How to use Instructions to personalize your Agents
Using Instructions with your 913.ai Agents
Last updated About 1 month ago
Think of Instructions as little notes you give to your agent about how you want it to behave. Instead of reminding it every single time, you just write down the instructions once, and your agent will remember them for you.
Instructions are like your personal instructions. The agent will treat them as top priority and always try to follow them when helping you.
Why Use Instructions?
Without instructions, your agent will just respond in a general way. With instructions, you can shape how it talks, how it writes, and how it behaves.
Here are some examples:
Email style instruction:
βWrite my emails short and polite. Always start with βHi [Name],β and end with βThanks, [My Name].ββ
Tone instruction:
βTalk in a friendly, casual way. Imagine youβre texting a friend.β
Role instruction:
βBehave like a lawyer. Use formal language, reference laws, and keep answers professional.β
Formatting instruction:
βWhenever you make a list, always use bullet points.β
Creative instruction:
βWhenever you suggest ideas, always give me at least three options.β
π The best part? You only need to write your instructions once per agent. After that, they apply across all chats with that agent.
How to Add Instructions
Go to the top menu on your right side of screen and click on Instructions.

The Instructions pop up will open. This is where you type your instructions.

Once saved, the instruction are linked to you only. Your team members wonβt see or be affected by your instructions.
If you're in a project, you can set instructions specifically for that project. These instructions will automatically apply to all chats and all agents within the project.
Best Practices (Simple Tips)
Be clear and specific
β βWrite emails in this format:β
β βMake my emails nice.β
Keep it short
β One or two sentences per rule.
β A giant wall of text.
Donβt overload
Too many instructions can confuse the agent. Stick to the important ones.
Instructions Are User-Specific, Not Team-Specific
Itβs important to know: instructions belong only to you.
Your teammates cannot see your instructions.
Your teammates cannot use your instructions.
If you and a teammate both use the same agent, your agent will follow your instructions, and theirs will follow their instructions.
β This means you can customize your agents without worrying about messing up how your colleagues use theirs.
Conflicting Instructions
Sometimes people try to write two instructions that say opposite things. For example:
β βWrite emails in a short, casual style.β
β βWrite emails in a long, formal style.β
Or:
β βFormat emails with bullet points.β
β βFormat emails with numbers.β
This can confuse the agent. The agent might not know which one to follow, and the results wonβt be consistent.
π Best practice: If you want your agent to write emails in a special way, just give one clear example instead of two.
β Example of a good instruction:
βWrite emails in this format:
Hi [Name],
Here is the update you asked forβ¦
Thanks, [My Name]β
More Example Instructions
Hereβs a bunch of ideas you can copy and tweak:
βAlways answer in a calm, reassuring tone.β
βWhen I ask about numbers, show the answer in a table.β
βKeep replies under 200 words.β
βAdd emojis at the end of casual messages π.β
βWhen writing product updates, use bullet points with titles in bold.β
βIf I ask about documents, summarize them in 3β4 sentences.β
βIf I ask for a joke, keep it family-friendly.β
