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 validation flags unsafe archive credential setups

Marketplace validation now warns about unsafe headersHelper and missing sha256 setups.

headersHelperheaderssha256
What

Catalog validation gained errors and warnings for fetch credentials: an entry using headersHelper must inline its full manifest or the helper will not be run, headers/headersHelper on non-archive sources warn as ineffective, and an archive fetched with a helper but no sha256 warns.

Details
  • Routing and identity headers are reported as dropped at download time rather than silently discarded.
Evidence

An entry with headersHelper must inline its full manifest

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