Rule Evaluation Policy

English | 한국어

The evaluation step evaluates the configured rules (Rule) and determines whether each label should be added, removed, or kept.

A condition (Condition) is evaluated and returns true/false.
- It checks whether the condition is satisfied and determines the result with the negate option.
A match (Match) is evaluated and returns pass/fail/skip.
- It determines whether to evaluate or skip the match with the skipIfBot option.
- It determines whether the match succeeds or fails from the condition evaluation results and the operator (any/all).
A rule (Rule) is evaluated and returns add/remove/keep.
- It determines the result from the match evaluation results and the removeUnmatchedLabels option.

Short-Circuit Evaluation

Within a match, conditions are short-circuited according to operator: any/all.
Within a rule, if one match passes, the remaining matches do not need to be evaluated.
