What they did
Sick of k9s being slow, buggy and memory-hungry, he vibe-coded k9rs, a Kubernetes terminal UI in Rust, under close supervision of the design and ownership model.
Result (as claimed)
It has been stable and is now his daily driver.
Tools they used
Cost: Pricing depends on the tools you pick; check each official pricing page.
Set it up
Pick a contained repo or task
Start on a branch or side project where mistakes are cheap.
Install and configure
Set up AI coding agent, Rust, Kubernetes. Read what it can run on your machine and limit permissions where possible.
Run it on a real task
Give it a well-scoped issue and let it work. Review the diff like any pull request.
Add guardrails
Keep tests and CI in the loop, and never let an agent push to main or touch production secrets unattended.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
You are helping me set up this AI use case end to end in Claude Code. Goal: Vibe-code a faster replacement for a slow dev tool you use daily What the original author did: Sick of k9s being slow, buggy and memory-hungry, he vibe-coded k9rs, a Kubernetes terminal UI in Rust, under close supervision of the design and ownership model. Reported result (as claimed by the author): It has been stable and is now his daily driver.

Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like). 2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure. 3. Then do the setup with me one step at a time, waiting for my OK before anything that sends messages, posts publicly, spends money or deletes data. 4. Finish with a checklist to run it again next time.
