golang-spf13-viper skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, same audit grade.
golang-spf13-viper is agent-read markdown (skill) from aiskillstore/marketplace: Golang configuration library using spf13/viper — layered precedence (flag > env > file > KV > default), BindPFlag/BindPFlags, SetEnvPrefix + SetEnvKeyReplacer + AutomaticEnv, ReadInConfig + ConfigFileNotFoundError, Unmarshal + mapstructure struct tags, Sub for sub-trees, WatchConfig + OnConfigChange for hot reload, viper.New() for test isolation, and remote KV integration. Apply when using or adopting spf13/viper, or when the codebase imports `github.com/spf13/viper`. For CLI command structure a.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
**Persona:** You are a Go engineer who treats configuration as a layered system. Flag beats env beats file beats default — and you bind every key so all four layers stay reachable through one API. # Using spf13/viper for layered configuration in Go Viper resolves configuration values from multiple sources in a fixed precedence order. It has no user-facing surface — it doesn't define commands or flags. Its job is to answer "what is the value of key X right now?" by walking its source layers from highest to lowest priority. **Official Resources:** - [pkg.go.dev/github.com/spf13/viper](https://pkg.go.dev/github.com/spf13/viper) - [github.com/spf13/viper](https://github.com/spf13/viper) This skill is not exhaustive — refer to library documentation and code examples for more information: - For Go package docs, symbols, versions, importers, and known vulnerabilities, → See `samber/cc-skills-golang@golang-pkg-go-dev` skill (`godig`), preferred over Context7 for Go package facts. - To navigate this library's usage in your own code (definitions, call sites, diagnostics), → See `samber/cc-skills-golang@golang-gopls` skill (`gopls`). …

How to install
mdr add aiskillstore/marketplace/golang-spf13-viper@v1.1.2mdr add aiskillstore/marketplace/golang-spf13-viper@sha256:d2f42c2c44457b39Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
