# Duplicate tools and stale caches

Prompt · Infrastructure and environment · I01

Finds disk space and confusion spent on duplicate developer tools and stale saved files on your computer.

## Prompt

```text
Inventory the development environment's browser runtimes, caches, SDKs, package managers, and duplicate installations. Identify obsolete or wasteful components, assess dependencies, and propose a safe cleanup.
```

**What it returns:** Each component with size, version, what depends on it, and whether deleting it is safe and reversible.

**Skip it when:** When disk space is fine and builds are stable.

**Tools:** A terminal on your computer.

**Watch for:** Treat every deletion as a proposal. Shared runtimes break other apps silently.

**Changes:** Changes nothing

**Sessions:** One session
