The Agentic System Design Map
Building a production-grade AI agent is not a single structural decision—it is a sequence of 34 distinct architectural choices. Use this interactive blueprint board to map out your architecture options and run instant compliance audits.
How to actually run this
Don't work the board top to bottom in a single sitting. Work it by leverage. Settle Tier 1 before you write a line of code — these are business and risk decisions as much as technical ones, and they belong on a whiteboard with the people who'll own the outcome. Getting "does this even need an agent" and "how much autonomy, over what" right is worth more than every downstream optimization combined.
Tiers 2 and 3 are the engineering core — made once, deliberately, after Tier 1 is locked. Resist the pull to start here because it's the fun part; tools and models chosen before the framing is settled are the integrations you'll later throw away. Treat Tier 4 as a design input, not a checklist: evaluation, observability, and human-in-the-loop controls decided after launch are the ones that never get retrofitted properly. And Tier 5 is where adoption lives or dies — a technically perfect agent nobody trusts enough to use is a failed project, no matter how clean the architecture.
The field's failures cluster in predictable places, and every one is an early-tier decision made late:
- Building an agent where a workflow would do.
- Adding agents and tools without paying the failure-surface tax.
- Choosing for demo velocity and inheriting a production control ceiling.
- Treating evaluation and change-management as afterthoughts.
The map's job is to drag those decisions forward, where they're cheap, instead of leaving them to surface in production, where they're not. Each spoke in this series takes one cluster and turns its choice-list into a full decision guide with a verdict.
An agent engineer's real job is judgment about where not to let the model decide. Every row on this board is a place that judgment gets exercised; the choices are what you're choosing between. Master the early tiers and the rest narrows to a few sensible options. Skip them and you rebuild. If you internalize one thing from the whole map: the highest-leverage decision in the set is autonomy-and-reversibility — for any given action, how much independence the agent gets and whether that action can be undone. Nearly every expensive agent failure traces back to getting that one wrong.
