Can I use variables in Scorecard failure messages?

Using Dynamic Values in Failure Messages

Cortex supports mustache-style template variables in Scorecard failure messages. These allow you to display contextual information such as:

• The entity being evaluated

• Why a rule failed

• Dynamic links for remediation

Common Example

Service {{context.entity.name}} failed this rule.
View entity: {{context.entity.url}}

Using Captures in Failure Messages

If your CQL rule uses captures(), you can reference captured values in the failure message.

Example Rule

captures(key = "sli", value = custom("sli-value")) < 0.99

Example Failure Message

SLI is below threshold. Current value: {{context.evaluation.captures.sli}}

Note: Captured values must be part of the CQL expression to be available in the failure message.

Where to Find Full Documentation

Detailed usage and examples for captures() are documented in the CQL Explorer:
