camunda-feel

Use this skill to write, debug, evaluate, and validate FEEL (Friendly Enough Expression Language) expressions for Camunda 8 — the expression language Zeebe uses in BPMN, DMN, and Camunda Forms. Use for: gateway conditions and conditional sequence flows; service-task input/output mappings; timer durations and cycles (ISO 8601 PT.../R...); DMN input/output entries; Camunda Form validation rules and conditional visibility; connector result and error expressions; list filters, projections, and quantifiers; date and duration arithmetic; type coercion (number-to-string); null-safe access; debugging FEEL_RESOLUTION_ERROR or "Can't add 'N' to ..." warnings. Do not use for: writing the BPMN XML around expressions (use camunda-bpmn) or designing form structure (use camunda-forms). **Utility skill** — FEEL is reused inside BPMN, DMN, forms, and connector configuration. Covers c8ctl feel evaluate for validating expressions.
