# AIP010 — redundant-instruction
**Category:** best-practice **Severity:** warning
## What
Detects instructions that repeat the same directive multiple times across a prompt.
## Why it matters
Redundant instructions waste tokens and dilute clarity. Each unique instruction should appear once; repetition may indicate a copy-paste error or a misunderstanding of how instructions compose.
## Example
```
Be concise.
Be helpful.
Be concise. <-- repeat
Keep responses short. <-- similar to "be concise"
```
## Fix
Consolidate into a single, clear directive:
```
Be concise, helpful, and accurate.
```
## Autofix
This rule includes a safe autofix that removes duplicate exact lines.
