Claude Code 2.1.317 adds an email check and blocking hook callbacks
The point
Anthropic released Claude Code v2.1.317. It adds a check that asks before a web or shell tool call sends your account email address to the network.
Why it matters
Builders get a clearer guardrail before private data leaves the machine through a tool call.
Key details
- Added onFailure block for Agent SDK hook callbacks, so a failed callback blocks the action instead of letting it run
- Added a warning to /schedule when a new cloud scheduled task gets connectors you did not ask for, with how to remove them
