System design
System design, first.
The diagram can cause the code, not just describe it.

- What Is a Systems-Design-First Coding Agent?The architecture is the input, not the write-up.
- AI System Design Tools, ComparedThree different products share one search term.
- From System Design to CodeWhat has to be true for a drawing to become a build.
- Architecture-Aware Coding AgentsUnderstanding a system is not the same as reading a file.
- AI Software Architecture ToolsThree jobs, three very different reliabilities.
- A Coding Agent That Draws DiagramsOne model of the codebase, used twice.
Elsewhere
- System Design TemplatesEach template is a real diagram produced by the same layout engine the app runs, not a picture of one.
- Harness EngineeringAgent equals model plus harness. The harness is the half you can actually change.
- MCP and Architecture DiagramsYour agent supplies the structure. A constraint solver decides where everything goes.
- Generate a Diagram from Your CodeEvery source below lists the exact files it reads and the constructs it maps to diagram nodes.
- AI Diagram GeneratorsThe agent emits a semantic graph and ELK computes the layout, so overlapping boxes are structurally impossible.
- Compare Lucid TrainEvery page says what the other tool is better at. If that section were empty the comparison would not be worth reading.
- Convert Code and DiagramsEvery conversion page states what survives the round trip and what does not.
- Use CasesEach page includes who it is not for, which is usually the more useful half.
- Beyond DiagramsDiagrams are the front door. These are the rooms behind it.
