If your AI agent keeps asking for decisions you already made, test the handoff between sessions: save a small set of durable facts, make those facts available to the next session, and check that the agent uses them correctly. Treat each stage as something to verify, not something implied by a successful conversation.
This guide proposes a lightweight workflow you can adapt to your agent. It is not a benchmark or a promise that installing a memory tool eliminates every repeated explanation.
A resumed conversation and a fresh conversation with access to earlier knowledge are different tests. LangChain’s memory documentation distinguishes thread-scoped state from long-term memory shared across threads. That distinction is useful even if you do not use its framework: decide whether you need to resume a particular task or carry a decision into a new task. Source: memory overview.
For a session handoff, keep two small records:
Do not promote every sentence of a transcript into a standing instruction. An experiment, a rejected proposal, and a confirmed decision deserve different treatment.
Ask the agent to propose a short handoff before saving it. Review ambiguous decisions instead of letting the summary silently resolve them.
Here is an illustrative template, not a PLUR schema or executable configuration:
Project: checkout-service
Completed: added a regression case for duplicate requests
Next step: inspect the failing retry path
Decision: retries must reuse the original idempotency key
Evidence: decision note in the repository
Applies to: checkout-service retry handling
Still uncertain: whether the upstream timeout is configurable
Prefer a precise rule with its reason and scope over “remember everything about checkout.” Keep the unfinished action in task state; keep the confirmed retry rule in durable knowledge.
After saving, inspect the stored record or use the memory system’s supported read operation. Check the content and destination, not just the agent’s acknowledgment.
Use these questions:
For PLUR, the repository documents plur_learn for storing corrections, preferences, and conventions, and plur_recall for retrieving relevant memories. Its default local memory format uses YAML engrams. Those operations provide a concrete place to inspect the save-and-recall boundary. Source: PLUR README.
Open a new conversation using the same intended project and memory configuration. Do not paste the answer into the prompt: that tests whether the agent can read your prompt, not whether the handoff worked.
Try a task-shaped question:
I am changing retry handling in checkout-service. Which existing decision should constrain the change, and where did it come from?
Look for the correct rule and its source. If the agent supplies an unsupported explanation, record that separately from a successful retrieval. Finding a memory and reasoning correctly from it are separate acceptance criteria.
Repeat the query in an unrelated project. Your intended outcome should be explicit: a checkout-specific constraint should not be presented as a universal rule for every service.
PLUR’s documentation describes scopes such as project:myapp and a per-memory scope on plur_learn. It also notes that global knowledge can be included in project recall. Choose a project scope for a project-specific rule; do not assume that the word “global” means private to the current task. Source: PLUR README.
Treat this as a configuration test. Verify actual behavior in the runtime you use rather than inferring it from the presence of a memory server.
In a disposable test project, change the example rule and repeat the fresh-session query. Use the storage system’s documented correction or retirement workflow, then inspect the result.
The acceptance condition is not merely “the new text exists.” It is “the agent no longer treats the old rule as the active decision.” If both versions appear, require evidence that identifies which one supersedes the other.
Do not confuse retirement with immediate physical deletion. PLUR describes plur_forget as retiring a memory, with activation decay and eventual pruning. This checklist does not claim erasure from every copy or backup. Source: PLUR tools reference.
Before relying on cross-session memory, confirm:
If a check fails, isolate the stage: capture, storage, scope, retrieval, or use in the answer. Fix that boundary and repeat the same small scenario before adding more memories.
The goal is not an agent that claims to remember everything. It is a handoff you can inspect and repeat.
