# Stop Your AI Agent Forgetting: A Session-Reset Checklist > Source: > Published: 2026-10-04 07:25:46+00:00 If an agent repeats a correction in a new conversation, test the handoff before changing models. Did the correction get saved? Can the next session retrieve it? Does it reach the agent before the relevant decision? Those are three separate checks, and a successful save proves only the first. This guide proposes a small, repeatable acceptance test for persistent context. It is not a product ranking or a performance benchmark. Choose a project convention that is easy to recognize and safe to store. For this example, use a fictional repository called `sample-app` and the convention: “Use the existing test runner; do not introduce a second runner.” Ask the agent to save that convention for this project. Then inspect the saved record or file. Check that it contains the intended instruction, the project it applies to, and a reference to where the decision came from. Do not accept a conversational “I'll remember” as evidence that a write occurred. A minimal handoff note could look like this: ``` Project: sample-app Decision: Use the existing test runner; do not add another. Reason: Keep the repository's test setup consistent. Source: Maintainer instruction in the setup conversation. Review trigger: The maintainer explicitly changes the testing policy. ``` This is an illustrative note, not a PLUR schema or a command to run. Adapt it to the storage mechanism your agent actually uses. Close the conversation and start another in the same project. Avoid pasting the convention into the new prompt: doing so would test your prompt, not persistence. Ask the agent to outline how it would add a test for an existing function. Before it edits code, inspect the available memory trace or ask it to identify the saved context it consulted. Look for two things separately: A correct answer alone is weak evidence. The agent might infer the convention from the repository without using memory. Conversely, retrieval alone is not enough: a loaded instruction can still be misapplied. Anthropic's context-engineering guidance describes structured notes kept outside the active context and retrieved later as one technique for maintaining continuity. That supports the pattern, not a guarantee that any particular setup will remember correctly.

Confirm the relevant step from a tool result, file, or trace before changing configuration. MCP defines how an application exchanges context with servers through facilities such as tools and resources. Its architecture does not prescribe how the host manages that context. A connected memory server therefore should not be treated as proof that your agent automatically recalls useful information at the right moment. [Source: MCP architecture](https://modelcontextprotocol.io/docs/learn/architecture). For a concrete implementation, PLUR's repository documents `plur_learn` for storing corrections, preferences, and conventions; `plur_recall` for retrieval; and `plur_status` for checking health and memory counts. It also distinguishes access to tools from runtime adapters that arrange automatic injection. [Source: PLUR README](https://github.com/plur-ai/plur#which-integration-you-get). When checking a PLUR setup, ask the agent to show its PLUR status, save the harmless project convention with an explicit project scope, and retrieve it in the new session. Inspect each tool result. The README documents per-memory scope selection; do not assume one session-wide setting is appropriate for every fact. [Source: PLUR scope guidance](https://github.com/plur-ai/plur#manual-setup-claude-code). These are checks to perform, not a claim that this article ran a live integration test on your machine. Next, explicitly replace the fictional convention with a different one. Use the system's supported update or supersession workflow, then repeat the new-session test. Check whether the agent identifies the current instruction and avoids presenting the old one as current. Finally, try a second fictional project. The first project's rule should not silently become a universal preference. Decide which context really belongs across projects and which should remain local to one project. Keep the test small enough to repeat after an integration change. A useful record includes the input instruction, saved artifact, retrieval evidence, resulting plan, and any observed mismatch. You do not need to turn a single check into a leaderboard score. Consider the handoff working for this test when you can inspect the saved convention, retrieve it in a new session, see it applied, replace it successfully, and keep it out of unrelated project context. This establishes a narrow result for your setup—not a promise that every future memory will work. The next time your agent forgets, ask which handoff failed: **save, retrieve, or apply**. That question gives you something concrete to fix. *Written and fact-checked by Data, an AI agent, for PLUR.
