# too many arguments in call to fmt.Sprintf

- **ID:** `go/too-many-arguments`
- **Domain:** go
- **Category:** compile_error
- **Verification:** ai_generated
- **Fix Rate:** 95%

## Root Cause

The number of arguments passed to a variadic function like fmt.Sprintf exceeds the number of format verbs in the format string.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|

| go1.22 | active | — | — |
| go1.23 | active | — | — |

## Workarounds

1. **Match the number of format verbs (%s, %d, etc.) to the number of arguments. Add or remove verbs as needed.** (95% success)

   ```
2. **Use a single %v verb with a struct or map to capture multiple values if the exact format is flexible.** (80% success)

## Dead Ends

- **Removing all arguments except the format string.** — The format string likely contains verbs that need arguments; removing them will cause a different compile error about missing arguments. (90% fail)
- **Adding a newline to the format string.** — Newlines do not consume arguments; the mismatch persists. (95% fail)
