, or hit rate limits. Build retry logic, fallback states, and human escalation paths before go-live - not after your first incident. 3. One agent, one job The most common failure: one agent trying to research, write, edit, and publish. Narrow scope beats broad ambition. Keep handoffs explicit. 4. Instrument everything from day one Log every action, decision point, and tool call. You'll surface failure patterns in week one that would otherwise take months to find. 5. Expand autonomy incrementally Start with agents that recommend. Graduate to agents that execute. Trust is the real deployment constraint — earn it with consistent quality before removing humans from the loop. Agentic workflows are engineering problems, not magic. Treat them that way.
