Poem

A hop, a lint, a tidy mod file,
Hello, world! I print with a smile.
Unused carrots? I’ll vet that stash—
gofmt whiskers, a tidy cache.
With paths all filtered, I thump in cheer—
Ship it swift, the code is clear! 🥕✨

Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	You can run @coderabbitai generate docstrings to improve docstring coverage.
Title Check	❓ Inconclusive	The title “Preview/go” is overly generic and does not clearly convey that the pull request adds a basic Go module, a sample main.go file, and related lint configurations; a descriptive title that summarizes the primary change would help reviewers understand the intent at a glance.	Please revise the title to clearly summarize the main change, for example “Add Go sample module with main.go and lint configurations,” so reviewers can immediately grasp the purpose of the PR.

⚠️ Potential issue | 🔴 Critical

Remove unused variable to keep go build passing.

Go rejects unused locals, so leaving unusedVar in place breaks compilation. Please drop the declaration (or use _) so the project builds cleanly.

 func main() {
-	var unusedVar int
 	fmt.Println("Hello, world!")
 }

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	var unusedVar int
	fmt.Println("Hello, world!")
	func main() {
	fmt.Println("Hello, world!")
	}

🤖 Prompt for AI Agents

In main.go around lines 8 to 9, there is an unused local variable declaration
"var unusedVar int" which causes Go build failures; remove this unused
declaration (or if the value is needed later, assign it to the blank identifier
`_` or use the variable) so the file compiles cleanly and keep only the
fmt.Println call.
