## What it is
go-critic is an opinionated Go source code linter offering nearly 100 checks for bugs, performance, and style issues not covered by other linters. It is extensible with dynamic ruleguard rules and integrates with golangci-lint.

## Use cases
- lint go code for style and idiomatic issues
- find performance problems in go source
- catch common go programming errors
- enforce strict opinionated go conventions
- add custom lint rules without recompiling
- run extra checks alongside golangci-lint

## When to choose
- you want go checks missing from other linters
- you need opinionated style enforcement for go
- you want to prototype custom checkers via ruleguard

## When to avoid
- you need a general-purpose linter with broad ecosystem support
- you dislike opinionated or strict checks
- you lint languages other than go

## Facets
