An autonomous agent's memory design should answer a practical question: **if the process stops now, what will the next run need to continue correctly?** Start with a small, inspectable record of the goal, confirmed progress, unresolved decisions, and reusable lessons. Then test whether a new session can find and use that record.

This is an engineering checklist, not a ranking of memory products. The examples below are proposed application designs, not claims that a particular memory tool implements the entire workflow automatically.

Use two records with different jobs:

For example, “the report has been uploaded; its receipt is in the job record” belongs in the checkpoint. “Reports for this project must include the source dataset” is a candidate for reusable memory.

Anthropic describes structured note-taking as writing persistent notes outside the context window and loading them again later. Its context-engineering guidance also treats compaction as a separate technique, with a risk of losing important details when summaries are too aggressive. That supports using an explicit checkpoint instead of assuming a conversation summary will preserve every operational dependency. [Source: Anthropic's context-engineering guide](https://www.anthropic.com/engineering/effective-context-engineering-for-ai-agents).

For each completed step, preserve a pointer to something the next run can inspect: a file, commit, job identifier, or service receipt. Avoid treating “I finished the task” as sufficient evidence.

Here is a deliberately small application-level checkpoint format:

```
objective: prepare the release notes
completed:
  - action: collect merged changes
    evidence: artifacts/merged-changes.json
pending:
  - verify breaking changes with the release manifest
next_action: open the manifest and compare it with the collected changes
```

This is illustrative YAML, not a PLUR API schema. Keep secrets out of such records; store references to the authorized credential mechanism instead.

Define the startup sequence before choosing retrieval settings:

As a design rule, retrieve a focused set of lessons rather than automatically injecting every old note. Set a context budget and inspect which records actually arrive in the prompt. A successful search request is not proof that the returned information helped the agent.

A stored lesson such as “the release process ends with publication” should not itself authorize publishing a new release. Keep permissions in the current workflow's policy and user instructions.

Likewise, a remembered service response should not replace checking the service when the next action depends on its current state. In this design, memory provides context and evidence pointers; it is not a substitute for operational verification.

PLUR is one implementation of the reusable-memory part of this design. Its repository documents plain-text YAML memory, the `plur_learn` tool for storing corrections or conventions, and `plur_recall` for retrieving relevant memories. It also documents selecting a scope for each learned item, so project-specific knowledge need not be treated as global knowledge. [Source: PLUR repository](https://github.com/plur-ai/plur).

Those primitives do not by themselves establish that a job's external actions succeeded. Keep the application checkpoint and action receipts alongside the memory integration.

One important distinction: PLUR's tool documentation describes `plur_forget` as retiring a memory, with activation decaying and eventual pruning. Do not treat that description as a guarantee of immediate deletion from every copy or backup. [Source: PLUR tool reference](https://github.com/plur-ai/plur#tools).

Try these acceptance checks with a disposable task:

Record the observed outcomes. Do not infer reliability from the mere presence of a memory file.

The starting recommendation is simple: build the restart contract first, add reusable memory second, and evaluate both together. A new session should be able to explain what is confirmed, what remains uncertain, and what it can safely do next.
