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.

npm package names are checked for path traversal

Under the hood
Useful2 Signal1
Plugins

npm package names are now rejected if they contain path traversal characters.

What

Package names are now validated against a schema that rejects anything containing .. or // and requires a valid scoped or unscoped npm name shape.

Details
  • The rejection message is "Package name cannot contain path traversal patterns".
Evidence

Package name cannot contain path traversal patterns

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