Claude Code found a root cause in 45 minutes, not 1-2 days
An inherited app on Azure, an error, and a hunt that could easily take 1-2 days by hand. With CLI access to Azure and the repo, Claude Code ran the config and network checks and found the root cause in about 45 minutes.

Spotted: found in the wild. Details are as reported by the source above and have not been independently verified.
What they did
Working with an inherited code base deployed on Azure, they pasted an error message or described the symptom to Claude Code, which had CLI access to both the Azure environment and the repo. Claude Code worked through various configuration checks and network tests across the Azure resources, and through the application logic, to find the cause.
How it went
It surfaced the root cause precisely in about 45 minutes with basic human-in-the-loop guidance, work they estimate would otherwise have taken 1-2 days, on a codebase they didn’t build, where they’d have had to learn some of the skills along the way or might not have thought of some of the checks on their own. They note that doing it the long way would have meant deeper, first-hand understanding, with no guarantee they wouldn’t have given up partway through.
Try it yourself with Claude Code
When troubleshooting an unfamiliar or inherited codebase, give your coding agent CLI access to the relevant cloud environment (e.g. [Azure, AWS]) as well as the repo. Paste the exact error message or describe the symptom, and let it work through configuration checks, network tests, and the application logic to surface the root cause, checking in as needed.

Markdown files should just open, so they asked Claude Code for a viewer. It opens instantly: faster, they say, than any other macOS app, and faster than Bitwarden's Chrome extension shows its fill menu.
Migrating a password reset flow, Claude Code and Opus produced code on par with a mid level developer. It needed close supervision throughout, and cost roughly 2 months of Pro subscription for about half a day's work.
A URL shortener side project ran on AWS. Claude Code wrote the GitHub Actions workflows for the move and fixed each failure as it came up. The writer reports zero downtime.
A 7-app monorepo needed an 8 GB memory setting and 25 seconds to typecheck. Claude Code made the changes for the move to oxlint, oxfmt and tsgo, and the team validated each step.
Turning plan files into Claude Code workflows took 5-6 hours each. A script that converts them deterministically, and flags what can move out of the LLM, cut that to 20-30 minutes at about 20% of the tokens.
Running Claude Code in YOLO mode risked projects leaking tokens, so a container setup isolated each project's permissions. Typing a hotkey and a feature name, like text-to-speech streaming, got it done in five minutes.
