DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Git Sparse-Checkout for Marketplace Plugins

What

New --sparse CLI option and sparsePaths config field for marketplace plugin installation, enabling cone-mode sparse-checkout for monorepo plugin sources.

Usage
claude plugin marketplace add my-marketplace --sparse .claude-plugin plugins
Details
  • Uses git sparse-checkout in cone mode to clone only specified directories
  • Useful for monorepos where the marketplace lives in a subdirectory
  • Combines --filter=blob:none for blobless clones with sparse-checkout for minimal disk usage
  • If sparsePaths is removed from config but the repo is already sparse, triggers a re-clone for full checkout
Evidence

CLI option definition (search for "--sparse <paths...>", "sparse-checkout", "sparsePaths")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
