To validate PlantUML sequence diagrams, apply 2-space indentation rules, use colored group syntax, and ensure one return message for every arrow message. This enforces strict structural conventions for files ending in -seq.puml.

The standard format for PlantUML sequence diagrams requires 2-space indentation, colored group syntax, and exactly one return message for every arrow message. These conventions prevent inconsistencies and improve diagram readability.

No, PlantUML sequence diagram validation does not work for activity, swimlane, or state transition diagrams. The validation explicitly rejects non-sequence diagram types and applies exclusively to files ending in -seq.puml.

Your PlantUML sequence diagram fails formatting checks if it lacks 2-space indentation, misses colored group syntax, or has an arrow message without a corresponding return message. Validation enforces these strict structural conventions.

To validate a -seq.puml file against code standards, apply checks for 2-space indentation, colored group syntax, and the one return message per arrow message rule. This ensures the sequence diagram meets established quality guidelines.
