The big idea Agents are stateless by default: each task starts blank. To remember things across sessions, they need a memory layer — a file they read at startup, a vector database, or a 'memory tool' like ChatGPT's. Otherwise you'll re-explain your project every morning.
Some examples Claude Code reads `CLAUDE.md` at the start of every session for project context. ChatGPT's memory feature stores facts you've shared (your name, preferences) across chats. Cursor uses `.cursorrules` to remember your team's style guide between agent runs. Custom GPTs use the Files panel as long-term memory the model can search. The rule Without a memory file or tool, every agent session is amnesia — plan for it. Try it! Create a CLAUDE.md or .cursorrules file with 5 facts about your project. Run an agent task. Notice how much smoother it goes.
Define the guardrails first Before an agent runs, spell out what it's allowed to read, write, and delete. Unscoped agents can do unexpected things fast. You did it!

Which sentence best captures the main idea of 'How AI Agents Remember (or Don't) Between Tasks'?
Most agents forget everything when the chat ends — unless you give them a memory system. Tools and goals are unnecessary for agent design Agents should always run without limits or oversight Agents and chatbots are the same thing in every way Which of the following is part of 'Some examples'?
Claude Code reads `CLAUDE.md` at the start of every session for project context. Use the most expensive model regardless of fit Hide tool calls from the operator Run unbounded retries on any error Which of the following is part of 'The rule'?
Hide tool calls from the operator Approve all actions automatically Without a memory file or tool, every agent session is amnesia — plan for it. Ignore cost when scaling Which of the following is part of 'You did it!'?
Ignore cost when scaling Hide tool calls from the operator Memory turns a stranger into a teammate. Use the most expensive model regardless of fit What is 'agent memory' in this context?
A reason to skip all logging A trick to bypass approvals A core concept covered in How AI Agents Remember (or Don't) Between Tasks A way to disable the agent's tools What is 'stateless' in this context?
A core concept covered in How AI Agents Remember (or Don't) Between Tasks A reason to skip all logging A trick to bypass approvals A way to disable the agent's tools What is 'context file' in this context?
A trick to bypass approvals A reason to skip all logging A way to disable the agent's tools A core concept covered in How AI Agents Remember (or Don't) Between Tasks Which is the safest default for an agent's long-term memory?
Store only what is needed for the task, with clear opt-in and easy deletion Never store anything ever Hide what is stored from the user Store everything forever, by default Which signal best tells you an agent is stuck in a runaway loop?
It finishes the task in one step It keeps repeating the same tool call with no new progress It asks one clarifying question It returns a short summary and stops Which budget control most directly prevents runaway costs from an agent loop?
A friendly system prompt A bigger model A hard cap on steps, tokens, or dollars per task A longer context window What is the safest first place to deploy a brand new agent?
A sandbox or low-stakes task with reversible actions On a public server with no auth Inside a critical billing system Production, against real customers What should an agent's trace let you do after a run?
Replace the need for any tests Reconstruct each step, decision, and tool call so you can debug or audit Make the agent run faster next time automatically Hide what the agent did from the user What does an 'eval' for an agent measure?
Whether the agent reliably completes a defined task end to end The exact wording of every prompt How polite the model sounds The temperature setting Why is keeping a human in the loop valuable for high-stakes agent actions?
It removes the need for any logging It catches mistakes before they cause real-world harm It speeds the agent up It replaces the model entirely Before letting an agent take a destructive action, what is the safest default?
Skip approvals if the user trusts the agent Hide the action from any log Require explicit human approval for the specific action Approve once and let the agent repeat forever
