How to write AI agent instructions that get better over time: have the bot draft a tighter version of its own rules, then you approve the changes.

My bots' instructions used to pile up. Now each bot keeps one short, optimized set of rules, and I approve every change to it.

Tell the Bot when you discover a lasting preference, boundary or responsibility, and ask it to remember (source). A finished process can become a saved skill (source).

Prompts

When to use it: When instructions have grown long.

Rewrite your standing instructions to be shorter. Keep every rule, merge duplicates, and show me the before and after for approval.

When to use it: Turning a good process into a skill.

That process worked. Save it as a skill so you can repeat it the same way.

Sanitized from my own prompts: names, accounts and private details removed.

Why This Matters To Me

I was an overworked and overwhelmed one-person shop trying to run a six-figure business alone, because hiring here is so expensive. Grok Bot helped me accomplish things I never thought were possible. The full story starts in How To Set Up An AI Assistant With Grok Bot.

Quick Answers

How Long Should A Prompt Be?

Short and specific: a role, a task, the rules and what done looks like.

Can A Bot Learn A Task By Watching Me?

Yes. Walk a bot through a task once and it can save it as a skill and rerun it on a schedule. As of Oct 2026, per the Grok Bot docs.
