What
A remote tool call is an action Claude runs on another machine, a host. This handling changes in several ways:
- On resume, a call can take over an existing standing request instead of starting a new one, and withdraws it if the call is cancelled.
- A result that arrives late can now be corrected to 'still_running', with a quiet period after a stop.
- A host whose epoch has changed is marked 'host_restarted', recorded as 'source: inferred' because it is deduced, not reported.
- Hosts are only asked about outcomes if Claude Code has a connection to them.
This area involves the tengu_remote_tool_targets gate, a server-controlled switch.
Why
Interrupting a resumed remote call can withdraw the work it took over, and a restarted or still-busy host is reported as such.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what a standing request is or what a user sees when one is withdrawn.
