# Tool-stack upgrade scout

Have an agent find faster replacements for the tools in your dev stack (e.g. pip to uv, node to bun), test them on your code and write a CTO-ready summary, a copy-paste prompt Rafal Wilinski says cut his team's CI time by about 70%.

## Inputs to collect first
Ask the user for anything below that they haven't already given you. Don't guess missing facts.

- Package.json / requirements file / CI config, or list the tools
- Tests / build / CI
- CTO / team lead

## Instructions

Do the task below with the user's inputs in place of each [bracket].

Here is our current dev stack and toolset: [paste package.json / requirements file / CI config, or list the tools]. Find faster or better replacements that developers are adopting right now (example swaps: pip -> uv, node -> bun, eslint -> a faster linter). For the top [3] candidates, try each one on a separate branch, run our [tests / build / CI], and measure the difference (time, size, errors). If a swap is a clear win, write a short, no-fluff summary for [CTO / team lead]: the gains in a table with percentages, a step-by-step migration guide, and the drawbacks. Don't merge anything; leave every change for review.

## Safety checks (share these with the user)

- Don't let AI make the final call on hiring, pay, performance or discipline. Use it to organise information, and have a person decide using criteria you can explain.
- Check names, dates, numbers and any claim against your own source material before you use the answer. AI can misread or invent details.
- Say clearly which parts need a person to review or approve before anything is sent, paid, posted or filed.
