To generate a Mermaid class diagram, provide your BDD collaborator and relation sets to produce a boundary-aware `.class.mmd` file. The diagram contains only supported dialect elements like class declarations, allowed link glyphs, and notes for consistent downstream documentation.

Boundary-aware class diagram generation in BDD planning converts reasoning packages into Mermaid class diagrams that enforce consistent structural boundaries. This ensures downstream work relies on a validated diagram artifact rather than guessing collaborator relationships and limits.

You validate Mermaid syntax by running the `scripts/evaluate.py` evaluator immediately after writing the `.class.mmd` file. It checks the output against a strict Mermaid subset and returns a clear JSON pass/fail validation report.

The Mermaid class diagram generator does not support all syntax elements; it uses a strict Mermaid subset for deterministic rendering. It only produces allowed class declarations, link glyphs, and notes to ensure validation passes and boundary consistency.

Your generated Mermaid class diagram fails syntax validation when it includes elements outside the strict Mermaid subset evaluated by `scripts/evaluate.py`. The Skill returns an error-first validation report indicating which boundary-aware constraints were violated.

You can use this Mermaid diagram generator without a full BDD pipeline, but it is optimized for BDD-oriented planning and documentation workflows. It requires caller-provided collaborators and relationships to output a deterministic, boundary-aware `.class.mmd` artifact.
