AI bug fixing and flaky test repair

Get the failing test, cause, and fix without losing a day per bug

Paste the bug report, logs, or steps. The agent reproduces the bug with a failing test, finds the cause, and fixes it, guarded by a regression test. Your engineers review the evidence instead of losing a day to the investigation.

See how the test demonstrates the fix

A fix without a failing test is a guess. Each pull request carries three frames of evidence, so the reviewer can see the bug, the change, and the result without running anything.

01 · RED08:41
✗ sums line items to the cent main @ 3f2a91 expected 10.00, got 10.01
The test fails on main. The bug is real and pinned.
02 · CAUSE09:12
- lines.map(l => round(l.qty * l.price))+ lines.map(l => l.qty * l.price)+ return round(sum, 2)
One change, at the root. Two similar spots fixed too.

Flaky tests

Investigate the timing behind flaky tests

The agent runs a flaky test until the pattern shows, reads what it waits on, and replaces guesswork with a real signal. It opens a pull request only after twenty green runs in a row.

An honest answer

Review the report when a bug won’t reproduce

Some bugs need production data or a customer’s setup. The agent stops at its budget cap and tells you what it tried and what it needs. No speculative patches reach your branch.

Frequently asked questions

What do agents do with a bug report?
Paste the bug report, logs, or steps. The agent reproduces the bug, writes a failing test first, fixes the root cause, and opens a pull request, so the fix is guarded by a regression test.
How do agents fix flaky tests instead of muting them?
The agent runs a flaky test until the pattern shows, reads what it waits on, and replaces the guesswork with a real signal. It opens a pull request only after twenty green runs in a row.
What happens when a bug won’t reproduce?
The agent stops at its budget cap and reports what it tried and what it needs, such as production data or a customer’s setup. No speculative patches reach your branch.
How do I hand a bug to an agent?
Paste the bug into a task in the Desktop App or the CLI, and add your test commands. A fix only opens a pull request with a failing-then-passing test attached.
