Source Intelligence

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.

Marketplace Seed Directory Support

What

New CLAUDE_CODE_PLUGIN_SEED_DIR environment variable for pre-populating marketplace plugins in managed/enterprise environments.

Details
  • Reads known_marketplaces.json from the seed directory
  • Syncs seed marketplaces into the user's configuration with autoUpdate: false
  • Supports seed-managed plugin caches and external plugin caching
  • Seed-managed marketplaces are marked read-only and cannot be overwritten by user operations
Evidence

Seed directory function (search for "CLAUDE_CODE_PLUGIN_SEED_DIR", "marketplace(s) from seed dir")

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