## What it is
GoWrap is a command line tool that generates decorator implementations for Go interface types using templates. It lets developers quickly add cross-cutting concerns like metrics, tracing, fallbacks, and circuit breaking to existing interfaces.

## Use cases
- generate prometheus metrics decorators for go interfaces
- add tracing wrappers to existing go code
- generate fallback decorators for go interfaces
- wrap go interfaces with circuit breaker logic
- generate interface implementations from templates
- add logging decorators to go interfaces

## When to choose
- you maintain Go codebases and want to add metrics, tracing, or fallbacks to interfaces without hand-writing boilerplate
- you want template-driven, repeatable code generation integrated with go:generate

## When to avoid
- you work outside the Go language
- you need runtime (not compile-time) dynamic proxying or reflection-based wrapping

## Facets
- artifact type: cli-tool
- maturity: active
- function: developer-tools, cli, monitoring, logging
- domain: developer-tools, backend, programming-languages
- platform: go, cli, cross-platform
- tags: go, decorators, interface-wrapping, code-generation, prometheus, tracing, fallback, templates, command-line
