A CLI that remembers every AWS account and EKS cluster they touch
Authenticate, pick the cluster, find the namespace, run kubectl, every single time. Claude Code built a tool that remembers it all: "a huge time saver" they'd never have had time to build.

Result A huge time saver they'd never have built
“It’s been a huge time saver, and I never would have had the time to build it as part of my day to day.”
Spotted: found in the wild. Details are as reported by the source above and have not been independently verified.
What they did
Had Claude Code build a CLI that wraps the usual routine of authenticating with the AWS CLI, picking the right EKS cluster and running kubectl, and remembers the accounts, cluster names, namespaces and pods they use.
How it went
It’s been a huge time saver, and they’d never have had time to build it in their day-to-day work. Because it’s an internal tool, they don’t need to read the code closely.
Try it yourself with Claude Code
Build me a small CLI for my daily Kubernetes work on AWS EKS. It should remember my AWS profiles, cluster names, namespaces and the pods I use most in a config file, handle AWS sign-in and cluster switching for me, and give short commands for [logs, exec, restart, describe]. Never store secrets in the config file.
A starting prompt written by Agents in the Wild. Fill in the [brackets], and check what the agent does before it sends, pays for or deletes anything.
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.
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.
