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.

Plugin downloads write straight into the cache

Plugins

Plugin downloads stream straight into the cache and are hashed on the way in.

What

Files a marketplace plugin pulls down are now streamed directly into the cache and hashed on the way in, instead of first landing in a temporary staging directory. The expected checksum is still verified at the end, and a download that is too large fails rather than filling the cache.

Details
  • The write refuses to overwrite an existing entry and uses file mode 384 (owner read/write only) with a size cap.
  • If two sessions fetch the same asset at once, the loser re-checks the digest of what is already there and treats it as a cache hit.
  • Storage failures are reported as asset_transient or asset_too_large.
Evidence

asset-cache

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