What’s New in Claude Code 2.1.317: /schedule Flags Extra Connectors, and Hooks Can Fail Closed

Claude Code 2.1.317 has some nice safety changes.

Safety

• /schedule warns when a new cloud scheduled task gets connectors you didn’t ask for, and shows how to remove them
• It asks before a web or shell tool call sends your account email address to the network
• Agent SDK hook callbacks get onFailure: "block", so a failing callback blocks the action instead of letting it through
• A notice when auto mode’s check has no answer for a subagent’s tool call

Also

• A cost report endpoint on the Claude apps gateway admin API
• Fixes for project and local MCP servers disconnecting after the first turn, and for claude auth status exiting before a slow token refresh was saved

My take

Hooks failing closed is the right default for anything that guards an agent.

Review before you install: read the release notes yourself, back up your config, and try new versions somewhere you can afford to break first.

God Bless, and Happy hacking!
