Agent Memory

You might say

I have to restate my requirements in every new conversation. So annoying.

A mechanism that lets an Agent remember your preferences, project conventions, and past conclusions across sessionsInstead of repeating constraints like 'use Tailwind' and 'never edit this folder' in every new chat, memory mechanisms and project rule files let new sessions inherit them automatically. Chat history vanishes once a session closes, while team-wide technical rules remain most reliable in committed rule files.

Agent Memory

One preference, three locations, different results

Yesterday's instruction in session 1:“In this project, never edit shared component Navbar.tsx.”Lost when closed

Today's new chat (Session 2)

You (no repeated rules)

Please add a search box to the top right of the page.

AI Agent

Done! I added the search box directly into Navbar.tsx.

❌ The AI forgot yesterday's rule and touched Navbar.tsx. You have to restate constraints every time.

Chat-only rules get lost immediately; writing project conventions into rule files ensures every new session inherits them.

How long each location keeps it

In chat: this session only: It applies only to the current conversation; a new chat needs it restated, and forgetting removes the constraint.

Project rules: with the project: Written into a rules file or team config, it loads into every new conversation; checkable and shareable, suited to project-level conventions.

Memory: across sessions: The Agent's memory keeps preferences and past conclusions across conversations; exact support depends on the product.

Quick checkChoose the best answer

You want every new project to default to do not auto-edit shared components. Where should the preference live?

Write it into project rules or team config so every new conversation loads itRestate it in the chat every time a new conversation startsRely only on the Agent's memory mechanism to remember it

You can say this to an AI Agent

This preference must apply from now on: do not automatically edit shared components. Write it into the project rules rather than only this conversation; after writing it, open a new conversation and confirm the rule still applies.
