Pattern Catalog Summary: An Interactive Navigator for 56 Agentic Patterns

This is the single-screen index to the whole catalog: 56 agentic architectural patterns in one searchable navigator. Filter by pattern type or by Agentic AI maturity level (1–6), switch between grouped and flat views, and open any pattern for its summary, when-to-use guidance, and maturity placement. It’s the fastest way to find the pattern that fits the problem in front of you.

On the count (55 vs 56). The book and its companion reference catalog and skills package present 55 patterns across seven chapters. This navigator adds one consolidated entry — Advanced Model Tuning Patterns (SFT, PEFT/LoRA, DPO), grouped under Advanced Adaptation & Self-Improvement — bringing the interactive total to 56. The extra entry is a superset, not a discrepancy: everything in the 55-pattern catalog is here, plus model tuning.

How the catalog is organised

The 56 patterns sort along two axes. The type axis groups them into seven concerns; the maturity axis places each on a 1–6 ladder of agentic sophistication — and many patterns span more than one level, appearing in a simpler and a more advanced form.

#Pattern typePatterns
1Agent-Level Capability5
2Multi-Agent Coordination & Topology14
3Explainability, Compliance & Governance4
4Robustness & Fault Tolerance16
5Human-Agent Interaction5
6System-Level Infrastructure4
7Advanced Adaptation & Self-Improvement8

As in the rest of this series, Robustness & Fault Tolerance is the largest category (16) — the recurring signal that the hard engineering in multi-agent systems is what happens when things fail, not when they succeed.

The maturity ladder

  • Level 1 — Basic Agentic Systems: single-agent tool execution via fixed workflows and direct function calls.
  • Level 2 — Dynamic Single-Agent Workflows: dynamic tool selection, basic state, and RAG grounding.
  • Level 3 — Introspective: step-by-step reasoning, self-reflection, retries, and prompt mutation.
  • Level 4 — Multi-Agent Systems: collaborating specialists, top-down orchestration, governance and auditability.
  • Level 5 — Advanced Coordination: meta-agents, market topologies, sandboxing, bidding and consensus.
  • Level 6 — Self-Correcting Ecosystems: decentralized consensus, negotiation, coevolved training and emergent adaptation.

For the fuller treatments, this catalog connects to the rest of the series: the 55-pattern reference catalog (full context / problem / solution / code), the installable Claude Agent Skills, and the Skills Portal & Simulator for copy-paste system-prompt contracts.

Agentic AI Blueprint — a seven-level enterprise maturity roadmap from data foundation to multi-agent systems.

The Agentic AI Blueprint: From Thinking to Acting

Most enterprises do not fail at agentic AI because they picked the wrong model. They fail because they attempt Level 6 on a Level 0 foundation — building multi-agent orchestration on top of data nobody has cleaned, governed, or licensed. This blueprint lays out the sequence: a seven-stage maturity roadmap from data foundation to multi-agent ecosystems, the internal anatomy of an agent, and the use cases that pay for the work.

↗ Open the blueprint full-screen  ā€”  the maturity levels and the agent loop are both interactive.

The maturity roadmap: why the order matters

The seven levels run Data Foundation → Model Selection & Serving → Contextual Enhancement (RAG) → Tuning for Specificity → Grounding & Evaluation → Single-Agent Systems → Multi-Agent Systems. Click any level in the blueprint for its definition and a worked enterprise example.

The ordering is not decorative — it is a dependency chain, and each level exists to make the next one survivable:

  • Levels 0–2 establish what the system can know. Governed data, a served model, and retrieval that grounds it in your reality rather than the open internet.
  • Levels 3–4 establish whether you can trust it. Tuning adapts the model to your domain; grounding and evaluation make its answers traceable to a source and measurable against accuracy, fairness, and safety. This is the level most often skipped, and skipping it is why pilots stall before production.
  • Levels 5–6 establish what it can do. Only once knowledge and trust are in place does autonomy become responsible — first a single agent running its own loop, then multiple agents coordinating and negotiating over A2A.

Read the chain backwards and the common failure mode is obvious: an organisation that jumps to Level 6 inherits every unresolved problem from Levels 0 through 4, now multiplied across a fleet of agents that act on it autonomously.

The anatomy: Sense → Reason → Plan → Act

The middle section opens up the loop that defines an agent, wrapped around a persistent core of goals and memory. Tap or hover each stage for its role and the standard that mediates it:

  • Sense — gathering environment state from APIs, databases, and sensors; increasingly standardised through MCP so models can reach data feeds uniformly.
  • Reason — the LLM core interpreting the relationship between goal, perception, and available actions.
  • Plan — decomposing a high-level objective into executable sub-tasks.
  • Act — executing against the environment via function calling, where the model selects a tool schema and its parameters.

What makes this a genuine loop rather than a pipeline is that acting changes the environment the agent will next sense. That feedback is the source of both an agent’s adaptability and its capacity to compound an early mistake — which is precisely why the trust levels come first.

Where it pays

The application explorer splits use cases into horizontal (functions common to every business — customer service, IT, supply chain, finance) and vertical (domain-specific — healthcare, finance, retail, manufacturing). The distinction is a sequencing decision, not a taxonomy exercise: horizontal use cases like autonomous escalation or automated debugging tend to be the cheaper first win because the domain knowledge required is shallower, while vertical cases like drug discovery or loan underwriting carry higher value and a much steeper grounding and compliance burden.

One note on framing: the maturity model here is the enterprise GenAI adoption ladder — how an organisation gets from raw data to a multi-agent ecosystem. It is a different lens from the Agentic Governance Maturity model, which asks how much control machinery sits around the stochastic core. This blueprint answers “what should we build next”; that one answers “what must we contain before we can trust it.” For the pattern-level detail underneath both, see the 55-pattern catalog.
