Long-Running AI Agent Tasks: Background Jobs with LibraOS

Some agent work fits in a single request: look something up, draft a reply, answer a question. Other work doesn't. Reviewing a month of support tickets, preparing a research summary or working through a long list of records can take minutes or hours, and nobody wants to keep a browser tab open for that long.

These tasks run in the background, and they behave differently from quick ones. They can be interrupted, they can fail halfway through, and they often need a person's decision somewhere in the middle. This guide covers how to design long-running agent tasks, how that fits with the LibraOS Runtime, and the limits to plan around.

How long tasks differ from quick ones

A quick task either works or fails in one go. A long task has a life: it starts, makes progress, may wait, and finishes or doesn't. That creates requirements a short request never has.

When in doubt, ask one question: if this task stopped right now, could someone tell what was finished, what wasn't, and how to continue? If not, it isn't ready to run unattended.

What it looks like in practice

Imagine a support team that wants a weekly review of open tickets, in the spirit of the Customer Desk concept on the LibraOS homepage, a CRM and ticket-management demo built on sample data. Every Monday, an agent should go through the open tickets, summarize each one, flag the ones that need attention and propose follow-ups.

Designed as a long-running task, it looks like the list below. These are design goals for your app; check which ones your LibraOS setup supports directly.

1. Split the work. Treat each ticket as its own small step rather than one giant request.
2. Read freely. Reading tickets and gathering context needs no approval, so the agent works through them without stopping.
3. Draft, don't send. Follow-up messages are drafted and stored, not sent.
4. Stop at side effects. Any message that goes out, credit that is issued or status that changes waits behind an approval point, without holding up the reading and drafting of other tickets.
5. Report progress. The team can see how many tickets are done, how many are waiting for review and whether anything failed.
6. Finish with a summary. A person gets one result they can act on, with the pending decisions listed.

The split is the point. The agent does the slow reading and drafting in the background. The decisions that change data or contact customers stay with a person.

Setting it up with LibraOS

The LibraOS Runtime has four parts: agents that coordinate tasks and connect tools, memory that carries useful context across sessions, knowledge that retrieves from your connected sources, and Control, which defines policies, approvals and audit. For the tasks your app runs through LibraOS, the design decisions are yours:

• Break the job into steps. Smaller steps are easier to resume, retry and review.
• Set permissions. Decide what the agent may do and with which tools, so a long unattended run stays inside clear boundaries.
• Place approval points. Put them before side effects such as sending, refunding or changing a record, and plan, in your app, what happens if no one responds in time.
• Configure audit. A long task makes many decisions while nobody is watching. The record lets you review what it did afterward.
• Plan for resuming. Recovery after an interruption depends on the workflow. Don't assume every agent or external action resumes on its own; read the durable-run limits and design your steps around what your edition and version support.

Before launch, test the failure paths, not only the happy one. Interrupt a run partway, make a tool fail, leave an approval unanswered, and check that the task and its record behave the way you expect. Check knowledge access, tools and approval behavior against your app's real actions, using realistic data.

Where the controls apply

Tasks that run inside the Runtime get its permissions, approvals and audit. If you route only a model request through LibraOS, controls apply at that request. Tools, shell commands and network activity outside the Runtime need their own enforcement.

Long tasks make this limit sharper. If a step calls a payment or email API directly from your app's own code, an approval point inside the Runtime can't stop it, and a retry in your code can repeat it. Map every tool with side effects, and make sure each one runs inside the Runtime or has its own check.

Resources are a practical limit too. A long run uses compute, model calls and connected systems for as long as it lasts, so decide where it runs and what it is allowed to consume. LibraOS can be self-hosted on your own servers or in containers, or run on LibraOS Cloud (private beta), so check the requirements for the setup you choose.

Common mistakes

• One giant step. If the whole job is a single call, any failure means starting from zero. Break it into resumable steps.
• Retrying side effects blindly. A retry that sends the email twice or issues the credit twice is worse than a failure. Make side-effect steps safe to repeat, or check whether they already happened.
• Unlimited retries and loops. Cap attempts, steps and total runtime, and decide what happens when a cap is hit.
• Waiting forever for approval. A task blocked on an absent reviewer ties up work indefinitely. Set a time limit, notify the right people and define a fallback, such as expiring the request.
• Silent failures. If nobody is told when a run fails, the problem surfaces days later. Report failures and stuck tasks.
• No way to cancel. People change their minds, and bad runs happen. Make stopping a task a supported action.
• Gating everything. If every read needs a click, reviewers stop reading. Put approval points on side effects only.
• Running side effects outside the Runtime. Approved actions carried out by your own code are not covered by the Runtime's controls. Keep them inside, or give them their own enforcement.
• Assuming every run resumes on its own. Recovery depends on the workflow. Check the durable-run limits before relying on it.
• Skipping the failure tests. Interrupt, fail and delay your task before users depend on it.

Conclusion

Long-running agent work succeeds when it is designed to be interrupted: small steps, saved progress, safe retries, clear status and a clean pause for human decisions. Let the agent do the slow reading and drafting in the background, and put every action with side effects behind an approval point. With LibraOS, you configure permissions, approval points and audit for the tasks your app runs through the Runtime, check the durable-run limits for your setup, and make sure every side effect actually runs there.

LibraOS runs the agents, controls and audit around this work; how a run is resumed after an interruption depends on the workflow, so the design choices below are yours.
