+name: scripting-with-go
+description: Creates executable Go scripts with shebang-like behavior.  Use when the user wants Go scripts, mentions Go scripting, or needs executable .go files. If working in a Go project, do NOT use unless explicitly requested.

+
+Create executable Go scripts using a shell trick (not a true shebang). Scripts run directly like `./script.go` with full argument support.
+
+## Basic pattern
+
+First line of any Go script:
+
+```go
+/**/usr/local/go/bin/go run "$0" "$@"; exit;
+```
+
+Then `chmod +x script.go` and run `./script.go args`.
+
+## How it works
+
+1. OS tries to execute `./script.go` as binary
+2. Fails with ENOEXEC (not a binary)
+3. OS falls back to `/bin/sh`
+4. Shell runs first line: compiles and executes the script
+5. `$0` = script path, `$@` = all arguments
+6. `exit;` prevents shell from interpreting remaining Go code
+7. `/**/` instead of `//` avoids gopls formatting complaints
+
+## Complete example
+
+```go
+/**/usr/local/go/bin/go run "$0" "$@"; exit;
+package main
+
+import (
+	"fmt"
+	"os"
+)
+
+func main() {
+	if len(os.Args) < 2 {
+		fmt.Println("Usage: ./script.go <name>")
+		os.Exit(1)
+	}
+	fmt.Printf("Hello, %s!\n", os.Args[1])
+}
+```
+
+## When to use
+
+**Good for:**
+- Long-lived automation needing stability (Go 1.x compatibility guarantee)
+- Cross-platform scripts
+- Corporate environments
+- Scripts that may grow into programs
+- Avoiding dependency management hell
+
+**Avoid for:**
+- Simple one-liners
+- Systems without Go
+- Throwaway scripts
+
+## Common patterns
+
+### CLI flags
+
+```go
+/**/usr/local/go/bin/go run "$0" "$@"; exit;
+package main
+
+import (
+	"flag"
+	"fmt"
+)
+
+func main() {
+	verbose := flag.Bool("v", false, "verbose output")
+	flag.Parse()
+	fmt.Printf("Verbose: %v, Args: %v\n", *verbose, flag.Args())
+}
+```
+
+### stdin
+
+```go
+/**/usr/local/go/bin/go run "$0" "$@"; exit;
+package main
+
+import (
+	"bufio"
+	"fmt"
+	"os"
+)
+
+func main() {
+	scanner := bufio.NewScanner(os.Stdin)
+	for scanner.Scan() {
+		fmt.Println("Got:", scanner.Text())
+	}
+}
+```
+
+### File operations
+
+```go
+/**/usr/local/go/bin/go run "$0" "$@"; exit;
+package main
+
+import (
+	"fmt"
+	"os"
+	"path/filepath"
+)
+
+func main() {
+	filepath.Walk(".", func(path string, info os.FileInfo, err error) error {
+		if err != nil {
+			return err
+		}
+		if !info.IsDir() {
+			fmt.Println(path)
+		}
+		return nil
+	})
+}
+```
+
+## Notes
+
+- Adjust `/usr/local/go/bin/go` if Go is elsewhere
+- Semicolon required in `exit;` with `/**/` syntax
+- Avoid dependencies for maximum compatibility
+- Slower startup than interpreted languages (compilation time)
