go-build

Go Build and Fix

This command invokes the go-build-resolver agent to incrementally fix Go build errors with minimal changes.

What This Command Does

1. Run Diagnostics: Execute go build, go vet, staticcheck
2. Parse Errors: Group by file and sort by severity
3. Fix Incrementally: One error at a time
4. Verify Each Fix: Re-run build after each change
5. Report Summary: Show what was fixed and what remains

When to Use

Use /go-build when:

• go build ./... fails with errors
• go vet ./... reports issues
• golangci-lint run shows warnings
• Module dependencies are broken
• After pulling changes that break the build

Diagnostic Commands Run

# Primary build check
go build ./...

# Static analysis
go vet ./...

# Extended linting (if available)
staticcheck ./...
golangci-lint run

# Module issues
go mod verify
go mod tidy -v

## Initial Diagnostics

```bash
$ go build ./...
internal/service/user.go:25:15: undefined: UserRepository
internal/handler/api.go:42:9: cannot use x (type string) as type int
internal/handler/api.go:58:2: missing return at end of function

Errors found: 3

Fix 1: Undefined Identifier

File: internal/service/user.go:25 Error: undefined: UserRepository Cause: Missing import

// Added import
import "project/internal/repository"

// Changed
var repo UserRepository
// To
var repo repository.UserRepository

$ go build ./...
# 2 errors remaining

Fix 2: Type Mismatch

File: internal/handler/api.go:42 Error: cannot use x (type string) as type int

// Changed
count := params.Get("count")
// To
countStr := params.Get("count")
count, _ := strconv.Atoi(countStr)

$ go build ./...
# 1 error remaining

Fix 3: Missing Return

File: internal/handler/api.go:58 Error: missing return at end of function

func GetUser(id string) (*User, error) {
    if id == "" {
        return nil, ErrInvalidID
    }
    user := findUser(id)
    // Added missing return
    return user, nil
}
