BugBot: from production error to verified fix

Production error monitoring is very good at telling teams that something broke. The hard part begins immediately afterward: sorting duplicate alerts, identifying the responsible revision, reproducing a user’s failure, editing unfamiliar code, and proving the repair did not create a new regression.

BugBot is our attempt to close that entire loop. It is designed to turn a connected production error into a review-ready fix without asking an engineer to manually shepherd every mechanical step. The evidence remains visible and the final release decision remains under your team’s control.

The automatic fixing loop

1. Turn noisy alerts into one incident

BugBot starts with the production signal. It groups repeating occurrences that share the same failure signature so ten thousand events do not become ten thousand investigations. The incident keeps the useful context: stack information, affected route or job, deployed revision, and timing.

2. Reproduce before touching code

An error message is not yet a diagnosis. BugBot checks out the original revision in an isolated environment and attempts to reproduce the reported behavior. That creates a crucial baseline: a deterministic failure that exists before any proposed repair.

3. Generate the smallest practical patch

Once the failure is reproducible, BugBot traces the relevant execution path and proposes a scoped code change. The aim is not to rewrite a subsystem or clean up unrelated code. It is to address the observed failure with the smallest change that can be explained and tested.

4. Verify independently

The agent that proposes a change should not get to grade its own homework. Verification replays the original reproduction against the patched revision, adds focused regression coverage where appropriate, and runs the relevant quality gates. A passing unrelated test suite does not count as proof.

5. Hand the team receipts, not confidence theater

The output is a review-ready change with a root-cause explanation, the exact behavior observed before the patch, the passing behavior afterward, and targeted test results. Teams can review, request changes, merge, and deploy through their existing controls.

“Failure before, pass after” is the contract

Automatic fixing only becomes useful when it is falsifiable. BugBot’s core contract is simple: demonstrate that the reported problem fails on the original revision, apply the proposed repair, and demonstrate that the same check passes on the patched revision.

What “automatic” does—and does not—mean

BugBot automates the investigation and repair loop: de-duplication, reproduction, diagnosis, patch generation, and verification. It does not mean silently changing production. The private preview is designed around reviewable changes and human-controlled merge and deployment policies.

That boundary matters. Many bugs are safe candidates for automatic repair; others expose unclear requirements, risky migrations, or architectural decisions that need a person. BugBot should be able to say that it lacks sufficient evidence instead of manufacturing certainty.

Guardrails before speed

• Isolated execution: reproduction and repair run away from production systems.
• Scoped access: repositories, services, and tools are limited to what the incident requires.
• No automatic merge by default: teams retain their existing approval and release controls.
• Evidence thresholds: no verified-fix verdict without a reproducible before-and-after result.
• Secret hygiene: credentials and sensitive payloads are redacted from agent context and evidence.
• Idempotent incident handling: duplicate signals should converge on one investigation, not create competing fixes.

A concrete example

Imagine checkout requests begin returning a 500 after a deployment. The production event points to a missing currency value in one legacy account path. BugBot groups the repeated errors, checks out the deployed revision, and creates a focused request fixture that reproduces the 500.

It traces the path to an unsafe assumption, adds the narrow fallback required by the existing domain rules, and replays the fixture. The 500 becomes the expected response, the focused regression test passes, and adjacent checkout tests remain green. Your team receives the proposed change and that complete before-and-after chain—not just a message that an AI is “confident.”

Run it where your code and evidence need to stay
