Claude Code v2.1.223 ·

Stream close with a parked question can now abort the in-flight query

Closing input while a question is pending can cancel the running query, once a remote setting says so.

The abort-on-close callback is wired at the CLI entry point but only selected when the gate reads "interrupt"; the fallback is "off".

What

When the input stream closes while can_use_tool requests for the parked-question tool are still pending, the pending request ids can now be collected and used to abort the current query with a shutdown reason.

Details
  • the control session gained an onStreamClosedWithParkedQuestion callback plus a setter, wired at the CLI entry point to abort the query
  • selected only when the gate resolves to the string "interrupt"
  • the in-source fallback is "off", which keeps the older preserve/no-op behaviour; real values come from remote config

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: not a boolean we can read

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.

What has happened since
Flag reading moved The flag server now returns "interrupt" for tengu_cinder_swift, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
