From Bug Report to Merged PR in Under 20 Minutes

(Sample post drafted from my work notes - edit before publishing.)

Most engineering organizations treat bug fixing as a queue problem: triage, assign, wait for a free engineer, context-switch, fix, review, merge. Each handoff adds hours. We asked a different question: how much of that loop can agents run, with humans only at the decision points?

The answer became Maestro, our AI-powered bug-fix orchestrator. It’s a multi-agent pipeline - an analyser that reproduces and localizes the defect, a fixer that proposes the change, a validator that runs the test suite against it, and a git agent that shepherds the branch - with two properties we considered non-negotiable:

1. Human approval gates. An engineer approves the diagnosis before a fix is attempted, and approves the diff before it merges. The agent does the legwork; the human keeps the judgment.
2. Workspace isolation. Every fix runs in an isolated workspace, so a wrong hypothesis never touches shared state.

The result: for a meaningful class of bugs, engineers go from bug report to merged PR in under 20 minutes - not because anyone types faster, but because the waiting between steps disappeared.

The deeper lesson for engineering leaders: the win from agentic AI isn’t replacing engineers, it’s deleting the queue time between human decisions. Design your pipelines around the decision points, and automate everything between them.
