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.

Under zero data retention, the file-send tool no longer appears at all.

Feature flag
tengu_send_user_file Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.223: off

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.223. It isn't a statement about your account. What a flag value here can and cannot tell you

What

Under a zero data retention policy the send-file tool is no longer offered, and the tool now checks the privacy policy itself rather than relying only on its feature gate.

Details
  • The privacy-policy denial table gained the pair ["zdr", "allow_send_file"] alongside the existing hipaa entry.
  • The user-file-send tool's isEnabled() short-circuits on the policy check before consulting its gate, Qe("tengu_send_user_file", !0), which otherwise defaults to true.
  • Cross-machine file transfer already surfaced a message about provider and privacy configuration; the tool now simply disappears under ZDR.
Evidence

["zdr", "allow_send_file"]

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