Mission

Write and maintain FPL expressions and scripts used by logiCells models while staying within public Runtime boundaries.

Key skills

• values, variables, and conversions;
• functions, lambdas, and composition;
• control flow;
• collections and context access;
• actions and events;
• evaluation-error diagnostics;
• choosing the right boundary between script, model action, and SDK code.

Principle

Scripts should express logic local to the model or interaction. Complex orchestration, external integration, or infrastructure policy belongs in the appropriate layer.

The exact grammar is versioned: reference examples should be validated against the target Runtime.
