Treena Bugs don't check your calendar. The alert arrives at dinner, on the trail, in the checkout line — precisely when the laptop is elsewhere. The traditional playbook is grim: acknowledge the page, apologize in the channel, race home, boot up, and *then* start debugging. The bug gets thirty minutes older before anyone touches code. Here's the pocket-scale version. ## 1. Open the repo cold No desktop session to resume, because none is needed. Sign in, open the repo, and a cloud workspace clones it fresh. You're looking at the same `main` your production build came from. ## 2. Point the agent at the evidence Paste the stack trace or describe the symptom. A coding agent with repo access does what you would do at a desk, faster: - Search for the failing code path - Read the surrounding logic and recent history - Propose a diagnosis you can sanity-check You know your system; the agent knows where everything is. That division of labor works on a five-inch screen. ## 3. Patch in plan mode For a production fix, ceremony is a feature. Plan mode drafts the change before a single line moves — you approve the approach, then the agent edits. On a phone, reading a short plan is easier than writing a long prompt, and much easier than typing the patch yourself. ## 4. Prove it A fix you didn't test is a second incident. The workspace is a real machine, so the proof is real too: - Run the failing test, watch it pass - Run the suite around it - Add the regression test the bug deserved all along ## 5. Ship and follow up Review the diff line by line — it's a diff, not a wall of chat. Commit, push, open the PR. Your CI and your review process take it from there, same as any desk-born fix. ## The point isn't heroics Nobody should run their whole on-call from a phone. The point is the gap between *"I saw it"* and *"the fix is up for review"* no longer has to include a commute. Fifteen minutes of steering from wherever you are often beats an hour of delay followed by the same fifteen minutes. Incidents age badly. Fixes shouldn't have to wait for a desk.
