Camunda FEEL Expressions

Write, debug, and evaluate FEEL expressions used in Camunda 8 BPMN processes, DMN decisions, and forms.

Prerequisites

• c8ctl CLI installed and configured (c8ctl add profile) — provides c8ctl feel evaluate
• Camunda 8.9+ cluster for default cluster-engine evaluation (uses POST /v2/expression/evaluation)

Cross-References

• camunda-bpmn: Use when FEEL expressions are part of BPMN conditions or I/O mappings
• camunda-dmn: Use when FEEL appears inside DMN — input expressions, input entries (unary tests), output entries, literal expressions
• camunda-forms: Use when FEEL expressions control form validation or conditional visibility
• camunda-ai-agents: Use when FEEL expressions are prompts, fromAi() parameter declarations, or toolCallResult shaping in an AI Agent process
