Automated bug fixes

Automated bug fixes are agent workflows that start from a concrete failure signal: a CI failure, Sentry issue, failed E2E test, bug report, or reproduction step.

The valuable part is not only editing code. A strong bug-fixing agent can also reproduce the issue, explain why it happens, identify the responsible code path, and tell the team when a safe fix is not obvious.

Bug fixes need evidence. Replicas gives the agent a workspace where it can inspect files, run commands, and return a visible trail.

Failure signal arrives

The task starts from CI, Sentry, a human report, Slack, Linear, or another concrete signal.

Agent reproduces or narrows

Replicas can run tests, inspect logs, search code, and identify the most likely failing path.

Fix is attempted

When the bug is scoped enough, the agent edits code and reruns the relevant checks.

Handoff stays reviewable

The result is a PR, test output, reproduction note, or blocker summary for human review.

The best automated bug-fix tasks have a signal the agent can verify. Without that, the right output is often an investigation note rather than a guessed patch.

• Failed tests or CI logs with a clear failure mode.
• Sentry issues with stack traces and affected routes.
• Bug reports with reproduction steps.
• Flaky E2E flows that need repeated runs and logs.
• Regression reports linked to a recent PR or code area.

A useful bug-fixing agent should reduce debugging time without hiding uncertainty. The human reviewer should see what was reproduced, what changed, and what still might be risky.

• Does it reproduce or narrow the bug before changing code?
• Does it run the smallest relevant checks after the fix?
• Does it explain the root cause or only provide a patch?
• Does it avoid broad refactors when a targeted fix is enough?
• Does it return a clear handoff when it cannot safely fix the issue?
