Hypothesis:
If we create community awareness about the ability to create and translate error messages on Wikifunctions, we will see an increase in the number of helpful error messages.

Acceptance Criteria

• [Engineering/Product] Community can add tests to assert that specific errors are correctly returned/etc.
• There is unified, findable documentation on function implementation that includes the usage of helpers such as WIkifunctions.Error()
• Tutorials/best practices
• Communications about this to support WF and WF-using communities

Goals & Success Metrics

• Evidence of helpful error messages created by the community
• There are new error types being created, translated and used by the community
• We gain learnings about editors’ usage of this feature to inform essential work
