# Backlog cleanup agent: how to triage engineering work with AI

Backlog cleanup is engineering work. Replicas helps teams triage stale issues, validate old tasks, group related work, and turn actionable items into reviewable outputs.

## What is backlog cleanup?

Backlog cleanup is the process of reviewing old issues, stale tasks, ambiguous requests, duplicate work, and low-signal tickets so the team knows what still matters.

A coding agent can help because cleanup often requires repository inspection, product context, test runs, bug reproduction, and judgment about whether an issue is still actionable.

## How Replicas approaches backlog cleanup

The best backlog cleanup agent does not blindly close issues. It separates stale noise from real engineering work and returns evidence.

- **Select a slice:** Start with a label, project, milestone, repo area, or stale issue set instead of the entire backlog.
- **Inspect reality:** The agent checks current code, docs, tests, recent commits, and linked PRs to see whether the issue still applies.
- **Group and classify:** Replicas can identify duplicates, blocked tasks, quick fixes, product questions, and issues that need human prioritization.
- **Return useful outputs:** The result may be a cleanup summary, suggested closures, grouped issues, PRs for small fixes, or follow-up tasks for humans.

## Backlog cleanup outputs are not always PRs

Backlog work often creates information before it creates code. That is still valuable engineering output.

- A list of stale issues that appear fixed by current code.
- Duplicate groups with recommended canonical issues.
- Small PRs for obvious cleanup tasks.
- Reproduction notes for bugs that still exist.
- Clarifying questions for issues that are too vague to implement.
- A prioritized follow-up list for the next engineering planning pass.

## How to evaluate backlog cleanup automation

The risk in backlog cleanup is false confidence. The agent should show evidence, avoid over-closing, and make human review easier.

- Does it cite files, commands, issues, and linked PRs behind each recommendation?
- Does it distinguish stale, duplicate, blocked, vague, and actionable work?
- Does it create small PRs only when the implementation is clear?
- Does it preserve human prioritization for product decisions?
- Does it reduce planning time without hiding uncertainty?

## FAQ

### Can Replicas clean up an entire backlog?
It is better to start with a scoped slice such as one label, repo area, or stale issue set. That keeps the output reviewable and avoids broad unsupported claims.

### Does backlog cleanup mean closing issues automatically?
No. Replicas is most useful when it produces evidence and recommendations that humans can review before closing, merging, or reprioritizing work.

### Can backlog cleanup produce PRs?
Yes, but only for clearly scoped tasks. Many backlog cleanup sessions should produce summaries, triage notes, duplicate groups, or clarification requests.
