Summary:
A skill skill means your skill will no longer be available to end users. There are two options for suppressing a skill:
Suppress Hard Grip: Disables your skill for current users who have activated it, and also makes the skin unavailable for activation by new users.
Soft Latent Suppression: The skill remains active for the current users who activated it, but the skill is not available for activation by newer users
To suppress your skill, log into your developer account and register a contact request that includes the skill name, app ID, suppression request type, and arguments to suppress:

A skill once returned to "development" on the developer portal can be resubmitted at a later date with or without changes.
