Description
golang-spf13-viper is an agent skill for configuration in Go with the spf13/viper library. Viper reads values from several sources and resolves them in a fixed order of precedence: a command-line flag beats an environment variable, which beats a configuration file, which beats a key-value store, which beats a default. The skill teaches the agent to bind every key so that all of these layers stay reachable through one API. It covers binding flags with BindPFlag and BindPFlags, setting an environment prefix with SetEnvPrefix, and mapping key names to environment variable names with SetEnvKeyReplacer. Viper has no user-facing surface of its own, since it defines no commands or flags. Its job is to answer the question of what the value of a given key is right now, by walking the source layers from highest to lowest priority. Command-line parsing is handled by the cobra library, which has its own skill. The skill points to the official Viper documentation for anything it does not cover, and it is part of the samber cc-skills-golang collection. It is added to a compatible agent with the skills command, and it is useful for Go services and tools that need one configuration model.…
