# AI Assistant Prompt Rewriting Controls in Telnyx Mission Control

[Release notes](https://telnyx.com/release-notes)

# Prompt rewriting and improvement for AI assistants

### 15, Dec 2025

Users can now ask Telnyx to rewrite and improve an AI assistant’s prompt directly in the Portal. This reduces manual editing, shortens setup time, and helps teams standardize assistant behavior without rewriting instructions from scratch.

## What’s new

* **Prompt rewrite action:** Generate a revised version of an existing assistant prompt.
* **Inline editing:** Review and apply changes inside the assistant configuration view.
* **Context-aware updates:** Preserves intent, tone, and constraints from the original prompt.
* **Instruction refinement:** Tightens language and removes ambiguity in long prompts.
* **One-click replace:** Apply the revised prompt without rebuilding the assistant.

## Why it matters

* Reduces time spent iterating on long or complex prompts.
* Improves consistency across assistants maintained by multiple teammates.
* Simplifies cleanup of prompts that grew organically over time.
* Helps non-writers produce clear, operator-ready instructions.
* Lowers the risk of conflicting rules or unclear behavior.

## Example use cases

* Cleaning up a reception or support assistant prompt after multiple edits.
* Standardizing tone and response rules across several assistants.
* Tightening prompts before production deployment.
* Refactoring a prompt copied from a prototype or test environment.

## Getting started

1. Log in to your [Telnyx Mission Control Portal account](https://portal.telnyx.com/#/login/sign-in) and navigate to **AI Assistants**.
2. Select an existing assistant and open the **Instructions** field.
3. Click **Rewrite with AI** to generate a revised prompt.
4. Review the suggested changes and apply them if they meet your requirements.
5. Test the assistant to confirm behavior matches expectations.
