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.

Claude Code v2.1.223

File-upload gate for bridge attachments

You'll notice
Useful3 Signal0
Remote Control

Attachment uploads are now refused with a clear reason when policy or privacy settings forbid them.

What

Attachment uploads are now prechecked and refused with an explanatory error when sending file contents to Anthropic servers is not permitted.

Details
  • refuses when the provider is not first-party, when the privacy configuration restricts traffic, or when the allow_send_file policy denies
  • a policy cache miss also denies rather than falling through
  • outcomes are logged under bridge_attachment_upload with reasons not_first_party, essential_traffic, policy_cache_miss and policy_denied
Evidence

upload disabled: uploading file contents to Anthropic servers is not permitted on this API provider

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