# Objective - Fixes #59409. Closes FR-143. Zed's managed npm directory reaches 10–17GB on machines that use external agents, and is never pruned. - Two independent causes: registry agents are launched with `npm exec`, which keys its install directory on the requested version, so every agent release leaves a full ~250MB copy behind; and npm never evicts anything from its download cache. ## Solution - Install registry agents into a directory we reuse, so npm replaces the previous version in place instead of accumulating one copy per release. As a side effect, updates now download only the changed dependencies rather than the whole tree. - Empty the download cache on startup. Nothing in it needs to survive a restart, since packages are installed elsewhere. It has to go wholesale: deleting individual downloads leaves npm's index pointing at missing files, and npm then fails with `ENOENT` rather than fetching them again. - The first launch after this does one full agent install as it moves into its new home, and reclaims whatever the old directories were holding. ## Testing - Installed the real agent at 0.33.1, then upgraded to 0.42.0 in the same directory: 253MB → 256MB, against two separate copies today. The resolved executable answers an ACP `initialize`. - macOS only. Windows deserves a look — it should be better than before, since the agent is now launched as a plain `.js` file with Node instead of through npm's `.cmd` shim, but I can't verify it. ## Self-Review Checklist: - [x] I've reviewed my own diff for quality, security, and reliability - [x] Unsafe blocks (if any) have justifying comments - [x] The content adheres to Zed's UI standards ([UX/UI](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) and [icon](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md) guidelines) - [ ] Tests cover the new/changed behavior - [x] Performance impact has been considered and is acceptable --- Release Notes: - Fixed the bundled npm cache growing without bound, which could consume many gigabytes of disk. |
