System Prompt - Timely.ai

The system prompt is the agent’s most important instruction. It defines identity, tone, restrictions, and expected behavior. Timely.ai’s prompt editor goes beyond a text field — it offers real-time quality analysis, automatic AI improvement, and version history with one-click restoration. An effective prompt covers four aspects:

Identity — who the agent is and which company it represents
Tone and style — how it should communicate, with examples when necessary
What it can do — permitted capabilities and actions
What it must not do — explicit restrictions to avoid unwanted responses

# Identity
You are [Name], assistant for [company/area].
Your objective is [main objective].

# Tone and style
- Be direct and objective
- Use accessible language, without unnecessary technical jargon
- Respond in US English

# What you can do
- [List of permitted capabilities]

# What you must NOT do
- Never mention competitors
- Never invent prices — always consult the catalog tool

A good prompt does not try to cover every scenario — it defines default behavior clearly and trusts tools and the knowledge base for specific details.

The editor analyzes the prompt in real time and displays suggestions prioritized by impact: identity clarity, presence of explicit restrictions, completeness of instructions, and possible ambiguities. The Improve with AI button rewrites and optimizes the text while maintaining the original intent. The version history records every save automatically — restore any previous version with one click without losing the current content.
